determine its viability for farm production
2b)
-Its shock can lead to fatal injury
-It is unreliable in most developing nations
-It is sometimes expensive to maintain
-It cannot be used for most driven engines
2c)
-To give an efficient work output
-To maintain lengthy lifespan
-To reduce cost of maintenance
-To avoid incessant breakdown
2d)
Land is any land that is used for either cultivation of crops or rearing of animal for human use and consumption
2e)
-Population pressure:High population pressure creates a problrm of inadequate land availability for farm production
-Minning brings more pressure on agricultural land use because it destroys farm lands
-A good topography encourages more agricultural land use
1a)
tabulate(make a table)
Substitence:
-Requires low capital
-Requires family labour
-Require small area of land
-Low farm output
-Requires low technical know how
Commercial:
-Requires high capital
-Requires mechanized farming
-Requires large area of land
-High farm input
-Requires high technical know how
1b)
i)Inadequate Land:
-Prohibition of land tenure system by government
-Leasing of land by government to farmers at subsidized prices
ii)Inadequate finance:
-Provision of loans to farmers at low interest rate by commercial banks
-Provision of farm inputs at subsidized prices by government
iii)-Practising of crop rotation
-By using disease resistant varieties
1c)
Agricultural ecology is the agricultural environment on how they affect agricultural production
1d)
Sewage,Refuse,Oil spillage,Fertilizer and drains
3a)
Staking is when yam is staked with strong stick or bamboo to ensure adequate exposure of the leaf surface to sunlight and increases yield
3b)
The nusery needs of spacing 20cm x 20cm on a field of 3mx3m on a loamy soil containing organic matter in a filled up polythene bags.The
seeds are sown with shade to prevent it from direct heating by the sun and water and weeding is done twice daily or every morning/evening
3c)

-It helps to bring vitamins to the outer layer of the grains
-It reduces the labour requirement to remove husk
-It saves time
3d)
Advantages:
-It helps to increase the farmers income and standard of living
-It gives access to forest product
-It creates employment opportunities
Disadvantages:

-Reluctance in releasing fertile soil
4a)

between two animals
-Pen mating:Is the one which a group of male and female animals are allowed to mate at random without any preference

-Video projection
6b)
-Large number of farmers can be covered
-It reduces cost of disseminating information compare to individual contact
-Energy and time of agricult5ural extension agent can be saved
-Diverse idea can be sourced through question and answers from people
6c)
Assembling as a marketing function:This is a situation whereby goods have already been purchased.It is a function that is different fom buying
6d)
Maize streak:
-It can be controlled by planting resistance varieties
-By use of insecticides

-It can be controlled by planting resistance varieties
-It can be controlled through application of chemicals
