Brinjal (Solanum melongena L.) is an important vegetable crop with high nutritional and medicinal value. Enhancing its growth and quality through eco-friendly approaches like microbial biofertilization can help improve both productivity and fruit composition. In this study, plant growth-promoting microorganisms were used to observe their influence on plant growth, nutrient content, and the enrichment of bioactive compounds in brinjal. A consortium of Azotobacter chroococcum, Bacillus subtilis, Pseudomonas fluorescens, Trichoderma harzianum, and Glomus mosseae was applied to plants under field conditions. The inoculated plants showed better vegetative growth, higher yield, and improved biochemical parameters such as total phenolics, flavonoids, and antioxidant activity. Notably, the levels of chlorogenic acid and nasunin were also higher in fruits obtained from microbial treatments. These results suggest that the combined microbial inoculation could be a sustainable method for improving the pharmacological potential of brinjal.
