Gce Model Questions Vol1 2024 Agricultural Science Question 3
Practice objective / multiple choice question 3 from the 2024 Gce Model Questions Vol1 Agricultural Science examination.
A farmer aims for a maize yield of at least \(6\) t ha\(^{-1}\). Yield responds linearly to total nitrogen available according to \( Y = 2 + 0.04N \) where \(Y\) is yield (t ha\(^{-1}\)) and \(N\) is total nitrogen (kg ha\(^{-1}\)). The soil already supplies \(30\) kg ha\(^{-1}\) of nitrogen. Fertiliser can only be bought in packets of \(25\) kg ha\(^{-1}\). What is the minimum amount of nitrogen fertiliser (kg ha\(^{-1}\)) the farmer must apply to meet the target yield, and what is the total cost if fertiliser costs \(120\) ₦ per kg?
