Abstract: The experiment was conducted at Horticultural Research Farm, College of Agriculture, RVSKVV, Gwalior (M.P.) during Rabi season 2018-19 and 2019-20. The treatments included combination of different bio-fertilizers and RDF. The experiment was laid out in randomized block design (RBD) with 15 treatments replicated thrice. I pooled, application of bio-fertilizer with different dose of fertilizers had significantly enhanced the yield and yield attributes viz., maximum equatorial diameter of bulb (6.95 cm), polar diameter of bulb (6.29 cm), fresh yield per plant (56.86 g), yield per plot (22.74 kg), yield per hectare (276.02 qt) and dry weight of bulb (31.49 g) were recorded under treatment T₁₅ – 100% RDF + Azospirillum + Azotobacter + PSB at 30, 60, 90 and 120 days after transplanting, respectively. This treatment, gave significantly higher qualitative yield (379.09 q ha^-1) and net returns of (Rs. 3,41,198) as well as maximum B: C ratio of 3:1 keeping the soil fertility sustainable for better yield of successive crop.
