Askona, Karola and Silvia) and spring rapeseed (cv. Lirawell, Semu 86/225 Na and Westar). The experiment was conducted in the research area of the Field Crops Department, Faculty of Agriculture, Dicle University in the 1995-1996 and 1996-1997 winter growing season in Diyarbakir. Fatty acid composition was not affected by N doses, but it varied among cultivars. The composition of the fatty acid of the rapeseed cultivars was 4.07-4.21% palmitic acid, 0.288-0.320% palmitoleic acid, 2.12-2.28% stearic acid, 65.60-66.58% oleic acid, 16.44-18.62% linoleic acid, 6.40-7.01% linolenic acid and 1.27-2.01% eicosenic acid.]]>Anonymous,1995Arioglu, H.,1997pp: 1-98pp: 1-98Kayahan, M.,1991pp: 1230pp: 1230Kirici, S. and M.
