Effects of Different Nitrogen Doses on The Turf Performance of Perennial Ryegrass (Lolium perenne L.) Cultivars
Abstract
This study was conducted to determine the effects of different nitrogen doses applications
on turf performance of some perennial ryegrass cultivars in Agricultural Research and Applied Center
of Suleyman Demirel University in Turkey, during 2014-15 years. The research was conducted in
randomized block design with three replications. Three perennial ryegrass cultivars; Cutter, Troya and
Stravinsky were used with four nitrogen levels (0, 2, 4 and 6 g m2 mount-1
) applied in this research. At
the end of the study, speed of germination (day), ground cover speed (day), ground cover rate (1-9
point), leaf texture (1-9 point), winter endurance (1-9 point), leaf color (1-9 point), regeneration power
(1-5 point), tiller number per dm2
, dry matter yield (kg ha-1
) and general appearance (1-9 point) were
determined. According to results, Cutter and Stravinsky cultivars showed the best performance in
terms of speed of emergence, leaf color, regeneration power and infrequency degree. The best
performances in terms of ground cover speed, tiller number, dry matter yield and nitrogen content
were observed from Stravinsky cultivar. Cutter showed the best performance in terms of general
appearance among the cultivars. Nitrogen applications have effected the turf performance
significantly. Increasing N fertilization doses increased the cold tolerance, ground cover rate, leaf
color, regeneration power, tiller number, general appearance, dry matter yield and nitrogen contents of
cultivars.
