Plant Growth Promoting Rhizobacteria (PGPR): Microbes in sustainable agriculture

Abstract

Plant growth promoting rhizobacteria (PGPR) contain diverse type of plant growth promoting attributes that has many beneficial effects on crop productivity. The PGPR appear to promote the plant growth via - suppression of plant disease (bio-controls), enhanced nutrient achievement, or phytohormone production (bio-fertilizers). The PGPR protect plants from several biotic and abiotic stresses. Co-inoculation of PGPR can ease the adverse effects on crop plants due to various environmental stresses such as soil salinity, droughts, temperature and nutrient deficiency. During the last couple of decades given the negative environmental impact of artificial fertilizers and their increasing costs, the use of PGPR for sustainable environment and safe agriculture has increased globally. Thus, the PGPR offer an environmentally sustainable approach to increase crop production for future generation.
