AGRICULTURE
Agriculture is a combination of two words i.e. Agri and culture. Agri means farming
and culture means practice; it means practice of farming is called agriculture.
Agriculture is the process by which food crops and other goods are produce, including
Wheat, Rice, Sugarcane, Maize along with Cotton etc.
SUBSISTENCE FARMING
Subsistence farming means growing of crops mainly for the people who work on them.
Surplus is sold in the local village market.
Most of the farmers have to supplement their income from othr sources e.g. carpenter,
blacksmith, cobbler.

NATURAL INPUTS
Agricultural requirements provided by nature e.g. Land, Soil, Climate.
FLAT LAND
Use of machines.
Crops grow at equal height, easy to harvest
Distribution of water equally
Less soil erosion
Less drainage
Easy to cultivate
Provision of canal irrigation
SOIL
Soil is the material in which the roots of the plant are embedded.
A soil suitable for growth contains sufficient minerals for crop growth and also has
sufficient pore spacing.
4
Pore spacing is important as it controls the amount of air and water available for plant
roots.
Too little spacing (clayey) soil means that it will contain less air and more water,
thus won’t support plant growth
On the contrary a sandy soil will allow air but will also allow a lot of water to infiltrate
into the subsoil. This water may also take down with its fertilizers and other natural
minerals (which are wasted as roots did not have time to absorb them)
The best soil is loamy soil, which contains sufficient pore spaces (to allow for sufficient
air and moisture). Spaces aren’t too big; so, the soil does retain nutrients, which are not
leached into the soil
The soil must be deep and must contain nitrates and phosphates; which are required
for crop growth
Alluvial soil contains nutrients, retains water, retains fertilizers. This type of soil can
be drained easily
CLIMATE
Every crop has its own distinct climatic requirements. This includes rainfall, humidity,
temperature, amount of sunlight etc.
In Pakistan, these requirements basically fall into two groups, Kharif and Rabi.
Sunshine
Photosynthesis

Disadvantages
SEEDS
A desi variety of seeds produces lower yields as compared to a high yielding variety of
seeds.
But it must be noted that only desi varieties are adapted to the local climatic conditions.
Therefore, to achieve high yields in an adverse climate a hybrid of the two varieties is
required
Advantages of Desi
Cheap
Less Chemical Fertilizer required if compared with HYV
Locally available
Advantages of HYV
Increases yields

PROCESSES
A series of things that are done in order to achieve a particular result.
Ploughing
A large piece of farming equipment with one or several blades pulled by a tractor or
animal. It is used for digging and turning over soil specially before seeds are planted.
Sowing
Spreading seeds in or on the ground with machine or by hands.
Irrigation
To supply water to an area of land through tube well / channels so that crops will grow.
Fertilizing
Weeding
Cutting of wild plants growing where they are not wanted especially among crops.
Threshing
To separate grains of wheat or rice from the chaff.
Harvesting
Cutting the crop
WHEAT

Rabi crop
Uses
By Products
Chaff, used for feed and mix it with mud to make storage hut
Method Of Cultivation
In oct-dec after ploughing the field, wheat seeds are sown directly into the ground
Most of the farmers irrigate land twice.
First irrigation, one month after sowing
Second irrigation one month before harvesting
Harvested after three months

BARANI FARMING
It is practiced in areas like the Potowar Plateau which have low amounts of seasonal
rainfall.
Important crops grown are wheat, maize, millet etc all which require low amounts
of water and sunlight
When the rains arrive or are about to arrive, the land is ploughed so it becomes
soft.
Immediately after the rain, the seeds are sown and the periodic cycle of sunny
weather in between light rainy days continues till the harvest.
Within the growing period hoeing is done (to remove weeds), if pesticides and fertilizers
are available then they are added otherwise cow dung is used.
Lastly the harvest season must be sunny and dry.

RICE
Type
Kharif
Uses
Used as food
Exported
By Products
Rice husks are used for making cardboards or covering roofs of houses after mixing it
with mud
For livestock
Method Of Cultivation
The tractor pulls a plough in march. Each time he ploughs, he goes in a different
direction, so that soil is well broken up.
If the farmer cannot afford to hire tractor, he uses a bullocks to pull a plough at
the right depth in the soil.
While land is being prepared, rice seeds are sown in the nursery in the corner of
the field.
When seedlings are about 30 cm tall, they are ready to be transplanted.
In may, farmers usually employ some labour for transplanting.
Bundles of rice seedling are carried from nursery to prepared fields.
Prepared fields have now been flooded to a depth of 25 cm, ready for
transplanting the seedlings
It is skilled work because seedling will float away if they are not planted properly.
Rice crops are protected from birds
Fertilizers is scattered on the field
Insecticide is also scattered on the field
In September, rice is ripe and ready for harvesting
Water is drained off
Sickle is used to cut the crop
Rice is then tied in bundles and carried to be threshed manually.

