Abstract:
The interval among irrigations is an important criterion taken into account during the hidroponic cultivation of vegetables. Thus, the present work aimed to evaluate the productivity of two lettuce (Lactuca sativa L.) cultivars, Regina 2000 and Lucy Brown, in three irrigations intervals. The experiment was carried out at the Centro Universitário Luterano de Ji-Paraná (CEULJ/ULBRA), from September to December 2006. Three intervals between irrigations were used: 5; 15 and 30 minutes. Each treatment had four replications of both cultivars, in a complete randomized outline. The number of leaves.plant-1, total fresh mass and total dry mass were analyzed. There was an increase of the lettuce production according to the increase of the irrigation interval. Thus, 5 minutes among irrigations promoted the greater gain of mass for both cultivars evaluated.
