AbstractAn experiment was conducted through spring season (15/3) and autumn season (15/7) to investigate the response of two sun flower genotypes ( Zahrat al Iraq and Aqmar) to addition of Humic acid with 500 cm3/100 L water, the experiment under split block design in RCBD with three replications, the plant was harvesting at 20/5 and 15/10 to spring and autumn respectively, the result show: Significant differences between plant genotype in two lag , the Zahrat al Iraq genotype give higher value in plant height , disk diameter , foliar area , stem diameter , and number of leaves , while no difference at chlorofyle leaf content between genotype, the addition of humic acid at two sprays increase significantly ( 182.1,131.57 ) cm , (21.65 , 18.69)cm , ( 0.629 , 0.496 ) m2 , (2.33 , 2.00) cm , ( % 45.25, % 45.09) , (28.35, 28.76 ) all parameter above for both the seasons respectively.
