UNIT 1 THE MEANING AND IMPORTANCE OF FARM RECORDS
MEANING OF FARM RECORDS
Farm records are written information that farmers keep on different activities carried out on a farm.

THE IMPORTANCE OF KEEPING FARM RECORDS

 making important decisions

 budgeting and planning

 calculating profit or loss

 selecting livestock

 obtaining loans from money lending institutions

UNIT 2 PHYSICAL FARM RECORDS

Physical farm records are all farm records dealing with production.

EXAMPLES OF PHYSICAL FARM RECORDS

 field operations records

 crop records

 labour records

 layers records

 milk production records

 inventory records (record of items on a farm)

1. FIELD OPERATION RECORDS

A field operation record is a record of daily activities done by a farmer from land preparation to
harvesting. This record shows inputs used on the crops such as type and amount of seed,
fertilizers, chemicals and labour used.

2. CROP RECORD
A crop record shows the crop, plot number, plot size, type and amount of seed used, type and
amount of fertilizer or manure and amount of insecticides used.

3. A YIELD RECORD
A yield crop shows the amount of yield harvested for each crop grown on the farm. The amount
is recorded in kilograms.
 4. A LABOUR RECORD
A labour record shows crop, plot number, plot size, activity and work done (man days). Labour is
work done by human beings measured in man days.

5. A LAYERS RECORD
A layers record shows the date, the number of hens laying, the number of eggs collected daily
and the amount of feed used daily.

UNIT 3 FINANCIAL FARM RECORDS

MEANING OF FINANCIAL FARM RECORDS

Financial records are records dealing with money on a farm.

OR

Financial farm records are all records of accounts that show income and expenditure.

EXAMPLES OF FINANCIAL FARM RECORDS

 sales records

 expenditure records

 production records

In financial farm records, there are two main columns of income on one side and expenditure on the
other.

The difference between the total income and total expenditures gives the profit or loss of a particular
farming activity.
Any produce from the farm eaten or used at home should be valued at current market price.

This should be recorded under sales and receipts because the farmer would have sold such produce for
income.

UNIT 4 SOURCES AND IMPORTANCE OF WATER

SOURCES OF WATER

 Rivers

 Dams

 Lakes

 Streams

 Boreholes

 wells

However, all these sources depend on rainfall.

THE IMPORTANCE OF WATER TO CROPS

 Seed germination

 Irrigation of crops

 Pollination of flowers

 Making plant food

 Transportation of farm inputs and produce

THE IMPORTANCE OF WATER TO LIVESTOCK

 For drinking

 Fish farming

 Washing utensils

 Dip tanks – chemicals at dip tanks are mixed with water to make dip wash or dip solution. This
helps to kill external parasites in farm animals

WAYS OF IMPROVING AVAILABILITY OF WATER

 Avoiding cutting down trees carelessly around sources of water

 Construction of dams and boreholes

  Provision of piped water

WAYS OF IMPROVING THE QUALITY OF WATER

 Avoiding putting wastes in rivers

 Adding chlorine to dirty water

UNIT 5 IRRIGATION

MEANING OF THE TERM ‘IRRIGATION’

Irrigation means supplying water onto a field to enable crops grow.

IMPORTANCE OF IRRIGATION

 Avoiding risks of hunger

 Helps farmers to grow crops several times a year

METHODS OF IRRIGATION

 Sprinkler irrigation

 Drip irrigation

 Basin irrigation

 Flooding irrigation

SPRINKLER IRRIGATION

Water is supplied to crops through pipes which have nozzles at one end to spray the water.
the sprinkler irrigation method

DRIP IRRIGATION
This is also known as trickle irrigation. Water is led through plastic pipes which are laid on the ground.
The pipes have small holes through which water comes out. The spacing between the holes is
determined by the distance between the planting stations of the crops. Water intake by the soil is
controlled.
the drip irrigation method

BASIN IRRIGATION
Water is led to basins through furrows. This method is good for fruit trees.

the basin irrigation method

FLOODING IRRIGATION
Water is supplied in a plot through flooding. This method is common in rice fields. The land should be
flat.

UNIT 6 SOIL COMPOSITION

The term ‘soil’ means the loose material covering the surface of earth.

