ABSTRACT    A field study was undertaken to investigate the influence of stale seedbed on weed dynamics and yield performance of wheat at farm area, MNS-University of Agriculture Multan. Current study was carried out under RCBD with three replications. This experiment have eight treatments viz: one till + no herbicide, one till + glyphosate 48% SL at 711 a.i mL/ha, one till + paraquat 20% SL at 494 a.i mL/ha, one till + atlantis (mesosulfuron-methyl and iodosulfuron-methyl sodium) 6% WG at 15 a.i g/ha, one till + glyphosate at 48% SL 356 a.i mL/ha + paraquat 20% SL at 247 a.i mL/ha, one till + glyphosate 48% SL at 356 a.i mL/ha followed by atlantis 6% WG at 7.5 a.i g/ha, one till + paraquat 20% SL at 247 a.i mL/ha followed by atlantis 6% WG at 7.5 a.i g/ha, one till + glyphosate 48% SL at 237 a.i mL/ha + paraquat 20% SL at 165 a.i mL/ha followed by atlantis 6% WG at 5 a.i g/ha. Cronopus didymus and Chenopodium album density was maximum in one till + no herbicide while, minimum was observed in one till + glyphosate + paraquat followed by atlantis treatment at 45 DAS and 60 DAS, respectively. While maximum dry weight of weeds was recorded at harvest. Maximum thousand grain weight (31.88 g) and grain yield (4.65 tons/ha) were recorded in one till + glyphosate + paraquat followed by atlantis. It can be concluded that adoption of stale seedbed technology and post emergence application showed a check on weeds growth till 60 DAS to maximize the economical wheat yield. There is a need to explore weed management by combining chemical and mechanical weed control under stale seedbed, sole and in combination along with varying cropping systems under climate change scenario to reduce the reliance on herbicides. © 2020 Department of Agricultural Sciences, AIOU
