CATTLE DENTITION:
❖ Cattle first develop 20 temporary teeth, known also as deciduous, milk, or baby teeth.
❖ These temporary teeth eventually fall out and are replaced with 32 permanent or adult
teeth as an animal matures. Temporary teeth are easily distinguishable from permanent
teeth. They are much smaller and whiter than permanent teeth.
Temporary teeth: 8 incisors, 12 Premolars, No molars
Permanent teeth: 8 incisor, 12 premolars, 12 molars (RRB SO-2019)
FINDING THE AGE OF ANIMALS:
1. General Appearance: - Young animal has shiny eyes, horns small and shiny, skin
drawn, developed ions, medium sized teeth and agile nature.
2. Seeing the hoof: - It is detected by looking at the condition of the hooves. The hooves
of young animals are small and shiny.
3. By horn:- Formula :- 2+ Number of rings on horn
The first ring on the horns is formed on the horns of the animal in the third year after
birth after this a ring is formed every year. It is wrong to estimate the age by this
method because with the help of sand, the cattle keepers gnaw the rings made on the
horns.

➢ The age of the animal is determined only by the incisor teeth only. Canine teeth are
not found in ruminant animals.

ANIMAL BREEDING
➢ Breeding: the mating and production of offspring by animals is known as breeding.
➢ When breeding is between animals of the same breed it is called inbreeding, while crosses
between different breeds are called outbreeding.
❖ Types of Breeding
➢ Inbreeding/ Close Breeding: Mating of closely related animals in the same breed such as
brother – sister mating, parents offspring mating. When the mates have common ancestors -
within 4 generations this results in inbreeding.
• Advantage: A pure line of a particular breed can be maintained
• Disadvantage: Loss of vigor, size, production fertility problems (Inbreeding depression)
➢ Out breeding: Mating of unrelated animals in the different breeds but with no common
ancestor for a minimum of 4-6 generations.
➢ Out-crossing: This is the practice of mating of animals within the same breed but having no
common ancestors on either side of their pedigree up to 4-6 generations.
➢ The offspring of such a mating is known as an outcross. It is the best breeding method for
animals that are below average in productivity in milk production, growth rate in beef cattle,
etc. A single outcross often helps to overcome inbreeding depression.
➢ Line Breeding: Mating of half-brother and half-sister, Cousin, increase homozygosity and
decrease heterozygosity (AFO-2020)
➢ Crossbreeding: In this method, superior males of one breed are mated with superior females
of another breed. Crossbreeding allows the desirable qualities of two different breeds to be
combined. Hisardale is a new breed of sheep developed in Punjab by crossing Marino rams
and Bikaneri ewes. (RRB SO-2019)
➢ Triple cross: In this method three breeds are crossed in a rotational manner it is also called
rotational crossing.
➢ Back Cross: Mating of a cross breed back to one of the pure parents. (JRF)
➢ Test Crossing: Breeding of the dominant phenotype with the homozygous recessive
phenotype (parent) is known as a test cross. The F1 hybrid is crossed with a recessive
genotype.
➢ Grading up: It is mating of pure-bred males of a established breed with nondescript females
successively over several generations to produce a progeny that resembles and performs
similar to the pure breed. Godavari breed of buffalo is developed by crossing of the local
buffalos of coastal region of Andhra Pradesh breed with Murrah breed over several
generations. (RRB SO-2021)
➢ Rotational crossing: In rotational crossing, males from one of the pure breeds are used in
alternate generations to breed the cross bred females. This rotational crossing could be

Agri Coaching Chandigarh 15


between two breeds is called crisscrossing ((AFO-2021) and among three breeds is called
triple crossing.
➢ Interspecific hybridization: In this method, male and female animals of two different related
species are mated. In some cases, the progeny may combine desirable features of both the
parents, and may be of considerable economic value, e.g., the mule
Outbreeding Outcrossing
1. Out breeding is breeding of unrelated 1. It is the cross of unrelated individual,
animals. same breed, no common ancestor
2. It can involve outcrossing or cross
breeding or interspecific hybridization.

Diestrum: (14 days)

16 Agri Coaching Chandigarh


❖ Proestrum: (2 days) Period of building up growth of graffian Follicle which helps for the
nourishment of ovum fluid contains hormone called “oestrogen”. It causes changes in uterus,
blood supply.
❖ Oestrum: (1 day) during which the female is ready to receive male.
❖ Metoestrum:(4 days) Implantation of the embryo takes place, corpus luteum takes place.
Prevents the growth of graffian follicle thereby arrests oestrus cycle. (RRB SO-2018)
❖ Diestrum: (14 days) further development of uterus takes place. If the animal has not
conceived involution of uterus take place.
❖ Estrus Period: Pro estrus: 2 or 3 days, Estrus: 12 to 18 hours, Ovulation: 12 to 16 hours after
end of estrus, Estrous cycle: 21± 3 days

Symptoms of Heat in Animal


➢ The animal will be excited condition. The animal will be in restlessness
and nervousness.
➢ The animal will reduce the intake of feed and milk production.
➢ Peculiar movement of limbo sacral region will be observed.
➢ The animals which are in heat will lick other animals and smelling other
animals.
➢ The animals will try to mount other animals
➢ The animals will stand still when another animal try to mount. This period
is known as standing heat. This extends 14-16 hours.
➢ Frequent maturation (urination) will be observed.
➢ Swelling of the valva will be seen.
➢ The tail will be in raised position.

RECOMMENDATION FOR TIMING OF INSEMINATION:


Cows showing oestrus Should be inseminated Too late for good results
In morning Same day Next day
In afternoon Morning of next day or early After 3 p.m.
afternoon

CASTRATION
❖ Making the animal unable to reproduce is generally known as castration.
❖ Precaution: Castration should be performed during cold season and strictly avoid rainy
season for fear of fly problems.
❖ Optimum Age: Young animals: within 3 months (Surgical method and elastrator)
❖ Adult animal: within one year of age (Closed method – Burdizzo castrators)
❖ Methods of castration:
1. Burdizzo method
➢ It is also known as bloodless castration.
➢ This method is safe, quick and less chance of getting infection.
2. Open or surgical method
➢ Scrotum is opened and testicles are removed, aseptically and the wound is treated with
antiseptics.
3. Rubber ring or elastrator method
➢ A strong and tight rubber ring placed around the cord at an early age of calf.
➢ Optimum age: below 3 months.
❖ Semen collection methods:
❖ Artificial vagina (A.I.)
➢ A.I. was first attempted in India in 1939 by Dr. Sampath kumar at the palace dairy
farm, Mysore.
➢ The first buffalo calf through A.I. was born in 1943 at the Allahabad Ag. Institute in
U. P. in India.
➢ Internal temperature of vagina is around 40–45°C
➢ Sperm are viable for 24 hours in the female reproductive tract whereas the ovum
remains fertile for only about 10 hours after ovulation.
❖ Storage of frozen semen:
(a) -79o C by using solid CO2 (dry ice) and alcohol
(b) -196o C by using liquid nitrogen (mostly used)
(c) -296o C by using liquid helium

DIGESTIVE SYSTEM OF CATTLE (RUMINANTS)


1. The digestive organs of ruminants consist of mouth, oesophagus, rumen, reticulum,
omasum and abomasum, small intestine, and large intestine.
2. The cow takes food into the mouth. The food taken in by the animal after mixing with
saliva enters into the rumen through oesophagus.
3. Cattle stomach has four compartments such as:
➢ Rumen: In the rumen the feed is subjected to microbial fermentation. In ruminants this
enlarged part is represented by the rumen which is the biggest compartment in their four-
chambered stomach. The temperature of rumen is 38- 40°C. This is ideal for the growth
of micro-organisms, and they flourish as if grown in an incubator. (BHU)
➢ Reticulum: It is a smaller sac partially separated from rumen. This organ has a thick wall
resembling honeycomb. The contents of rumen and reticulum mix freely. Reticulum is

