Abstract
At elevations higher than 6000 ft., grasses are one of the better options available for producers to optimize potential forage production. This study evaluates grass species intermediate wheatgrass (Rush), meadow brome (Regar), orchardgrass (Potomac II), perennial ryegrass (Journey), tall fescue (Teton), and tall wheatgrass (Alkar) grown at 6,120 ft. high elevation for dry-matter yield (DMY) and quality during the establishment year (2017), and 2018 and 2019 under irrigation. Higher yielding grasses such as tall fescue and tall wheatgrass produced lower RFQ values, while lower yielding grasses such as perennial ryegrass produced higher RFQ values.
