| Abstract | ||
| This study was conducted during 2011-2013 winter season in Abo- khassib, Basrah, to investigated the effect of foliar spray of chelated iron and number of spray on growth and yield of green broad bean ficia faba var. Luz de otono, Turkish origon. The design of experiment was established as complete randomized block design with eight factorial treatments, at four concentration (0, 50, 100 and 150)mg.l-1 of chelated iron 7% and number of spraying once and twice. Dunean’s multiple range test was used at probability of 0.05 and the results were summarized as follow: The spraying with chelated iron at height concentration led to significant increase in the total chlorophyll in leaves. The concentration at 100 mg.l-1 led to increasing the number of pods and yield pods and the yield of fresh seeds (ton.donam-1) with significant decreasing in total soluble solid. The result of experiment showed that the plants which were sprayed twice had significantly increased comparing with the plants which were sprayed once for the increasing of total chlorophyll in leave and the range of seeds number in pods but the plants which were sprayed once had significant effect in total soluble solid at fresh seeds. The interaction between the concentration of chelated iron and number of spraying showed significant effect in pods yield and total product of pods. The plants that sprayed at the concentration 100 mg.l-1 for one spraying gave highest yield and highest total production (626.9 g and 7.880 ton.donam-1) respectively. | ||
