dc.description.abstract Agar tree (Aquilaria malaccensis Lamk, Family- Thymeleaceae) has drawn unique position due to the production of world’s most expensive essential oil used in fragrances and also medicine. It is one of the most valuable and economically important commercial tree speciesplanted in some potential forest areas of Bangladesh. The main aim of this study is to develop mathematical models for total volume estimation of Agar tree. In order to meet the requirements we have selected 21 models of volume equation which are tested by regression technique. Among them for one way volume equation 2 V  a  bD  cD and for two way volume equationV a bD cH dD H 2     appeared to the best model for estimating the Agar tree volume.From these models conversion factors equationFr = D/(a+bD+cD2)(r =11, 13, 15) has been determined to estimate under bark volume and under bark volume of different top end diameters of 11, 13, and 15 centimeters. en_US
