Abstract: The aim of this study carried out in Van Turkey in 1997 and 1998 was to determine the effects of different forms and doses of nitrogenous fertilizers on the safflower (Chartamus tinctorius cv. Dinçer 5-118) yield and yield components. The nitrogenous fertilizers (Ammonium sulphate (21% N), urea (45% N) and ammonium nitrate (33% N) and their four different doses (0, 40, 80, 120 kg ha-1) were examined in a Randomized Block Design with three replication. The plant height, the plant head number, the 1000 seed weight, the seed yield, the crude oil content and the crude oil yield were investigated. The nitrogenous fertilizer forms had a significant effects (p<0.01) on the seed yield in both years, but not on the crude oil content and the crude oil yield. The different nitrogenous fertilizer doses had a significant effects (p<0.05) on both the seed and the crude oil yields in both years, but not on the crude oil content. While the highest seed yield and crude oil yield (1994 kg seed ha-1 and 497 kg oil ha-1) were obtained from the application of the 120 kg N ha-1 ammonium nitrate, the application of the 80 kg N ha-1 urea gave the highest seed yield (1750 kg seed ha-1 and the application of 80 kg N ha -1 ammonium nitrate gave the highest crude oil yield (477 kg oil ha-1) in 1998. While the highest average seed and the crude oil yields (1597 and 422 kg ha-1, respectively) were obtained from the ammonium nitrate application, the 120 kg N ha-1 application dose gave the highest average seed and the crude oil yields (1685 and 437 kg ha-1, respectively).