THE COMPOSITION OF SOIL

Soil is made up of different materials.

These include the following:

  Inorganic matter

 Organic matter

 Soil water

 Soil air

1. INORGANIC MATTER

 This is made up of sand, silt and clay particles. This forma the largest part of the soil.

2. ORGANIC MATTER

 This is made up of living, decaying and decayed plant and animal parts. The decayed matter is
called humus.

3. SOIL WATER

 This is soil moisture.

4. SOIL AIR

 This is air trapped between the soil particles.

UNIT 7 THE IMPORTANCE OF SOIL THE IMPORTANCE OF SOIL TO CROPS

 Holds plants

 Supplies water to plants

 Provides mineral salts to plants

 Provides air

 It is home of soil organisms

A farming calendar is a list of activities to be done in each month of the year for a given crop.

The table below shows the forming calendar for groundnuts

Month Activities
September Clearing land
October Ridging
November Planting
December Planting and weeding
Febuary Banking and hand wedding
March maturity
April Lifting
May Drying
June Stripping and storage
July Shelling
August Selling groundnuts
THE IMPORTANCE OF A FARMING CALENDAR

 It is a source of farm record

 It guides the farmer to carry out all farming operations or activities at the
appropriate time

UNIT 12 LAND PREPARATION FOR GROUNDNUTS AND CASSAVA

Land preparation for growing field crops such as groundnuts and cassava should be done soon after
harvesting the preceding crop.
This is what is known by early land preparation.

REASONS FOR EARLY LAND PREPARATION

 It is easy to till the ground

 It promotes the decomposition of crop residues which improves soil fertility

 It enables the farmer to plant with the first rains

ACTIVITIES INVOLVED IN LAND PREPARATION

 Site selection

 Clearing land

 Ploughing the land

 Ridging

 Making box ridges

UNIT 13 SEED SELECTION IN GROUNDNUTS AND CASSAVA

In Malawi, most farmers buy seeds from shops.

However some farmers select seeds or planting materials from the previous crop.

FACTORS TO CONSIDER WHEN SELECTING GOOD SEEDS OR PLANTING MATERIALS

 Ability to germinate

 Large size

 Wholeness (unbroken or undamaged)

 Free from diseases

 Purity (not mixed with any other materials)

 Maturity

 Suitable variety for climate of the area

UNIT 14 PLANTING GROUNDNUTS AND CASSAVA

Like any other field crops, groundnuts and cassava must be planted at the right time, spacing, seed rate
and depth.

Groundnuts
In Malawi, groundnuts are planted with the first or soaking rains of between 25mm and 30mm.

It is usually between October and November in the southern region and November and December in the
central and northern regions.
The spacing between ridges and planting stations for groundnuts depends on the variety.

VARIETIES, SEED RATE AND SPACING IN GROUNDNUTS

Seed rate (kg/ha) Spacing (cm) Planting depth

Variety

Chalimbana 110 75 x 15 x 1 seed 5-7cm

Chitembana 120 75 x 15 x 1 seed 5-7cm

CG7 110 75 x 15 x 1 seed 5-7cm

Nsinjiro 100 75 x 15 x 1 seed 5-7cm

Manipintar 80 75 x 15 x 1 seed 5-7cm

Mawanga 80 75 x 15 x 1 seed 5-7cm

RG1 80 75 x 15 x 1 seed 5-7cm

Malimba 45 75 x 10 x 1 seed 5-7cm

Kakoma 60 75 x 10 x 1 seed 5-7cm

Baka 60 75 x 10 x 1 seed 5-7cm

Cassava
Cassava is also planted with the first soaking rains in all the regions in Malawi.

It is recommended to plant cassava on ridges spaced at 90 centimetres apart and 90 centimetres

between planting stations where it would be processed into Kandowole.
For the tubers to be sold fresh at the market, spacing of 90 centimetres between ridges and 45
centimetres between planting stations is used.
Cassava planting materials must be obtained from a middle portion of a well matured plant. Cassava
cuttings should be 25 to 30 centimetres long with at least two nodes.
Cuttings should be planted at an angle and two thirds of the cuttings should be planted into the soil. This
prevents water from settling down on the cut edges which can cause rotting of the cutting.

The improved varieties of cassava include silira, maunjiri and mkondezi.

