Synopsis Napiergrass, guineagrass, and paragrass responded strongly to annual applications of up to 800 pounds of nitrogen per acre. Protein content and protein yields increased up to the highest N level tested. Yields increased but quality of the forage decreased with length of harvest interval. Between 30,000 and 45,000 pounds of dry matter averaging about 9.5% protein were produced annually per acre.
