This work evaluated the productivity of dry matter and crude protein in Pennisetum purpureum cv Napier pasture fertilized with poultry litter to replace chemical fertilizers. The area used was a grazing Pennisetum purpureum cv Napier planted in line on a sandy soil. The area used for the plots was of approximately 800 m2 , divided into five blocks with three portions of 6x7 m. Samples were collected every 42 days during one year. The treatments were: T1 - 20 tonnes of poultry litter per hectare applied only once, 30 days before the first grazing cycle (Instruction No. 15 and No. 8 - MAP); T2 - 20 tonnes of poultry litter per hectare divided into 5 applications during summer grazing (4 tons per application); and T3 - 70 kg nitrogen (N) per hectare (approximately 150 kg of urea). Morphological and strata separations were carried out during the experimental period, which was conducted in a completely randomized block design (5 blocks of 3 plots per block). Results showed no differences in dry matter production, morphology, strata and crude protein levels among treatments. Therefore, the use of poultry litter as an organic fertilizer in elephant grass pastures is feasible since it generates the same levels of productivity and quality than urea fertilization.
