The distribution of treatments is performed by an Experiment nested of Block Design Completely Random in a settlement of plots divided. The results reported that the best performance is obtained by applying the treatment of urea to 15 days after cutting in three copies of the test, with a green forage production, dry matter, plant height and benefit cost of 9,90, 17,67 and 18,50 Tn/ha/ cut dry matter, 52,62, 54,21 and 57,54 cm of the plant height and 23,97 and 114% of profitability in the first second and third repeat respectively.
