Effect of Igran on the Rhizosphere Mycoflora of Vicia faba Plants Grown in Soils Infested with Orabanche crenata and Amended with Rhizobium leguminosarum

Ahmed M. Shalaby, Mohammed A. Rizk and Tarek A. A. Moussa

Either the recommended or double recommended igran dose significantly reduced the rhizosphere fungal, actinomycetal and bacterial count. The faba plants were unable to tolerate the 4-fold igran dose, thus enriching the rhizosphere with organic matter that helped flourishing the microorganisms in this area. The drop in soil invertase or amylase activity in igran-treated samples was far greater in the rhizosphere than the surrounding soil of the faba beans, whereas the differences in the cellulolytic activity was almost negligible. The biomass gain by the test fungi was hardly, if at all, affected by the presence of recommended igran dose a response that continued with larger dose application except Aspergillus ochraceus where it significantly stimulated the dry weight gain.