There are also local varieties that are grown in Malawi like Manyokola (mbundumali), Gomani and
Chitembwere.

Groundnut seed and cassava planting materials that have not germinated or sprouted have to be
replaced immediately so that they can almost grow together with the seeds or planting materials of the
first planting.
Replanting where germination failed is called 'supplying'.

Supplying is important because it helps to maintain both the plant population and yield of a particular
crop.

UNIT 15 WEEDING IN GROUNDNUTS AND CASSAVA

WEEDING GROUNDNUTS AND CASSAVA

The best time to weed is when weeds appear.

It is also recommended to weed while the crops are still young. This does not disturb the developing
roots.

METHODS OF WEEDING GROUNDNUTS AND CASSAVA

 Using hoes

 Ploughing

 Using hands

 Using chemicals

COMMON WEEDS OF GROUNDNUTS AND CASSAVA

 Chisoso (black jack)

 Msonthi

 Bonongwe (Amaranthus)

 Luba

 Namsongole (tares)

 Dawe

 Khovani
  Chilungumwamba

 Denje

 Likodza

 Kalasawene

 Volunteer crops such as maize, millet and sorghum

EFFECTS OF WEEDS IN GROUNDNUTS AND CASSAVA

 Competition for nutrients

 Competition for water

 Competition for sunlight

 Transmission of diseases

 Harbouring pests

THE DISEASES OF GROUNDNUTS

Rosette
Rosette is caused by a virus and spread by aphids. The disease restricts pod formation.
The crop has a stunted growth.

Sometimes the groundnut leaves look wrinkled with dark green or yellow colour.

Control of rosette disease

 Planting early

 Recommended spacing to prevent aphids multiplying

 Uprooting the diseased plants and burning them

 Using resistant varieties such as RG1, Nsinjiro

Leaf spot
This is caused by fungus.
There are two types of leaf spot that attack groundnuts. These are:

 Early leaf spot

 Late leaf spot

Early leaf spot shows reddish brown spots surrounded by a yellow band.

Late leaf spot shows darker and smaller spots without a yellow band around them.

Control of leaf spot

 Spraying the plants with recommended fungicides

 Growing resistant varieties

 Practicing crop rotation

UNIT 17 HARVESTING GROUNDNUTS AND CASSAVA

The success of harvesting depends on the timing of both groundnuts and cassava.

Before harvesting both groundnuts and cassava, it is important to check if they are mature.

Groundnuts
Groundnuts are mature and ready to harvest if the inside of the pod is spotted pale brown. This is
usually after three to five months from the time of planting depending on the variety.

STEPS TO FOLLOW WHEN HARVESTING GROUNDNUTS

 Dig up the plants with a hoe carefully to avoid nuts breaking off and remaining
on the ground and pull them down

 Stack groundnuts and leave the plants in the sun with pods up for few days to
dry

 Pull off the nuts from the plants, that is, strip off the nuts (kuthothola)

 Spread groundnuts on the mats to dry again for a week

Cassava
Cassava is usually mature and ready to harvest when it has been growing for one year. Cassava is usually
mature when the soil on which it grows starts to crack.
It can be harvested by cutting off the stems with a panga, removing the soil around the roots with a hoe
and then pull them out

UNIT 18 PROCESSING AND STORAGE OF GROUNDNUTS AND CASSAVA

Cassava and groundnuts need to be processed and stored properly.

Processing of cassava helps it to stay for a longer period of time and attracts high prices on the market.

Groundnuts
Groundnuts’ inside shells take 3 to 6 weeks to dry. Sometimes groundnuts are dried in stooks for quick
drying.
It is not recommended to dry groundnuts on iron sheet roofs.

Pods are then removed by hand or machine from the plant when they start to rattle. Groundnuts are
then winnowed to remove soil debris or trash.
After drying, shelling is done by hand or machine.

After shelling, groundnuts are graded to remove mouldy and broken nuts from good ones. Take note
that oil nuts such as mawanga and manipintar are usually sold in pods.
Shelled nuts may be roasted, pounded into flour and made into sauce. Sometimes farmers roast, salt
groundnuts and put them in small plastic packets. These are sold as an income generating activity at
local markets.

