Abstract:
A field experiment was conducted at College Farm, College of Horticulture, Sardarkrushinagar Dantiwada Agricultural University, Jagudan, Gujarat during the Rabi season of the year 2019-20 and 2020-21 to study the effect of different micronutrients and their methods of application on growth, yield and quality of broccoli (Brassica oleracea var. italica) cv. Palam Samridhi. The experiment was laid out in Randomized Block Design with Factorial concept comprising of two factors. The first factor was micronutrients (C) with seven levels viz., C1- B, C2 – Zn, C3 – Fe, C4 – B + Zn, C5 – B + Fe, C6 – Zn + Fe and C7 – B + Zn + Fe and the second factor was methods of application (M) i.e., M1- soil application, M2- single spray of micronutrients at 25 DATP and M3- two sprays of micronutrients at 25 and 50 DATP. The treatments were replicated thrice. The individual effect of micronutrients and their method of application as well as their interaction effect on growth and yield of broccoli cv. Palam Samridhi was recorded. The results indicate that effect of micronutrient using B + Zn + Fe (C7) treatment was the most effective treatment in all studied traits. Method of micronutrients application (M3) two spray of micronutrients at 25 and 50 DATP was found superior for growth and yield parameters except plant height (cm) at harvest, number of leaves per plant at harvest and number of sprouts per plant at harvest. The interaction effect of micronutrients and their methods of application C7M3 i.e., two spray of B @ 100 ppm + Zn @ 100 ppm + Fe @ 100 ppm at 25 and 50 DATP were found significant for all parameters of growth and yield, except sprout weight (g) per plant. Thus, from the present investigation it could be concluded that for successful cultivation of broccoli in North Gujarat two foliar applications of micronutrients i.e., B @ 100 ppm + Zn @ 100 ppm + Fe @ 100 ppm at 25 and 50 DATP along with RDF (120:80:80 NPK) is beneficial for optimum growth and higher yield.
