Neco Model Questions Vol1 2018 Agricultural Science Question 20
Practice objective / multiple choice question 20 from the 2018 Neco Model Questions Vol1 Agricultural Science examination.
A farmer plans to apply nitrogen fertilizer to a maize field. Soil already supplies 30 kg N ha⁻¹. The yield response to added nitrogen (N kg ha⁻¹) follows \( \Delta Y = 0.05N - 0.0002N^{2} \) (tonnes ha⁻¹) for 0 ≤ N ≤ 250, after which no further increase occurs. The base yield without added nitrogen is 2 t ha⁻¹. Maize sells for ₦40,000 per tonne, fertilizer costs ₦120 per kg, and fixed costs are ₦15,000 ha⁻¹. Considering only whole‑ten kilogram increments of N, determine the amount of nitrogen to apply (kg ha⁻¹) that maximizes net profit per hectare and state the maximum profit (rounded to the nearest thousand Naira).