CASSAVA
Cassava is best stored in processed form because it does not take long to rot after harvesting. There are
two methods of processing cassava.
These are:

 Heap fermentation

 Soaking fermentation

HEAP FERMENTATION

This involves:

o peeling the outer covers

o Slicing

o Heap to ferment

o Drying
SOAKING FERMENTATION

This involves:

o Peeling

o Soaking in containers

o Cleaning

o Pounding

o Drying

Fermentation helps to remove the toxic substances from the bitter varieties of cassava and improve
taste When slicing cassava, chips or slices are prepared about 2.5 to 7.5 centimetres for easy drying.
Large chips develop moulds especially when harvesting is done in rainy season.

Sweet varieties of cassava are prepared by peeling, cutting the tubers into small pieces and boiling.

STORAGE OF GROUNDNUTS AND CASSAVA

Groundnuts
Dried groundnuts can be stored either in shelled or unshelled form. Unshelled groundnuts are stored in
sacks, granary (nkhokwe) or in clay pots. Shelled groundnuts are stored in sacks.
The sacks are stacked on planks or logs to allow free movement of air to prevent moisture which
attracts the growth of moulds on the groundnuts
Groundnuts store better in pods because it is difficult for moulds to attack. Before storage, groundnuts
need to be winnowed to clean them.

Cassava
Farmers are encouraged to store cassava in processed form such as dried pieces (makaka) or flour.
Processed cassava stay longer in storage without getting rotten.
Apply 25 grammes of actellic dust to 50kg of makaka to avoid weevil damage.

Cassava chips should be kept dry and away from wet conditions to prevent them from developing
moulds. Mouldy cassava chips are not good for consumption and cannot sell well on the market.

UNIT 19 TYPES AND IMPORTANCE OF POULTRY

Poultry means all domesticated birds.

TYPES OF POULTRY

 Chickens

 Pigeons

 Ducks

 Geese

 Turkeys

 Guinea fowls

IMPORTANCE OF POULTRY

 Source of food to people

 Beautification

 Source of manure

 Employment

 Source of raw materials

 Source of income

TYPES OF CHICKENS

 Layers

 Broilers

Layers are kept mainly for egg production Broilers are kept mainly for meat production

In Malawi farmers also keep the Black Australorp locally known as Mikolongwe. These are kept for both
meat and eggs.

BROILERS
Broilers are big, heavy and grow very fast.
They are usually ready for use at the age of 6 to 8 weeks.

The improved breeds of broilers kept for meat in Malawi include Stabro, Indian River and Ross.

LAYERS
Layers are small, light and grow slowly.

They take about 18 to 20 weeks before they start laying eggs.

There are several improved breeds of layers kept and these include Hyline, White leghorn and Shavers.

UNIT 20 SYSTEMS OF KEEPING CHICKENS 1

Chickens need proper housing to protect them from bad weather, predators and thieves. It is important
to provide enough space.
A clean chicken house will help to control diseases and parasites. There are three main systems of
keeping chickens.
These are:

 Free range system

 Semi-intensive system

 Intensive system

FREE RANGE SYSTEM

Chickens are left free all day, getting their own feed in form of green grass, insects and any leftover
food. The chickens are not restricted by a fence.
This system is adopted where there is enough land.

ADVANTAGES OF FREE RANGE SYSTEM

 Chickens can find feed for themselves

  Chickens are able to get sunshine

 Manure is well spread all over the field

 The children house does not need expensive materials to construct

DISADVANTAGES OF FREE RANGE SYSTEM

 Predators can catch the chickens

 It is difficult to collect eggs at they may be laid in the bush

 Chickens can easily catch diseases

 Difficult to control breeding

SEMI-INTENSIVE SYSTEM
The chickens are allowed to move freely during the day to eat insects, grass, worms and grit in a fenced
area. They are provided with a house to sleep at night.
Feed and water are provided within the fence. Laying nets are provided.
The house provided can either be traditional or deep litter.

ADVANTAGES OF SEMI-INTENSIVE SYSTEM

 Chickens do not go far away

 Easy to collect manure

 It is easy to control diseases

 It is easy to collect eggs

 Chickens can be fed on locally made feed

DISADVANTAGE OF FREE RANGE SYSTEM

 Feed must be provided as chickens cannot find enough feed for themselves
