Rhizobium involve in symbiotic biological nitrogen fixation; survival in soil, Rhizosphere colonization, infection and nodule development and energy transformation during nitrogen fixation in root nodules. The experiment was conducted during kharif, 2024 at new experimental cum demonstration field, SVIAg, SVVV, Indore. The experiment consists of nine treatments. The treatments were replicated three times in Randomized Block Design which consists, the use of RDF, Rhizobium as bio-inoculants and various levels of molybdenum. The treatment includes T₁: Absolute control, T₂:  RDF (20:40:40 kg NPK ha^-1), T₃: RDF + Rhizobium, T₄: RDF + 200 gm ha^-1 Mo, T₅: RDF + 400 gm ha^-1Mo., T₆: RDF + 600 gm ha^-1 Mo, T₇: RDF +Rhizobium + 200 gm ha^-1 Mo, T₈: RDF +Rhizobium + 400 gm ha^-1 Mo and T₉: RDF +Rhizobium + 600 gm ha^-1 Mo. Treatment with application of RDF + Rhizobium + 600 gm ha^-1 Mo recorded highest plant height (58.83 cm), no. of leaves plant^-1 (36.06), no. of branches plant^-1 (10.01), leaf area plant^-1 (12.83), no. of nodules plant^-1 (63.33), dry matter plant^-1 (9.04 g) and no. of pods plant^-1 (35.00), yield attributing characters viz., maximum no. of pods plant^-1 (35.00), pod yield plant^-1 (19.60 g), seed yield plant^-1 (15.51 g) at harvest while the values were at par with those of treatment with application of RDF + Rhizobium + 400 gm ha^-1 Mo. In a similar vein, noticeably higher seed yield (9.88 q ha^-1), straw yield (16.34 q ha^-1) and biological yield (26.23 q ha^-1) was found in same treatment.
