Implementation of Biofortification Technology by Using PGPR for Sustainable Agricultural Production

A major challenge in the twenty-first century is to fulfill the hunger need of day-by-day increasing populations. Hence, there is the need to increase the productivity of cultivated land and food fortification. The use of biofortification nutrient and mineral content can be increased in staple food. Economically important crops have limited production yield due to the scarcity and hyper-accumulation of the nutrients and attack of plant pathogen. There are several microbes such as fungi, actinomycetes, cyanobacteria, and plant growth-promoting rhizobacteria (PGPR) possessing plant growth-promoting mechanisms. These microbes help to increase nutrient uptake (e.g., Mn, P, Fe, S, Zn, etc.) by making it phyto-available in rhizosphere. Plant-microbial interaction (mycorrhization and actinomycetes interaction) improves the health of plant by protecting them from attack of phytopathogen and toxicity of hyper-accumulation of nutrient.
