Gce Model Questions Vol1 2022 Agricultural Science Question 12
Practice objective / multiple choice question 12 from the 2022 Gce Model Questions Vol1 Agricultural Science examination.
A 10‑ha maize farm has a potential yield of 4\,t\,ha\(^{-1}\) at a market price of $200\,t\(^{-1}\). A leaf‑blight disease affects 30\% of the plants and reduces the yield of infected plants by 15\%. A control measure can reduce the disease incidence to 5\% but costs $50\,ha\(^{-1}\). Assuming the yield loss is proportional to the incidence, calculate the net change in total profit (in dollars) for the whole farm if the control measure is applied compared with doing nothing.
