Potential of Rhizosphere Bacteria for Improving Rhizobium-Legume Symbiosis

摘要: About 60 % of the earth’s available nitrogen is fixed via biological fixation (BNF). Being a major contributor to BNF, Rhizobium-legume symbiosis can provide well over half source nitrogen. Actually, results in formation nodules on legume roots where rhizobia fix from atmosphere. But nodulation and complex process dependent compatibility potential both partners under variable soil environmental conditions. Although, some selected efficient effective traits legumes have shown encouraging results, there need consistent positive influence maximize growth yield Hence, use means capable improving function symbiotic essential. Co-inoculation Rhizobium species with favorably interacting plant growth-promoting rhizobacteria (PGPR) considered an applied, cost-effective, efficient, environment-friendly approach further improve productivity conditions because they broad spectrum mechanisms actions reliability inocula without genetic engineering. In addition, these PGPR when used combination also strategies for dealing stressful like salinity, pH, temperature, drought, heavy metal, pathogens which could impose limitations capacity symbiosis. This chapter highlights various compatible specific their phytostimulatory contributing augmentation rhizobial enhancement
