A field investigation was carried out to study the impact of nitrogen levels and herbicide application on wheat growth and yield. Two levels of nitrogen i.e. 100 and 125 kg ha-1 (N1, N2) were randomized in main plots, whereas different doses of herbicide i.e. weedy control (D0), Topik @ 200 and 300 g ha-1 (D1, D2) were superimposed on each nitrogen level as sub plot effect. The results revealed that maximum yield was obtained by the application of Topik @ 300 g ha-1 which was attributed to the more effective control of weeds that reduced the competitive effect of weeds on crop plants. It was concluded that the weed free plots resulted in profused tillering and increased number of spikelets per spike that contributed positively towards high yield.
