ABSTRACT: The experiment was conducted during Rabi season of 2013-14 to study the efficacy of different herbicides alone and their combination to control weeds in potato crop. Among the different herbicides studied pre-emergence application of atrazine @250 g/ha alone have been found more efficient in controlling both monocot and dicot weeds with higher weed control efficiency (99.1%) as compared to atrazine @125 g/ha with metribuzin@175 g/ha as pre-emergence and with paraquat@35 g/ha as post-emergence. The maximum potato yield, nutrient uptake by potato crop and minimum nutrient uptake by weeds was recorded in weed free (425.8q/ha) while pre-emergence application of atrazine @250 g/ha gave higher significant results followed by pendimethalin@1000g/ha as pre-emergence. However, maximum nutrient uptake by weeds was recorded with weedy check. The highest benefit: cost ratio was noticed in atrazine @250 g/ha pre-emergence (2.72) compared to other herbicides and conventional weed management practices.
