RACIONALIZAÇÃO DE RECURSOS HÍDRICOS COM AUXÍLIO DE POLÍMERO HIDRORETENTOR NO CULTIVO DE TOMATE SWEET GRAPE cv. BRS ZAMIR

Abstract

In view of the current scenario of water scarcity, the objective of this work was to study the behavior of Sweet Grape tomatoes, to cultivate BRS Zamir, under the effect of different irrigation depths and different doses of water-retention solution, in a protected environment. The experiment was carried out in the experimental area of the Federal Goiano Institute (IF Goiano), Campus Urutaí-GO. It was used for the experiment the statistical design of randomized blocks in a factorial scheme (4x4) with subdivided plot and four blocks, in which four levels of irrigation (25, 50, 75 and 100%) of the evaporation obtained daily by the micrometer were used. hook and five doses of hydrogel solution (0, 300, 600 and 900 mL). All variables analyzed were subjected to analysis of variance by the F test. It was concluded that there was no interaction between irrigation depths and hydrogel doses. For the number of commercial fruits, the 100% ETc irrigation blade provided greater development. Fresh matter, on the other hand, developed more when 600 mL of hydrogel volume was used.
