Waec Model Questions Vol1 2021 Agricultural Science Question 14
Practice objective / multiple choice question 14 from the 2021 Waec Model Questions Vol1 Agricultural Science examination.
A forest of 150 ha is to be managed for timber. The stand volume per hectare at different ages is given: Age (years) - Volume (m³ ha⁻¹) 10 - 80 15 - 150 20 - 210 25 - 260 30 - 300 The manager wants to adopt a rotation age that maximizes the mean annual increment (MAI). (i) Determine the rotation age that gives the highest MAI. (ii) Calculate the total timber (in m³) that will be harvested each rotation at that age. (iii) If the average volume of a mature tree at that age is 0.75 m³, estimate the number of trees that must be present per hectare at the start of rotation to achieve the projected volume.
