Evaluation of the Co-inoculation Effect of Rhizobium and Plant Growth Promoting Non-rhizobial Endophytes on Vigna radiata.

A unique feature of leguminous plants is the establishment of symbiotic bacterial genera inside root or stem nodules that is being recently re-evaluated for investigating the micro-flora discrete to nitrogen fixation. The present research was carried out to evaluate non-rhizobial endophytes and Rhizobium from root nodules of Vigna radiata and ascertain their co-inoculation effect in pot and field conditions. Each strain displayed one or more plant growth-promoting behaviors in varying degrees.
