The effect of nitrogen fertilization and cutting management on the yield and nitrogen content of two sudangrass varieties and two millet species

The study reported here was designed to determine the combined effects of three nitrogen fertilization levels and four cutting intensities on the forage yields and nitrogen content of four summer annual grasses. The grasses used in this study were: Sweet Sudangrass, a variety developed through hybridizing Leoti sorghum and common Sudangrass, Piper Sudangrass, a variety developed from a double-cross of Tift Sudangrass and lines obtained from the Texas Agricultural Experiment Station and Kansas Agricultural stramineofructa Bailey; and Georgia hybrid No. 1, an experimental variety of Pearlmillet, produced from four inbred lines at the Georgia Coastal Plain Experiment Station, Tifton, by G. W. Burton, Principal Geneticist, U. S. Department of Agriculture.
