A study was conducted to compare the effect of nitrogen fertilization (0, 75, 150, 225 Kg N/Ha) on dry matter yields and chemical composition of three tropical grasses: Guinea grass (Panicum maximum), Setaria nandi and Setaria kazungula. The utilization of nitrogen fertilizer caused a significant increase (P<.01) in dry matter yields of the three grasses. There were no significant differences in dry matter yields among grasses; however, the Setaria varieties responded better to nitrogen fertilization than the Guinea grass did. Guinea grass had the highest (P<.01) crude protein and magnesium content, but the Setaria varieties had a higher potassium content than the Guinea grass (P<.01). Nitrogen fertilization had no effect (P>.01) in the crude protein, phosphorous, potassium and magnesium content of the Tropical grasses.
