Neco Model Questions Vol1 2018 Agricultural Science Question 45
Practice objective / multiple choice question 45 from the 2018 Neco Model Questions Vol1 Agricultural Science examination.
In a \(3\)-ha wheat field the expected yield without disease is \(3.5\) t ha⁻¹. A fungal disease can cause a yield loss of \(L\)% if untreated. A fungicide costing ₦8 000 ha⁻¹ reduces the loss to \(4\)% when the disease severity is \(15\)%. Assuming the fungicide reduces any loss proportionally, determine the minimum disease‑induced loss percentage (\(L\)) at which the fungicide becomes economically profitable. The market price of wheat is ₦100 kg⁻¹.
