Question 3 NECO • 2023 • AGRICULTURAL_SCIENCE • objective

In a 5‑ha field a disease currently attacks 12\% of the area. Each percent of incidence reduces the yield by \(0.05\) tonne per ha. The crop sells for \(\text{N}150\) per tonne. A fungicide reduces the incidence by 70\% of the infected area but costs \(\text{N}200\) per ha. The disease‑free yield is 3 tonnes per ha. Should the farmer apply the fungicide?

Answer Options

A. Yes, because the fungicide cost is offset by the increased yield, giving a net profit of (N2000) compared to (N1800) without treatment.
B. Yes, because the net profit after treatment (N1900) is higher than the profit without treatment (N1800).
Correct Answer C. No, because the net profit after treatment (N1115) is lower than the profit without treatment (N1800).
D. No, because the net profit after treatment (N1500) is lower than the profit without treatment (N1800).
Correct Answer
C
Correct Option:
No, because the net profit after treatment (N1115) is lower than the profit without treatment (N1800).
