Effect of different herbicides and planting techniques on yield and yield components of in late sown wheat (Triticum aestivum L.)

Abstract

An experiment was conducted at C S Azad University of Agriculture and Technology, Kanpur District of Uttar Pradesh during rabi seasons of 2015-16 and 2016-17 to find out the effect of different herbicides and planting techniques on yield and yield components of in late sown wheat (Triticum aestivum L.). The treatments consisted three planting techniques and five weed management practices. The experiment was laid out in split plot design with three replications. Planting method plays an important role in the placement of seed at proper depth, which ultimately affects crop growth. The selection of suitable planting method for wheat is dependent upon the time of planting, availability of soil water at planting time, amount of residue in the field. 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 Cross sowing followed by Line sowing. The application of weed management practices on Two hand weeding (25 and 45 DAS) and Clodinofop (60g ha-1) fb 2,4-D (500 g ha-1), significantly improved the yield and yield components of Two hand weeding (25 and 45 DAS) followed by Clodinofop (60g ha-1) fb 2,4-D (500 g ha-1), amongst different treatments during both year.
