(1) Wide range: Tractors are available in a wide range of options to suit specific tasks and requirements. A wide range of farming implements can be attached to utility tractors to help accomplish various jobs.

(2) Versatility: Though available in a wide range of models, modern tractors are designed and manufactured to offer versatility in performing a wide range of tasks.

(3) Power and Durability: Tractors are typically designed with powerful engines to run over rough terrain and pull extremely heavy loads, making them effective in tough farming or landscape tasks. 

(4) Ease of Transmission and Operation: Modern tractors feature powershift transmission and hydrostatic transmission to simplify operation. While these tractors are also provided with power steering to make turning much easier, advanced models help reduce operator fatigue with exclusive shift controls and an automatically responsive transmission.

(2) Poverty of farmers: Some farmers are poor and cannot afford to own farm machines.

(3) Inadequate machines and facilities: Are not enough where they are available.

(4) Bad nature of land (Topography): The topography of west African lands are rough and too bad for mechanization.

(5) Soil types: the soil type of West African do not suit mechanization and suitable machines have not been produced.

(6) Inadequate spare parts: Most of the machines spare parts are imported and not easily found to repair damaged parts.

(7) Inadequate Operators: Train people to handle and repair these machines are scarcely found.

Drainage is the removal of excess water which may be caused by rainfall, too much irrigation water or other origins such as canal seepage or floods, either from the ground surface or from the rootzone.

(4b)
[Pick Any THREE]
(i) Rain
(ii) Temperature
(iii) Time
(iv) Topography

(4ci)
TEMPERATURE:
(i) Increase in temperature helps in binding of the soil.
(ii) High temperature brings about weathering in soil

(4cii)
SOLUTION:
(i) It increases the degree of weathering and therefore the extent of soil development.
(ii) It results to decrease in soil PH

(4di)
(i) A good soil structure is important to allow air and water into the soil which are vital for healthy plant growth
(ii) It will improve drainage and reduce soil erosion caused by excess surface run-off
(iii) It prevents anaerobism, waterlogging and nutrient lock-up and ultimately of plants

(4dii)
(i) The structural units are approximately spherical or polyhedral.
(ii) They are bounded by curved or very irregular faces that are not casts of adjoining peds.

(6a)
(i) It reduces the quality of the crop

(iii) It affects the growth of the crop
(iv) It reduces the fertility of their seeds

(6b)
(i) Early planting
(ii) Early harvesting
(iii) Crop rotation
(iv) Mixed cropping

(6c)
(i) Maize rust: Elongated postules on both leaf
(ii) Cowpea leaf spot: Stunted growth
(iii) Groundnut Rosette: Mottling of the foliage
(iv) Coffee leaf rust: Yellowish colour if leaf

(6d)

Agricultural Extension can be defined as an informal system of education whereby information on new Innovations and ideas are disseminated to farmers

(10b)
(i) Individual contact method: This involves direct contact between the farmers and the extension officers. Such method includes farm and home visits, office call, telephone calls, correspondence and result demonstrations

(ii) Group contact method: This involves the extension officers and a group of farmers. It includes methods and result demonstrations, general meetings, lectures, workshops, field works and excursions.

(iii) Mass media: This method involves the reaching of many people with extension messages. These messages must be general so as to be of interest to all. Such mass media include posters, agricultural shows , leaflets, cinema, newspaper/magazines, radio and television
