Question 5 NECO_MODEL_QUESTIONS_VOL1 • 2017 • AGRICULTURAL_SCIENCE • essay

A farmer intends to cultivate maize on 2.5 hectares of land. The recommended seed rate for the variety he will use is 25 kg ha⁻¹. Because of an anticipated 10 % loss of seed to birds, he decides to increase the seed rate by the same percentage. The soil test recommends the following fertilizer rates per hectare: nitrogen (N) = 120 kg, phosphorus as P₂O₅ = 60 kg and potassium as K₂O = 40 kg. The farmer will purchase a blended NPK fertilizer that contains 20 % N, 10 % P₂O₅ and 5 % K₂O by weight. The cost of the seed is ₦30 kg⁻¹ and the blended fertilizer costs ₦45 kg⁻¹.

Question Parts
