Tomate sweet grape cultivado com diferentes lâminas e frequências de irrigação em ambiente protegido

Abstract

Sweet grape tomatoes are increasing participation in the Brazilian market. However, information about crop management, such as water requirements during the crop is still scarce. Thus, this paper aimed to evaluate the effect of different irrigation depths and frequencies on the productive characteristics of sweet grape tomato cultivated in greenhouse production. The crop was grown in pots and irrigated by drip. We used a statistical factorial scheme design with five irrigation water depths (40, 60, 100, 120 and 140% of replacement measured with a reduced pan) with three frequencies (1, 2 and 3 irrigations per day) and four replications. The number, productivity, diameter and fruits’ length and water use efficiency (WUE) were evaluated. All evaluated attributes were statistically significantly influenced by the irrigation depths with a positive linear fit. The highest WUE value was obtained with irrigation based on the 60% replacement of the reduced pan’s evaporation.
