Abstract: | The field experiment was carried out in one of the agricultural fields of Al-Khalis District / Diyala Governorate,Iraq, which is located 14 km north of Baquba District, during the autumn season of 2022, in soil with clay loam textured to study the effect of organic fertilization with humic and fulvic acid and the interaction between them on the growth and yield of thesunflower plants( Helianthus annuus L.). A two-factor experiment was carried out using three replications of the (RCBD) randomized complete block design. The first factor was sprayed with humic acid at a concentration of 6gm.L.-1And the second agent wassprayed with fulvic acid at a concentration of 6 gm.L-1The results showed that there was a significant superiority when adding humic acid + fulvic acid at a concentration of 6gm.L.-1In the average characteristic of plant height, stem diameter, chlorophyll index, plant leaf area, number of leaves per plant,the weight of 1000 seeds, total yield, percentage of oil in seeds, and percentage of protein in seeds.Keywords: humic acid, fulvic acid, organic acids, foliar nutrition, sunflower. |
