Determining Forage Quality Values in Sole and Mixtures Sowings of Some Warm Season Perennial Grasses Species with Alfalfa in the Irrigated Conditions of ？anl？urfa

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 ？anl？urfa during 2016 and 2017. The subjects of the study consisted of 10 treatments. There were 6 mixtures 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 averages, the investigated traits had ranges as following; dry matter yield 335.57-729.79 kg/da, crude protein content 8.73%-21.50%, crude protein yield 33.91-176.21 kg/da, 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, crude protein content, crude 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. Hence, alfalfa is recommended for dry forage production in ？anl？urfa 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 mixtures treatments
