Características produtivas do melão (Cucumis melo L.) cultivado em ambiente protegido e irrigado por gotejamento.

Abstract

The objective of this study to evaluate the effect of different irrigation depths on melon growing in greenhouse. The experiment was conducted in an experimental area of the Engineering Departament of the Universidade Federal de Lavras, Lavras/MG. Melon (Cucumis melo L., var. Inodorus, cv. Vereda) was drip irrigated, in a two days interval, with four different depths. Irrigation depths were computed using a four different fractions of the evaporation depth observed on a reduced class A pan evaporimeter (ECAr): 0.5*ECAr, 0.75*ECAr, 1.0*ECAr and 1.25*ECAr. Each irrigation treatment was applied to three plants rows, each one containing 8 plants. Only 6 plants located at the central row of each treatment were used for measurement. Evaluated parameters were: average weigth and fruti longidutinal and transversal diameters. None of the evaluated parameters were significantly affected by irrigation depth. The highest average fruit weigth and yield was observed on the treatment receiving 1.0*ECAr.
