Abstract:
The present trial was carried out in the Navsari Agricultural University, Navsari, Gujarat during 2022-23 to develop volumetric equation 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 develop the volumetric equation with the measured tree parameters. 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. Among all the linear regression equations developed, equation V = 0.00004D2H + 0.043 having maximum R2 value of 0.881 was found best. Further, for quick estimation of volume standing G. arborea trees, this equation can be useful for farmers, foresters and wood merchants.
