Interpretive Summary: Haymaker intermediate wheatgrass is a broadly adapted cultivar that produces high, stable forage yields when used for cool-season grass hay production or for pastures in the tall, mid-grass and short-grass eco-regions of the Central and Northern Great Plains. It was released in April, 2003 by the USDA, Agricultural Research Service; Agricultural Research Division, Institute of Agricultural and Natural Resources, University of Nebraska; and the USDA, Natural Resources Conservation Service. Haymaker had the greatest average forage yields at both the central and northern Great Plains sites when compared with released cultivars and other experimental strains of intermediate wheatgrass. The forage quality of Haymaker as measured by forage digestibility and protein concentration is less than that of 'Beefmaker' but is similar to that of other released cultivars of intermediate wheatgrass. It will be recommended for dryland hay production in the Central and Northern Great Plains, USA in USDA Plant Hardiness Zones 3, 4, and 5.
