Indiangrass is a long-lived, warm-season, tall grass native to the Great Plains. It thrives on deep, moist soils ranging from heavy clays to coarse sand. Indiangrass spreads by seed. Individual plants increase
in size to large, dense bunches of short, scaly underground rhizomes. Normally it is not found as a dominant species, but it is considered a valuable grass and should be used in reseeding on range sites, where it is listed as an important decreaser.
The seed is chaffy, and a special drill is needed for planting. Drill seed between 0.6 to 1.9 em (V4 to 3f4 in.) deep or broadcast and cover lightly. Planting dates are normally January to April in the southern Great Plains and April to May in the northern Great Plains. Seed mulch may be needed on steep, erosive sites or disturbed lands.

A fine-leafed variety recommended for parts of the Texas Panhandle and the adjoining states.
Llano indian grass was released in 1963 by the New Mexico State University Agricultural Experiment Station and USDA Soil Conservation Service. The original seed was collected from sandy plains sites near Hudson and Portales, New Mexico, elevation 1220 m (4,000 ft.}. Llano has good seedling vigor, forage production and seed production.
Disease and insects have not been a problem in the production of Llano indiangrass under cultivation or in range plantings. It may also be used as a warm-season, irrigated pasture grass, as it is capable of producing good yields of high quality forage or hay. Llano is well-adapted to sandy plains sites and deep sand sites of the southwestern Great Plains where annual precipitation is 41 ern (16 in.) or more. Plantings in eastern New
Mexico and east-central and southeastern Colorado have given good results.
Lometa indian grass is an indiangrass selection released in 1981 by the USDA Soil Conservation Service in Texas in cooperation with the USDA Agricultural Research Service and the Texas Agricultural Experiment Station. Lometa came from a collection made from a native indian grass stand on the Kirby Ranch in Lampasas County in central Texas.
Lometa is adapted to most soils in Texas in areas with normal precipitation of at least 56 em (22 in.) per year. Areas west of this area should either be irrigated or receive additional water from runoff or overflow.
Flowering occurs approximately 2 to 4 weeks later than other presently available commercial indiangrass, thus extending quality grazing over a longer period. Lometa has proven. to be a more adaptable, longer-lived and more productive indiangrass in Texas, especially in the central and southern areas. Seeding rate is 5.6 kg PLS/hectare (5 PLS lbs./acre) broadcast or drilled.
Osage indian grass was released in 1966, cooperatively by the Kansas Agricultural Experiment Station.ithe USDA Soil Con- servation Service and the Agricultural Research Service. The original seed sources were from collections made in eastern and central Kansas and Oklahoma. A southern type from Kansas was adapted for use in parts of central Kansas, western Oklahoma, the central, rolling red plains of Texasand eastward.
