Neco Model Questions Vol1 2020 Agricultural Science Question 23
Practice objective / multiple choice question 23 from the 2020 Neco Model Questions Vol1 Agricultural Science examination.
In a maize field the yield loss caused by a particular pest is \(0.02\) tonnes per pest per hectare. The market price of maize is \(\N{₦}150\) per tonne and the cost of control is \(\N{₦}30\) per hectare. The economic injury level (EIL) is given by \(\text{EIL}=\dfrac{C}{V\times I}\) where \(C\) is the control cost per hectare, \(V\) the market price per tonne and \(I\) the yield loss per pest per hectare (in tonnes).\n(a) Calculate the pest density (pests per hectare) at which control should be applied.\n(b) If the observed pest density is 40% above this threshold, compute the expected monetary loss per hectare if no control is taken.
