Produtividade do tomateiro em diferentes frequências de irrigação cultivado em substrato em estufa.

Abstract

: The aim of this work was to evaluate the tomato yield under different irrigation frequencies cultivated in substrate in greenhouse. The experiment was carried out in Campinas, Brazil, from November, 2003 to April, 2004. The experimental design consisted of six treatments in randomized blocks with four replications. The treatments were different irrigation frequencies: five, four, three, two and one times a day and irrigation in alternating days. The irrigation was applied by trickle irrigation system. The substrate was coconut fiber. The one, three, four and five times a day irrigation frequency provided better total marketable tomato yield. On the other hand, the irrigation frequency once a day and alternating day provided greater number of no marketable fruits. The greater number of fruits and average weight of fruit were obtained under the one, two, three, four and five times a day irrigation frequencies.
