Simulating Performance of Tomato Hybrids Grown Under Canning Production System in Brazil.

Tomatoes are cultivated for industrial canning purposes in many agricultural regions of Brazil including the states of Goiás, São Paulo, Minas Gerais and Rio de Janeiro. Many cultural practices are costly, including time spent for pruning and staking plants depending on the characteristics of indeterminate growth architecture of tomato. Various architectural features of the plant and fruits determine the type of production for processing tomato or fresh consumption. In order to improve the viability of tomato production in Brazil for fresh consumption, this research focused on simulating the performance of different tomato hybrids having determinate and indeterminate growth habits and used for fresh consumption. The CSM-CROPGRO-Tomato model was parameterized for different cultivar types and production was simulated. Results of simulated production will be presented relative to goals of improving production in Brazil.
