Midwestern golf course superintendents have come to realize that un-mowed roughs often reduce labor, fuel, and pest-control chemical expenses compared to mowed areas that receive more intense management. Moreover, interest has developed in identifying grasses for un-mowed roughs that are also playable. In two studies initiated in June 2006, this research is examining seeding rates for common blue grama (Bouteloua gracilis) and several blue grama cultivars, alone, and mixed with buffalograss (Buchloe dactyloides) to determine if these grasses are suited to producing un-mowed, playable roughs in the Midwest. In the seeding rate study, we planted plots of common blue grama in Urbana, Illinois, USA at seeding rates of 10, 15, 20, 25, and 30 pounds (PLS) per acre. Results of this study show that 20 pounds (PLS) per acre was an appropriate seeding rate. We also planted plots of Alma, Bad River, common, Hachita, and Lovington blue grama grasses alone, and combined with Cody buffalograss, as well as a plot of Cody buffalograss. The single blue grama cultivar plots were seeded at 20 pounds (PLS) per acre, the combined plots were seeded at 10 pounds (PLS) blue grama seed plus 44 pounds buffalograss (PLS) per acre, and the Cody buffalograss was seeded at 88 pounds (PLS) per acre. In September, the plots containing Lovington blue grama, Alma blue grama plus Cody buffalograss, Lovington blue grama plus Cody buffalograss, and Hachita blue grama + Cody buffalograss had significantly greater percent cover than the other plots. We will repeat both studies in 2007.