34 Agri Coaching Chandigarh


connected to omasum, the third compartment of stomach through an opening on the right
side of reticulum.
➢ Omasum: This organ has many layers of muscular leaves giving it the resemblance to a
book. After fermentation the ingest passes through the reticulo-omasal orifice into the
omasum. With the help of the muscular leaves having horny papillae the ingesta is
squeezed out. Water and fatty acids so squeezed out are absorbed. (JRF)
➢ Abomasum: it is the true stomach in the ruminant. From this organ onwards the
digestion taking place in ruminants is similar to that of non-ruminants. (JRF)

MILKING METHODS:
➢ MILKING: Milking is defined as the critical and laborious process which involves hormonal
reflex. The art of milking performed within 5-8 minutes. Normally milking is done twice a
day. Milking methods are:
➢ FISTING/FULL HAND METHOD: It is the best method of hand milking though most of
the milkmen follow knuckling method. (BHU,Pre-PG)

54 Agri Coaching Chandigarh


➢ KNUCKLING METHOD: Many milkers tend to bend their thumb against the teat canal and
drag the milk out. This practice should be avoided as it is injurious to the teat.
➢ STRIPPING: This method is followed where the length of the teat is small; it is normally
practiced towards the end of milking in order to evacuate the milk completely
➢ MACHINE MILKING: A calf and the machine do the harvesting of milk in a similar
fashion. One milking machine for – 10 animals yielding 10 liters / day will be economical to
maintain.
MILK PROCESSING
1. Homogenization: to prevent creaming, or the rising of fat to the top of the container of milk.
The process of homogenization breaks the fat particles into smaller particles. (AFO-2021)
2. Pasteurization:
Temperature Time Pasteurization Type
63°C 30 minutes Batch Pasteurization (LTLT)/ Holding or
Batch method (JRF)
72°C 15 seconds High Temperature Short Time
Pasteurization (HTST)/ continuous system
or flash pasteurization

GENERAL INTRODUCTION

Agricultural engineering is the engineering discipline that studies agricultural production and
processing. Agricultural engineering combines the disciplines of mechanical, civil, electrical
and chemical engineering principles with a knowledge of agricultural principles according
to technological principles.

SOURCES OF FARM POWER:

1) HUMAN POWER-An average man can develop maximum power of about 0.1 hp for doing
farm work. A strong man can develop maximum power of about 75 watts (about 0.1 hp) for
doing farm work. The average human power availability in sustained working are as follows:

Male : 60 watts
(0.06 kW)

Female : 48 watts
(0.048 kW)

Children : 30 watts
(0.030 kW)

2) ANIMAL POWER
➢ Power developed by an average pair of bullocks about 1 hp for usual farm work.
➢ The average force a draft animal can exert is nearly one-tenth of its body weight.
➢ 1 HP=750 watt
3) MECHANICAL POWER:

These engines are two types:


(a) Spark ignition engines (Petrol or Kerosene engine)
(b) Compression ignition engines (Diesel engines)

The thermal The thermal


efficiency of petrol efficiency of diesel
engine varies from 25 engine varies from 32
to 32 per cent to 38 per cent

TRACTOR

Tractor are available in following classes, depending upon horsepower (hp):

20 to 30 hp – About 25% of the total production of tractors in India.

31 to 40 hp – About 60% of the total production of tractors in India.

41 to above – About 15% of the total production of tractors in India.

❖ Tractor production started in India in 1961. The first tractor manufacturer “M/S Eicher
Goodearth” Produced “Eicher” tractors at Faridabad.
❖ Average command area of a tractor (26.1 kW) is about fifteen hectares. For calculating power
availability from tractor on the farm, a weighted average of 26.1 kW power per tractor is
considered.

SELECTION OF TRACTOR:

1. LAND HOLDING: Under a single cropping pattern, it is normally recommended to


consider 1 hp for every 2 hectares of land. In other words, one tractor 20 – 25 hp is suitable
for 40 hectares farm.
2. CROPPING PATTERN: Generally, 1.5 hectare/hp has been recommended where
adequate irrigation facilities are available and more than one crop is taken. So, a 30 – 35 hp
tractor is suitable for 40-hectare farm.

POWER TILLER

For calculating power availability from power tiller on the farm, a weighted average of 7 kw
per unit is considered. Average command area of a power tiller (7.46 kw) is five hectares,
where one pair of bullocks can command about two hectares only.
✓ Came in the world - 1920
✓ Introduced in India - 1963 ( AFO 2018)
✓ Japan is the first country to use power tiller on large scale.
✓ Tyre pressure: 1.1 to 1.4 kg/cm2 or 15.5 to 20 psi

74 Agri Coaching Chandigarh


STATUS OF FARM POWER IN INDIA

❖ About 75% farm holding belong to small and marginal farmers.


❖ About 25% belong to semi, medium and large farm holders.

AVERAGE COMMAND AREA

One pair of
draught animals:
2 ha
Power tiller (7.46
kw): 5 ha

Tractor (26.1
kw):15 ha

For 1000 hectares of cultivated land, the bullocks, power tiller and tractors are generally
required as follows:

Bullocks: 500 Power


Tractor:67
pairs tiller:200

Studies have shown that about 54% energy in crop production comes from direct sources
like:

Mechanical Electrical
power power

Human Draught
power animals

➢ Engines,
➢ Electric motors,
➢ Grain processing and
➢ Hauling equipment’s.
❖ The level of farm mechanization in India stands at about 40-45%.
❖ This level of farm mechanization is still low as compared to the countries such as the U. S.
(95 %), Brazil (75%) and China (57%).
❖ Use of improved implements has potential to increase productivity up to 30 per cent and
reduce the cost of cultivation up to 20 per cent.

GOV CONTRIBUTION TO INCREASE LEVEL OF FARM MECHANIZATION

❖ Sub Mission on Agricultural Mechanization (SMAM)


➢ Centrally sponsored scheme for promotion of farm mechanization.
➢ launched by the Ministry of Agriculture and Farmers Welfare in the year 2014-15 for a
period of five years.
➢ Increasing the reach of farm mechanization to small and marginal farmers and to the regions
where availability of farm power is less
NOTE – Subsidies under this scheme will be added your current affairs part.

EMERGING TRENDS IN FARM MECHANIZATION

CLASSIFICATION OF HEAT ENGINES

1. Based on combustion of fuel:

External combustion engine

Internal combustion engine

a) External combustion engine-

➢ Here, the working medium, the steam, is generated in a boiler, located outside the engine
and allowed into the cylinder to operate the piston to do mechanical work.

b) Internal combustion engine-

➢ In internal combustion engine, the combustion of fuel takes place inside the engine
cylinder and heat is generated within the cylinder.

➢ This heat is added to the air inside the cylinder and thus the pressure of the air is
increased tremendously.

➢ This high-pressure air moves the piston which rotates the crank shaft and thus
mechanical work is done

2. Based on fuel used:

Diesel engine – Diesel is used as fuel

Petrol engine – Petrol is used as fuel

Gas engines – propane, butane or methane gases are


used

3. Based ignition of fuel-

Spark ignition engine (Carburetor type engines)

Compression ignition engine (injector type engines)

82 Agri Coaching Chandigarh


a) Spark ignition engine – a mixture of air and fuel is drawn into the engine cylinder. Ignition
of fuel is done by using a spark plug.

➢ The spark plug produces a spark and ignites the air- fuel mixture.
➢ Such combustion is called constant volume combustion (C.V.C.)

b) Compression ignition engine –

➢ In compression ignition engines air is compressed into the engine cylinder.


➢ Due to this the temperature of the compressed air rises to 700-900 oC. At this stage diesel
is sprayed into the cylinder in fine particles.
➢ Due to a very high temperature, the fuel gets ignited. This type of combustion is called
constant pressure combustion (C.P.C.) because the pressure inside the cylinder is almost
constant when combustion is taking place.

4. Based on working cycle-

Four stroke cycle engine

Two stroke cycle engine

a) Four stroke cycle engine- When the cycle is completed in two revolutions of the
Crankshaft, it is called four stroke cycle engines.
b) Two stroke cycle engine- When the cycle is completed in one revolution of the Crankshaft,
it is called two stroke cycle engines.

