Yield analysis of Physalis ixocarpa Brot. ex Hornem varieties under greenhouse and field conditions

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.

Effects of Plant Covers and Mulching on the Biometric Parameters, Yield and Nutritional Value of Tomatillos (Physalis ixocarpa Brot. Ex Hornem.)

“…The values of vertical diameter were higher when tomatillos were grown without soil and plant covers. Similar values were reported by Ramos-López et al [5]-3.84 cm to 4.90 cm, depending on husk tomato cultivar and cultivation method. Singh et al [38] reported a diameter of 2.27-3.73 cm for Physalis ixocarpa Brot.…”

“…'Rio Grande Verde' were grown in mulch under non-woven PP fabric covers. Similar results were reported by Ramos-López et al [5], who found that plant covers had a significant effect on the weight of husk tomato fruit which ranged from 26.10 g in cv. 'Rendidora' to 52.29 g in cv.…”

“…The average total yield of tomatillo fruit reached 1.85 kg•m −2 , and it was higher than that reported by Smith et al [22], i.e., 0.4-0.9 kg•m −2 , and similar to those determined by Maynard [54], 2.0-2.4 kg•m −2 , and Ramos et al [55], 2.52 kg•m −2 . In a study by Ramos-López et al [5], fruit yield was 4.84 kg•m −2 and 2.10 kg•m −2 when Physalis ixocarpa Brot. ex Hornem.…”

Índice de área foliar en genotipos silvestres de Physalis spp. en función de dos sistemas de cultivo

“…En este sentido, el manejo de un invernadero agrícola con respecto al sistema de temporal presenta la ventaja de controlar el suministro de agua e insumos según el estado fenológico del cultivo. Además, limita la entrada de plagas y modifica factores ambientales, tales como la temperatura, radiación solar, humedad relativa, disponibilidad de CO2, luminosidad y velocidad del viento (Peña-Lomelí et al, 2014;Ramos-López et al, 2018;Tanny, 2012). Ramos-López et al (2017) evaluaron el rendimiento de tomate de cáscara en invernadero, revestido con distintas cubiertas plásticas, obteniendo la mayor producción (3.23 kg planta -1 ) cuando fue cubierto con polietileno transparente.…”
