Resumo

This study aimed to evaluate the chemical composition of Panicum maximum Jacq. cv. Mombaça. Grassland was fertilized with 140 kg ha-1 of P2O5 from different phosphorus sources on grazing, in December, 2002, until April, 2003, with a collection interval of every 28 days. Treatments: 1-Yoorin® magnesium thermophosphate; 2-Gafsa® natural phosphate; 3-simple superphosphate + triple superphosphate (SS + TS) and 4-control. Leaf (lCP) and stem (sCP) crude protein, acid detergent fiber nitrogen (ADFN), neutral detergent fiber (NDF), acid detergent fiber (ADF), cellulose (CEL), hemicellulose (HEM), lignin (LIG), ether extract (EE), calcium (Ca), phosphorus (P), ash (A) and non-structural carbohydrates (NSC) were not influenced by phosphated fertilization. The variables sCP, lNDF, sNDF, sLIG, lLIG, sCEL, lCEL, lADFN, sEE, lEE, lCa, sCa, lP, sP, sA and sNSC, showed some effects from the collection period. There was no difference in the chemical composition of forage of the grass-Mombaça in function of phosphorus sources used in the pasture. The qualitative variations were of low magnitude.