POINTS ABOUT IC ENGINE:

❖ The end of the connecting rod connecting the piston is called small end.
❖ The other end of the connecting rod connecting the crank shaft is called big end.
❖ When piston is moved up and down, the motion is transmitted to the crank shaft by the
connecting rod and the crank shaft makes rotary motion.
❖ The crankshaft rotates in main bearings which are fitted the crankcase.
❖ A flywheel is provided at one end of the crankshaft for smoothing the uneven torque
produced by the engine.
❖ There is an oil pump at the bottom of the engine which contains lubricating oil for lubricating
different parts of the engine. The oil pressure in hydraulic pump caries from 150 to 200
kg/cm2.

➢ It is estimated that a tractor engine requires to be operated at full load approximately 25 to
30 percent of the operating time. Most of the time, the engine is required to be operated
between 50 to 70% of the full load.
➢ The minimum specific fuel consumption occurs at speed of 1650 rpm.

POWER TRANSMISSION SYSTEM

A power transmission system usually consists of the following parts:

❖ Clutch – The device that connects or disconnects two torque transmitting devices.
❖ Transmission – A device for transmitting power at a multiplicity of speed and torque.
❖ P.T.O. Drive – The parts that transmit torque from the engine to the PTO spline on the rear
of the tractor.
❖ Differential – The device, usually in the axle housing, that allows the two wheels on an axle
to rotate at different speeds.
❖ Brake – The device, usually in the axle housing, that stops the motion of the tractor.
❖ Axle – The shaft and connecting parts that transmits torque from the differential or final gear
reduction to the wheels.

Piston rings are of two types:
1. Compression ring and
2. Oil ring
➢ Oil ring: It control the distribution of lubrication oil in the cylinder and the piston.

➢ Crankshaft:It is the main shaft of an engine which converts the reciprocating motion
of the piston into rotary motion of the flywheel.
❖ Usually, the crankshaft is made of drop forged steel or cast steel.
➢ Flywheel is made of cast iron.
❖ Its main functions are stores energy during power stroke and returns back the energy
during the idle strokes, providing a uniform rotary motion of flywheel, pressure surfaces
for the clutch plate and Sometime the flywheel serves the purpose of a pulley for
transmitting power.
➢ Crankcase provides a reservoir for the lubricating oil. It is a mounting unit for such
accessories as the oil pump, oil filter, starting motor and ignition components.
➢ Camshaft is a shaft which raises and lowers the inlet and exhaust valves at proper times.
❖ The speed of the camshaft is exactly half the speed of the crankshaft in four stroke
engines.
❖ Camshaft operates the ignition timing mechanism, lubricating oil pump and fuel pump.
❖ It is mounted in the crankcase, parallel to the crankshaft.
➢ Scavenging: The process of removal of burnt or exhaust gases from the engine cylinder is
known as scavenging.

PROTECTED CULTIVATION

Green House: A greenhouse is a framed or an inflated structure covered with a transparent or


translucent material in which crops could be grown under the conditions of at least partially
controlled environment and which is large enough to permit persons to work within it to carry
out cultural operations.

Greenhouse Effect: Phenomenon of increase in the ambient temperature, due to the formation
of the blanket of carbon dioxide is known as greenhouse effect.

➢ In general, the percentage of carbon dioxide in the atmosphere is 0.035% (345 ppm).
➢ During the daytime, the shorter wave radiation enters into the greenhouse and gets reflected
from the ground surface.
➢ This causes the increase in the greenhouse temperature.
➢ It is desirable effect from point of view of crop growth in the cold regions.

GREENHOUSE TYPE BASED ON SHAPE:

1. Lean-to type greenhouse: A lean-to design is used when a greenhouse is placed against the
side of an existing building
➢ It is typically facing south side and a total width of 7 to 12 feet.
2. Even span type greenhouse: The even-span is the standard type and full-size structure, the
two roof slopes are of equal pitch and width
➢ Several single and multiple span types are available for use in various regions of India.
➢ For single span type the span in general, varies from 5 to 9 m, whereas the length is
around 24 m.
➢ The height varies from 2.5 to 4.3 m.
3. Uneven span type greenhouse: This type of greenhouse is constructed on hilly terrain and
now-a-days as it is not adaptable for automation.
4. Ridge and furrow type greenhouse: Designs of this type of use two or more A-frame
greenhouses connected to one another along the length of the eave.
➢ The eave serves as furrow or gutter to carry rain and melted snow away.
➢ Effectively used in northern countries of Europe and in Canada and are well suited to the
Indian conditions.
5. Saw tooth type Greenhouse: These are also similar to ridge and furrow type greenhouses
accept that, there is provision for natural ventilation in this type.

GREENHOUSES FOR ACTIVE COOLING:

❖ During summer season, it is desirable to reduce the temperatures of greenhouse than the
ambient temperatures, for effective crop growth.

Agri Coaching Chandigarh 95


❖ This greenhouse is designed in such a way that it permits a roof opening of 40% and in some
cases nearly 100%.
1. Wooden framed structures: In general, for the greenhouses with span less than 6 m, only
wooden framed structures are used (Pine wood)
2. Pipe framed structures: Pipes are used for construction of greenhouses, when the clear
span is around 12m
3. Glass greenhouses: Only glass greenhouses with glass as the covering material existed
prior to 1950.
4. Plastic film greenhouses: Flexible plastic films including polyethylene, polyester and
polyvinyl chloride are used as covering material in this type of greenhouses. The best
quality ultraviolet (UV) stabilized film can last for four years only.
5. Rigid panel greenhouses: Polyvinyl chloride rigid panels, fibre glass-reinforced plastic,
acrylic and polycarbonate rigid panels are employed as the covering material. High grade
panels have long life even up to 20 years.
6. Shading nets: They are characterized of high tear resistance, low weight for easy and
quick installation with a 30-90% shade value range.

LIGHT:

Green house crops are subjected to light intensities varying from 129.6klux on clear summer
days to 3.2 Klux on cloudy winter days. Photosynthesis does not increase at light intensities
higher than 32.2klux.

➢ UV light is available in the shorter wavelength range, i.e less than 400nm. Large of
quantities of it is harmful to the plants.
➢ Glass screens are opaque to the most UV light and light below the range of 325nm.
➢ Visible and white light has wavelength of 400 to 700nm.
➢ Far red light (700 to 750nm) affects plants, besides causing photosynthesis.

Relative humidity: For most crops, the acceptable range of relative humidity is between 50 to
80%.

Ventilation: Air temperatures above 35 0C are generally not suited for the crops in green house.

Carbon dioxide: Most crops will respond favorably to Co2 at 1000 to 1200 ppm.

EQUIPMENT REQUIRED FOR CONTROLLING GREENHOUSE ENVIRONMENT:

1. Fan-and Pad cooling system: The fan and pad evaporative cooling system has been
available since 1954 and is still the most common summer cooling system in green houses.

96 Agri Coaching Chandigarh


2. Fog cooling system: The fog evaporative cooling system, introduced in green houses in
1980, mean size of less than 10 microns using suitable nozzles.
3. Natural ventilation: The ventilators on the roof as well as those on the side wall accounts,
each about 10% of the total roof area.
4. Computers: Computer systems can provide fully integrated control of temperature,
humidity, irrigation and fertilization, CO2, light and shade levels for virtually any size
growing facility. to realize saving of 15 to 50% in energy, water, chemical and pesticide
applications.

PLANNING OF GREEN HOUSE FACILITY:

❖ Structural design: Greenhouse structures should be designed to resist a 130 km/h wind
velocity.
❖ Covering materials:

Covering material Life span


1. Glass and acrylic sheet 20 years
2. Polycarbonate and fiberglass-reinforced polyester sheet 5-12 years
3. Polyethylene 2-6 months
4. Polyethylene stabilized for UV rays 2-3 years

The ideal greenhouse selective covering material should have usable life of 10 to 20 years.

