A farmer cultivates maize on 10 ha. The base yield without inputs is \(2.5\ \text{t ha}^{-1}\). Applying fertilizer increases yield by 20 % per ha, but the fertilizer has an efficiency factor of 0.85 (only 85 % of the potential increase is realized). A pest reduces the actual yield by 15 % of the yield after fertilization. The farmer may apply a pesticide costing ₦30,000 per ha, which reduces pest loss to 5 % of the post‑fertilization yield, provided the fertilizer efficiency is at least 0.80. Fertilizer costs ₦20,000 per ha. The market price of maize is ₦150,000 per tonne. Determine for the two scenarios (i) fertilizer only, (ii) fertilizer plus pesticide: (a) total yield (t), (b) total cost (₦), (c) profit (revenue minus cost). Which scenario yields the higher profit?

Answer Options

A. Scenario (i): yield ≈ 24.86 t, cost = ₦200,000, profit ≈ ₦3,600,000. Scenario (ii): yield ≈ 27.79 t, cost = ₦500,000, profit ≈ ₦3,500,000. The fertilizer only scenario yields the higher profit.
B. Scenario (i): yield ≈ 24.86 t, cost = ₦220,000, profit ≈ ₦3,509,000. Scenario (ii): yield ≈ 27.79 t, cost = ₦530,000, profit ≈ ₦3,650,000. The fertilizer + pesticide scenario yields the higher profit.
Correct Answer C. Scenario (i): yield ≈ 24.86 t, cost = ₦200,000, profit ≈ ₦3,529,375. Scenario (ii): yield ≈ 27.79 t, cost = ₦500,000, profit ≈ ₦3,668,125. The fertilizer + pesticide scenario yields the higher profit.
D. Scenario (i): yield ≈ 23.75 t, cost = ₦200,000, profit ≈ ₦3,362,500. Scenario (ii): yield ≈ 26.50 t, cost = ₦500,000, profit ≈ ₦3,475,000. The fertilizer + pesticide scenario yields the higher profit.
Correct Answer
C
Correct Option:
Scenario (i): yield ≈ 24.86 t, cost = ₦200,000, profit ≈ ₦3,529,375. Scenario (ii): yield ≈ 27.79 t, cost = ₦500,000, profit ≈ ₦3,668,125. The fertilizer + pesticide scenario yields the higher profit.
