Effect of chemical weed management and sowing method practices in late sown wheat (Triticum aestivum L.)

Abstract

A field experiment was conducted during rabi seasons of 2015-16 and 2016-17 at Instructional Farm (SIF), Department of Agronomy, C S Azad University of Agriculture and Technology, Kanpur in alluvial tract of gangetic plains in Central part of Uttar Pradesh. The treatments consisted three sowing methods and five weed management practices. The experiment was laid out in split plot design with three replications. The results showed that plant height was increasing with increasing days after sowing in the relevant crop of wheat, respectively. The tallest plants were obtained in S3 : Cross sowing followed by S2 : Line sowing. The application of weed management practices on W4 : Two hand weeding (25 and 45 DAS) W2 : Clodinofop (60g ha-1) fb 2,4-D (500 g ha-1), significantly improved the growth and yields of Two hand weeding (25 and 45 DAS) followed by Clodinofop (60g ha-1) fb 2,4-D (500 g ha-1), amongst different cropping systems during the two years of experimentation.
