21. Response of broccoli to foliar application of zinc and boron concentrations
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.
