Abstract

 The turf density and color are important factors affecting turf quality. These factors plus shoot/root ratio, would increase attractiveness, photosynthesis and wear tolerance and would decrease damages from the athletics falling on the sport fields. Bermuda grass would lose its quality in the cool seasons, because of its dormancy period. To study the effects of urea on turf quality, a spilt plot experiment was conducted using a complete randomized blocks design with three replications in dormancy period, during 2002-2003 at Horticultural Department of Shahid Chamran University. Four nitrogen levels (control, 3, 5, 7 g m-2 as urea) and 3 time intervals between urea spraying, (15, 30 and 45 days) were examined. The results showed that nitrogen treatments reduced winter dormancy duration and increased the quality of the lawn in comparison with control. According to the results obtained from chlorophyll meter, the treatments of 3 and 5 g m-2 and time intervals of 45 days increased the leaf green color. In the warm and sunny weather, treatments with higher nitrogen levels and long time intervals improved the turf density. A proper ratio of root/shoot (3: 1) wase obtained using 3 g m-2, with time interval of 45 days. This treatment was considered the best treatment for turf management in south of Iran.
