Conteúdo: 	The management of the irrigation is fundamental for success of leaves vegetables production. The work was carried out aiming to evaluate the production response of the arugula (Eruca sativa Mill.) under different irrigation levels at 25, 31, 37 and 43 days after sowing. The treatments were distributed in randomized blocks design with four replication, and evaluated in split-plot The management of the irrigation is fundamental for success of leaves vegetables production. The work was carried out aiming to evaluate the production response of the arugula (Eruca sativa Mill.) under different irrigation levels at 25, 31, 37 and 43 days after sowing. The treatments were distributed in randomized blocks design with four replication, and evaluated in split-plot scheme of 4 x 4, with the plots constituted by four irrigation levels equivalent to reference evapotranspiration (ET0) at 50%, 75%, b100% and 125% estimated by Penman-Monteith equation; and the split-plot constituted by days after sowing. The arugula planting was established in November of 2008 with direct sowing in nursery with 0.1 m x 0.2 m per plant, using the cv. ?Folha Larga?. After the germination phase was carried out crop management necessary to the crop production. It was analyzed: plant height (cm), leaf number, fresh weight (g m-2) and dry weight (g m-2). The results showed the significant differences at level of 5% of probability for the Scott-Knott test for all variables analyzed after 37 days of planting. The results permit to infer that the irrigation levels exert influence under the studied variables with the higher efficiency of water use found for levels of 75% and 100% of the reference evapotranspiration.
