This study aims at investigating the effects of allelopathy of G. arborea on the growth of P. kesiya. Forty sample plots were established on five transects using systematic sampling in which Diameter at Breast Height (DBH), Height (H) of 400 trees and Distance (d) from G. arborea firebreak were measured. The statistical analysis was done based on regression analysis, while analysis of variance (ANOVA) was used to establish the statistical difference of plots at different distances from the G. arborea firebreak. The results from this study showed that height and DBH of P. kesiya depend on the planting distance from G. arborea fire breaks. Two independent models of the form ln(Y) = a+xln (d) were formulated based on height and DBH as response variables, and distance from the fire breaks a... view more»
