Neco 2022 Geography Question 3
Practice objective / multiple choice question 3 from the 2022 Neco Geography examination.
A farmer intends to grow maize on \(5\) ha. Without fertilizer the expected yield is \(2.5\) t ha\(^{-1}\). Applying nitrogen fertilizer increases yield according to \(Y = 2.5 + 0.8\sqrt{N}\) (t ha\(^{-1}\)), where \(N\) is the amount of nitrogen applied per hectare (kg ha\(^{-1}\)). Fertilizer costs \(\text{₦}150\) per kg of nitrogen and the market price of maize is \(\text{₦}250\) per kg. The farmer has a maximum fertilizer budget of \(\text{₦}120{,}000\). Determine the optimal amount of nitrogen per hectare to maximise profit and compute the maximum profit (in naira, rounded to the nearest naira).