MATERIALS FOR CONSTRUCTION OF GREEN HOUSES

a) Wood: Wood and bamboo are generally used for low cost poly-houses.
b) Glass: Widely used glass for greenhouse is:

(i) Single drawn or float glass (thickness of 3 to 4 mm)

(ii) Hammered and tempered glass (thickness of 4 mm) the most widely used

c) Polyethylene film: Polyethylene film was developed in the late 1930s in England and spread
around the middle of this century. Plastic film greenhouses are popular because the cost of
heating them is approximately 40% lower compared to single-layer glass or fiberglass-
reinforced plastic greenhouses.
d) Polyvinyl chloride film: PVC films are UV light resistant vinyl films of 0.2 to 0.3 mm and
are guaranteed for 4 to 5 years respectively. In Japan, 95% of greenhouses are covered with
plastic film, out of which 90% are covered with vinyl film.
e) Tefzel T 2 film: The most recent addition of greenhouse film plastic covering is Tefzel T 2
film (ethylene tetrafluoroethylene).

Agri Coaching Chandigarh 97


f) Polyvinyl chloride rigid-panel: PVC rigid panels showed much promise as an inexpensive
covering material (almost 40% of cost of long-lasting fiberglass reinforced plastics), has the
life of 5 years. PVC rigid panels are not in use.
g) Fiberglass-reinforced plastic (FRP) rigid panel: FRP was more popular as a greenhouse
covering material in the recent past. Some grades give 5 to 10 years, while better grades
can last up to 20 years.
h) Acrylic and polycarbonate rigid-panel: These panels have been available for about 15
years for greenhouse use. Acrylic panels are available in thickness of 16 and 18 mm and
have 83% of PAR light transmission.
i) Design criteria and constructional details of greenhouses: The floor area of service
buildings required for small firms is about 13% of the greenhouse floor area, (An average
10%)

IRRIGATION SYSTEM USED IN GREENHOUSES

❖ Rules of Watering:
➢ Use a well-drained substrate with good structure
➢ Water thoroughly each time- As a rule, 10 to 15% excess of water is supplied
1. Hand watering: The most traditional method of irrigation is hand watering and in present
days is uneconomical.
2. Perimeter watering:
➢ Perimeter watering system can be used for crop production in benches or beds.
➢ A typical system consists of a plastic pipe around the perimeter of a bench with nozzles
that spray water over the substrate surface below the foliage.
➢ Either polythene or PVC pipe can be used.
➢ Nozzles are made of nylon or a hard plastic and are available to put out a spray are of
180°, 90° or 45°.
3. Overhead sprinklers:
➢ While the foliage on the majority of crops should be kept dry for disease control purposes,
a few crops do tolerate wet foliage.
➢ A total height of 0.6 m is sufficient for bedding plants flats and 1.8 m for fresh flowers.
A nozzle is installed at the top of each riser.
➢ Nozzles vary from those that throw a 360° pattern continuously to types that rotate around
a 360° circle. Trays are sometimes placed under pots to collect water that would otherwise
fall on the ground between pots and wasted.
➢ The trays also have drain holes, which allow drainage of excess water and store certain
quantity, which is subsequently absorbed by the substrate.
4. Boom watering:

98 Agri Coaching Chandigarh


➢ Boom watering can function either as open or a closed system and is used often for the
production of seedlings grown in plug trays.
➢ Precision of watering is extremely important during the 2-to-8-week production time of
plug seedlings. A boom watering system generally consists of a water pipe boom that
extends from one side of a greenhouse bay to the other
➢ The boom is propelled by an electric motor.
5. Drip Irrigation:
➢ Drip irrigation, often referred to as trickle irrigation.
➢ Drip irrigation is the best means of water conservation. In general, the application
efficiency is 90 to 95%, compared with sprinkler at 70% and furrow irrigation at 60
to 80%.

SPRINKLER IRRIGATION LIMITATIONS:

❖ Power requirements are usually high, since sprinkler operate with a water pressure of 0.5
kg/cm2 to 10 kg/cm2.
❖ PERFORATED PIPE SYSTEM
➢ It is suitable for lower pressure of about 0.5 to 2.5 kg/cm2.
➢ The laterals may design to operate under pressure as low as 0.15 to 0.2 kg/cm2 and as high
as 1 to 1.75 kg/cm2.
❖ EMITTERS:
➢ The discharge rate of “emitters” usually ranges from 2 to 10 litres per hour.
❖ EMERGING TRENDS IN FARM MECHANIZATION
➢ Small engines 1 to 3 hp for handheld and knapsack power operated equipment for pruning,
hedge trimming, tree felling, cutting of bushes, tea harvesting, spraying and dusting are
preferred.

OCCURRENCE OF GROUNDWATER

➢ In order to understand the occurrence of groundwater and its vertical distribution, let’s first
consider the hydrological zones present below the ground
➢ The zone between the ground surface and the top of capillary fringe is called unsaturated zone
(or, zone of aeration) which consists of voids (pores or interstices) partially filled with water
and partially with air.
➢ Water is held at a pressure less than the atmospheric pressure in the unsaturated zone.
➢ The zone between bottom of the unsaturated zone and top of the water table is called capillary
zone.
➢ the zone extending from the water table to an impermeable layer is called saturated zone (or,
zone of saturation), wherein all voids are completely filled with water.
➢ In saturated zone water is held at a pressure greater than the atmospheric pressure.

AQUIFER AND CONFINING LAYERS

➢ Aquifer is defined as “a single geologic formation or a group of geologic formations that can
transmit and yield water in usable quantities”
➢ Aquiclude is defined as a geologic formation that can store significant amount of water but
does not have the capability to transmit a significant amount of water. Clay is an ideal example
of aquiclude.
➢ Aquitard is defined as a geologic formation that can store some water as well as can transmit
water at a relatively low rate compared to aquifers. Sandy clay is an ideal example of aquitard.
➢ Aquifuge is defined as a geologic formation that can neither store nor transmit water. Solid
granite is an ideal example of aquifuge.

FURTHER AQUIFER CAN BE BASICALLY CLASSIFIED INTO THREE TYPES:

(a) unconfined aquifer,


(b) confined aquifer, and
(c) leaky aquifer.

Sometimes, fourth type of the aquifer is known as ‘perched aquifer’,

(a) Unconfined Aquifers Aquifers which are bounded by a free surface (known as ‘water
table’) at the upper boundary and a confining layer at the lower boundary are called
unconfined aquifers.
(b) Confined Aquifers Aquifers which are bounded both above and below by impervious or
semi-pervious layers are called confined aquifers and the water present in these aquifers are

106 Agri Coaching Chandigarh


under pressure (Aquifers 2 and 3 in Fig. 3.1). Confined aquifers are sometimes also called
‘pressure aquifers’ or ‘artesian aquifers.

(c) Leaky Aquifers If an aquifer (confined aquifer or unconfined aquifer) loses or gains water
through adjacent semi-permeable layers, it is called a ‘leaky aquifer’ ,Therefore, the terms
‘leaky confined aquifer’ and ‘leaky unconfined aquifer’ are widely used depending on
whether the leaky aquifer is confined or unconfined.

SURVEYING

➢ Surveying is the art of determining the relative positions of different objects on the surface
and below the surface of the earth by measuring the horizontal and vertical distances between
them and by preparing a map to any suitable scale.
➢ To prepare a topographical map which shows the hills, valleys, rivers, villages, towns, forests
etc. of a country.
➢ To prepare an engineering map showing details of engineering works such as roads, railways,
reservoirs, irrigation canals, etc.
The general principles of surveying are:

a. To work from the whole to the part, and


b. To locate a new station by at least two measurements (linear or angular) from fixed
reference points.

CLASSIFICATION OF SURVEYING

Generally, surveying is divided into two major categories: plane and geodetic surveying

(a) PLANE SURVEYING is a process of surveying in which the portion of the earth being
surveyed is considered a plane.
(b) GEODETIC SURVEYING is a process of surveying in which the shape and size of the
earth are considered

Chain Surveying The principle of chain surveying is triangulation. This means that the area
to be surveyed is divided into a number of small triangles which should be well conditioned.