APRICOTS
Apricots are grown mainly in areas of mid-northern Balochistan.
Pakistan is the 4th largest producer of Apricots.
The apricots need to fulfil chilling units, meaning that they must be exposed to cold for
a certain period of time.
Winters must be cold (but not colder than -30°C) to allow for proper dormancy.
Dry weather must exist at the time of maturity/harvest.
It is important that there should be no sudden and dramatic change in
temperatures in spring which kills the flowers.
Apricots grown in well drained soils with PH around 6.5
MANGOES
Mango requires a wet hot summer season with rainfall around 250mm.
This needs to be followed by a long dry winter.
Dry winter means that the plant is less susceptible to attacks by fungus etc.
It needs deep well drained loamy soil.
Mangoes are grown in southeastern Punjab and eastern Sindh.
27
TOBACCO
Tobacco plants are usually first grown in nurseries etc and then transplanted in the fields
when the risk of frost has passed.
They need light rainfall early on, followed by a period of bright sunshine with rains in
between, followed by a dry period at harvest
Tobacco is grown in central parts of Punjab, northern Balochistan and central parts of
Khyber-Pakhtunkhwa
PULSES
Pulses require high temperatures but are highly susceptible to frost.
They can also tolerate high rainfall provided it doesn’t come at time of pollination
etc.
Also the soil must not be waterlogged or saline. Pulses can be grown on sandy, loamy etc
soils
Pulses are grown in eastern and western Sindh, along with north eastern Punjab
28
MILLET
Millet requires moderate rainfall and is sensitive to frost.
It will not tolerate waterlogged soils or harsh drought.
They are grown in southeastern and northwestern Punjab, western Sindh, and
central and southeastern Balochistan
DATES
Dates are grown in parts of Balochistan and in parts of Tharparkar desert (southern
Punjab and eastern Sindh).
It needs long hot summers with high day and night temperatures.
It can tolerate fluctuations in temperature whether cold or hot.
Mild winters and a dry sunny time for harvest is also required.
They can grow in salty soils but they must be well drained
APPLES
Apples are solely grown in northern Balochistan.
They have the highest requirement of chilling units in fruits.
Winters must be cold to allow for proper dormancy.
These must be followed by rains during the growing season.
29
CITRUS FRUITS
They grow in tropical or subtropical climate with hot summers and moderate rainfall.
They are also sensitive to frost and strong winds.
Most of the production is from Punjab including its central but mostly southern
parts.
Some citrus production also occurs in eastern parts of Sindh
BANANAS
Bananas are grown exclusively in southern Sindh.
They require a hot dry season lasting for around 2-3 months, with a mean rainfall of
around 10 cm.
Bananas are very sensitive to frosts, which can suspend maturity or even kill the plant.
They are also very vulnerable to strong winds, which damage the fruit etc.
They require well drained alluvial soils
30
OILSEEDS
Oilseeds usually require average temperatures varying from 20-30°C.
It must also be noted that high temperatures can hamper or delay growth and that
frost kills the plants.
Oilseeds are tolerant to drought for some periods and require well drained deep
alluvial soils
They are grown in southern parts of Punjab and eastern parts of Sindh, along with some
northern parts of Punjab.
MAIZE
Maize needs a hot bright growing season to flourish.
It is very intolerant to frost and needs moderate rainfall well distributed throughout
growth.
It also needs well drained deep alluvial soils
It is grown in central Punjab and central parts of Khyber-Pakhtunkhwa

LIVESTOCK FARMING
This type of farming (also known as pastoral farming) is concerned with rearing of
animals, whose products are then sold.
NOMADIC FARMING
Nomads are the people who move from one place to another place along with their
livestock in search of water and pasture.
Once they find these resources and settle over there and utilize their resources
They move to another place so that’s why they keep on moving for the search of new
pastures.
They hardly return to the old pastures unless rainfall takes place for new pastures to
grow.
The area in which they graze have very poor pastures because of extreme arid
conditions.
They keep sheep, camels and goats because they can survive in arid conditions and can
survive in poor pastures as they can nibble the thin glass.

