Abstract: An experiment was conducted at agronomy research farm on silty loam soil, having pH 8.6, EC 0.36 dSm-1, organic carbon 0.31%, available N, P and K 178.0, 14.5 and 231.5 kg ha-1, respectively. Experiment consisted of 9 treatment combinations together three levels of nitrogen viz. 80, 120 and 160 kg N ha-1 and three herbicide treatments viz. pendimethalin fb 2, 4-D (1 + 0.5 kg a.i. ha-1),clodinafop + metsulfuron (0.06 + 0.004 kg a.i. ha-1) and sulfosulfuron (0.025 kg a.i. ha-1) result reveal that All the herbicides applied as post-emergence, except pendimethalin. All the growth and yield contributing characters viz. plant height,, Leaf Area Index, number of effective shoots, spike length, number of grain spike-1 as well as test weight of grain were significantly higher in 160 kg N ha-1 and clodinafop + metsulfuron (0.06 + 0.004 kg ha-1). With respect to economics 160 kg N ha-1 combined with clodinafop + metsulfuron (0.06 + 0.004 kg ha-1).
