Volume table preparation for timber yielding tree species Gmelina arborea Roxb

Abstract:
The present trial was carried out in the College of Forestry, Navsari Agricultural University, Navsari, Gujarat during 2022-23 to preparation of the volume table of Gmelina arborea. For the trial, two hundred twenty five number of sample trees were selected randomly which were categorised into diameter class wise to prepare volume table. The biometrical parameters of G. arborea such as DBH, mid diameter, height, form quotient and stem volume varied in the range of 8.40-39.24 cm, 7.63-18.48 cm, 6.70-14.43 m, 0.47- 0.91and 0.036-0.835 m³ respectively in the diameter class of 5-10 cm to 35-40 cm. In the process of preparation of volume table of G. arborea, trees having DBH from 5 to 40 cm, volumetric equation V= 0.00004D²H + 0.043 (R²=0.882) was developed and this equation was used for preparation of volume table of G. arborea. Further, for quick estimation of volume of G. arborea trees the local volume table can be used by farmers, foresters and wood merchants.
