Bothriochloa ischaemum

Bothriochloa ischaemum

Old world (or Yellow) bluestem

Previous scientific name(s): Dichanthium ischaemum

Warm-season, long-lived perennial bunch grass that occurs on a wide variety of sites but prefers medium to fine textured soils. Highly productive and nutritious, often planted in pure stands for hay production. Also used in pasture and range blends.

Varieties: 
Plains

Productive, persistent, and highly palatable. Desirable in pastures or conservation seedings throughout the short grass plains and into the Southwest. (Released 1970, source of ecotype: Mideast countries)

Ganada

Performs well on a wide range of soil types. Good cold hardiness and drought tolerance. Produces abundant, high quality forage. (Released 1979, source of ecotype: former USSR)

Variety Release Notes: 
WW Iron Master

Later maturing and darker green leaf coor than WW Spar. More robust and leafier than Ganada. Less indeterminate flowering habit than other cultivars. Valuable for forage and soil stabilization on iron-deficient, calcareous soils with high pH. (Released 1976, source of ecotype: Afghanistan)

WW Spar

Winter-hardy, persistent and more drought tolerant than earlier releases. Greens up early and produces abundant forage even under low moisture conditions. (Released 1982, source of ecotype: A single strain selection for the Mideast)
