Micro-organisms are the key components of the soil biodiversity. Both free-living and non free living soil biota beneficial to plant growth, usually referred to as plant growth-promoting rhizobacteria’s (PGPRs), are capable of promoting plant growth by colonizing the plant ischolar_main. These are associated with the rhizosphere, which is an important soil ecological environment and plant health for plant–microbes interactions. Beneficial micro-organisms that help in promoting plant growth, protecting from biotic and abiotic stresses, and significantly increasing soil fertility. Due to increase inputs of pesticides and fertilizers, the role of these micro-organisms is marginalized in sustainable agriculture. For increasing crop yields, the use of PGPRs has been well proven for its eco-friendly sound by promoting plant growth either direct or indirect mechanism. The mechanisms of PGPRs include resistance against plant pathogens, solubilizing nutrients for easy uptake, and maintaining the plant growth regulator hormone. PGPR may protect plants against pathogens by direct antagonistic interactions between the biocontrol agent and the pathogen, as well as by induction of host resistance. PGPR have the potential contribute to sustainable plant growth promotion.

Abstract


Micro-organisms are the key components of the soil biodiversity. Both free-living and non free living soil biota beneficial to plant growth, usually referred to as plant growth-promoting rhizobacteria’s (PGPRs), are capable of promoting plant growth by colonizing the plant ischolar_main. These are associated with the rhizosphere, which is an important soil ecological environment and plant health for plant–microbes interactions. Beneficial micro-organisms that help in promoting plant growth, protecting from biotic and abiotic stresses, and significantly increasing soil fertility. Due to increase inputs of pesticides and fertilizers, the role of these micro-organisms is marginalized in sustainable agriculture. For increasing crop yields, the use of PGPRs has been well proven for its eco-friendly sound by promoting plant growth either direct or indirect mechanism. The mechanisms of PGPRs include resistance against plant pathogens, solubilizing nutrients for easy uptake, and maintaining the plant growth regulator hormone. PGPR may protect plants against pathogens by direct antagonistic interactions between the biocontrol agent and the pathogen, as well as by induction of host resistance. PGPR have the potential contribute to sustainable plant growth promotion.
