Interpretive Summary: ABSTRACT ONLY

Technical Abstract: Winter wheat pasture provides economical, high-quality forage for livestock during a time few other grazable forages are available. Despite increased use of white wheat little is known about the forage. This experiment examined forage yield and quality of six hard red (2137, Jagalene, Jagger, OK101, Stanton, and Thunderbolt) and six hard white (Burchett, Lakin, NuFrontier, NuHills, NuHorizon, and Trego) wheat varieties. Each variety was planted in four replicated plots in the southwest Kansas counties Clark and Stanton. Forage was harvested from the same 6 ft of row in Dec, Mar, or Apr/May to simulate grazing during the fall/winter, prior to jointing, and graze-out, respectively. Forage yields appeared highest in Dec at Clark, while they appeared highest in May at Stanton. Yield differed among varieties at all harvests in Stanton, but only for the Apr harvest at Clark. Crude protein (CP) differed among varieties at all harvests except in Mar at Clark. Dec and Mar CP were well above requirements for stocker calves. The simulated Apr/May graze-out harvests had lower CP with Clark marginal for maximum stocker gain. Variety differences occurred for acid detergent and neutral detergent fiber in four of the six harvests. Only the Apr harvest at Clark appeared to have marginal energy levels for calf gain, similar to the CP results. Nitrate-N differed among varieties for the Dec and Mar harvests at Stanton, and between red and white wheat varieties for the Dec cutting. Forage traits appeared to be more closely related to individual varieties, since there were few statistical differences associated with wheat class.
