Abstract: Two field experiments were conducted at the experimental farm of Tag El-Ezz Agric.Res. station ,Dakahlia during 2004 /2005 and 2005/2006 seasons to study the effect of three antioxidant substances (hydroquinone, citic acid and benzoic acid at concentrations of 5,10 and 15 mM on growth , yield and yield components of three fib bean cultivars (sakha 1,Giza3 and Giza2)as well as the severity of chocolate spot disease caused by Botrytis faba . Generally ,the application of benzoic acid at any concentration showed priority and proved to be the best and most effective in reducing disease severity on all tested cultivars. Hydroquinone came in the second order as compared to control treatment. Citric acid showed the lowest effect in this respect.
The foliar application of antioxidants on faba bean cultivars significantly increased growth and yield components which could be summarized as follows: 1)Sakha 1 cultivar surpassed Giza 3and Giza2 onnumber of branches ,number of pods and seed weight /plant , 100-seed weight and seed yield, but Giza3 cultivar surpassed Sakha 1and Giza2 in plant height and straw yield in the two seasons .2)Citric acid gave the highly significant increase in number of pods &seed weight /plant and seed yield in both seasons ,3) Using 15mM of antioxidant substances give hogher significant increase in number of branches ,pods and seed weight /plant ,100-seed weight and seed yield compared with control and4) The interaction between faba bean cultivars and antioxidants had a significant effect on plant height in both seasons and on the 100-seed weight and seed yield in the first and second seasons ,Sakha1 with citric acid was more effective in this respect.
