Abstract
Nutrient management is one of the critical inputs in achieving high Productivity of safflower. In order to determine yield components, seed and oil yields of safflower, an experiment was conducted as a factorial arrangement based on complete randomized blocks design with three replications at experimental agriculture farm in Jey and Ghohab, Isfahan, during summer 2011. The experiment was arranged with three nitrogen fertilizer levels (0,150 and 200 kgha -1 ) from urea source, two phosphorus fertilizer levels (0 and 50kgha -1 ) from triple super phosphorus and two levels of potassium fertilizer (0 and 50 kgha -1 ) from potassium sulfate. Nitrogen had significant influence on yield components. The number of seeds per capitula was significantly affected by phosphorus. Potassium had significant influence on fertile capitula per plant and 100 seed weight. Nitrogen, phosphorus and potassium had positively affected the seed and oil yields of safflower. The maximum number of yield components, seed and oil yields of safflower were obtained from the 150kgha -1 nitrogen, 50kgha -1 phosphorus and 50 kgha -1 potassium. It seems that 150kgNha -1 , 50kgpha -1 and 50kgkha -1 is suitable for this study.
