Effect of Foliar Application of Zinc and Boron on Growth and Yield Components of Wheat

A field experiment entitled "Effect of foliar application of Zinc and Boron on growth and yield components of wheat" was conducted at Bacha Khan Agricultural Research Farm (BARF), Bacha Khan University, Charsadda during the winter season 2015-16.The aim of the experiment was to investigate the effect of foliar application of Zinc and Boron on growth and yield components of wheat.Treatments included zinc (as zinc sulfate 25g/L -1 ), boron (as boric acid 20g/L -1 ) and zinc plots boron (as zinc sulfate and boric acid 25 g/L -1 and 20g/L -1 , respectively).Water spray and no spray were used as control.The experiment was planned according to randomized complete block design (RCBD) consisting of three replications.Seed was applied at the rate of 100kg ha -1 .The recommended dose of NPK was applied at the rate of 60, 75 and 0kg ha -1 respectively.It was revealed from that the results of the experiments that foliar application of zinc + boron in wheat showed significant variation for all of the parameters recorded during the course of study except days to emergence.In case of interaction, maximum plant height (103cm), grains spike -1 (45), 1000 grains weight (37g), grain yield (5966.67kg ha -1 ), biological yield (19059kg ha -1 ) and harvest index (31.30%)were recorded with foliar application of zinc + boron.Maximum plant height (102cm), grains spiek -1 (44.6), 1000 grains weight (36g), grain yield (5743kg ha -1 ), biological yield (14707.7kg ha -1 ) and harvest index (39.06%) were recorded with foliar application of zinc.
