 ABSTRACT

A laboratory investigation was carried out to study the survival rate of an agriculturally important microbial consortium (Rhizobium sp., Bacillus megaterium and Pseudomonas fluorescens) in a selected formulations (alginate based, fluid bed dryer, lignite based and liquid) as a single, dual and triple inoculants. After 180 days of storage, the higher survival rate (per cent) of Rhizobium sp., (95.36 per cent), Bacillus megaterium (93.81 per cent) whereas, Pseudomonas fluorescens recorded of 95.46 per cent in alginate based formulations. Overall, the maximum viable cells were maintained in the alginate based formulations followed by liquid formulation and lower per cent survival rate of the inoculants were observed in fluid bed dryer based formulations.
