Abstract :
To evaluate the priming effect of potassium resources and foliar spray of micronutrient on the yield and yield components of sunflower ( Farrokh cultivar ) a two factorial experiment was carried out at Agricultural and Natural Resources Station of Khoy ( W. Azarbaijan-Iran ) in the crop year of 2014. The experiment was conducted on a randomized complete block design with 12 treatment and 3 replications. The priming factor was accompanied with the three levels of potassium chloride, potassium nitrate, and potassium sulfate; spraying factor accompanied with four levels of non-spraying and spraying with zinc, boron, and a combination spraying of zinc and boron. The variance analysis revealed a significant effect of priming of the seed on the diameter, number of seeds per head, and seed yield, but it had no significant impact on the other traits. The maximum number of seeds per head was 656.7 for zinc spraying and 669.7 for boron spraying. The minimum number was 511.8 for non-spraying. Combined spraying of boron and zinc showed maximum yield of 3899.9 kg per hectare and non-spraying showed the minimum yield of 2928.8 kg per hectare. The bilateral effect of these two factors affected the traits, seed yield, shoot-ash percentage, and harvest index. However, the highest seed yield was observed as 4040 kg/h for priming with potassium chloride and spraying with boron and the least seed yield was observed as 2652 kg /h for priming with potassium sulfate to increase the head diameter was more effective than other sources of potassium. Simultaneous spraying of zinc and boron increased the diameter, number of seeds per head, seed yield, and harvest index, while non-spraying reduced the number of seeds per head, seed yield, and biological yield. The correlation of bush diameter with seeds number, seeds yield and biological yield were significant, and so were the seed number correlation with seed yield, biological yield and its hollowness percentage.
