Abstract(s)
The objective of this paper was to adjust nonlinear regression models for the fruit production of two
vegetable species and to identify the plot size with the best explanatory power and model adjustment. The
logistic and von Bertalanffy models were used on variables of means fruit weight and means number of
fruits accumulated in multiple crops and with different plot sizes. The models presented similar estimates
for all parameters in all plot sizes, and they described the behavior of fruit production in Cucurbita pepo
and Capsicum annuum cultivated in plastic greenhouses. Plots of C. annuum consisting of seven plants and
plots of C. pepo consisting of four plants are recommended in order to provide results of a high enough
quality for model adjustment.
