The experiment was arranged based on a factorial arrangements in randomized complete block design with 13 treatments and three replications. The factors were involved priming with micronutrients (Zinc sulfat 4 mM), (Manganes sulfat 4 mM) and (Boric acid 8 mM) and the time of priming (12, 24, 36 and 48 h) along with control without priming. The results showed seed priming with micronutrients had significant effect on all traits. The highest of seedling stablishment percentage and seedling emergences rate in the farm and too the highest amount of oil percent, harvest index, the lowest period of planting until flowering showed in seed priming with manganese sulfate for 12 h. The highest of leaf area index, dry weight in flowering stage, weight of thousand seeds, No. boll per plant, and seeds yield showed in seed priming with manganese sulfate for 24 h. The highest No. seeds in boll, biological yield and seed concentration protein showed in seed priming with zinc sulfate for 24 h. The highest amount of Alpha Amilas activity showed in seed priming with manganese sulfate for 12 h. The highest concentration of zinc, managanes and boron in seed obtained in priming with zinc sulfat for 36 hours, manganes sulfat for 24 hours and boric acid for 24 hours respectively. In addition with respect to result, its seems seed priming with micronutrients especially zinc and manganese in 12 and 24 hours is a suitable method to increase the yield and yield components and also quality traits of safflower seed is Faraman cultivar.
