Abstract
Effect of organic amendments on the microbial population of rhizosphere and non-rhizosphere soils was studied taking a number of dry and green plant materials. All the amendments had marked stimulatory/inhibitory effects on the population of fungi and bacteria in the rhizosphere but the magnitude varied with the amendment as well as variety and age of the plant. They also affected the relative population of different fungi in the rhizosphere. A number of them suppressed the population of Fusaria and stimulated that of Aspergilli.
