The objective of the experiment was to evaluate the influence of nitrogen fertilization on cutting intervals on the nitrogen and carbohydrate fractions of Momba?a grass (Pannicum maximum Jacq. cv. Momba?a). The treatments were: 0; 200; 400 and 600 Kg of N/ha and cutting intervals of 35 42; and 49 days. It was used ANOVA and linear regression for the statistical analysis. Significant effect of the nitrogen fertilization and the cutting intervals on the quality composition and on had been observed the protein and carbohydrates fractions. The nitrogen fertilization provided to greeters concentrations of non protein nitrogen (NPN) and soluble protein. The best concentration of proteins was obtained with cutting intervals of 35 days with 600 Kg of N/ha. There was an increment of the fractions C of the protein and carbohydrate in function of the cutting interval.