Types of Chains used in Surveying


Depending upon the length of the chain, these are divided into following types,

1. Metric chains- Metric chains are the most used chain in India. These types of chains come
in many lengths such as 5, 10, 20 and 30 meters. Most used is 20m chain. Tallies are
provided at every 2m of the chain for quick reading. Every link of this type of chain is 0.2m.
The total length of the chain is marked on the brass handle at the ends.
2. Steel band or Band chain-These types of chain consist of a long narrow strip of steel of
uniform width of 12 to 16 mm and thickness of 0.3 to 0.6 mm. this chain is divides by brass
studs at every 20cm or instead of brass studs, band chain may have graduated engraving as
centimeter

108 Agri Coaching Chandigarh


3. Gunter’s chain or surveyor’s chain - Gunter chain comes in standard 66ft. This chain
consists of 100links, each link being 0.66ft or 7.92inches. The length 66ft is selected because
it is convenient in land measurements.
10 square Gunter’s chains = 1 Acre
10 Gunter chains = 1 Furlong
80 Gunter chains = 1 mile
4. Engineer’s chain- This chain comes in 100ft length. Its consist of 100 links each link being
1ft long. At every 10 links a brass ring or tags are provided for indication of 10 links.
Readings are taken in feet and decimal.
5. Revenue chain- The standard size of this type of chain is 33ft. The number of links are 16,
each link being 2 ft. This chain is commonly used in cadastral survey.

➢ Note that, to compute MC, we can use TC or TVC because fixed cost can’t be changed.

➢ Imp: MC curves intersect AVC and AC at their minimum points.

❖ Important points determining price elasticity of demands:


➢ Nature of commodity:
✓ Comforts, Ed = 1,
✓ Ed > 1

132 Agri Coaching Chandigarh


✓ Inferior goods, Ed < 1
➢ Availability of substitute:
✓ If substitute available demand elastic.
✓ If substitute not available inelastic.
✓ It is so because, if price of one substitute fall people will buy more of it.
➢ Goods with different uses: These goods have elastic demand. E.g., electricity has many
uses.
➢ Postponement of use: Goods whose demand can be postponed has high elastic demand like
gold.
✓ Whose amount can’t be postponed has less elastic demand.
➢ Income of consumer: People who are very rich or poor has inelastic demand because rise
or fall in prices has very little effect on their demand.
✓ While middle class people have elastic demand.
➢ Habit of consumer: Demand for habitual goods is inelastic. Eg.: Cigarette, coffee (Despite
rise in their price people demand such goods in same quantity).
➢ Time:
✓ In short period: Demand inelastic.
✓ In long period: Demand elastic.
✓ Because a person can change his habits in the long run.
➢ Relatively elastic demand:

✓ Ed > 1
✓ Generally, for luxuries.
➢ Relatively inelastic demand:

Agri Coaching Chandigarh 133


✓ Ed < 1
✓ Generally, for necessities.
➢ Unitary Elastic demand:

✓ Generally, for comforts.


➢ Supply curves:
✓ Production side
✓ Positive relation with price

❖ Equilibrium condition:

134 Agri Coaching Chandigarh


✓ Where demand + supply forces interest.
➢ Rural Credit: The word credit is derived from the Latin word Credo meaning ''I believe" or
I have confidence in". in economics, the term credit implies the postponement of payment.
Farm finance is concerned with the acquisition and management of capital in the farm
business.
❖ Classification of credit:
(i) Short term credit: It is given to meet current farm expenses such as purchase of seed,
manure and fertilizers, payment of wages to hired human labour etc. and repaid in 12
months.
(ii) Medium term credit: it is given for purchase of land, construction of farm building,
purchase of tractor and installation of tube wells etc. The period of long-term ranges from
12 month to 3-5 years.
(iii) Long Term credit: It is given to special projects and repayment period is more than 5
years.
➢ Agriculture Finance :- Credit is needed for adopting new technology, buying new
machines, such as a machine which is beneficial to the farmer to increase production, but
the farmer cannot buy it, in such a situation credit is needed.
✓ As 54% of country’s population dependent on agriculture/ production sector. Hence,
finance is needed to regulate all these activities.
✓ Agricultural Finance exist at both macro and Micro Levels.
✓ Macro Finance deals with the different sources of funds for agriculture as a whole in the
economy.
✓ Micro Finance deals with the financial management of individual farm businesses..
✓ Finance: Borrowed funds.
✓ Credit: Owned funds and borrowed funds.

AGRICULTURAL MARKETING
➢ The word market comes from the latin word marcatus, which means merchandise or trade or
a place where business is conducted. Word market has been widely and variedly used to
mean (a) a place or a building where commodities are bought and sold, e.g., supermarket; (b)
potential buyers and sellers of a product, e.g., wheat market and cotton market.
➢ "Marketing is the performance of all business processes, including the delivery of goods and
services from the initial agricultural production point to the final (consumer) point."
➢ Agricultural marketing is a process in which the seller of agricultural commodities wishes to
sell his goods and the buyer desires to buy that commodity at a fixed price.
❖ Utility:
➢ Marketing adds cost to the product; but, at the same time, it adds utilities to the
➢ product. The following four types of utilities of the product are created by marketing:
(a) Form Utility: The processing function adds form utility to the product by changing the raw
material into a finished form. With this change, the product becomes more useful than it is
in the form in which it is produced by the farmer.

138 Agri Coaching Chandigarh


(b) Place Utility: The transportation function adds place utility to products by shifting them to
a place of need from the place of plenty. Products command higher prices at the place of
need than at the place of production because of the increased utility of the product.
(c) Time Utility: The storage function adds time utility to the products by making them
available at the time when they are needed.
(d) Possession Utility: The marketing function of buying and selling helps in the transfer of
ownership from one person to another. Products are transferred through marketing to
persons having a higher utility from persons having a low utility.

2. Retail market
A. According to seller:
1. Primary market: These markets are held once or twice in a week and are generally
found in villages. Such markets are called Hats. In such markets producers directly sell
their commodities to the consumers and itinerant dealers or village banias.
2. Secondary market: These are daily markets and are held in cities. Generally, wholesale
of commodities takes place. Wholesalers, Kaccha and Pucca arhatiyas are present in
secondary market.
3. Terminal Market: such markets are found at seashore or ports. The agricultural products
are exported to the other countries by these markets.
B. According to time:
1. Daily market: Daily market is every short period market. The prices of agricultural
commodities are determined on the basis of variation in demand. Supply is limited.
Therefore, in equilibrium of demand and supply, the demand plays important role than
supply.
2. Short period market: Due to short period the demand is more effective on supply. In
short period market the supply of a commodity cannot be fully adjusted to the demand for
it.

140 Agri Coaching Chandigarh


3. Long period market: in long period the supply of commodity can be adjusted to the
demand for it. If the demand at a given price increases the production of commodity can
be increased in the long period.
C. According to competitions:
1. Perfect market: In perfect market there are a large number of buyers and sellers and free
competition among buyers and sellers. The buyers and sellers have full knowledge about
the price of the commodities sold at different places.
2. Imperfect market: Buyers and sellers do not complete freely between themselves due to
friendship. Sometimes the number of buyers and sellers are small.
They do not know the exact price of the commodities sold at different places.
3. Monopoly market: When there is a single producer or seller of a commodity, and that
commodity should not have any close substitutes it is said a monopoly market.
D. According to regulation:
1. Regulated markets: The markets are regulated under market regulation act. The
representatives of government, cooperative societies, traders and farmers make a
agricultural marketing society. These societies control all the marketing business.
Middleman etc are given license and all the marketing charges are fixed and metric
system of weighing is used.
2. Unregulated markets: Under such markets there is not any regulation of government.
All the marketing defects are present in such markets. Middlemen charge more amount
for their services.
E. According to area:
1. Local market: In such markets the buyers and sellers of a commodity carry on business
at a particular place. The markets for perishable commodities such as milk and vegetables
are largely local.
2. National market: In national market the buyers and sellers extend over the entire nation.
The market of food grains and cloths are of national type.
3. International market: in such markets the buyers and seller are of different countries.
The market for tea and jute is international.
F. According to function:
1. General or mixed market: the market in which articles of all sorts are offered for sale is
called general market.
2. Specialised market: In specialized market, a particular commodity is sold, e.g.,
vegetable market, fish market etc.

