Synergistic and Competence of Native Plant Growth Promoting Rhizobacteria on Direct Mechanism on Growth Plants: A Review

The most significant challenges facing farmers and plant producers worldwide are minimizing or neutralizing the impacts of environmental pressures on agricultural plants, safeguarding against pests and diseases, and simultaneously maintaining optimal plant growth and development. The environment and raising food quality standards require minimizing using of chemicals fertilizer. Plant growth-promoting rhizobacteria (PGPR) have the ability to promote plant growth through a range of mechanisms, both direct and indirect. These mechanisms include mineral solubilization, phytohormone and siderophore synthesis, and the utilization of extra secondary metabolites and enzymes. PGPR have a prospect in biofetilizer can improve the effectiveness of fertilization.
