Abstract: A field experiment was conducted at Vegetable Research Field, Central Orcherd, Department of Horticulture, Allahabad School of Agriculture, Sam Higginbottom Institute of Agriculture Technology and Sciences Allahabad (U. P.) India to find out the effect of different micronutrient on vegetative growth of broccoli (Brassica oleracea var. Italica) cv. Green Magic during rabi season 2015-16. The experiment was laid out in Randomized Block Design (RBD) with 10 treatments and each replicated thrice. There were four treatment B, Mo, Mn and Zn micronutrients which applied @ of (3:0.5:2:2.5 kg/ha) in plot single and combination during season. Results of different micronutrients application significantly influenced the bud or head diameter over control. The maximum bud diameter 18.02 cm was recorded with T₅ (B + Mn +Zn) followed by 16.22 cm in T_{8 (}B +Zn) and T₇ (B + Mo + Mn + Zn) i.e. 16.87 cm, which were significantly higher than other treatment. The treatment T₅ (B + Mn + Zn) had significantly the highest bud weight (511.50 gm) followed by T₇ (B + Mo + Mn +Zn) is 343.00 gm. Lowest bud weight 198.02 gm was observed in T₀ (control). Maximum number of frouds (18.32) was observed in T₅ (B + Mn + Zn) followed by 15.89 T₄ (Mo+B) and minimum (12.98) were found in T₀ (control). The treatment T₅ (B + Mn + Zn) had significantly more yield per hectare (138.58 q/ha followed bye T₇ (B + Mo + Mn +Zn) 116.23 q/ha. than other treatment. The yield of treatment T₂ (Mo) and T₃ (Mn) was almost similar (98.03q/ha and 98.99 q/ha) respectively. The treatment T₀ (control) recorded lowest yield per hectare (72.98 q/ha).
