Cool-season grass mixtures and warm-season grass mixtures were evaluated in 2010, 2011, and 2012 under varying irrigation levels to determine dry matter yield, CP, and TDN for beef cattle in the Nebraska Panhandle. As a generalization, when seasonal precipitation was average, irrigation levels over 10 inches resulted in no significant increase in either grass production or quality. Cool-season grasses produced more dry matter yield and maintained greater CP and TDN than warm-season grasses. In all three years, a mixture of wheatgrasses had greater forage yield than an orchardgrass monoculture or a mixture dominated by bromegrasses. In 2010 and 2011, treatments containing switchgrass yielded more DM than a big bluestem/indiangrass mixture.
