Most of the candidates were unable to:

  1. discuss the importance of agriculture under the following headings:

  2. define hygroscopic water, capillary water and gravitational water;

In view of the weaknesses noted above, the chief examiners advised that

    • the teaching and learning of agriculture should be made more practical oriented with adequate exposure of the candidates to modern ways of farming;
    • excursion and field trips to agricultural institutions and commercial farms should form part of the course requirements for agricultural science in schools;
    • Agricultural science graduates should be made to teach the subject for an in-depth teaching and learning.
