Neco Model Questions Vol1 2022 Agricultural Science Question 5
Practice objective / multiple choice question 5 from the 2022 Neco Model Questions Vol1 Agricultural Science examination.
A farmer intends to plant maize on 3 ha. Soil analysis shows available nutrients of N = 40 kg ha⁻¹, P₂O₅ = 15 kg ha⁻¹ and K₂O = 30 kg ha⁻¹. The target nutrient levels for optimum yield are N = 120 kg ha⁻¹, P₂O₅ = 60 kg ha⁻¹ and K₂O = 80 kg ha⁻¹. Fertiliser options are: urea (46 % N) at ₦45,000 t⁻¹, single superphosphate (20 % P₂O₅) at ₦55,000 t⁻¹, and muriate of potash (60 % K₂O) at ₦50,000 t⁻¹.\n(i) Calculate the amount (kg) of each fertiliser required per hectare to meet the target nutrient levels.\n(ii) Compute the total cost of fertilisers for the whole 3‑ha area.
