The growth and yield models/tables for Gmelina arborea Roxb. (gamar) in the plantations of Bangladesh have been prepared based on site indices. Models were derived by the data collected from permanent sample plots and also from temporary sample plots. Step-wise and all probable combinations of the independent variables methods were used to select the best suited models subject to the satisfaction of the statistical and biological requirements. Models were selected to estimate the stand dbh,stand mean height,stand basal area per hectare, total overbark volume yield per hectare and underbark volume yield per hectare upto top-end diameter of 10.0 cm. The yield prediction models derived in the study could satisfactorily be used for gamar plantations within the limitations ofstands of ages 3-12 years and site indices of 7.5 to 20.0 meters based on a base age of 12 years.
