Abstract
Synopsis: Annual forage yields increased as the interval between cuttings increased to 6 weeks, leveled off as the interval increased to 12 weeks and dropped sharply in plots cut only once. Increasing the interval decreased crude protein and vitamin A equivalent content, leaf percent, and in vitro digestibility and increased stem length and fiber content. Increasing N applications increased yields of dry matter and crude protein and the content of crude protein and vitamin A equivalent but had no effect on the percent fiber in the grass.
