Abstract/Contents:"Blue grama (Bouteloua gracilis (Willd. ex Kunth) Lag. ex Griffiths (Poaceae)) is a warm-season grass native to the shortgrass prairies throughout Mexico, the United States and Canada where areas can receive less than 300 mm of precipitation annually. This drought tolerance makes blue grama a candidate for low-input use in out-of-play areas on golf courses, roadsides, etc. A 4x2 factorial design study was established to determine optimal planting using four soil temperatures at seeding, 10°C, 15°C, 20°C and 25°C, for two blue grama cultivars, Birds Eye and Hachita. Each planting date had four replications and the study was repeated once at the Turfgrass Research Center in Blacksburg, VA. Plots were seeded at a rate of 98.44 kg · ha-1 after tilling and were initiated with either a natural rainfall event or 6.35 mm of irrigation with no additional inputs thereafter. Canopy coverage was visually assessed weekly. Successful establishment for this experiment was defined as a plot reaching 70% canopy cover. Birds Eye only reached acceptable coverage after 11 weeks when seeded at 15°C, while all other planting temperatures were unsuccessful. Hachita reached coverage above 70% at all four planting dates but only 15°C and 20°C were deemed successful. At three weeks after initiation, the 25°C planting date reached cover of 69% and 78% respectively. However, at subsequent observation dates both cultivars fell below the 70% target and were considered failed plantings. This may be attributed to seedling intolerance to excess soil moisture This experiment suggests that the optimal soil temperature for planting blue grama is 15°C and can be successfully established with minimal inputs."
