Capital city of Uttar Pradesh Lucknow, comes in the Northern sub-tropical region
of India. It comes under the central plain region and contains highly fertile soil for agriculture,
but Lucknow and its nearby districts such as Hardoi, Sitapur, and Unnao are known for the
finest Mango (Mangifera indica ) cultivars, ʽDashehariʼ is one of them. The ʽDashehariʼ an
endemic mango landrace is famous across the country. ʽDashehariʼ trees are huge and have a
wide canopy, which influences mitigating the atmospheric carbon through balancing the
carbon cycle. This study has been focused on the estimation of ʽDashehariʼ tree biomass. In
this research, an effort has been done to minimize error and standardize key factors while
estimating tree biomass. Although, generalized allometric equations have mainly been used as
a forest measuring tool to estimate above-ground biomass, but applying these equations to
other commercial trees, either gives uncertain results or which varies too much differently.
Therefore, eighty years old seedlings of Dashehari trees were harvested with a legal permit.
Above-ground biomass of every mango tree has been calculated by the destructive method as
well as non-destructive methods. Subsequently, measurements of the trees and comparative
findings were evaluated by statistical analysis. The study showed that by the non-destructive
method, wood density influences the estimation of the biomass of the tree. Above-ground
biomass was recorded as higher than the destructive method while using standard wood
density value (0.60 g cm-3), whereas above-ground biomass was recorded as almost similar to
the destructive method while using modified wood density (0.48 g cm-3).
