dc.description.abstractABSTRACT The present investigation entitled “Allometric estimation of biomass and carbon sequestration potential of some agroforestry tree species of mid-hills of Himachal Pradesh” was carried out at Dr Y S Parmar University of Horticulture and Forestry, Nauni, Solan, HP during the year 2017-18.This study aims at presenting an overview of the current knowledge on allometric relations for estimating stem volume, stem biomass, branch and leaf biomass and aboveground biomass, biomass increment, tree carbon and rate of carbon sequestration on the basis of DBH. The naturally growing scatterd trees of Bauhinia variegata, Celtis australis, Grewia optiva, Morus serrata, Leucaena leucocephala were cross-marked for the study. Volume of trees was calculated using quarter girth formula and transformed into biomass using specific gravity. Biomass was multiplied with carbon content to calculate carbon stock of the multipurpose tree species. The observations regarding diameter at breast height, tree height, crown height, crown width, crown depth, crown area and crown volume were recorded. Various linear, multi-linear and non-linear (Compound, Power, Exponential, Cubic and Quadratic) functions were analysed to estimate the volume, biomass, biomass increment, carbon stock and rate of carbon sequestration. However, in this research equation selection was based on maximum adjusted R2 and minimum standard error. Total biomass, rate of carbon sequestration and carbon content was predicted with good degree of accuracy (0.99-0.80). Adjusted R2 values for total biomass with diameter at breast height was as: B. variegata (0.93), C. australis (0.92), G. optiva (0.93), L. leucocephala (0.84) and M. serrata (0.86). Similarly, adjusted R2 values for rate of carbon sequestration with diameter at breast height were as: B. variegata (0.99), C. australis (0.80), G. optiva (0.84), L. leucocephala (0.99) and M. serrata (0.99). Further adjusted R2 values for carbon content with diameter at breast height was as: B. variegata (0.92), C. australis (0.97), G. optiva (0.90), L. leucocaephala (0.80) and M. serrata (0.87). The allometric equation developed in the present study can be utilized for estimating the availability of leaf, branch and total biomass of farmlands.en_US
