Gce Model Questions Vol1 2022 Agricultural Science Question 49
Practice objective / multiple choice question 49 from the 2022 Gce Model Questions Vol1 Agricultural Science examination.
A teak plantation occupies 10 ha. Stand volume per hectare follows the logistic model \(V(t)=\frac{K}{1+a e^{-b t}}\) with \(K=200\ \text{m}^3\text{ha}^{-1}\), \(a=9\) and \(b=0.08\ \text{yr}^{-1}\), where \(t\) is age in years. The manager wants the rotation age that maximises the average annual increment (AAI) defined as \(\text{AAI}=V(t)/t\). (i) Determine the rotation age (nearest whole year) that gives the maximum AAI. (ii) Calculate the maximum AAI value (m³ ha⁻¹ yr⁻¹) at that age (to two decimal places).
