Inoculation of bioinoculants in crop cultivation is performing vital role in sustainable agriculture. It is well known that the carrier-based bioinoculants are being very effective as carrier determines the shelf-life of the inoculant. Hence, the selection of superior carrier is very crucial for maintaining shelf-life of the inoculant for the periods of storage and for better performance in the field use. In the present study, the population of Streptomyces violaceusniger was assessed at ten days interval in different carrier materials. The population of S. violaceusniger and Streptomyces exfoliates were observed at the end of 30 d. In addition, the talc based formulation was found to be highly suitable carrier to deliver both S. violaceusniger and S. exfoliatus. The results clearly revealed that the cell densities of S. violaceusniger and S. exfoliatus were high in the nutrient medium supplemented with glycerol when compared to nutrient broth alone.

Abstract


Inoculation of bioinoculants in crop cultivation is performing vital role in sustainable agriculture. It is well known that the carrier-based bioinoculants are being very effective as carrier determines the shelf-life of the inoculant. Hence, the selection of superior carrier is very crucial for maintaining shelf-life of the inoculant for the periods of storage and for better performance in the field use. In the present study, the population of Streptomyces violaceusniger was assessed at ten days interval in different carrier materials. The population of S. violaceusniger and Streptomyces exfoliates were observed at the end of 30 d. In addition, the talc based formulation was found to be highly suitable carrier to deliver both S. violaceusniger and S. exfoliatus. The results clearly revealed that the cell densities of S. violaceusniger and S. exfoliatus were high in the nutrient medium supplemented with glycerol when compared to nutrient broth alone.
