Psathyrostachys juncea* (Russian wildrye)

Formerly Elymus junceus. Cool season, perennial bunchgrass with an extensive horizontal root system. Adapted a wide range of soil textures and infertile soils; moderately saline and alkaline tolerant. Very drought tolerant, surviving with as little as 8 in. annual precipitation. Cold hardy. May be difficult to establish, but extremely competitive and long-lived thereafter. Starts growth in early spring, produces abundant green basal leave forage. Excellent palatability and can be grazed from late summer through winter, retaining its protein content even when cured. Tolerant of heavy grazing and regrows quickly. Most of the forage sits low in the basal leaves; unsuited for hay production. Use also for arid rangelands, dryland pasture, green strips and fuel breaks. Varieties listed below.

VARIETIES

Boizoisky Select - Good seedling vigor, stand establishment and forage yield. (Released 1984)

Boizoisky II - Selected for seedling vigor, seed mass, seed yield, vegetative vigor, forage production and response to drought. Equal to or greater seedling establishment than earlier varieties. Better seedling establishment than Bozoisky-Select. (Released 2006)
