Effects of Different Nitrogen Doses on Turf Performance of Tall Fescue (Festuca arundinacea L.) Cultivars

This study was conducted to determine the effects of different nitrogendoses on turf performance of some tall fescue cultivars on agricultural researchand applied center of suleyman demirel university, during 2014‐15 years. thisresearch was conducted in randomized block design with three replications. tallfescue (festuca arundinacea schreb.) cultivars starlet, debussy and rebel wereused in this research. four nitrogen levels (0, 2, 4 and 6 g m2 mount‐1) were appliedin this research. the speed of germination (day), ground cover speed (day), groundcover rate (1‐9 point), leaf texture (1‐9 point), winter endurance (1‐9 point), leafcolor (1‐9 point), regeneration power (1‐5 point), tiller number per dm2, drymatter yield (kg da‐1) and general appearance (1‐9 point), were determined in thisresearch. according to results, debussy cultivar showed the best performance interms of leaf color, regeneration power and dry matter yield. the effects ofnitrogen fertilizer applications on turf performance were significant. increasing nfertilization doses resulted in an increase in winter endurance, ground cover rate,leaf texture, leaf color, regeneration power, tiller number, dry matter yield and general appearance.
