Revitalization Of Plant Growth Promoting Rhizobacteria As An Effective Bioinoculant To Enhance The Growth, Production, And Stress Tolerance Of Vegetable Crops. A Short Review

Abstract

Now environmental pollution is a serious issue. The use of chemical fertilizers continuously can cause soil and water pollution. We know that the soil is a source of indigenous microorganisms. Among them, the plant-growth-promoting rhizobacteria (PGPR) are promising bioinoculants for vegetable crops that provide sustainable, environmentally friendly ways to increase growth, production, and stress tolerance due to the production of plant-growth-promoting properties (Phosphate solubilization, Indole acetic acid production, etc.). These advantageous bacteria penetrate the rhizosphere, form symbiotic associations, and support nutrient uptake, root growth, and general plant health. By enhancing water and nutrient uptake, controlling osmotic balance, and inducing the plant's immunological response, they also boost vegetable crop stress tolerance. The use of PGPR-based bioinoculants reduces the need for chemical pesticides and fertilizers while minimizing environmental contamination.
