Abstract Background Two field experiments were carried out in Researches and Production Station of National Research Centre, Al-Nubaria District, Al Behaira Governorate, Egypt. To study the effect of indole acetic acid (IAA) and /or gibberellic acid (GA3) on growth, photosynthetic pigments, yield, and chemical composition of mungbean seeds, different concentrations of IAA and/or GA3 were used. Results Results indicated that all treatments caused significant increases in morphological criteria, biochemical parameters, and yield of mungbean plants. IAA or GA3 with 50 mg/l concentration recorded the best values growth photosynthetic pigments, as well as, endogenous auxins, GA3, and cytokinins. Interaction of IAA 50 mg/l + GA3 50 mg/l gave the most effective treatment. The superiority of treatment IAA 50 mg/l, GA3 50 mg/l, and interaction of IAA 50 mg/l + GA3 50 mg/l recorded the same trend due to yield and yield components in characters’ plant height, pods no./plant, pods weight/plant, seeds no./pod, seed yield, straw yield, biological yield, total carbohydrates, protein in seeds (%), and N in seeds (%). Conclusion It could be concluded that foliar spray of 50 mg/l IAA + 50 mg/l GA3 was the most effective treatment on increasing growth and yield of mungbean.
