Establishment of Russian Wildrye on Foothill Ranges in Utah

Abstract

Seedings of Russian wildrye were made in Tintic Valley, Utah, to determine the effects of seeding method, seeding rate, season of planting, and seed type on stand establishment. After 3 years, more plants were established by commercial seed than by seeds of the improved Vinall strain. Initially the 12-pound rate of seeding established more plants than either the 6 or 9 pound rate, and drilling established more plants than broadcast seeding. However, by the third year little difference among seeding methods was evident. Use of a heavy seeding rate of 24 lb/acre in an attempt to have viable seed in the soil for more than one growing season was a failure.
