Effect of crop-establishment methods and weed-management options on weed and yield of wheat

Abstract

A field experiment was conducted during Rabi season of 2012-13 and 2013-14 at GBPUAT, Pantnagar to study the effect of tillage and weed management practices on weed control and yield of wheat under rice- wheat cropping system. Zero tillage (ZT) in wheat was more beneficial as it recorded higher yield with lower cost than convention tillage (CT) in wheat. Among the weed management options, post-emergence application of pinoxaden 50g/ha fb metsulfuron-methyl (MSM) 4g/ha resulted in lowest density and biomass of total weeds, which was statistically at par with readymix combination of clodinofop 60g + MSM 4g/ha. The post- emergence application of pinoxaden 50g/ha fb MSM 4g/ha followed by readymix combination of clodinofop 60g + MSM 4g/ha recorded highest weed control efficiency (WCE) and grain yield.
