A field survey was carried out to isolate effective strains of Rhizobium from the Indian Thar Desert and applied them to mungbean to assess their impact on enhancing production and improving soil fertility. Based on morphological, biochemical, and physiological characterization, 10 out of 26 isolates were identified as Rhizobium and exhibited positive results for nitrogen fixation, siderophore production, phosphate solubilization, and antagonistic activity against Aspergillus niger green mold. A Rhizobial consortium was formed using these potential PGPR strains and applied as a co-inoculant to mungbean to assess its impact on plant growth under field conditions. The Rhizobial consortium + 50% NPK was found significant than the Rhizobial consortium alone. Whereas Rhizobial consortium treatment without NPK was also impactful in comparison with uninoculated control. This study aimed to evaluate the potential of Rhizobial consortia of Indian Thar and their efficacy in Gangetic plains.
