Abstract: The field experiment was conducted during Rabi season of 2016-17 at the Horticulture Research cum Instructional farm, BTC CARS, Bilaspur (C.G.). The treatments consisted of eleven combination of different agro input management practices viz., treatments 100 % RDF (Control) (T₁), 75 % RDF + 25 % N through FYM (T₂), 75 % RDF + 25 % N through VC (T₃), 50 % RDF + 50 % N through FYM (T₄), 50 % RDF + 50 % N through VC (T₅), 125% RDF (T₆), 100 % RDF + 25% N through FYM (T₇), 100 % RDF + 25% N through VC (T₈), 100 % RDF + 25% N through FYM + Azotobacter @ 2 kg ha^-1+PSB @ 2 kg ha^-1 (T₉), 100 % RDF + 25% N through VC+ Azotobacter @ 2 kg ha^-1+PSB @ 2 kg ha^-1 (T₁₀), 100 % from organic FYM+VC+AZ+PSB (T₁₁). The significantly maximum and minimum head Formation was recorded 95.01(%) T₂ and 78.41 (%) T₁₁ at harvest. Maximum head height was recorded 60 DAT and time of harvest are 16.91cm and 20.79 cm under treatment T₂ minimum head height was recorded 12.43 cm and 14.71cm under treatment T₃ and T₇. Maximum head diameter was recorded 60 DAT and time of harvest are 42.65 cm and 46.37 cm under treatment T₂ minimum head diameter was recorded 24.90 cm and 32.69 cm under treatment T₈ and T₄.
