Herbicide combinations for control of complex weed flora in wheat

A field experiment was conducted in 2014 and 2015 to find out the effect of herbicides on weed dynamics and productivity of wheat under Jharkhand situation. Two hand weeding performed in wheat crop at 30 and 60 DAS recorded significantly reduced weed density and weed dry matter of broad-leaf, grassy, sedges and total weeds at 30 and 60 DAS with WCE of 94.3 and 94.2%, respectively and was similar to post-emergence application of clodinafop 0.06 kg/ha and pre-emergence application of pendimethalin + metribuzin 1.0 kg/ha + 0.175 kg/ha. This resulted in maximum total and effective tillers, grain (3.08 t/ha) and straw (5.37 t/ha) yield and net return (‘ 32,019.00 and B:C ratio (1.33) compared to other herbicides application.
