Evaluación del rendimiento de tomate riñón (lycopersicum esculentum mill) var. daniela en dos tipos de invernaderos, parroquia Calpi, cantón Riobamba.

Abstract

The aim of this study was to evaluate the yield of kidney tomato (Lycopersicum esculentum Mill.) Daniela variety in two different types of greenhouses (technified and conventional). Fifty plants were taken at random and agronomic variables such as phenological stages, percentage of survival, presence of pests and diseases were evaluated. At the end of the fruit harvest, the respective tests were carried out on both the first and second storey, in terms of yield, fruit diameter, fruit firmness and brix degrees. The respective equipment was used to measure relative humidity, soil humidity and temperature, and their influence on the development of the crop and yield, as well as the economic analysis of the benefit/cost ratio. As for the statistical analysis, the Student's t- test at 5% was used for each of the parameters studied to establish whether or not there were significant differences between treatments. The technified greenhouse obtained the best conditions for the development of its phenological stages as opposed to the conventional greenhouse, about 15 fruits per plant were harvested, with a yield of 47.66 t/ha, fruit diameter 12.46 cm with a firmness of 60 N and 10 brix degrees. As for the benefit-cost ratio, this obtained 1.46 dollars with a profitability of 46%. The best results were obtained with the technified greenhouse.
