| ABSTRACT The aim of this work was to evaluate, under the Cerrado conditions of Central Brazil, the effect of different amounts of water and nitrogen (N) on the production performance of hybrid squash Tetsukabuto. Five water depths were tested in 2008 (185, 265, 343, 408 and 477 mm) and four in 2009 (286, 360, 430 and 540 mm), using line source sprinkler irrigation. The doses of N (0, 50, 100, 150 and 200 kg/ha) were the same in both experiments. The experimental design was a split-plot strip block with three replications. Fruit productivity was affected by the interaction between water depths and doses of N. Higher marketable productivity was observed on plants cultivated with the use of 477 and 492 mm of water and 105 and 146 kg/ha of N in 2008 and 2009,... |
