Características qualitativas do melão (Cucumis Melo l.) cultivado em ambiente protegido e irrigado por gotejamento.

Abstract

The experiment was carried out at UFLA, Lavras/MG and its objective was to study the effects of depth of irrigation on the fruit quality of greenhouse cultivated melon (Cucumis melo L., var. Inodorus, cv. Vereda). The crops was drip irrigated in a two days interval. Irrigation depsths were computed using a four different fractions of the evaporation depth observed on a reduced calss A pan evaporimeter (ECAr): 0.5*ECAr; 0.75*ECAr; 1.0*ECAr and 1.25*ECAr. Each irrigation treatment was applied to three plant rows, each one cntaining 8 plants. Only 6 plants located at the central row of each treatment were used for measurement. Evaluated parameters were: total soluble solids content (SST), total title acidity (ATT) and pH from six fruits each treatment of irrigation. SST an ATT were significantly affected by irrigation depth, there was trend on reduced values as irrigation depth increases.
