Studies on yield of broccoli (Brassica oleracea var. italica) cv. green magic as influenced by different micronutrients

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 T8 (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).
