Abstract:

Trees are the most important component of Agroforestry, they provide, shelter, food, nutrient for soil and fodder for animals. Poplar trees have an important commercial value and can make an important contribution to the economy of the country. Tree volume equations were developed for prediction and estimation of merchantable volume. Data were collected with the aid of haga altimeter, meter tape and calliper. The measurement obtain were the diameter at breast height (D.B.H), diameter at base, diameter at top and merchantable height. Merchantable volume was calculated with the aid Newton’s formula. Data collected were subjected to Microsoft excel and using Statistical Package for the Social Scientists (SSPS) for statistical analysis. Eight linear and non linear (logarithmic) models were developed for estimation prediction of tree merchantable volume. The models developed were fitted to the data for each of the species. Coefficient of determination (R2) ranged from 77 to 99%. The statistical indices indicated that the resulting models possessed all the statistical assumption. The Schumacher–Hall’s volume was rated the best among the eight developed models. The resulting equation were tested for validation with data collected from different location and it was discovered that the models did not violet the statistical assumption. This suggests that the models are desirable for merchantable volume estimation in the study area.
