Growth and biomass pattern in two age group of forest tree species grown on Entisols of tropical environment

Author(s):

Abstract:
The present study was conducted to know the growth and biomass pattern in two age group of forest tree species {Adina cordifolia (Roxb.) and Mitragyna parvifolia (Roxb.)} grown on Entisols of tropical environment of Chhattisgarh during 2018-2019. For calculating the tree biomass, allometric equations relating collar girth to biomass was formulated. The stand biomass for site 1(6 years old plantation) and site 2(4 years old plantation) were 55.25 t ha-1 & 45.22 t ha-1 for Adina cordifolia & 58.71 t ha-1 & 48.23 t ha-1 for Mitragyna parvifolia, respectively. The net primary productivity values were 10.32 t ha-1 yr-1 (site 1) & 8.92 t ha-1 yr-1 (site 2) for Adina cordifolia plantation and 11.08 t ha-1 yr-1(site 1) & 9.63 t ha-1 yr-1 (site 2) for Mitragyna parvifolia plantation. Study shows that 6 years old plantation site and Mitragyna parvifolia (Roxb.) perform better, hence the same can be suggested for propagation.
