Bu araştırma; Şanlıurfa sulu koşullarında bazı çok yıllık buğdaygil sıcak mevsim bitkisi türleri ile yoncanın saf ve karışım halinde ekimlerinde elde edilecek kuru madde verimi ile ot kalite özelliklerinin belirlenmesi amacıyla 2016 ve 2017 yıllarında yürütülmüştür. Araştırmada toplam 10 uygulama denenmiş olup, bunlar yonca (Medicago sativa), Rodos otu (Chloris gayana L.), köpekdişi ayrığı (Cynodon dactylon L.) ve adi yalancı darı (Paspalum dilatatum Poir.) türlerinin saf uygulamaları ile bu türlerin değişik kombinasyonlarından oluşan 6 karışım uygulamasından oluşmaktadır. İki yıllık ortalamalara göre, araştırmada incelenen özellikler aşağıdaki aralıklarda değişim göstermiştir; kuru madde verimi 335.57-729.79 kg/da, ham protein oranı %8.73-%21.50, ham protein verimi 33.91-176.21 kg/da, ADF oranı %27.86-46.16, NDF oranı %40.19-%79.44 ve sindirilebilir kuru madde oranı (SKMO) %52.94-%67.20. Araştırma sonucuna göre; en yüksek kuru madde verimi, ham protein oranı, ham protein verimi, sindirilebilir kuru madde oranı ile beraber, en düşük ADF ve NDF oranına sahip saf yonca (1) uygulaması hem ot verimi hem de ot kalitesi bakımından en iyi uygulama olarak belirlenmiştir. Ancak yonca otunun yaş ot olarak hayvanlarda şişmeye neden olması nedeniyle, otlatma amaçlı mera tesislerinde, diğer karışımlardan daha yüksek kuru madde verimi ve ot kalitesine sahip olması nedeniyle, yonca (%30) + Rodos otu (%70) (5) ikili karışımı önerilmektedir.
The study was conducted to determine dry matter yield and forage quality traits of some warm season perennial grasses species mixtures with alfalfa and their sole treatment in the irrigated conditions of Sanlıurfa during 2016 and 2017. The subjects of the study consisted of 10 treatments. There were 6 mixture treatments between alfalfa and the warm season perennial grasses species. Also, there were sole treatment of alfalfa (Medicago sativa), rhodes grass (Chloris gayana L.) bermuda grass (Cynodon dactylon L.) and dallis grass (Paspalum diladatum Poir.). According to the two-years average, the investigated traits had ranges as following; dry matter yield 335.57-729.79 kg/day, raw protein content 8.73%-21.50%, raw protein yield 33.91-176.21 kg/day, ADF content 27.86-46. 16%, NDF content 40.19%-79.44%, dry digestible matter ratio 52.94%-67.20%. Results of the study revealed that the highest dry matter yield, raw protein content, raw protein yield and dry digestible matter ratio and the lowest ADF and NDF contents were in the sole alfalfa treatment. The results showed that sole alfalfa (1) treatment had the best forage yield and forage quality. Thus, alfalfa is recommended for dry forage production in Sanlıurfa conditions. On the other hand, due to bloating problem of fresh forage of alfalfa, when grazing aimed, alfalfa (30%) + Rhodes (70%) (5) binary mixture is recommended, because its dry matter yield and forage quality criteria were found superior to other mixture treatments.
