Description
Summary:This paper aims to evaluate the lettuce crop, type "Mimosa Roxa", submitted to the influence of nitrogen and hydrogel in Latossolo Vermelho distroferrico (Oxisol). The study was conducted at the Universidade Federal da Grande Dourados (Federal University of Dourados Great), in Dourados, MS. A completely randomized split plot delineation was used with three blocks. Each plot consisted of six doses of nitrogen applied to the irrigation water and the subplots consisted of five levels of hydrogel applied to the soil. Transplantation of seedlings to the garden occurred on Jul 15, 2013, and plants were harvested 53 days after transplanting. During the lettuce cycle, irrigation management was based on monitoring the water status of the soil using a soil moisture sensor. The doses of hydrogel linearly influence the efficiency of water use by lettuce. The fresh and dry weight of the shoots presented maximum values with the nitrogen doses of 123.04 and 118.51 kg ha super( -1), respectively.
