ABSTRACT:
The aim of this paper was to test nonlinear regression models for estimating the cherry tomato production and to identify the plot size with better fitting quality and adjustment of the models, using two uniformity trials in greenhouse. The logistic and von Bertalanffy models were used on variables, as the means fruit weight, the means number of fruits and bunches accumulated in the multiple harvests and with different plot sizes. The models presented similar estimates for all parameters in all plot sizes studied. The nonlinear models adequately describe the behavior of the production of cherry tomato fruits cultivated in greenhouse. Plots constituted by two and three plants, respectively in trials with greenhouse of 250 m2 and 200 m2, provide a good fitting quality in the models adjustment.
