The experiment was conducted at the agricultural research station of the College of Agriculture- University of Basrah in 2018-2019 season in sandy loam soils in order to study the effect of three concentrations of humic acid (0, 2 and 4 g.L-1) on the growth and yields of two hybrids of Broad bean ("Rico and Rama F1"). Split Plot Design by Randomized Complete Block Design (R.C.B.D) with three replications, and the least significant difference test (L.S.D) was used to compare averages at a probability level of 0.05. The most important results obtained are: The hybrid "Rico" is gave a significant increase in the number of branches.Plant-1, the percentage of flowering in addition to the average weight of the pod, while the hybrid "Rama F1" gave a significant increase in the number of flowers and pods.Plant-1, weigh of pod.Plant-1 (259.3 gm) in addition to the total yield (24.34 tons.ha-1). Humic acid concentrations 2 and 4 g.L-1 gave a significant increase in number of leaves.plant-1, leaf area, soft weight of vegetative, number of flowers.plant-1, number of pods.plant-1, average weight of pod, yield. Plant-1 (259.9 g) in addition the total yield (24.40 tons.ha-1), while control treatment gave a significant increase in the percentage of ripening flowers. The interaction between humic acid and hybrids had significant increase in all characters in the study except the percentage of ripening flowers.
