Abstract: Vermicompost is a mesophilic biodegradation product where biofertilizer are commonly known as microbial inoculants that enhance plant growth. Pseudomonas fluorescens and Azotobacter sp. was characterized as a negative rod shaped bacteria showing positive biochemical test, Pseudomonas fluorescens and Azotobacter sp. was assayed for phosphate, zinc, potassium solubilization in different media. It produces IAA, Auxin, HCN and it showed PQQ independent activity. Phosphate solubilization index was higher in NBRIP (2.44±0.09) as compared to PVK medium (2.22±1.11). Pseudomonas fluorescens and Azotobacter sp. had a shelf life of 70 days. After harvesting the crop Physico-chemical analysis of soil shows that vermicompost and vermiwash had increases the N%, P%, K%, OC% and pH changed from 7.5 to 6.9. Vermicompost and Biofertilizer were amendments the soil. pH fluctuated among all treatments, T6 (vermicompost + vermiwash + carrier based biofertilizer (Pseudomonas fluorescens and Azotobacter sp.) showed best growth of Solanum melongena for all growth parameters viz shoot length (138.2±2.03), root length (29.26±1.29), no. of branches (7.27±0.23), no. of leaves (71.33±0.30), leaf length (13.707±1.19), no. of flowers (13.6±0.2), no. of fruits (13±0.41), fruit diameter (16.59±1.55), fruit length (10.4±0.66). In conclusion, use of vermicompost, Vermiwash, Pseudomonas fluorescens and Azotobacter sp.as biofertilizer enhanced growth and yield of Solanum melongena.
