Effect of different micronutrients on plant growth and yield of broccoli (Brassica oleracea var. Italica) Palam Samridhi

Abstract

A field experiment was conducted broccoli (Brassica oleracea var. Italica) cv. – Palam smaridhi” during rabi season of 2016-17 Horticulture Research farm, Department of Horticulture, Naini Agricultural Institute, SHUATS, Allahabad. The experiment laid out in Randomized Block Design (RBD) with three replications. The micronutrients (B, Mn and Zn) were applied at the rate of 2.5 kg (B), 3 kg (Mn), 2 kg (Zn) per hectare significantly increased the plant height (53.61 cm), number of leaves (25.23), Plant spread (54.51 cm), diameter of bud or head (17.81 cm), average bud weight of per plant (571.83 gm), yield ha-1 (134.05 q), vitamin c (92.34 mg), TSS (0Brix) (8.23) content, Plant fresh weight (897.00 gm), dry plant matter (96.48 gm), root weight (46.63 gm) and dry weight (12.63 gm) were maximum in treatment T5 and lowest in T0 (control). It is also concluded that treatment T5 (B + Mn +Zn) was found economically best in treatment of cost benefit ratio i.e. (1:3.47) followed by (1:2.99) with T7 (B + Mo + Mn + Zn).
