The aim of this study was to determine the effects of different nitrogen rates applied by dividing on the seed yield, yield components, oil content and oil yield of Dincer safflower cultivar. The study was conducted at randomized complete block design with three replication under Ankara conditions in 2011 and 2012. In the study, 13 different applications (T-1: 0 kg/da N, T-2: 5 kg N/da at sowing, T-3: 5 kg N/da in term of rosette, T-4: half of 5 kg N/da with sowing other half part at initiation of stem elongation stage, T-5: half of 5 kg N/da with sowing other half part in terms of rosette, T-6: 10 kg N/da at sowing, T-7: 10 kg N/da in term of rosette, T-8: half of 10 kg N/da with sowing other half part at initiation of stem elongation stage, T-9: half of 5 kg N/da with sowing other half part in terms of rosetta, T-10: 15 kg N/da at sowing, T-11: 15 kg N/da in term of rosette, T-12: half of 15 kg N/da with sowing other half part at initiation of stem elongation stage, T-13: half of 15 kg N/da with sowing other half part in terms of rosette) were treated. Results from a two-year study on nitrogen application for safflower under Ankara conditions indicated that the highest seed and oil yield were obtained by applying the rate of 15 kg N/da as 1/2 at sowing + 1/2 at initiation of stem elongation stage.
