Bothriochloa ischaemum 
(Yellow Bluestems)
Old World Bluestems also known as yellow bluestems are medium-tall, long-lived, warm season bunchgrasses introduced from temperate regions of Eurasia and also in the Atlas Mountains of North Africa. Their common name ,"yellow bluestems", comes from the fact that below the nodes, the stems are light yellow. The species has a broad area of adaptation throughout a large portion of the Southern United States, especially Texas, Oklahoma and New Mexico where it supplies dependable grazing and cured forage.
There is a wide variation in plant types within the species, however, most selections provide a very leafy and nutritious forage which can be grazed by livestock or harvested as hay.
Growth begins late in the spring and continues through the summer. Plants usually grow 2 to 4 feet tall depending on available moisture. The leaf blades are less than 1/2 inch wide and approximately 8 to 12 inches long. The leaves flattened at the base,are dark green in color until the plants reach maturity. Because of its habit of growth and exceptional forage production most of the Old World bluestems have shown great potential for revegatation of rangeland or abandoned cultivated land. Seedings should be made on well-prepared, firm seedbed free from weeds. Plant before the normal spring or summer rains are expected. A seeding rate of 2-5 pls pounds per acre at a depth of approximately1/4 inches deep.

Plains is made up of 30 different strains of Old World Bluestems enabling it to withstand various climatic conditions and soil types. Plains can be used on highly variable soil sites because of its adaptive nature. With our planting methods it possible to expect 1-2 tons/acre the first year and 2-4 tons thereafter depending on the location, soil type, rainfall, fertilization, and overall management, which can vary year-to-year.


Caucasian Bluestem is not a yellow bluestem but is still considered part of the old world bluestem family. This variety is a good forage producer. It grows best on loamy or clay-loam soils. It is better in higher rainfall areas, but does not withstand long-term saturated or saline soils.


WW-Spar is a winter hardy, drought tolerant strain selected out of Plains. Spar has excellent early vigor and produces abundant forage even under adverse conditions. Spar is better adapted to sandy soils, than the other yellow bluestems. Its production is comparable to Plains.


WW-B.Dahl is the latest maturing selection with outstanding leaf-to-stem ratio. The leaves are 2-3 times as wide as the other selections, which allows high forage production and palatability. Our hay fields have produced as much as 9 tons/acre. This selection has good drought tolerance and produces well under dryland or irrigated conditions. It is possibly the best selection of Old World bluestems for forage production, but is not as cold tolerant. This selection has good drought tolerance and produces well under dryland or irrigated conditions.
This selection can produce up to twice as much forage than other Old World Bluestems selections. Recommended for areas south of a line running from Lubbock to Texarkana, TX. (B. Dahl has been successful as far north as I-40 in Oklahoma.)


WW-IronMaster was selected for its improved cold-tolerance and adaptability to iron deficient and high PH soils, allowing cattlemen to maximize those acreages. It produces more forage with less chlorosis than other Old World bluestem selections when grown on iron deficient soils. In more fertile soils, Ironmaster can be expected to increase production at least 20% above Plains and Spar, it also exceeds them in digestibility, leaf-to-stem ratio, protein content, and stocking rates. It matures later than Plains and Spar, providing a longer period of quality forage. Our hay fields have consistently produced over 5 tons/acre. WW-Iron Master is a valuable grass for beef production when used in improved pastures or rangeland plantings. It is also useful for soil stabilization and wildlife cover on iron deficient and marginal farmlands. WW-Iron Master is adapted throughout Oklahoma, Kansas, Texas, New Mexico and Arkansas.