Agri Coaching Chandigarh 141


3. Marketing by samples: The samples of all goods offered for sale are sent for display.
For example, wheat, cotton, wool etc. are usually sold, by granding and sample. It is very
difficult for the buyer to inspect every single grain of wheat that he buys. It is very
difficult for a seller to transport all the goods to the marketplace. He there adopts the
method of selling goods by sample.
4. Marketing by grade: Marketing by sample leads to marketing by grade, The commodity
is divided into different grades on the basis of quantity or variety and each grade is given
certain name or trademark. The sellers can sell the commodity without showing samples
and purchasers can purchase the commodity by reference of name or mark of the grade.
G. According to sale:
1. Wholesale market: In such market wholesale marketing is done, Kacchha and pucca
arhatiya, wholesales are transacting the commodities.
2. Retail market: In this market retail selling takes place. The consumers are directly in
contact of retailers.
❖ Market/Marketing Channel:

A market channel is simply the path by which the commodity passes from producers to
ultimate consumer or the manner in which the products is moved from one agency to another.

The nature of the market channel for any produce may very depending upon the region, the
season of the year and the methods employed in handling. A single products may pass through
different channels. The important channels are as:

1. Producer → Primary wholesaler→ Govt. procurement → Roll →Flourmill → Fair price


shop → Consumer
2. Producer → Consumer
3. Producer → Village Bania → Kachha Arhatiya → Pucca arhatiya → Wholesaler →
Consumer
4. Producer → dealer → Wholesaler → Consumer
5. Producer → Cooperative marketing society → Consumers
6. Producer → Kaccha Arhatiya → Pucca Arhatiya → Wholesaler → Miller → Retailer →
Consumer
❖ Method Of Sale of Agricultural Produce:
1. Under cover: Under this system of sale the price is settled by brokers and arhatiyas under
the cover of the cloth
2. Open auction system: Under this system the broker invites bid for the produce and the
highest bidder is sold the produce. It is a fair system of sale.

142 Agri Coaching Chandigarh


3. Sale by private agreement: Under this system individual buyers make their offers. The
decision is conveyed by the seller to the buyers.
4. Dara sales: In this system the heaps of grain of different qualities are sold at a flat rate.
5. Close tender system: Under this system tenders are invited from the buyers. The tender
having the highest amount is accepted and commodity is given to him.
❖ Producers Surplus of Agricultural Commodities: From the marketing point of view, this
surplus is more important than the total production of commodities.
1. Marketable Surplus: The marketable surplus is that quantity of the produce which can be
made available to the non-farm population of the country. The marketable
➢ surplus is the residual left with the producers' farmers after meeting his requirements.
➢ MS = P - C (where MS = Marketable surplus P =Total production, and C = Total
requirements)
2. Marketed Surplus: Marketed surplus is that quantity of the produce which the producer
farmer actually sells in the market, irrespective of the requirements for family consumption,
farm needs and other payments.
➢ If marketed surplus is more than marketable surplus or farmer is selling against his wish,
it will be known as distress sale.
➢ Factors affecting marketable surplus: Size of holding, Production, Price of the
Commodity, Size of family, Requirement of Seed and Feed, Nature of Commodity,
Consumption Habits.
❖ Marketing Costs: The movement of products from the producers to the ultimate consumers
involves costs, taxes, and cess which are called marketing costs. These costs vary with the
channels through which a particular commodity passes through. Eg: - Cost of packing,
transport, weighment, loading, unloading, losses and spoilages.
❖ Reasons for High Marketing Costs:
1. High transportation costs
2. Consumption pattern – Bulk transport to deficit areas.
3. Lack of storage facilities.
4. Bulkiness of the produce.
5. Volume of the products handled.
6. Absence of facilities for grading.
7. Perishable nature of the produce.
8. Costly and inadequate finance.
9. Seasonal supply.
10. Unfair trade practices.
11. Business losses.
12. Production in anticipation of demand and high prices.

13. Cost of risk.
14. Sales service
❖ Factors Affecting Marketing costs
1. Perish ability
2. Losses in storage and transportation
3. Volume of the product handled
2. Volume of the More – less cost
3. Volume of the Less – more cost
4. Regularity in supply : Costless irregular in supply – cost is more
5. Packaging : Costly (depends on the type of packing)
6. Extent of adoption of grading
7. Necessity of demand creation (advertisement)
8. Bulkiness
9. Need for retailing : (more retailing – more costly)
10. Necessity of storage
11. Extent of Risk
12. Facilities extended by dealers to consumers. (Return facility, home delivery, credit
facility, entertainment)

FARM MANAGEMENT

➢ Farm management is made up of two words- field and management. “Farm” means an area
used for cultivation by a farmer or a group of farmers.
➢ The meaning of management comes to change the production plan into action and adjust the
goods used in it. So that more profit can be obtained.
➢ The study of field management helps the farmer to decide which crops to grow, how much to
produce, how to produce, at what time to produce and which crops to sell and when to buy?
etc., so that more profit can be obtained.
➢ According to Adams, “Farm management is the method of applying the principles
underlying the selection, organization and operation of a farm industry. So that as much profit
as possible can be obtained.
➢ Farm “Farm” is a specific area on which cultivation is done jointly by a farmer or a group of
farmers. "
➢ According to Tandon and Dhodhiyal, “Packet management is a branch of agricultural
economics, which studies the activities of earning and spending money by a farmer. Those
concerned with the organization, operation and marketing of the farm.
OBJECTIVES OF FARM MANAGEMENT:

1. The main objective of farm management is to reduce cost, loss and damage, inefficiency
and unemployment and to increase profit, productivity, efficiency and employment.
2. To study the resources obtained such as land, labour, capital, management, and pattern of
production.
3. To get information about the relationship between different costs and receipts in carrying
out agricultural works.
4. To know about the impact of new technology on the field.
5. Adopting crop rotation keeping in mind the size of the field, fertility, irrigation facilities etc.
6. To make proper distribution of resources among different occupations of the field.
7. To get information about the economy and economy of various industries etc.
❖ Three Main Points Arise in Farm Management:
1. How to get more production?
2. How to get more profit?
3. How to reduce the cost of production?
❖ Importance of Farm Management-

Agri Coaching Chandigarh 145


➢ Today agriculture is becoming a profitable business. One doe's agricultural work not only
for his livelihood, but also to get profit. Therefore, the farmer selects only those crops
and agricultural occupations in which maximum profit can be obtained, at present
agriculture is done on commercial basis. Therefore, it has become necessary to study
field management for the commercial and economic success of agriculture.
❖ Principles of Farm Management :-
1. Principle of Variable Proportion (Law of Diminishing Returns)
2. Principle of Factor Substitution
3. Principle of Product Substitution
4. Minimum Cost Principle
5. Principle of Comparative Advantage
6. Principle of Opportunity Cost
7. Principle of Equi-marginal Returns
❖ Economic Principles Applied to Farm Management:

The most important principle that help the farmers in making the choice and decisions to all
phases of farming are:

1. The law of diminishing returns


2. Cost analysis
3. The law of comparative advantages
4. The law of equi-marginal returns
5. The law of substitution
6. Principle of opportunity cost
7. Principle of combining enterprises
➢ Farm management is a science which deals with the proper combination and operation of
production factors including land, labour and capital and the choice of crop and livestock
enterprises to bring about a maximum and continuous return to the most elementary operation
units of farming. Farm management is concerned with decision making.
➢ The main decisions are:
1. What to produce: It decides which products to produce. It shows the product-product
relationship.
2. How to produce: It relates to choosing the most effective method of producing a given
quantity of a particular product. It shows the factor-factor relationship.
3. How much to produce. It relates to the problems in converting the several farm
resources into the final farm product. It shows the factor-prodct relationship
4. Time relationship: It shows relationship between the time that farmer makes investment
of capital and that later date when this investment returns the physical production

146 Agri Coaching Chandigarh


➢ These four relationships are based on physical or technical facts but require price and
cost information in order to make economic interpretations.
❖ Production and Factor of Production: -
➢ Production It is the process by which some goods and services, called inputs, are
converted into other goods and services, called outputs, which create utility.
❖ Production factors
➢ There are the four main factors of production:
(i) Land :- It is a main natural resource that generates income. It represents those natural
resources which are scarce and profitable.

