Interpretive Summary: Seeding perennial cool-season grasses can be used to extend grazing seasons on rangelands. We evaluated yearling livestock performance and stand persistence of three released varieties of wheatgrasses seeded in the Northern Great Plains. We found livestock performance grazing these pastures in spring varied among the varieties. Gains were similar in 1997; gains were greater on Hycrest than Rosana in 1998; and gains were greater on Hycrest and Rosana than Luna in 1999. In 1 out of 3 years Hycrest crested wheatgrass provided more forage than Rosana western wheatgrass and would have allowed an increase in livestock numbers during spring. We also found that persistence of Luna pubescent wheatgrass is a problem in the 13 inch precipitation zone.
