treatment T2 (100% RDF + FYM @ 10 t ha -1 + Azospirillum @ 5 kg ha -1 + PSB @ 5 kg ha -1 ) at<br />

blooming and harvest stage, respectively and it was on par with 125% RDF (available P - 67.00,<br />

65.67 kg ha -1 and available K -432 and 412 kg ha -1 ) depicted in table 1. It enhances the P<br />

concentration in solution through the mineralization <strong>of</strong> organic P and solubilization <strong>of</strong> native soil<br />

P compounds by producing organic acids (Roy et al., 2017). Significantly higher protein content<br />

(12.29%) was recorded in the treatment T2 (100 % RDF + FYM @ 10 t ha -1 + Azospirillum @ 5<br />

kg ha -1 + PSB @ 5 kg ha -1 ) as shown in the figure.<br />
