Abstract: Sustainable vegetable production in Africa requires innovative and low-cost soil fertility management strategies. Microbial consortia-based biofertilization integrates beneficial microorganisms that improve soil microbial health, nutrient mobilization, and crop productivity. This study evaluated the effects of bacterial and fungal consortia on soil enzyme activity, nutrient availability, and yield of brinjal (Solanum melongena L.) grown under tropical field conditions in Ghana. Treatments comprised Azotobacter chroococcum, Bacillus subtilis, Pseudomonas fluorescens, Trichoderma harzianum, and Glomus mosseae, applied individually and in combination. Results revealed that the microbial consortium significantly enhanced soil dehydrogenase, phosphatase, and urease activities by 48%, 39%, and 33%, respectively, compared with the control. Nutrient uptake and fruit yield increased by 27% and 25.4% respectively. The findings confirm that multi-strain biofertilization can sustainably enhance brinjal productivity and soil health in tropical African agroecosystems.
