Phenology and Forage Production of Cool Season Grasses in the Southern Plains

Abstract

Thirteen varieties of cool season grasses were tested under dryland and irrigated conditions in the Southern High Plains. All introduced varieties out-produced the two native species. Peak percent of forage protein content corresponded with peak growth periods. Sandia orchardgrass and NM-384 tall fescue were the most productive varieties under irrigation but did not survive limited irrigation. Luna pubescent wheatgrass and largo tall wheatgrass were the most resistant to limited moisture conditions and are recommended for irrigated, cool season forage planting.
