Regional Volume Table for Gurjan Oil Trite (Dipterocarpus turbinats, Gaertn-syn, Dipterocarpus indicus-Bedd.) and its Certain other Relationships (Data From Karnataka.)

Volume tables for 'Gurjan' (Dipterocarpus turbinatus, Gaertn) have been prepared by the method of linear regression. The model used is V = a+b D² d. The equation gives highly significant result. Table for the total stem wood (over bark) has been given. Similarly diameter at b h. and height table has been prepared by the method of curvi-linear regression. The model used is : 1/H = a/D + b. The equation gives highly significant result. The ration between the girth and average diameter at breast height (1.37m from the ground level) has been determined. Similarly, relationship between girth at 15cm from the ground level and breast height has been determined.
