The study's goals were to develop biomass equations for cashew plantation in Cameroon. A total of 60 cashew trees were measured within 30 were destructively sampled to determine biomass content in tree components. The regression equations relate AGB with DBH and height (H) were computed and the models were tested for accuracy based on observed data. The best model was selected based on higher adj R2 and lower Akaike information criterion than rejected models. The relations for all selected models are significant (p<0.000), which showed strong correlation AGB with selected dendrometric variables. The fit of the allometric biomass models AGB is Ln (AGB)=4.66+0.28 × Ln (D). The specic allometeric equation is developed for cashew which can be used in similar ecosystem in Cameroon for the implementation of Reduced Emission from Deforestation and Degradation (REDD+) activities to benefit the local communities from carbon trade.
