Field trial was conducted during Rabi 2015-2016 at Udaipur to find out an appropriate herbicidal recommendation to augment wheat productivity. The experiment consisted of thirteen treatments (pendimethalin 750 g/ha, sulfosulfuron 25 g/ha, metribuzin 210 g/ha, clodinafop 60 g/ha, pendimethalin fb sulfosulfuron at 1000 + 18 g/ha, pendimethalin + metribuzin at 1000 + 175 g/ha, sulfosulfuron + metsulfuron 30 + 2 g/ha, pinoxaden + metsulfuron 60+4 g/ha, mesosulfuron + iodosulfuron at 12 + 2.4 g/ha, clodinafop + metsulfuron at 60 + 4 g/ha, one hand weeding at 30 DAS, two hand weedings at 30 and 45 DAS, weedy check) were tested in a randomized block design in three replications. The results revealed that the mixed population of weeds comprising broad-leaf and grassy was significantly controlled by applying the herbicide mixtures than their alone applications. The sulfosulfuron + metsulfuron mixture resulted in minimum density and dry matter of weeds and NPK uptake by them. The simultaneous increase in NPK uptake by crop by applying this treatment resulted in significantly higher wheat grain yield and nets returns, though the yield and net returns were at par to that of mesosulfuron + iodosulfuron.
