The aim of this investigation was to determine the effect of different nitrogen doses on yield and some quality properties of sorghum x Sudan grass hybrids (Sorghum bicolor (L.) Moench x Sorgum sudanense (Piper) Stapf) cultivars (Greengo and Sugar Graze II) in Musulca village-Edirne ecological conditions in 2014. The experiment was laid out in a two-factor factorial in randomized complete block design with four replicates. The different nitrogen doses (0, 4, 8, 12, 16 kg da-1) and cultivars (Greengo and Sugar Graze II) affected the leaves/plant, leaf/stem ratio, total green fodder yield, total hay yield and neutral detergent fiber ratio. Contrary to crude fiber ratio, acid detergent fiber and neutral detergent fiber; the stem diameter, the leaves/plant, leaf/stem ratio, total green fodder yield, total hay yield, crude protein ratio and total protein yield increased depending on the nitrogen doses. In cv. Greengo, total green fodder, hay and protein yields were 1585.60 kg da-1, 528.70 kg da-1 and 58.16 kg da-1, respectively, by not applying nitrogen. The nitrogen application at the rate of 16 kg da-1 significantly decreased crude fiber (28.03-29.20 %) and neutral detergent fiber (57.27 %) over control. According to results, cultivation of the cv. Sugar Graze II for higher forage yield and quality at the 16 kg da-1 application is recommended in Edirne province and similar ecological conditions.
