Gce Model Questions Vol1 2023 Agricultural Science Question 35
Practice objective / multiple choice question 35 from the 2023 Gce Model Questions Vol1 Agricultural Science examination.
A mixed plantation contains teak and mahogany, each starting at a volume of 5 m³ ha⁻¹. Their natural growth follows \(V_{t}=V_{0}e^{rt}\) with \(r_{\text{teak}}=0.08\) yr⁻¹ and \(r_{\text{mahogany}}=0.05\) yr⁻¹. Over a 10‑year period the manager wishes to harvest a total of 30 m³ ha⁻¹, split equally between the two species, while ensuring that after any harvest the standing volume of each species is at least 80 % of the volume it would have had without harvesting. What is the maximum amount (in m³ ha⁻¹) that can be harvested from each species in year 5 without violating the 80 % rule?
