Explanation
(a) Non-governmental agricultural organisations in West Africa
– West African Rice DevelopmentAgency/Association (WARDA)
– International Institute for Tropical Agriculture (IITA)
– International Livestock Centre for Africa (ILCA)
– International Livestock Research In-structed (ILRI)
-International Fund forAgricultural Development (IFAD)
– International Crop Research Institute for semi-Arid Tropics (ICRISAT)
– Hunger project
– Adventist ReliefAgency (ADRA)
– Catholic Relief Services (CRS)
– World Vision International
– International Centre for Research in Agroforestry (ICRAF)
(b) Ways in which agriculture and industry are interrelated
– Agriculture provides food, clothing and shelter for those who work in the industry
-Agriculture provides raw materials for industries
– Agriculture provides market for industrial prod-ucts/goods such as tools, machinery
– Agriculture promotes industrial labour
– Industries add value to agricultural produce by procesing, storing, packaging and transporting them to final consumers
– Agro-chemical industries produce fertilizers, pesticides, herbicides, fungicides, drugs and feed additives which boost agricultural production
– Seed industries provide agriculture with viable and high yielding seeds
(c) Functions of parts of a disc plough
(i) disc: It cuts into the soil and turns it over
(ii) beam: Disc standards are connected to it/ Holds disc in position/provides additional greater depth
(iii) furrow wheel: stabilises the disc plough/keeps furrows wall clean (iv) disc scraper: removes soil from the disc
(v) hitch: point of attachment to the tractor
(d) Disadvantages of animal power – Animals are susceptoble to diseases and death
– power output is low
– animals can get fatigued
– animal power is not suitable for large scale production
– the use of animal power is restricted to certain climatic zones e.g tse-tse fly free zones
– animals cannot perform optimally at certain times of the day especially during hot weather
– poor handling of animals may cause poor per-formance/animals may refuse to work when poorly handled
– animal power cannot be used to perform certain farm operations such as harvesting and processing of farm produce as they may eat up the farm produce
