Biofertilisers function as key player in sustainable agriculture by improving soil fertility, plant tolerance and crop productivity:

Current soil management strategies are mainly dependent on inorganic or synthetic fertilisers which cause a serious threat to the environment. The exploitation of beneficial microbes as a biofertiliser has become paramount importance in agriculture sector for their potential role in food safety and sustainable crop production. The eco-friendly approaches inspire a wide range of application of plant growth promoting rhizobacteria (PGPRs), mycorrhizal fungi, nitrogen fixing bacteria, solubilising bacteria for phosphate & potassium and many other useful microbial products which led to improved nutrient uptake, plant growth and tolerance. Bio-fertilizers improve functional traits such as plant growth productivity, nutrient balance, plant defense and protection. Bio-fertilisers trigger various growth and defense-related genes which signal a network of cellular pathways resulting in plant defence response and crop improvement.
