Growth Characteristics of Crested and Fairway Wheatgrasses in Southern Idaho

Abstract

Crested and fairway wheatgrasses have been growing together and spreading in southern Idaho for over 30 years and are well-adapted to Idaho. We found that fairway produces only 79% as much herbage as crested, but that it had spread 112% further by seed and is grazed more uniformly. Both species spread more in eastern than in southwestern Idaho.
