It is well established that synthetic chemical fertilizers like Urea and DAP etc. are unsustainable for producing cereals like wheat in Indian agricultural economy and ecology. Microbial bio fertilizers e.g., Azotobacter chroococcum and Bacillus subtilis etc. are usually considered as suitable free living eco-friendly nutrient provider to cereals including wheat (Triticum aestivum L.,) however, the efficacy of these bio fertilizers is low and needs to be increased significantly to replace chemical fertilizers from the main stream Indian agriculture. We have demonstrated that optimising the doses of A. chroococcum and B. subtilis, and entrapping them in organic matrix based super granules, the availability of nutrients in soil and plants and soil fertility can be significantly improved. Subsequently, it results to higher plant growth, crop productivity and grain yield of wheat in experimental fields and reduces the emissions of NOx. Our results indicate that increase in efficiency of existing bio fertilizers can also be achieved by optimising its dose for different agro-climatic conditions and by selecting a suitable carrier for its storage and application.
