A field experiment was conducted at Jabalpur, Madhya Pradesh, during the rabi seasons of 2022-23 and 2023-24 to study the influence of different establishment methods and weed control treatments on weed dynamics and wheat yield. The experiment was laid out in a split-plot design with three replications, comprising four establishment methods in the main plots: zero tillage, zero tillage with chemical stale seedbed, conventional tillage, and conventional tillage with stale seedbed. Four weed control treatments were assigned to the subplots: clodinafop-propargyl + metsulfuron-methyl (60 + 4 g/ha) as post-emergence, mesosulfuron-methyl + iodosulfuron-methyl sodium (12 + 2.4 g/ha) as post-emergence, hand weeding at 20 and 40 days after sowing (DAS), and a weedy check. Among the establishment methods, conventional tillage with stale seedbed significantly reduced the total weed population and weed biomass, whereas zero tillage increased weed density and dry matter. Among the herbicidal treatments, the application of clodinafop-propargyl + metsulfuron-methyl (60 + 4 g/ha) effectively controlled the density and dry weight of both grassy and broadleaf weeds, resulting in 87.63% and 83.93% higher grain yield compared to the other weed control treatments during both years of the study.
