Russian wildrye (Psathyrostachys junceus, previously known as Elymus junceus) is a cool season perennial bunchgrass introduced from Siberia. It is long-lived and adapted to semiarid climates. It is used extensively for late summer/fall grazing. It has poor seedling vigor and is slow to establish, but is very competitive once in a stand.
RUSSIAN WILDRYE HABITAT:
Russian wildrye is most easily established and is most productive on loam and clay loam soils. It is very productive in seep areas and tolerates moderate salinity. Extensively used in the western US and Canada.
RUSSIAN WILDRYE USES:
Russian Wildrye is an excellent restorative species for rangeland, CRP, erosion control. It is an excellent component of dryland pasture mixtures and is well adapted to that use. It maintains its forage quality even when mature. It makes much better summer and fall pasture than crested wheatgrass. It can be grazed late into the fall and winter.
Russian wildrye is a cool-season grass and most of its production is during the months of April, May and June. This usually coincides with the best soil water conditions. The forage is very palatable. It can be grazed at any time of the year from April until December or later depending on available forage and weather. It is very tolerant of grazing and regrows quickly. It has good tolerance to salinity and we frequently recommend it as a mix component for that purpose.
RUSSIAN WILDRYE CULTIVARS:
Swift: selected by Agr. Canada Research Station, Lethbridge, Alberta, Canada for better seedling emergence and good resistance to leaf spot. It was released in 1978.
Bozoisky-Select: selected by USDA ARS at Logan, Utah for improved seedling vigor and increased forage yield. It was released in 1984 and has shown good seedling performance.
Bozoisky II: developed by USDA ARS at Logan, Utah and selected for seedling vigor (emergence from a deep planting depth), seed mass, seed yield, vegetative vigor, total dry matter production and response to drought. It is a broad-based 15 clone synthetic that is much broader than other releases. It was released in 2004.
