Abstract

Psidium guajava Linnaeus popularly known as ‘Apple of Tropics’ is one of the major fruit crops undertaken on the bouldery riverbed lands of NorthWestern Himalayan region Different predictive models were fitted to establish a functional relationship between biomass and collar diameter CD of the tree Out of seven different models attempted viz Monomolecular Logistic Gompetz Allometric Rechards Chapman and Linear Allometric model Y = a Xb where Y = total biomass X = collar diameter a and b = parameter estimates fulfills the validation criteria to the best possible extent and is considered as best performing Allometric model has been fitted to find the relationship between biomass of different tree components and collar diameter All the equations indicated high correlation between biomass and collar diameter and the R2 values for the fitted functions varied from 089 to 099 The calculated tstatistic values for all the components found to be nonsignificant p  005 which clearly reveals the validity and reliability of the model The developed allometric models were used to estimate the biomass and carbon stocks of P guajava plantations of the study site The estimated total biomass varied from 143 Mg ha−1 in 4 year to 4054 Mg ha−1 in 14 year old plantation Mitigated carbon varied from 026 in 4 year to 775 Mg ha−1 in 14 year of plantation The total biomass carbon stocks varied from 048 Mg ha−1 4 year to 1366 Mg ha−1 14 year guava plantationThe authors are thankful to Director Indian Institute of Soil and Water Conservation Dehradun India for providing necessary facilities to carry out the study The help rendered by Mr Chatar Singh and Dr Gambhir Singh in data collection and soil samples analysis is gratefully acknowledged
