ABSTRACT = {The aim of this study was to evaluate some physiological aspects of papaya crops in semi conventional and organic
production systems. The following factors assessed in this experiment were: 1. Production systems (organic and semi
conventional); 2. Genotypes (Maradol and Maradona F1), and 3. Cover crop plants (Canavalia, vegetative cover
and no cover). Twelve treatments were obtained -product of factors’ combination- and distributed under a threerepetition experimental design of subdivided parcels. The factors examined in this study, that changed the CO<sub>2</sub>
assimilation rate, were production system and genotype. It was determined that the greatest gas exchange in papaya
crops happened at 13:40 h but achieving the highest CO<sub>2</sub> assimilation was also affected by the production system
and genotype. Similarly, they showed some effects in CO<sub>2</sub> assimilation, transpiration, stomatal conductance, intercellular CO<sub>2</sub>, leaf temperature, chlorophyll, and temperature. In general, the combination of factors that accentuated
in this experiment were the semi conventional-Maradona-Canavalia with a crop yield of 53.5 t ha<sup>-1</sup>, followed by
treatments organic-Maradona-no cover and semi conventional-Maradona-vegetative cover.},
