Neco 2018 Agricultural Science Question 1
Practice objective / multiple choice question 1 from the 2018 Neco Agricultural Science examination.
If a forest area of 10 ha is planted with 2000 seedlings per ha of species X. The initial DBH is 2 cm and height 0.5 m. Each year the trees increase in DBH by 2.5 cm and height by 0.6 m. After 5 years, 85% of the seedlings survive and a thinning removes 30% of the surviving trees. The remaining trees continue to grow until age 20 years (i.e., 15 more years). The merchantable volume per tree at age 20 is estimated by \(V = 0.0001 d^{2} h\) cubic metres, where \(d\) is the DBH in cm and \(h\) is the height in metres. Calculate the total merchantable volume from the whole forest at age 20.
