Weakness/Remedies

Majority of the candidates were unable to:

  • enumerate the roles of science and technology in animal breeding and soil science;
  • list farm machinery and farm implements;
  • describe how the Gunter’s chain is used;
  • state the ways by which communal land tenure system and soil types affect land availability for agriculture in their country;
  • mention the problems associated with drainage system on farms;
  • mention the biotic factors that affect agricultural production;
  • state the negative effects of continuous cropping and overgrazing on the soil;
  • discuss the cultivation of maize under climatic and soil requirements, cultural practices, processing, storage and diseases;
  • state the advantages and disadvantages of afforestation;
  • give examples of the major groups of insect-pests;
  • state the functions of vitamins, proteins and carbohydrates in the diet of farm animals;
  • list viral and protozoan diseases of livestock;
  • state the sanitation practices that help to prevent disease outbreak on livestock farms;
  • mention the methods of improving local breeds of farm animals;
  • plot demand and supply curves for eggs using the schedules provided;
  • determine the equilibrium price and quantity of eggs, excess demand for eggs, excess supply of eggs;
  • suggest a way by which a farmer can take advantage of the relationship between demand and supply to attain high profit;
  • suggest ways of stabilizing the prices of agricultural produce in West Africa;
  • list the ways by which agricultural information are disseminated to farmers in the country, and
  • state the objectives of agricultural extension programmes in West Africa.

Based on the observed weaknesses, the Chief Examiners’ recommended as follow:

  • Agricultural science teachers in schools should demonstrate how farm tools, implements and machines are used to students;
  • Teachers should emphasize aspects of the syllabus that have to do with crop husbandry (cultivation) and crop pests;
  • Teachers should demonstrate to students the plotting of demand and supply curves (graphs) as well as the use of the curves to determine equilibrium price, excess demand and excess supply.
