Abstract: Appropriate nitrogen fertilization rates are required to establish and maintain native grasses. A two-year experiment was conducted to determine about ground dry matter production and nitrogen accumulation at five levels of nitrogen fertilization with ammonium nitrate. The experiment was a randomized complete block design with four replications. Forages consisted of one perennial, eastern gamagrass, and two annuals, crabgrass and sorghum-sudangrass. The five nitrogen rates (0, 112, 224, 336, 448 kg ha-1) were applied three to four times from to August. In both years, the unirrigated site did not ensure optimal establishment of annual grasses and gamagrasses provided more reliable yields early in the season. Higher nitrogen rates produced greater dry matter production and nitrogen uptake. Data from both years will be summarized and apparent nitrogen recovery values will be presented.
