Abstract: A field experiment was conducted at Instructional cum Research Farm, Indira Gandhi Krishi VisHand weedingavidyalaya, Raipur (C.G.) during mansoon crop 2021 and 2022. The soil of experimental field was neutral in reaction, medium in organic carbon and low in available nitrogen, low in available phosphorus and high in available potassium. Experiment was laid out in randomized block design with three replications, consisted of T1-Imazethapyr 10 % SL (Dose-55 g a.i. ha-1), T2- Fluazifop-p-butyl 13.4% w w-1 (Dose-250 g a.i. ha-1), T3-Propaquizafop 2.5% w w-1 (weight per weight) + imazethapyr 3.75 % w w-1 ME (ready mix) (Dose-83.3g a.i. ha-1), T4- Acifluorfen-sodium 16.5% EC + clodinafop-propargyl 8% EC (ready mix) (Dose-210 g a.i. ha-1), T5- Fomesafen 11.1% w w-1 + fluazifop-p-butyl 11.1% w w-1 (ready mix) (Dose-440 g a.i. ha-1), T6-Hand weeding twice at 20 and 40 DAS (Days after sowing) , T7- Weed free (Hand weeding at 20, 40 and 60 DAS) and T8- Unweeded check. The weeds of the experimental site was dominated with grasses like Echinochloacolona, Dinebraretroflexa, broad leaves like Parthenium hysterophorus, Celosia argentea, sedge like Cyperus sps. and other weeds. Results revealed that all the yield attributes and yield was highest in fomesafen 11.1% w w-1 + fluazifop-p-butyl 11.1% w w-1 (ready mix) (Dose-440 g a.i. ha-1) (T5) which was at par with propaquizafop 2.5% w w-1 + imazethapyr 3.75 % w w-1 ME (ready mix) (Dose-83.3g a.i. ha-1)(T3) and acifluorfen-sodium 16.5% EC + clodinafop-propargyl 8% EC (ready mix) (Dose-210 g a.i. ha-1)(T4). Similar ways, weed density was also significantly reduced in these treatments to others. However, higher WCE (Weed control efficiency) was noticed in this treatment than unweeded check.
