Abstract

The effect of phosphorus levels (0, 50, 100, 200 and 300 mg/dm3 of P) on dry matter (DM) yield and chemical composition of Panicum maximum var. Massai, was evaluated under greenhouse conditions. P fertilization significantly increased DM yields and nitrogen, and phosphorus contents, however did not affect (P>.05) calcium, magnesium and potassium contents. Maximum DM yield and crude protein, and phosphorus contents were obtained with the application of 197.2; 105.5 and 246.7 mg/dm3 of P, respectively. Internal phosphorus requirement for 80% maximum DM yield was estimated at 0.227%, corresponding to application of 175.5 mg/dm3 of P. The phosphorus efficiency utilization was inversely proportional to phosphorus levels
