Abstract
Plastic pots sown with seeds of faba bean variety Giza 429 susceptible to chocolate spot disease caused by Botrytis fabae were grown in a screenhouse . Two biofungucides (Bioarc and Biozeid), one green Algae (Ulva) and two chemical fertilizers (Alpha and Oris) were utilized in this research. Data obtained showed that disease severity was higher in the season of 2008/2009 than the season of 2009 / 2010. Bioarc and Biozeid significantly controlled the disease more than the other tested products.Bioarc and Ulva gave the highest increase in fresh weight, while Bioarc and Biozeid were superior in increasing the dry weight. Ulva and Alpha showed the higher plant height and also the number of branches of shoots. In addition, Alpha and Biozeid gave the highest weight of 100 seeds while Ulva and Alpha significantly increased the number of pods / plant. Also , Ulva was the only product increased seed number / pod. Determination of NPK level in faba bean shoot revealed that tested materials increased the level of the three elements to different degrees. Bioarc and Alpha significantly increased the highest level of P while the effect of the other materials was variable. Similar trends were observed in the two seasons of trials.
