Neco Model Questions Vol1 2017 Geography Question 42
Practice objective / multiple choice question 42 from the 2017 Neco Model Questions Vol1 Geography examination.
A farmer intends to grow maize on \(10\) ha of land. The expected yield without fertilizer is \(2.5\) t ha⁻¹. Applying nitrogen fertilizer increases yield as follows: - The first \(100\) kg ha⁻¹ adds \(0.8\) t ha⁻¹; - Each additional \(20\) kg ha⁻¹ beyond the first \(100\) kg adds only \(0.2\) t ha⁻¹ (diminishing return). The farmer can purchase at most \(1200\) kg of fertilizer in total. Fertilizer costs \(₦30\) per kg. The market price of maize is \(₦120\) per kg. A pest outbreak reduces the actual yield by \(10\)% after the fertilizer effect. Determine the amount of fertilizer (in kg ha⁻¹) the farmer should apply to maximise profit and compute the maximum total profit (in ₦).
