Assessment: WAEC SSCE - Agricultural Science - 2008 (Objective) Subject: Agricultural Science

Question 1 Report

Which of the following crops should be planted on a piece of land that has been repeatedly cropped with maize?
Answer Details
When a piece of land is repeatedly cropped with maize, the soil nutrients may become depleted, and diseases and pests that affect maize may build up. Therefore, it is best to plant a crop that is not susceptible to the same pests and diseases and that can utilize different nutrients from the soil. Of the options given, cowpea would be the best choice because it is a leguminous crop that can fix atmospheric nitrogen into the soil and it is less susceptible to the pests and diseases that affect maize.
