Psidium guajava Linnaeus., popularly
known as ‘Apple of Tropics’ is one of the major fruit
crops undertaken on the bouldery riverbed lands of
North - Western 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 = aXbwhere 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 R
values for the fitted functions varied from 0.89 to 0.99.
The calculated t - statistic values for all the components
found to be non - significant (p [0.05]) 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
1.43 Mg ha - 1 in 4 year to 40.54 Mg ha - 1 in 14 year
old plantation. Mitigated carbon varied from 0.26 in
4 year to 7.75 Mg ha - 1 in 14 year of plantation. The
total biomass carbon stocks varied from 0.48 Mg ha
(4 year) to 13.66 Mg ha - 1 (14 year) guava plantation.
