Abstract
Damping off and root rot are a worldwide diseases, caused destructive yield losses of legumes field crop of Vicia fabae, Cicer arietinum and Lupines terms. The biological control of damping off and root rot diseases using microorganisms antagonistic to growth and development of the fungi were investigated under greenhouse conditions at the Experimental Farm, Faculty of Agriculture, Suez Canal University, Ismailia, Egypt. The results exhibited that Rhizobium spp. and Trichoderma sp. fungi scoffed at the potential or ability to their compatibility and in combined effects in controlling the fungi, which caused the damping off and root rot. This resulted in an improvement in many plant growth parameters, which are ultimately expressed in increasing the yield components of branches plant-1, pods plant-1, seeds pod-1, mean seed weight and then increase seed yield of the legume field crops broad bean, chickpea and lupine plants. The results suggested that the Rhizobium spp. and Trichoderma sp. can be used as biological control of some soil-borne fungal diseases causing significant yield losses in legumes field crops.
