Effect of foliar application of different nutrients on growth and yield of wheat (Triticum aestivum L.) under sodic soil

Abstract

The present investigation entitled “Effect of foliar application of different nutrients on growth and yield of wheat (Triticum aestivum L.) under sodic soil” was carried out at main experiment station (MES) of Acharaya Narendra Dev University of Agriculture & Technology, Kumarganj, Ayodhya (U.P.). During rabi season - 2017-18. The experiment was laid in field condition with randomized block design and three replications. Seven treatments comprised of five different nutrients as zinc sulphate (0.5%) and (0.7%), boric acid (0.2%) and (0.4%) and potassium nitrate (0.1%) and (0.3%) applied as foliar application at 35 DAS of crop growth. A controlled set was also maintained. The observations were recorded as growth parameters at, 40, 60 and 90 DAS, yield and yield attributing traits were recorded at harvest. All the foliar application of nutrients increased the growth characters viz., plant height (cm), number of tillers per m2, dry weight plant was found significantly superior with foliar application of 0.7% zinc sulphate at all the stages of crop over control. Yield characters viz., length of spike (10.5cm), No. of grains per spike (45.10), no. of grains per plant (40.20), Grain yield/m2 (285), grain yield qha1 (28.50), test weight (38.26g) and harvest index (29.80%) were recorded significantly higher with foliar application of 0.7% zinc sulphate followed by foliar application of 0.3% of potassium nitrate over control.