Rugged landscape.
Population density is least so plenty of land is available.
34
TRANSHUMANCE
It is seasonal migration along with the livestock especially in winters from highland
areas to the valley.
When the summer approaches they move back to the high land pastures, but below
snow line.
In winter high land pastures are covered with snow and water sources also freezes so
that’s why they move to valley where temperature are suitable for them to survive
and water, pastures are available.
Sometimes they move to village market for selling their surplus such as animals,
wools, skin and milk.
In summer they move back to high land pastures below snowline because in summer
rich pastures grow as snow and glaciers melt so therefore water is available.
They are mainly found in N.mountain and western highlands
From Himalayas they migrate towards to Kashmir valley.
From Hindukush to Chitral and Swat valley.
They keep sheep, goat, cattle, yak as these animals can adapt in highland climate and
mountainious topography.

POULTRY FARMING
Poultry farming is the practice of raising poultry, such as chickens, turkeys, ducks, and
geese, as a subcategory of animal husbandry, for the purpose of farming meat or eggs
for food.
In Pakistan, most of poultry farming consists of chicken.
Poultry farms are mostly found around dense centers of population (Karachi, Quetta,
and Lahore) and cooler areas (Murree, Abbottabad).
Nearness to population centers reduces cost of transportation and cooler areas are
preferred for optimal growth of chickens.
First the poultry farm building is cleaned properly, disinfectant is applied and the
building is fumigated.
Maize is used as food, when the chicks arrive, they are given antibiotics in their food
for 3-7 days.
The temperature of the building is maintained between 32 and 37 degrees
Celsius.
The chickens are put in cages so their eggs and wastes can be easily removed etc.
After around 4-8 weeks the chickens can be slaughtered for their meat
37
38
BUFFALOES
Buffaloes are found mostly in canal fed areas of Pakistan, especially the doab
between Ravi and Sutlej.
Nilli-Ravi breed is found in Punjab, which is known for its high milk
production.
In Sindh, Kundi breed is found along both banks of Indus but mostly in Northern
and central Sindh.
Other breeds are found in areas of Khyber-Pakhtunkhwa
Presence of water is very important as this animal needs to cool itself by smearing
mud on its body.
Water is also used for drinking and for cleaning the farm etc.
A lot of fodder is also required (which becomes expensive to buy in non- agricultural
areas) and thus buffaloes are not found in Balochistan as this would be too
uneconomical.
There are less urban areas there and thus les demand for beef.
Buffaloes are considered to be black gold of Pakistan because the milk they produce
has a higher fat content than that of cows and goats etc.
At present, buffaloes provide almost 70% of the milk produced in Pakistan.
Also, their meat is white and desirable due to the low cholesterol level as compared
to cow’s meat
However, it must be noted that still there is ample room for improvement.
Pakistan is the 2nd largest buffalo milk producer in the world after India.
Also, Pakistan has one of the best breeds for producing milk (like Nilli and Ravi) but due
to mismanagement, inefficient marketing system, old livestock technique, exposure to
heat, shortage of fodder and late age of maturity mean that this potential is yet to be
exploited
39
CATTLES
Important cattle breeds are Red Sindhi and Sahiwali, which are
internationally recognized for their milk production.
Another important Breeds are bhagnari (Imp for draft power found in Punjab
and sindh), Dhani (Imp for draft power found in N.Areas)
Cattle are spread in Northern, central and Southern Punjab.
In Sindh mainly in areas of Tharparkar desert.
In Balochistan they are found in district of Hab and in Northcentral parts of Khyber-
Pakhtunkhwa
The yield of dairy animals in Pakistan is around 1/5 to 1/7 as to what yields are
achieved in Europe and United States of America.
If our yields can be improved this can save us from import of milk and related
products, which costs around 20 million dollars annually.
40
GOATS
Goats have a much wider distribution than sheep in Pakistan.
They are found in almost whole of Punjab, Eastern and Southern Sindh, Makran coast
and central Balochistan and districts of Peshawar and Mardan in Khyber-Pakhtunkhwa.
Goats are also very adaptable like sheep but since their meat and milk is preferred
over sheep; to satisfy this demand they are reared in larger numbers as compared
to sheep
SHEEP
Sheep are mostly found in rugged areas of Northern Balochistan, Gilgit- Baltistan,
Khyber-Pakhtunkhwa and parts of Southern Punjab.
Sheep can survive both hot and cold seasons, and feed on shrubs and grasses.
These adaptabilities make them vital for people living in these areas for meat, milk,
wool, bones etc
PROBLEMS OF LIVESTOCK
Few veterinary facilities
Lack of grazing grounds
Expensive and difficult to keep in urban areas
43
IMPROVEMENT IN LIVESTOCK
Capital, investment, loan subsides
Selective, cross breeding
Better feed
More grazing land
Control of disease
Vaccination
Better hygiene, care
Mechanization.
