| Abstract/Contents: | "With the initiation of on-site testing of bentgrass and bermudagrass on putting greens, interest is now increasing for the evaluation of other grasses used on golf courses. Grasses are needed that provide exceptional playing surfaces with less pesticides, fertilizer and water. Therefore, grasses that have superior drought, cold, heat, disease and insect resistance need to be identified. Overseeding bermudagrass fairways is a common practice throughout the southern half of the United States. Millions of pounds of seed are bought and sown each autumn on golf courses in this region. Golf course owners, managers and superintendents seek grasses that establish quickly, exhibit exceptional playability, are aesthetically pleasing and require less inputs. This project will evaluate new cultivars on bermudagrass fairways at golf courses in the Southern and Western U.S. This on-site testing program will provide specific information of a more applied nature about cultivars for overseeding. The evaluation trials are jointly sponsored by the Golf Course Superintendents Association of America (GCSAA), the United State Golf Association (USGA) Green Section and the National Turfgrass Evaluation Program (NTEP). Ten evaluation trial sites were chosen. Trials are positioned strategically in the following areas: southern California, Arizona, Houston, TX, Dallas, TX, Mississippi, central Florida, Myrtle Beach, SC, Virginia, Atlanta, GA, and St. Louis, MO. Trials are conducted with named cultivars and commercially available blends or mixtures. The trials are located on active play sites were golfers hit fairway golf shots and/or drive golf carts. Plot size is large, 5'x 20', replicated three times. Data from 1999-2000 was compiled and published via hard copy and on NTEP web site (www.ntep.org/onsite/ost.htm). Variety performance varied from location to location, however, general trends emerged. The perennial ryegrass entries, in general, provided the highest quality turf averaged over the entire season. The poa trivialis entries and perennial ryegrass/poa trivialis mixtures were slower to establish and lighter green in color. This reduced their quality ratings at most locations, but at two locations, other factors such as decuded poa annua invasion, put the poa trivialis entries on top. Turfgrass quality ratings averaged over the entire season, yielded small levels of significance at most locations. In other words, at most sites, one-half to two-thirds of the entries performed statistically similar to the top entry. The data does, however, reveal differences in spring transition from the overseeding grass to bermudagrass. The annual ryegrass and intermediate ryegrass entries transitioned faster than the most all perennial ryegrass entries. At some sites, the entries that contain poa trivialis transitioned back to bermuda faster than perennial ryegrass. At other sites, the opposite was true, the perennial ryegrasses disappeared quicker in spring than poa trivialis. At a couple of other locations, the poa trivialis and perennial ryegrass entries transitioned in a similar manner. This leads us to believe that this transition phenomenon is highly weather-related." |
