A field experiment was conducted during kharif 2016 at College of Agriculture, Hassan, University of Agricultural Sciences, Bengaluru to evaluate different pre and post emergent herbicides on growth and yield of potato (Solanum tuberosum L.) the soil of experimental site is red sandy loam in texture, neutral in reaction and medium in available nitrogen, phosphorus and potassium. The experiment was laid out in a RCBD with seven treatments replicated thrice. The higher yield was obtained in weed free check, while among the herbicide treatments fenoxaprop–p-ethyl 54 g a.i. ha-1 as early post emergent recorded between components such as number of tubers per plant (r= 0.977*), and tuber weight per plant (r= 0.977*) with tuber yield. The correlation between growth and yield attributes of potato was positively correlated while significant negative correlation between yield and weed density and dry weight.
