Abstract
A field experiment was conducted during 2014–15 and 2015–16 to study the efficacy of herbicides for control of diverse weeds in barley. Herbicides were sprayed alone or in combinations. The highest grain yield (5.54–6.07 t/ha) was recorded in weed-free treatment which was at par with isoproturon 750 g/ha + 2,4-D 500 g/ha and pinoxaden 40 g/ha + carfentrazone 20 g/ha. Uncontrolled weed competition caused an average 8–54% yield reductions compared to weed-free treatment. The magnitude of net returns and the benefit-cost ratio was higher with the applications of isoproturon 750 g/ha + 2,4-D (Na salt) 500 g/ha, pinoxaden 40 g/ha + carfentrazone 20 g/ha, isoproturon 750 g/ha + metsulfuron 4 g/ha and pinoxaden 40 g/ha followed by metsulfuron 4 g/ha and in weed-free.
