Produtividade do melão cantaloupe sob condições de diferentes lâminas de irrigação.

Abstract

This work was aimed at to evaluate the effect of five irrigation water laminas on fruit production and yield of cantaloupe melon hybrids (Hy-Mark, Torreon, Cristobal and Famosa) cultivated on a clay texture Cambisol in Quixeré-CE-Brazil during June to August 2005. The applied dayly laminas were obtained through the formula L = Kc·ETo·f,, whre L is the dayly lamina, Kc the crop coefficient in each growth stage of the crop, ETo the dayly evapotranspiration obtained from a meteorological station, and f a treatment factor (70, 85, 100, 115 and 130%). It was utilized a split-plot scheme in a randomized complete blocks design, with the laminas assigned to the plots and the hybrids to the subplots. The applied laminas did not affected hybrid responses with regards to total production and number of fruits. Productions and numbers of fruits of the hybrids, inside each lamina, were not significantly different. The 70% Kc lamina provided the greatest type 6 fruit yield, more expressively in the Famosa hybrid.
