Growth and Yield Prediction Models for Acacia auriculiformis Grown in the Plantations of Bangladesh

Acacia auriculiformis is a very fast growing species belonging to the family Leguminosae that have been introduced in the plantations in Bangladesh for their faster growth and wide range of adaptability. The present study aimed at development of growth and yield prediction models for the species using simultaneous equation method. Models were selected for the species to estimate the stand height, stand dominant height, stand diameter, stand basal area per hectare and volume yield per hectare. Paired t-test, 45-degree line test, per cent absolute deviation and biological principle of stand development were used for the validation of chosen models. The results suggest that the models derived were statistically and biologically acceptable and could be satisfactorily used for stands of Acacia auriculiformis of ages 3-9 yeara and site indices of 13.47 to 19.20 m based on a base age of 6 years in the central region of Bangladesh.
