A formulation was developed using fluid bed dryer in a suitable carrier with agriculturally beneficial microorganisms; Acinetobacter sp., Azotobacter chroococcum and Bacillus subtilis in single, dual and triple combinations by using talc and skim milk powder as carrier material. Survival of these inoculant microorganisms was determined at different intervals till 365 days of storage. There was a maximum survival in triple inoculants with no contamination during the storage period when compared to lignite formulation. Green house experiment was conducted to study the effect of this inoculant formulation on Finger millet (Eleusine coracana Gaertn.). The results indicated that plant growth parameters, nitrogen and phosphorus uptake were maximum in plants inoculated with triple inoculants followed by dual and single inoculants as compared to uninoculated control. Results were more pronounced in plants receiving nutrients (NPK).
