| Abstract/Contents: | "New ultradwarf bermudagrasses have the promise of providing improved putting performance for golf courses in warm climates. Comparative documentation of ultradwarf performance under an array of management conditions and environments is needed to identify optimum strategies for these grasses. Three ultradwarfs (‘Tifeagle’, ‘Champion’, and ‘Floradwarf’) were compared for turfgrass quality over a four-year period (2000-2003) in subtropical south Florida. The effect of nitrogen rate was also evaluated. Research findings include: All turfgrasses provided annual average turfgrass quality ratings above that judged to be minimally acceptable. There were significant differences in the annual average turfgrass quality of the three bermudagrasses. ‘Tifeagle’ had the highest annual average turfgrass quality ratings and in three of the four years, was significantly higher than the other two grasses evaluated in the experiment. ‘Champion’ had an annual average turfgrass quality rating equal to ‘Tifeagle’ in year 1. Thereafter, it was lower than ‘Tifeagle’ in annual average turfgrass quality. ‘Floradwarf’ annual average turfgrass quality was lowest in year 1. In year 2 and 4, ‘Floradwarf’ annual average turfgrass quality was equal to ‘Champion’ and in year 3 was better than ‘Champion’. Turfgrass quality was generally increased with increasing rate of nitrogen to 18 lbs N per 1000 sq. ft. per year. No additional increases in annual turfgrass quality were observed with higher N rates and in year 2, annual average turfgrass quality was reduced at the 24 lb N per 1000 sq. ft. rate of application. Turfgrasses in subtropical south Florida have a yearround growth cycle and intense rains which reflects higher annualized N rates. Ultradwarfs can provide acceptable quality turf for warm season putting greens in subtropical conditions." |
