Abstract
The conventional use of the same post-emergence herbicides repeatedly may result in poor management of the early weed flush in wheat under zero-tilled (ZT) condition. This may hasten development of herbicide resistant weeds as well. In this study, a possible weed management has been envisaged in ZT and conventional till (CT) wheat during 2013-14 and 2014-15 using tillage and weed control treatments. It was observed that ZT caused a considerable reduction in the population of narrow-leaved, broad-leaved and total weeds compared to CT. Among the herbicides, sulfosulfuron at 25 g ha-1 + metsulfuron methyl at 4 g ha-1 and clodinafop at 60 g ha-1 + carfentrazone ethyl at 20 g ha-1 were promising and it has an edge over other for reduction in weed population and dry weight. The weed control efficiency (WCE) was also higher in ZT treatments than the conventional treatments in both the years. Application of sulfosulfuron at 25 g ha-1 + metsulfuron methyl at 4 g ha-1 and clodinafop at 60 g ha-1 + carfentrazone ethyl at 20 g ha-1 as post-emergence recorded higher WCE. Similarly, ZT with sulfosulfuron at 25 g ha-1 + metsulfuron methyl at 4 g ha-1 and clodinafop at 60 g ha-1 + carfentrazone ethyl at 20 g ha-1 as post-emergence recorded significantly higher wheat crop growth parameter viz. plant height, number of tillers, and dry matter accumulation in both the years. The treatments were comparable with weed free check and recorded higher wheat crop growth. The highest grain and straw yield of wheat was recorded in ZT and it was significantly higher than CT in both the years. Weeds were found to reduce the grain yield significantly. The highest grain yield was recorded in weed free check followed by sulfosulfuron at 25 g ha-1 + metsulfuron methyl at 4 g ha-1 and clodinafop at 60 g ha-1 + carfentrazone ethyl at 20 g ha-1. The B: C ratio was higher with, sulfosulfuron at 25 g ha-1 + metsulfuron methyl at 4 g ha-1 under ZT which was significantly higher than UWC.
