Abstract

The aim of this study was to evaluate the quality fit of nonlinear models, gompertz and logistic data outside diameter, longitudinal (DEL) and transverse (DET) fruits of green dwarf coconut trees, as well as verification of the existence of residual autocorrelation. The results showed that for both, DEL and DET, the logistic model is most appropriate for describing the fruits growth. The fit of the models, for both variables, showed positive residual autocorrelation. For DEL, the residual was modeled by a first order autoregressive process, and for DET, the autoregressive process was considered of second order. Consideration of the autoregressive process resulted in more accurate estimates of the parameters. According to the logistic model, the fruit of the dwarf green, fully developed, have external diameters, longitudinal and transverse, respectively, of 21.56cm and 15.35cm.
