Independent and simultaneous modeling of biomass and carbon of Guinean Elaeis

Abstract

The objective of this study was to perform and evaluate the modeling for individual and aboveground components of biomass and carbon in palm crops by independent and simultaneous estimation in different cultivation ages. The data collection was performed in a commercial pam crop in Taperoá, state of Bahia. Five models were tested and the best one was chosen based on statistical criteria of adjusted R2, Syx (%), AIC and graphical analysis of the residuals for independent adjustments and the best equations for each component were adjusted simultaneously. Biomass and carbon showed good correlation with the stipe height and total height, which was identified by path analysis. The simultaneous estimation demonstrated satisfactory results in the statistical criteria when compared to the independent estimates, being it total or by compartments.
