Description Soil is an integral part of the complicated natural environment which is
very much alive with complex ecosystem of microbes. Among them, the symbiotic
association of rhizobacteria with plants especially on agriculturally important crops
is very much advantageous in improving the soil and plant health. These plant
growth-promoting rhizobacteria (PGPR) have evolved over the years and involved
in many plant functions such as growth promotion, root development, colonization,
production of metabolites and in eliciting plant defence mechanism against abiotic
and biotic agents. The PGPR’s ability to fix the atmospheric nitrogen, solubilize
phosphate, potassium and zinc, produce siderophore along with wide variety of
phytohormones and secondary metabolites such as antibiotics have attributed to their
significance as biocontrol agents. These functions lead to their application as
biofertilizers, biopesticides, bioprotectants and phytostimulators. The employment
of these PGPR is very much important in agricultural fields as they reduce the burden
of chemical fertilizers and pesticides to the farmers and in turn promises an increased
crop yield. This chapter discusses the symbiotic association of PGPR with plants in
detail including their direct and indirect mechanisms and basis of their induced
systemic defence mechanism. It also highlights the use of bioinoculants and nanoformulations
of PGPR as an effective tool towards enhanced agricultural production
and to combat the plant diseases in an eco-friendly manner.
