ABSTRACT:
Physalis ixocarpa (husk tomato) is traditionally cultivated in Mexico, and nowadays the yield is low. In this study, four cultivars of husk tomato were evaluated, under greenhouse and field conditions. It was carried out a split-plot experimental design in a 4x2 factorial arrangement. The large plot was the growth conditions and the small plot was the variety. The microclimate, soil and yield variables were recorded. In the field, the Integrated Photosynthetic Active Radiation (IPAR) was higher 12mol m-2 d-1 than in the greenhouse. The average temperature was slightly higher 1.18°C in the greenhouse and the average relative humidity was slightly higher 0.89% in the field. Plants grown in the greenhouse had lower negative values for the matric potential of the soil. Water consumption and water use efficiency were 10.31 and 53.43% higher in the greenhouse that in the field, respectively. The number of fruits and yield increased significantly in all varieties grown under greenhouse conditions.
