The effects of phosphorus sources (Yoorin, simple superphosphate (SS) + triple superphosphate (TS)) of fertilizers of Mombaçagrass (Panicum maximum Jacq. cv. Mombaça) pasture were evaluated on the death and senescent material, litter production, and concentration and amount of minerals (N, P, K, Ca, and Mg) in the pasture, under grazing. The experiment was carried out from December/2003 to April/2004. The grazing method was the continuous stocking and variable stocking rate, and the animals were crossbred. The design was a randomized complete block with three replications. The phosphorus source did not have significant effect on the death and senescent material and litter production, but the death material production ranged from 4,521 to 5,097kg ha-1. The phosphorus source did not have significant effect on the amount and concentration of N, K, Ca, and Mg. However, the phosphorus amount and concentration were different, influenced by the phosphorous source, ranging from 2,16 to 5,04kg ha-1 and 0,52 to 1,01gkg-1, respectively. The use of the phosphorus sources did not change the litter, senescent and death production, and the concentration and amount of minerals in the death material.
