Bioformulation of Novel Liquid Biofertilizer using PGPR Strains Intended to Commercialization
Abstract
Plant growth promoting rhizobacteria (PGPR) are promising plant growth enhancer which increases agricultural produce through various mechanisms. Different PGPR based soil amendments are available in solid and/or liquid form for commercial purposes with particular emphasis on agricultural need. Recently, it is evident that liquid biofertilizers possess tremendous enhancing impact on agricultural produce when compared to solid biofertilizers. In the present research work, efficient PGPR strains (Pseudomonas, Azospirilium, Azatobacter and Bacillus) were used as consortium in new liquid based formulation with increased feasibility to the shelf life of the product. The application of present novel bioformulation employed at seed treatment, basal application and foliar spray on Tomato (Solanumlycopersicum), Cauliflower (Brassica oleracea.var. botrytis), Chili (Capsicum annum), Brinjal (solanummelongena) and Bitter gourd (Momordicacharantia ), results into significant increase in vegetative growth and production.The present research findings suggest that the significant yield percentage was noticed in cauliflower (23.9%), bitter gourd (21.5%), Brinjal (12.5%), Chili (10%), and Tomato (8.1%) as compared with chemical fertilizers. Taken together, it can be concluded that the present novel liquid-based-consortium bioformulation would not only be cost-effective, eco-friendly but a new intervention for agriculture and its dependents also.
