Bluestem (Yellow Ganada)
Yellow Bluestem is a medium-tall, introduced, long-lived, warm-season bunchgrass. Its common name "Yellow Bluestem" comes from the fact that below the nodes, the stems are light yellow, grading into pale green during the growing season.
The species has a broad, natural geographic distribution, and is found throughout the subtropical and temperate regions of Eurasia and also in the Atlas Mountains of North Africa.
There is a wide variation in types of plants within the species, some being quite coarse with few leaves and low in forage production, and others that are much less coarse, leafy, and are good forage producers. Certain strains and varieties of Yellow Bluestem are quite acceptable to livestock. Plant when the normal spring or summer rains are expected to occur. Seed should be planted to a depth of 0.6 to 1.3 cm (¼ to ½ in.).

The Agricultural Experiment Stations of New Mexico, Colorado, and Arizona, and the USDA Soil Conservation Service released Ganada Yellow Bluestem in 1980. Ganada seed was collected near Tajikistan, Turkey in 1934 by the Westover-Enlow Expedition. It is adaptable to a wide range of soils throughout New Mexico and Colorado.
Ganada is a valuable soil stabilizer for critical areas and for revegetation of deteriorated rangeland. In favorable years it spreads aggressively by volunteer seedlings. It has been observed that forage of Ganada was very well accepted by livestock.
King Ranch Bluestem
The original King Ranch Bluestem seed was collected near Amoy, China in 1917. The cultivars in its present form traces back to plants found growing on the King Ranch in 1937. It is adapted to medium and fine-textured soils. King Ranch Bluestem is productive and persistent in the southern half of Texas and is able to withstand winter temperatures as far north as central Oklahoma.
Plains Yellow Bluestem was released in 1970, by the Oklahoma Agricultural Experiment Station and the Plant Science Research Division, Agricultural Research Station. Source materials in Plains trace to plant introductions from Pakistan, Iran, Iraq, India, Turkey and Afghanistan. In its area of adaptation, Plains has been considerably more productive and persistent than the King Ranch variety. It is readily accepted by livestock and has been preferred over Caucasian Bluestem.
Plains grass is well suited for use both as pasture and conservation grass in the Southwest and should be particularly adaptable for seeding of depleted rangelands in the western half of Oklahoma.
WW Spar Bluestem
WW Spar was released in 1982 by the USDA Agricultural Research service Southern Plains Range Research Station, Woodward, Oklahoma and the Oklahoma Agricultural Experiment Station. WW Spar was produced from a single strain, which was one of the 30 strains comprising Plains Bluestem. It is winter hardy and has excellent persistence throughout Oklahoma and into Kansas. WW Spar has greater drought tolerance than Plains or Caucasian, has an earlier spring green-up and produces more forage under drought conditions than other components of Plains.
WW Iron Master Bluestem
(Same basic attributes as WW Spar with improved adaptation to alkaline soils.)
