Summary The factors that influence inocula establishmentviz. soil fertility, organic manuring and interactions between Azotobacter and phosphobacteria were examined in unsterilised and sterilised soil with and without farm yard manure in green house conditions. During the experiments, the number of nitrogen-fixing and phosphate-solubilising bacteria were enumerated. At the end of experiment, dry weight of grain and its nitrogen and phosphate uptake were determined. Increased number of both types of bacteria in rhizosphere soil and greater yield and nutrients uptake were observed, when seeds were bacterised with single or mixed cultures as compared to uninoculated treatment. The number of organisms remained quite high in mixed cultures and was so for longer periods of plant growth. Addition of 2% farmyard manure further enhanced the bacterial population and crop productivity. This effect was more pronounced in sterilised soil.
