(1ai)
Farm Mechanization is the application of Engineering principles and Technology in agricultural Production, storage and Processing on the Farm.
(1aii)
(i) There is low level of technical know-how about machinery.
(ii) Unfavorable soil terrain or topography prevents mechanization
(iii) It is costly or expensive to hire machines and most farmers are poor.
(iv) Small farm holding or land fragmentation or land tenure system does not permit mechanization.
(1b)
(i) Addition of Manure/ Agro-chemicals such as Fertilizers, pesticides and insecticides.
(ii) Early Planting.
(1c)
(i) To provide portable water to the rural people for increased agricultural production.
(ii) To bring more land under cultivation by increasing the farm through the provision of land clearing services. e.g. Tractor hiring at minimum cost.
(1di)
(i) Government should stabilize prices of farm produce in the country.
(ii) Community board should be re-established to help organize the marketing of agricultural produce.
(iii) Government should buy excess produce from farmers.
(1dii)
(i) Water conservation techniques, such as mulching should be practiced.
(ii) Planting cover crops such as centrosema spp should be practiced as it helps to conserve and prevent evaporation of water from the soil.
(iii) Irrigation practices which is the artificial supply of water to farmland should be adopted in areas of low rainfall.
=======================================
(4a)
Soil Drainage is the total withdrawal of excess water from the soil while at the same time retaining adequate reserves to carry the crops through the period of scarcity.
(4b)
(i) Mulching the soil: Mulching sandy soil prevents water loss through evaporation and nutrient loss by water erosion.
(ii) Avoidance of Bush Burning: Bush Burning promotes soil erosion, kills soil organism and remove organic matter which can contribute to the fertility of the soil.
(iii) Application of Compost Manure: Compost manure helps to bind the sand particles together and also add humus(nutrients) to the soil.
(iv) Planting Cover Crops: Cover Crops help to provide shade, prevent erosion and add more nutrients to the soil.
(4c) Loading....
(4d)
(i) Copper.
(ii) Boron.
(iii) Iron.
(iv) Zinc.
(v) Chlorine.
=======================================
(5a)
(i) Threshing: This is the separation of the grains from the stalk by either beating with stick, treading with feet or by the use of mechanical threshers.
(ii) Hulling: This is the removal of the husks from the grains. The grains are pounded gently to remove the expanded husks. The husks are then separated from the rice by winnowing.
(iii) Fermentation:Fermentation is the process in which a larger substance breaks down into a simpler substance. Eg. Bread, Yogurt
(5b)
(i) Pest and Diseases.
(ii)
(5c)
(i) Colouration on the leaves.
(ii) Low yield of the crop.
(iii) Stunted Growth.
(5d)
(i) Yam Setts.
(ii) Yam Seeds.
(iii) Yam Minisetts.
(5e)
(i) Gross Michel.
(ii) Canary Banana

(ii) Protein Concentrate.
(7b)
(i) Vitamins.
(ii) Protein.
(7ci)
(i) For Meat/Food/Milk Production.
(ii) Highly prolific i.e. producing twins and triplets two times a year.
(iii) High Economic Value/Feeding cost is Low.
(iv) For employment/educational purpose e.g. teaching and research and easier to keep.
(7cii)
(i) Foot and Mouth Diseases.
(ii) Rinderpest Diseases.
(iii) Trypanosomiasis.
(iv) Red Water Fever.
(7d)
(i) Proper Vaccination of the Animals.
(ii) Good Hygiene and Sanitary measures.
(iii) Good and Regular Feeding.
(iv) Overcrowding of animals should be avoided.
=======================================
(10a)
Supply can be defined as the quantity of goods (rice) which a producer is willing and ready to offer for sale at a given price over a given period of time.
OR
Supply is defined as the ability and willingness to offer for sale specific quantities of Rice at alternative prices, over a given period of time.
(10b)
(i) Price: The higher the price of any goods, the lower the quantity that will be demanded.
(ii) Income of the Consumer: The higher the income of the consumer, the higher the quantity of commodities that will be demanded.
(iii) Population: Increase in population will lead to high demand of commodities.
(iv) Taxation: Increase in taxation means a reduction in purchasing power which may result in decrease in the demand for certain goods.
(10ci)
(i) Farm Settlement Schemes.
(ii) Agro-services Centers.
(iii) River Basin and Rural Development Authorities.
(iv) National Agricultural Land Development Agency.
(v) Operation Feed the Nation.