➢ Features of Land:-
✓ This It is a gift of nature and is stable in quantity.
✓ This is Permanent and not destroyed.
✓ This is immovable and stable.
✓ Geographical supply of earth cannot be increased, but economic supply can be
increased. (By making the land denser and more used.)
✓ There is considerable variation in the composition and fertility of Earth.
(ii) Labour :- When Any work is done by hands or by mind for the purpose of money, which
is called labor.

➢ Features of Labour
✓ Without help of labour Production cannot be done from the land.
✓ Labour cannot be separated from the worker.
✓ short term Labor supply cannot be adjusted with demand.
✓ Changes affect labor cost and labor supply.
✓ Labour is an active factor.
(iii) Capital :- The money which is used to create future wealth is called capital. Capital is not
the real factor of production this is man made factor. All capital may necessarily be
money, but not all money may necessarily be capital. All Capital is money, but not all
money can be capital.

➢ Features of capital:-
✓ Capital is a productive factor.
✓ This generates income
✓ Capital is a deactivating factor.

Agri Coaching Chandigarh 147


(iv) Organization :- Organization The main role of a business is to establish good relations
and coordination with other companies.

➢ Rewards for the Factors of Distribution


✓ Reward of Land - rent
✓ Reward of Labour - wage
✓ Reward of capital - Interest
✓ Reward of business - Benefit
❖ Some Basic Concepts:
➢ Farm: Piece of land where livestock enterprises are taken under single management
system and has specific boundaries.
➢ Agriculture holding: Total area of land owned by individual or joint family whether
cultivated by family or rented out.
➢ Operational holding: Total area held under single management for the purpose of
cultivation. It excludes any land leased out to another person.
➢ Family holding: Farm having gross income (Rs. 1600), net income (Rs. 1200).
➢ Optimum holding: (3 × 𝑓𝑎𝑚𝑖𝑙𝑦 ℎ𝑜𝑙𝑑𝑖𝑛𝑔) →
𝑚𝑎𝑥𝑖𝑚𝑢𝑚 𝑠𝑖𝑧𝑒 𝑜𝑓 ℎ𝑜𝑙𝑑𝑖𝑛𝑔 𝑎𝑛𝑑 𝑓𝑎𝑚𝑖𝑙𝑦 𝑠ℎ𝑜𝑢𝑙𝑑 𝑝𝑜𝑠𝑒𝑠𝑠.
➢ Economic holding: Which provide a reasonable standard of living + give full
employment.
➢ Marginal farmer: Having land less than 1 ha or 2.5 acre.
➢ Small farmer: Having land between 1 ha to 2 ha.
➢ Fixed resources: Resources which remain unchanged irrespective of level of production
are called fixed resources (Exist in short run). E.g.: Land building.
➢ Variable resources: Resources which change with level of production are called variable
resources, Higher the level of production, greater the use of resources and vice-versa.
E.g.: Seed fertilizers.
➢ Flow resources: Resources which cannot be stored and should be used as and when they
are available.
➢ Stock resources: Resources which can be stored, when they are not used in one
production period. E.g.: Seeds, fertilizers, feed etc.
➢ Cost of cultivation: Expenditure incurred on all inputs and input services in raising a
crop on a unit area written as wst in Rs/ha.
➢ Cost of production is expenditure incurred on providing a unit quantity of output is called
wst of production written as Rs/tonne or Rs/quintal.

1. The law of diminishing returns:

➢ It is physical law of fundamental importance in organizing and operating the farm


business. It is an important guiding factor in farming to decide the level at which a farmer
can increase his output.
➢ It is practical experience of every farmer that after a certain stage in cultivation, the
application of successive does of labour and capital to a given area of land does not bring
about as much return as the previous does.
➢ Additional dose of labour and capital and labour applied to the cultivation of land causes
in general, a less than proportionate increase in the amount produce unless in happens to
coincide with an improvement in the arts of agriculture''

2. Cost analysis:

➢ This principle is of great importance in making decisions of farm business. Cost in


general, refers to the expenses incurred on productive services and physical productivities
are guided by the cost of various input factors, mainly costs are of two types:
(i) Fixed cost: Fixed costs present farming expenses of an overhead nature and donot
change with the output, e.g., interest on fixed capital, depreciation, revenue etc.
(ii) Variable costs: it varies with the level of output. It includes changes of hired human
labour, seed, manure and fertilizer, irrigation, insecticides and pesticides etc. These are
seven costs of production
(a) Total variable cost (TVC): it is obtained by multiplying the amount of variable input
by the price per unit of output.
(b) Average variable cost (AVC): it is computed by dividing total variable cost by the
amount of output. AVC varies with the level of production.
Average variable cost is:
AVC = TVC/Outpur
(c) Marginal cost (MC): MC is the change in total cost as related to change in output. It is
calculated by dividing the change in total cost by the corresponding change in output,
i.e., ∆ TC/ ∆ Y. The marginal or added cost of each unit of output is important in
determining how for we should push production and how much of the various
resources we should use.
(d) Total fixed cost: total fixed cost shows the some of expenditures which will be
incurred irrespective of the output.
(e) Average fixed cost: It is obtained by dividing total fixed costs by the amount output.
As the output increase the average fixed costs decreases.
AFC = TFC/Output

Agri Coaching Chandigarh 149


(f) Total cost: It is the sum of total fixed cost and total variable cost.
TC = TFC + TVC
(g) Average total costs: It is worked out by dividing TC by output.
ATC = TC/Output

3. The law of comparative advantage:

➢ The law of comparative advantage helps to explain regional specialization. Farmers tend
to produce those items which give more income at a lowest relative cost.
➢ With the income, they buy the items needed for production and for living which are
produced at lowest relative cost in other areas.
➢ In short, specialised, and diversified farming are based on this principle. For example,
sugarcane cultivation near sugar mill, vegetable cultivation near cities, rearing of sheep
and goats in hilly areas will give more profit tha n the other places.

4. The law of Equi marginal Returns:

➢ Equi-means 'equal' marginal means additional or incremental. The law states that profit
will be greatest if each unit of labour, capital and land is used where it adds the most to
the return.

5. The law of substitution:

➢ The principle which helps selection from a number of alternatives is called law of
substitution. According to this law the least cost combination of inputs or practices is
obtained when the inputs or practices replaced is equal to the value of the input or the
practice added.
➢ Procedure for finding out least cost combination:
(i) Computation of marginal rate of substitution (MRS) by dividing the number of units of
the replaced input (X1) by the number of units of added inputs (X2).
𝑛𝑜.𝑜𝑓 𝑢𝑛𝑖𝑡𝑠 𝑜𝑓 𝑟𝑒𝑝𝑙𝑎𝑐𝑒𝑑 𝑖𝑛𝑝𝑢𝑡 (x1 )
Substitution ratio: =
𝑁𝑜.𝑜𝑓 𝑢𝑛𝑖𝑡𝑠 𝑜𝑓 𝑎𝑑𝑑𝑒𝑑 𝑖𝑛𝑝𝑢𝑡 (x2 )
Where X1 is replaced by X2
(ii) Computation of price ratio by dividing the price of added input (Px2) by the price of the
replaced input (Px1)
𝑃𝑟𝑖𝑐𝑒 𝑜𝑓 𝑎𝑑𝑑𝑒𝑑 𝑖𝑛𝑝𝑢𝑡 (PX2 )
Price Ratio =
𝑃𝑟𝑖𝑐𝑒 𝑜𝑓 𝑟𝑒𝑝𝑙𝑎𝑐𝑒𝑑 𝑢𝑛𝑖𝑡 (PX1 )
(iii) Calculation of least cost combination by equating (MRS):
∆X1 ∆X2
MRS = =
∆X2 ∆X1

150 Agri Coaching Chandigarh


➢ Least cost is realized at the point where the ratio of the input prices is inversely equal to
their marginal rate of substitution.
➢ It is substitution ratio is greater than the price ratio, then we can lower costs by using
more of the added input.
➢ If the substitution ratio is less than the price ratio then the cost can be reduced by using
resource used in its most profitable alternative use.

