Neco 2021 Agricultural Science Question 27

An extension officer proposes two options to help a farmer adopt integrated pest management (IPM) on a 5‑ha maize farm.\nOption A: a training workshop costing \(150,000\) NGN plus monthly follow‑up visits of \(20,000\) NGN each for 6 months.\nOption B: a printed manual costing \(80,000\) NGN and a one‑time field demonstration costing \(100,000\) NGN.\nThe farmer expects a 15\% yield increase. Current yield is \(2.5\) tonnes per ha, market price is \(1,200\) NGN per tonne and production cost (excluding extension) is \(500,000\) NGN per ha. Which option gives the higher net benefit (increase in profit minus extension cost)? Provide the net benefit for each option and state the recommended option.
