The present investigation was conducted to find out the effect of vermicompost and urban compost as amendment with talc in maintaining the shelf life of microbial inoculants such as Bradyrhizobium japonicum, Bacillus megaterium and Pseudomonas fluorescens as single, dual and triple inoculants. Talc amended with organic materials maintained better shelf life of microbial inoculants than talc. Maximum viable cells and per cent survival of microbial inoculants were recorded in triple inoculants in all the carrier based formulations followed by dual and single inoculant formulations.
