An experiment was conducted during winter season of 2009-2010 at Al- Dair, Basrah Governorate with objective of exploring the effect of treatment with salicylic and ascorbic acids and method of application on growth, flowering and yield of green broad bean plants (Vicia faba L.) cv." Luz de otono". The study included 15 treatments which were the combinations of two factors. The first factor was five levels of salicylic acid and ascorbic acid [o , salicylic acid (15 ,30 mg.l.-1) and ascorbic acid (50,100 mg.l.-1].The second factor was methods of treatments: 1. seed soaking , 2. seed soaking + plant spraying and 3. plant spraying only. A split plot design was used with three replicates. Results showed that treatments with both salicylic acid and ascorbic acid caused reduced significantly the number of days to opening of the first of florat and significantly increased the number of inflorescences, florat per plant , yield and its components as compared with the control. Salicylic acid at 15 mg.l.-1gave the highest values with respect to pod length , number, as well as the weight of 100 seeds and green pod yield per plant , green pod productivity, weight of fresh seeds per plant. Plants treated with salicylic acid at 30 mg.l.-1gave the highest number of seeds/pod , and pod weight, seeds protein and total soluble solids. Treatment of (seed soaking + plant spraying) with Salicylic acid at 15 mg.l.-1 gave the highest values of pod yield per plant (474.16 g.)and the green pod productivity (9.272 tone.donum-1)and the highest yield of fresh seeds per plant (160.55 g.), and productivity of green pods (3.319 Tone . donum-1).
