Abstract
A field experiment was carried out in the Al-Jazeera region of Ramadi city, Anbar Governorate, at autumn season of 2020 in sandy soil to study the effect of stimulating sunflower seeds with four levels of salicylic acid (0, 125, 250 and 375 mL−1) and spraying with humic acid( 0, 250 and 500 mL−1) Where the results showed that the concentration of 375 mL−1 of salicylic acid recorded the highest average of the characteristics, the number of seeds per disc and the weight of 1000 grains, and the seed yield was (2034.9 seeds, 80.81 g and 164.97 g. plant−1) respectively. While the second treatment of spraying with humic acid recorded the highest mean for the characteristics, the number of seeds per disc and the weight of 1000 g, and the seed yield was the highest average (1752.3 seed. disc, 68.43 g and 124.16 g. plant−1).
