As temperatures drop during autumn and winter, their growth stop and turn yellow - brown when minimum air temperatures fall below about 10ºC. They use less water than cool-season grasses. This superior drought tolerance is stimulated interest in warm-season grasses in the cooler regions as well as in subtropical and tropical regions. Field experiments were carried out on turf research plots at Uludag University Research Farm, Bursa. The experimental design was a split-split plot with turfgrass species as a whole plot, irrigation levels as the sub plots and fertilization levels as the sub sub plots. Whole plots consist of four warm season turfgrass species, hybrid Bermudagrass (Cynodon transvaalensis x Cynodon dactylon), seashore paspalum (Paspalum vaginatum Sw.), zoysiagrass (Zoysia japonica Steud.) and St. Augustine grass (Stenotaphrum secundatum (Walter) Kuntze) and two cool season turfgrass species, perennial ryegrass (Lolium perenne L.) and tall fescue (Festuca arundinacea Schreb.). Irrigation levels are subplots and fertilization regimes are sub-sup plots in this experiment. The turfgrasses were evaluated at irrigation levels of 25, 50, 75 and 100% actual evapotranspratation and at nitrogen fertilization regimes of 0, 1.25, 2.5 and 5.0 g N m-2 month-1. Turf color and quality of each plot were rated visually and clipping weight were determined. Keywords : Turfgrases, nitrogen, irrigation, turf quality, turf color
