Abstract: A field experiment was conducted at the research field station of the Field Crops Department, College of Agricultural Engineering Sciences, University of Baghdad, Jadriya, during the year 2017-2018— the experiment aimed to study the effect of growth regulator gibberellin on broad bean growth and yield. In a factorial experiment according to RCBD design, the first factor was gibberellin spraying stages (the beginning of vegetative growth and the beginning of flowering), while the second factor was gibberellin concentrations (100, 200, and 300 mg L1), in addition to the comparison treatment, which was sprayed with water only. It was flowering by giving it the highest average plant height, number of pods, and seeds per pod. The results showed the superiority of the spraying stage at the beginning of flowering by giving it the highest mean of plant height, number of pods, and number of seeds per pod. In the spraying phase at the beginning of flowering (S2) and a concentration of 300 mg L-1, the highest average number of pods per plant reached 20.00 pods per plant. In comparison, a treatment at the beginning of flowering (S2) and a concentration of 200 mg L-1 achieved the highest average number of seeds per pod, reached 4.50 Seed in the pod, and achieved the spraying stage at the beginning of vegetative growth (S1) and the concentration was 200 mg L-1, the highest average was 133.3 g.
