AB  - This research was conducted at Burdur Mehmet Akif Ersoy University between 2020 and 2022 years with the aim of determining the effects of different nitrogen doses on some cool-season turfgrass mixtures commonly used on football fields. In the study, eight different turfgrass mixtures were created using Lolium perenne, Festuca arundinacea, Festuca rubra var. commutata, and Poa pratensis, and five different nitrogen doses (0, 2, 4, 6, and 8 g m-2) were applied. In the research, parameters such as emergence speed, ground cover speed, winter resistance, ground cover rate, leaf texture, leaf color, regeneration power, tiller number, overall appearance, clipping yield, and nitrogen ratio were determined. According to the variance analysis results, both turf mixtures and nitrogen doses had statistically significant effects on all of the characteristics examined in the research. Depending on the mixtures, emergence speed ranged from 12.33 to 16.73 days, ground cover speed ranged from 23.80 to 28.13 days, winter resistance ranged from 5.13 to 7.13 points, ground cover rate ranged from 5.53 to 7.67 points, leaf texture ranged from 1.86 to 2.86 mm, leaf color ranged from 2.20 to 7.23 points, regeneration power ranged from 2.00 to 3.73 points, tiller number ranged from 185.40 to 268.93 per dm2, overall appearance ranged from 3.17 to 7.67 points, clipping yield ranged from 595.19 to 925.87 g m-2, and nitrogen ratio ranged from 1.71% to 2.14%. Mixtures such as 50% L. perenne + 50% F. arundinacea, 25% L. perenne + 50% F. arundinacea + 25% F. rubra var. commutata, and 40% L. perenne + 30% F. arundinacea + 30% P. pratensis exhibited superior characteristics. In the research, as nitrogen doses increased, winter resistance, ground cover rate, leaf texture, leaf color, regeneration power, tiller number, overall appearance, clipping yield, and nitrogen ratio in plant tissues showed increases. According to the results, in football fields to be established in Burdur province and similar ecological conditions, turfgrass mixtures with a high proportion of F. arundinacea and L. perenne species should be preferred, and a monthly nitrogen application of 6 g m-2 should be regularly applied.

N2  - Bu araştırma 2020-2022 yıllarında, futbol sahalarında yaygın olarak kullanılan serin mevsim çim türlerinden oluşturulmuş bazı karışımlar üzerine farklı azot dozlarının etkilerinin belirlenmesi amacıyla Burdur Mehmet Akif Ersoy Üniversitesi’nde yürütülmüştür. Araştırmada Lolium perenne, Festuca arundinacea, Festuca rubra var. commutata ve Poa pratensis türleriyle oluşturulan 8 farklı çim karışımına beş farklı azot dozu (0, 2, 4, 6 ve 8 g m-2) uygulanmıştır. Araştırmada; çıkış hızı (gün), kaplama hızı (gün), kışa dayanıklılık (1-9), kaplama derecesi (1-9), yaprak dokusu (mm), yaprak rengi (1-9), yenilenme gücü (1-5), kardeş sayısı (adet/dm2), genel görünüm (1-9), kuru madde verimi (g m2) ve azot oranı (%) belirlenmiştir. Varyans analiz sonuçlarına göre, çim karışımları ve azot dozları araştırmada incelenen tüm özellikler üzerine istatistiki olarak önemli etki yapmıştır. Karışımlara göre, çıkış hızı 12.33-16.73 gün, kaplama hızı 23.80-28.13 gün, kışa dayanıklılık 5.13-7.13 puan, kaplama derecesi 5.53-7.67 puan, yaprak dokusu 1.86-2.86 mm, yaprak rengi 2.20-7.23 puan, yenilenme gücü 2.00-3.73 puan, kardeş sayısı 185.40-268.93 adet, genel görünüm 3.17-7.67 puan, kuru madde verimi 595.19-925.87 g m-2, azot oranı %1.71-2.14 arasında değişmiştir. %50 L. perenne+%50 F. arundinacea, %25 L. perenne+%50 F. arundinacea+%25 F. rubra var. commutata ve %40 L.perenne +%30 F. arundinacea+%30 P. pratensis karışımları daha üstün özelliklere sahip olmuşlardır. Araştırmada azot dozlarının artmasıyla kışa dayanıklılık, kaplama derecesi, yaprak dokusu, yaprak rengi, yenilenme gücü, kardeş sayısı, genel görünüm, kuru madde verimi ve bitki dokularındaki azot içeriklerinde artışlar görülmüştür. Sonuçlara göre araştırmanın yürütüldüğü Burdur ili ve benzer ekolojik koşullarda oluşturulacak futbol sahalarında özellikle F. arundinacea ve L. perenne türlerinin fazla oranlarda bulunduğu çim karışımları tercih edilmeli ve aylık düzenli olarak 6 g m-2 azot uygulanmalıdır.