6. Principle of combining Enterprises:

➢ An enterprises in farm business is defined as the production of a single crop or kind of


livestock. Generally, farmers take more than one enterprise on their farms.
➢ The main aim of the farming is to get the maximum profit with minimum expenditure by
combining enterprise.
➢ The combination of enterprises on a farm is influenced by the relationship that exists
between the enterprises.
➢ The enterprises can have any one of the relationships explained below:
(i) Independent enterprises: These enterprises do not have direct bearing on each other.
There is no effect on the other enterprises when level of one enterprises is influenced or
decreased.
(ii) Competitive enterprises: Competitive enterprises are those enterprises which compete
each other for the resources. Farmers have limited resources and therefore, all crop and
livestock enterprises become competitive at some point. An increase in the output of
one enterprise results in a decrease in the output of the other enterprises. Maize, bajra,
paddy and sugarcane etc. in the same season compete with each other for resources.
(iii) Supplementary enterprises: Supplementary enterprises are those which do not
compete for resources but help in increase income of the farmer. A small poultry
enterprise is supplementary to other enterprise of the farm. A supplementary enterprise
becomes competitive if it is expanded too far.
(iv) Complementary enterprises: Complementary enterprises are those enterprises which
help each other in production and do not compete for resources. For example, if jowar is
grown after berseem crop the yield of jowar increases because berseem fixes
atmospheric nitrogen in the soil.
❖ Time Comparison Principle :-
➢ Compounding: It is calculating future value of the money held by a person at a present (by
including rate of interest in it).
➢ Discounting: It is calculating present value of money if future sum of money will be given.

Agri Coaching Chandigarh 151


➢ Principle of Opportunity Cost:- The cost of the next best alternative foregone is called as
Opportunity cost.
➢ Principle of Equimarginal Returns :- the limited resources should be allocated among
alternative uses in such a way that the marginal value of the product of the last unit of the
resource is equal in all uses.
➢ Minimum Loss Principle ( Same as Cost Analysis in Microeconomics)
❖ Types of Farming :-
➢ Types of Farming - When the classification of farming is done on the basis of use of land,
size of farm, use of machines and machines, production of animals and crops, etc., then it is
called type of farming, such as specialized farming, dry farming.
➢ According to Dr. Ross, "The type of farming refers to the use of land, the production and
growth of crops and livestock, and the manner of agricultural activities."
✓ Specialised Farming
✓ Diversified Farming
✓ Mixed farming
✓ Dry Farming
✓ Ranching
➢ Specialized Farming: Special farming means those holdings which get at least 50% of their
income from any one enterprise or crop.
➢ In India, this type of cultivation is done only in the form of plantation in Assam or Nilgiri
areas.
➢ Diversified Farming: In this there are many occupations of farmer's income. The farmer
gets only a small part of his income from any one crop, less than 50%. Thus, there is no
main source of income. Everyone gets some income. Diversified farming is also called
general farming.
❖ The Advantages of Multivariate Farming Are: -
1. Farmers remain independent.
2. The income of the farmer remains constant.
3. Animals, instruments, tools, land, etc., are all fully utilized.
4. To maintain soil fertility.
5. The family members continue to get work throughout the year.
6. The standard of living of the farmer is improves.

❖ Systems of Farming :-
➢ Peasant Farming
➢ Co-Operative Farming
➢ Capitalistic Farming
➢ Collective Farming (Russia and China)
➢ State Farming
❖ Depreciation
➢ The decline in the value of asset due to usage, accidental damage and time obsolescence.
➢ Junk Value :- The remaining value of an asset when it is completely destroyed. Or the
value at the end of useful life.
➢ Book Value :- The value of an asset which is obtained by deducting the annual
depreciation from the Original Cost every year.
❖ Methods of Depreciation
➢ Straight Line Method
✓ Amount of Depreciation = (Original Cost of the Asset- Junk Value) / Useful life of
asset.
➢ Diminishing Balance Method
✓ The method assumes varying rates odf use of asset, year after year.
✓ Amount of depreciation = (Book value of asset) X R

Agri Coaching Chandigarh 153


✓ Where R = Rate of Interest
➢ Sum of the years digit method
✓ Annual amt. of depreciation =
✓ (Original Cost- Junk Value) X Remaining years of useful life
✓ Sum of the Digits from one through useful life
➢ Annual Revaluation Method
✓ As the name indicates, the asset is revalued every year.
✓ More specifically the value of an asset is calculated at the beginning and end of the
year.
✓ Generally, this method is used for land and livestock in agriculture.
❖ Farm Planning and Budgeting:
➢ Farm plan is the complete scheme for the operation and organization of a farm business.
Farm planning is a process or technique for making plans about optimum choice and
combination of farm enterprises.
➢ Farm planning serves the basis of farm budgeting, and a farm plan can be prepared without
a budget.
❖ Factors effecting farm planning:
1. Inventory of farm resources: The inventory of farm resources should be taken at the
beginning and the end of the year. It includes as appraisal of land, labour, capital (building,
livestock, machinery, and layout) and management.
2. Land: The appraisal of the land will involve a determination of quality and quantity of the
various types of soil. The location of land, types, irrigation facilities and fertility status are
factors to be considered the value of land.
3. Labour: An examination of human and bullock labour programme will lead to a much
effective organization of farm business.
4. Capital: It plays an important role in the farming business. Capital includes building,
livestock, implement and machines and layout.
5. Management: It determines the success of business. It is a mental process and occurs
when a farmer:
(i) observes and secures ideas,
(ii) analyses his observations and ideas,
(iii) makes decision on the basis of his analysis,
(iv) acts on the basis of his decisions and
(v) accepts the responsibility and consequences of his decisions.
❖ Partial Budgeting:

154 Agri Coaching Chandigarh


➢ It consists of a detailed description of the income and expenditure of an enterprise, a few
enterprises or to a part of total farm.
➢ Symbolically it can be expressed as:

R = Qy1 Py1 – [X1PX1 = X2PX2 + ………….. XnPn] – F.C.

Where R = Net return

Qy1 = Quantity of output

Py1 = Price of output

XnPn = Inputs

Px = Price of inputs

F.C. = Fixed cost

❖ Advantages of Partial Budgeting:


1. They are comparatively simple, quick and easy.
2. They may provide a clear indication of the profitability of a particular enterprise.
3. They provide a clear plant for utilizing a particular resource.
4. They may serve as an efficient means of adopting total budgets without compeletely
reworking them.
5. By concentrating attention of a single enterprises or resource they are likely to result in
fuller treatment of related problems.
6. They can be used to compare costs and returns associated with different practices such as of
bullocks or tractor power.
❖ Complete Budgeting:
➢ It may be defined as detailed statement of the estimate of cost and returns of a farm as a
complete unit.
➢ Symbolically it can be expressed as:
R = [Qy1P1+Qy2P2+Qy3P3 ……… QnPn] – [X1Px1+X2Px2+ ……….XnPn] – F.C.
Were,
R = Net return of output
Qs = Quantity of output
Ys = Different enterprises

Agri Coaching Chandigarh 155


Ps = Price of output
Xn = Inputs
Pxn = Price of input

❖ Advantages:
1. It consists of the farm as a unit and all resources and enterprisses simultaneouly.
2. It may allow for substitution relationship between resources.
3. It allows for the complementary, supplementary, or competitive relationship between
enterprises.
4. It drawn attention to the multitude of factors affecting farm earning.
5. It permits comparison of the probable total earning of the same farm with different
combination of enterprises.
6. It avoids the necessity of allocating joint cost between enterprises.
❖ Steps Involved in The Process of Budgeting:
7. Making the inventory of farm resources (land, farm size, building, livestock, dead stock
etc.)
8. Etimation of capital position of the farmer and determination of his credit needs.
9. Assessment of the availability and source of credit meet his credit requirement.
10. Determination of availability of family and hired human labour.
11. Working out cost and return in relation to the present operation so as to set objectives for
future plans.
12. Drawing of alternate plans and settlement of the final plan in view of limitation.
❖ Use of farm planning and budgeting:
1. It is helpful in determination of needed adjustments as a yardstick for agricultural credit.
2. It is helpful in formulation and appraisal of development projects.
3. It provides road to farmer's security.
4. It provides basis for calculation of agricultural income of the whole country.
