Gce Model Questions Vol1 2023 Agricultural Science Question 46
Practice objective / multiple choice question 46 from the 2023 Gce Model Questions Vol1 Agricultural Science examination.
A farmer wishes to determine the planting density of maize that will give the highest total grain yield per hectare. Experiments show that the grain weight per plant decreases linearly with plant density: at \(30\,000\) plants ha⁻¹ the weight per plant is \(0.8\) kg, and at \(70\,000\) plants ha⁻¹ the weight per plant is \(0.5\) kg. Assuming the linear relationship holds for all densities, calculate (a) the plant density that maximises the total yield per hectare, and (b) the corresponding maximum total yield (in kg ha⁻¹).
