The minerals, vitamins, fiber and oil included in maize make it a particularly good source of these nutrients. Plant growth-promoting bacteria have been demonstrated to be useful agents for protecting host plants from pathogens and stress conditions in addition to enhancing plant growth and development. In the current study, bacteria from the rhizosphere of winter maize was isolated and their antagonistic activity against Rhizoctonia solani and plant growth-promoting qualities was assessed. Four soil samples yielded a total of thirteen microorganisms, of which eleven showed antagonistic activity towards the disease Rhizoctonia solani. Of these eleven isolates, seven could create ammonia, nine could break down inorganic phosphate in a test tube, and eight could dissolve zinc.
