Abstract

An experiment to study the response of broccoli to foliar application of zinc and boron concentrations was carried out under field condition during 2013-14 at Horticulture Research Farm, The University of Agriculture Peshawar. Zinc at the rate of (0, 0.25, 0.5, and 1.0%) and boron at the rate of (0, 0.25, 0.5, and 1.0%) were applied as a foliar spray using Randomized Complete Block Design with three replication. Maximum plant height (40.49 cm) and number of leaves plantˉ1 (13.08), were noted at 0.5 % Zn, while Zn @ 1% resulted in maximum leaf weight (9.66 g) and maximum number of curd plant-1 (9.17. Regarding B maximum plant height (39.31cm) was observed with 0.25% boron while minimum (32.30 cm) in plants sprayed with 1% boron. B @ 0.5% resulted in maximum number of leaves plantˉ1 (12.83). Maximum leaf weight (10.17 g) and number of curds plantˉ1 (8.41) were noted at 1 % boron. Among various treatments used zinc and boron levels at the rate of 0.5%, showed better result in most of the growth and yield parameters.
