Neco 2017 Agricultural Science Question 48
Practice objective / multiple choice question 48 from the 2017 Neco Agricultural Science examination.
A pest causes a 0.5\% loss of yield per insect per plant. The crop yields 5 tonnes per hectare and the market price is \(\text{₦}250\) per kilogram. An insecticide costs \(\text{₦}20{,}000\) per hectare and reduces the pest population by 90\%. Using the economic injury level formula \(EIL = \frac{C}{V \times I \times K}\), where \(C\) is control cost per hectare, \(V\) is market value per hectare, \(I\) is injury per insect (as a proportion of yield), and \(K\) is the proportion of damage prevented, calculate the EIL in insects per hectare (round to the nearest whole insect).
