摘要: INTRODUCTION The recent great drought covering the plains area has caused a change in type of grassland research. A realization importance conservation our soil and native plants been brought clearly before research workers as well entire population. Overgrazing, depletion moisture, continued tilling pulverized soil, resultant blowing dust an enormous reduction plant cover. Any one these factors would have resulted serious damage, taken together they literally cost people region millions dollars. New methods into use with them come need for hardy binding which can be easily established on disturbed soil. These conditions to turn their attention toward finding revegetate stricken areas get established. Quadrat studies, general observations, show that side-oats grama grass (Bouteloua curtipendula) is more resistant than its associate, little bluestem (Andropogon scoparius). Before draught covered hillsides mixed prairie association; at present time, however, it almost completely replaced by (Albertson, 1938). This indicates may possibilities revegetation purposes. It widely adapted shown 'by widespread distribution much territory any other grasses (Hoover, 1939). Side-oats good forage producer shows capabilities improvement selection crossing. species (Bouteloua) might make favorable domestication (Range Plant Handbook, 1937). rhizomatous nature tough fibrous root system makes binder, spite fact not sod former. Its habit growing slightly favored spots suggests this excellent roadside ditches, dam spillways, terrace outlets, etc. study, period two years, was originated order learn merits faults Great Plains region. suggested there definite knowledge about are potential Plains. An attempt made find many growth habits possible, comparison growth, development, production
