Abstract: 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. Application of Fenoxaprop–p-ethyl 54 gm a.i. ha-1 as early post emergent at 20 DAP recorded significantly higher number of tubers plant-1 (4.30), tuber weight plant-1 (250.50 g) and tuber yield (19.77 t ha-1) which was on par with Quizalofop–p-ethyl (4.07, 247.37 g and 18.93 t ha-1, respectively) except weed free check. Among herbicide treatments, higher gross returns, net returns and BC ratio were realized in treatment T3 i.e.,Fenoxaprop–p-ethyl 54 g a.i. ha-1 as early post emergent (₹. 1,97,667 ha-1, 1,39,622 ha-1and 3.41).Whereas lower gross returns, net returns and BC ratio were realized in weedy check (₹. 1,40,000 ha-1, 83, 408 ha-1 and 2.47).
