Abstract: Forage yields of Dominant winter rye clipped in the spring in a series of 12 treatments ranged from about [Formula: see text] ton to over 2 tons of D.M./acre. Clipping reduced grain yields by at least 10% and several clipping treatments prevented any grain production. The lowest forage yield and the least reduction in grain yield resulted from a single early clipping. Forage yield increased by [Formula: see text] ton D.M./acre for each week’s delay in clipping with correspondingly greater reduction in grain yield. Crude protein content of the forage decreased from 25 to 13% in a 3-week period. Increased forage yields were obtained when the interval between repeated clipping was increased from 1 to 2, 3, or 4 weeks. Protein levels were maintained at over 25% for 3 months with weekly clipping. Height, maturity, and ergot incidence were adversely affected by all clipping treatments.
