A teak plantation covers 10 ha at a spacing of 1,000 trees per hectare. The volume (in m³) of a tree at age \(t\) years is given by \(V = 0.05t^{2}\) (valid up to 20 years). Timber sells for \(\N250\) per m³ and the cost of re‑planting each hectare after harvest is \(\N12,000\). Using a discount rate of 10% per annum, determine the rotation age \(H\) (in whole years) that maximises the present value of net revenue per hectare over an infinite series of rotations (Faustmann model). Also give the maximum present value (rounded to the nearest Naira).

Answer Options

Correct Answer A. Optimal rotation age = 17 years; Maximum present value ≈ \N888,800 per hectare
B. Optimal rotation age = 16 years; Maximum present value ≈ \N870,000 per hectare
C. Optimal rotation age = 18 years; Maximum present value ≈ \N905,000 per hectare
D. Optimal rotation age = 15 years; Maximum present value ≈ \N820,000 per hectare
Correct Answer
A
Correct Option:
Optimal rotation age = 17 years; Maximum present value ≈ \N888,800 per hectare
