Neco 2025 Agricultural Science Question 30
Practice objective / multiple choice question 30 from the 2025 Neco Agricultural Science examination.
A 8‑ha cassava farm normally yields \(10,000\) kg per hectare. Disease X causes a 25\% yield loss when its incidence is 15\% of the plants. By applying a control measure the incidence is reduced to 5\% and the control costs \(\text{₦}180\) per litre, with a dosage of 0.6 L per hectare. The market price of cassava is \(\text{₦}120\) per kg. Assuming the yield loss is proportional to incidence, calculate the net gain (increase in revenue minus the cost of control) in Naira compared with doing nothing.
