Influence of Zinc on Zinc Use Efficiency in Broccoli in Mid Hills of Himachal Pradesh

The present investigationt was carried out during rabi season of 2020-21 at the Experimental Research Farm of the Department of Vegetable Science, Dr. YS Parmar University of Horticulture and Forestry, Nauni, Solan, Himachal Pradesh to find out the effect of zinc on the nutrient use efficiency in Broccoli cv. (Palam Samridhi). The experiment was carried out in a Randomized Complete Block Design (RCBD) with three replications. Manures, synthetic fertilizers and micronutrients were replicated thrice in the form of nine treatments. The observations were recorded on marketable yield per plot (kg), Zn content in soil (mg kg-1), Zn uptake in plants (kg ha-1) and zinc use efficiency (%). The treatment combination having 50% N through vermicompost + 50% N through urea + RD of PK and FYM + ZnSO4 @15 kg/ha produced best results for all the parameters studied.
