Abstract A field experiments was conducted during winter seasons of 2010–11 and 2011–12 at Agricultural Research Farm, Banaras Hindu University, Varanasi to study the effect of herbicide mixtures and differential rate of nitrogen application of economics of wheat under Indo-Gangetic Plains of eastern Uttar Pradesh. The experiment was laid out in factorial randomized complete block design and replicated thrice, having three factors. First factor comprised of three herbicides viz. weedy check, sulfosulfuron + metsulfuron [32 g ha−1] and carfentrazone [10 g ha−1] + fenoxaprop-p-ethyl [100 g ha−1], whereas, second and third factors comprised of two nitrogen rates (120 kg N ha−1 and 160 kg N ha−1) and three times of nitrogen application (50% basal + 50% CRI, 50% basal + 25% CRI + 25% flowering and 33.3% basal + 33.3% CRI + 33.3% flowering), respectively. Significantly highest grass return, net return and benefit cost ratio were observed with application of sulfosulfuron + metsulfuron [32 g ha−1]. Increasing nitrogen level from 120 to 160 kg ha−1 significantly increased the economic return. Application of nitrogen in three split (50% basal + 25% CRI + 25% flowering) proved significantly in term of grass return, net return and benefit cost ratio over other split application of nitrogen.
