Abstract
The increasing demand for qualitative and varietal foods by the consumer society is a big concern for energy production, and utilization of that energy in a judicious manner for sustainable management of resources is a big challenge in the eminent future. Existing resources (land, water, fertilizer, etc.) and their socioeconomic aspects warrant the farming community to adopt alternative strategies aimed at enhancing the use efficiency of inputs and improve the environmental quality. The adaptability of microbes to thrive in different environments has prompted scientists to introduce microbial intervention in the agricultural processes. Bio-priming has the potential to fulfill many objectives of the modern production system with the use of beneficial microorganisms in an eco-friendly manner. Interestingly, it also plays a crucial role in enhancing the nutrient use efficiency of crops. There is rising evidence of a paradigm shift from the use of a single microbe to a consortium approach for efficient rhizosphere engineering in the context of sustainable agriculture. Our understanding of different signaling cascades, rhizosphere chemistry, and other mechanisms of plant-microbial interactions will frame suitable strategies to harness the best ecosystem services including improved resource use efficiency.
