Abstract: A field experiment was conducted during Rabi season of 2015 at Vegetable Research Farm, Department of Horticulture, Udai Pratap College, Varanasi. The experiment consisted 16 treatment combinations viz. T₁ - N+P+K (100% Recommended Full Does), T₂ -75% N+P+K+25% Azotobacter, T₃ -50% N+P+K+50% Azotobacter, T₄ -25% N+P+K+75% Azotobacter, T₅ - N+75%P+K+25% PSB, T₆ - N+50%P+K+50% PSB, T₇ - N+25%P+K+75% PSB, T₈ -75%N+75%P+K+25%, T₉ -50%N+50%P+K+50% Azotobacter+50%PSB, T₁₀ -25%N+25%P+K+75% Azotobacter+75%PSB, T₁₁ -75%N+50%P+K+25% Azotobacter+50%PSB, T₁₂ -50%N+75%P+K+50% Azotobacter+25%PSB, T₁₃ -25%N+50%P+K+75% Azotobacter+50%PSB, T₁₄ -25%N+P+K+75% Azotobacter+25%PSB, T₁₅ -75%N+25%P+K+25% Azotobacter+75%PSB and T₁₆ -50%N+25%P+K+50% Azotobacter+25%PSB Azotobacter+25% PSB, which was laid out in randomized block design (RBD) with three replications. The result revealed that the application of 50:45:100 kg NPK/ha and inoculation of field with 1.25 ± 0.62 kg/ha Azotobacter and PSB significantly recorded the higher bulb yield of 303 q/ha.
