Turkey has applied for EU-membership, but still faces problems of lacking quality standards for bread wheat. Studies on the influence of S-fertilization on grain yield and bread-making quality of wheat (Triticum aestivum L.) in the region haven’t been carried out until today. This research was conducted for two growing seasons (2008-2009 and 2009-2010) at Adnan Menderes University Research and Experimental Farm located in the Western Turkey (Aegean region) at 37º 44’ N 27º 44’ E in order to determine the effects of nitrogen (0, 70, 140, 210 kg ha-1) supplemented with sulphur (0 or 40 kg ha-1) with respect to yield and bread-making quality of the varieties Golia and Sagittario, grown primarily in Western Turkey. S-fertilization had positive effects on grain yield and some quality parameters under Mediterranean conditions; however, signifi cant differencess were rather rare. Particularly the gluten-index and the sedimentation value promoted by S fertilization were among the tested parameters. Therefore, S-fertilization in improving bread-making quality of wheat in the region should not be disregarded. Grain yield and quality could be promoted simultaneously with increasing N-doses.
