Statistical Analysis of Growth and Biomass Production Data in some Multipurpose Trees

Abstract

Statistical analysis of data pertaining to three fuel-cum-fodder trees viz; Acacia tortilis, Hardwickia binata and Leucaena leucocephala planted under agro-silvipasture and farm forestry experiments have been discussed, in the light of normality of data. 54, 39 and 50 samples of size 20 each belonging to these tree species have been chosen for deciding the criterion of transformation function. Sample size with desired variation in mean above-ground biomass in tree have also been discussed. It has been found that logarithmic transformation is most suitable for Acacia tortilis and Hardwickia binata while square root function for Leucaena leucocephala. Sample size with desired 10% apartness from mean were found as 95-100% in case of L. leucocephala, 68% in A. tonilis and 15% in H. binata of available plants.
