Abstract/Contents:"Many new bentgrass and bermudagrass cultivars have been commercialized in the last few years, however, there is a lack of research data on their performance under intensively managed putting green conditions. This projected evaluates these grasses on golf course putting or chipping greens built to USGA specifications. This research differs from evaluations conducted at university research stations because the greens are used by golfers for practice putting and/or chipping. The evaluation trials are jointly sponsored by the Golf Course Superintendents Association of America (GCSAA), the United States Golf Association (USGA) Green Section and the National Turfgrass Evaluation Program (NTEP). Trial sites are located on golf courses near a land grant university with a turfgrass research program or in a major metropolitan area which is readily accessible to a university turfgrass scientist. Sixteen evaluation trial sites have been established. Bentgrass trials were all seeded in fall 1997, with one exception. Bermudagrass trials were planted using vegetatively propagated material in June 1998. The second progress reports containing 1999 data and management information on this projected were compiled and distributed in June 2000. The two reports can be found on NTEP web site at http://www.ntep.org/onsite/ost.htm. The on-site advisory committee decided again to report data from each location separately and not summarized over all locations, as in standard NTEP reports. Detailed management information was also reported for each site including establishment (date and any problems), mowing (height, frequency, mower type, rollers and groomers used), cultivation (dates and type of aerification, verticutting and topdressing), pesticide and fertilizer regime used (dates, rates and products used) and factors of play (opening and closing date for play, types of spikes allowed, uses of green). The bentgrass entry "Penn A-4" was again the most consistent top-performer having the highest or second highest mean quality rating at twelve sites in 1999. "Century" continued its good performance with quality ratings in the top statistical group at seven sites although this was down from twelve sites in 1998. "Penn A-1" also performed well having the highest mean turfgrass quality ratings at five sites. Stimpmeter readings again showed little or no statistical differences among the cultivars. The site at Murrieta, CA (SCGA Members Club) will most likely be abandoned after this year due to high poa annua populations. The bermudagrasses had their first full growing season in 1999 and several entries performed well. "Mini-Verde" was the most consistent performer by finishing in the top statistical group for mean turfgrass quality at all seven locations. "Champion" and "Tifeagle" were close behind finishing in the top statistical group at five and four locations, respectively. Data collection on genetic color, density, leaf texture, spring greenup, overseeding quality and thatch showed considerable cultivar variability. Also, at one location (Mobile CC), high nematode populations were found to have a significant affect on turfgrass performance."
