| Abstract | ||
| An experiment was conducted during the winter season of 2011-2012 at Aba Al-Ghaseab- Basrah. The aim was to study the effect of foliar spraying of citric acid and the number of spraying on growth and green yield of broad bean cv. Luz de otons. The experiment included eight treatments came from the interaction among four citric acid concentration of (0, 75, 150, 225) mg L-1 applied with spraying (one, two) time. Randomized complete Block Design was used in a factorial experiment; Duncan’s Multiple Range Test was used at probability of 0.05. Results showed that foliar spraying of citric acid at 225 mg. L-1 caused a significant increase in plant height, branch number, leaf number, leaf area per plant, pods number, green pod yield per plant, green pod productivity, fresh seed yield per plant and productivity, pod length, weight of 100 seeds, percentage of dry matter on seeds and total soluble solids compared with control treatment. Spraying with two times caused a significant increase in plant height and percentage of dry matter on seeds. Compared to spraying with one’s time. The interaction of the two factors of study had a significant effect in some characteristics. The highest fresh seed yield per plant and productivity came from foliar spray with 225 mg.L-1. Citric acid every two time 2324 gm. plant-1 and 2.921 ton. Donum-1 respectively. | ||
