Abstract::Toclarifyimpactofherbicides onweedcontrol efficacyand wheat yieldunderdiferent tillage practicesof fields,thisstudy wasconducted touse two tilage practices:deep plowingandshallow rotary tilage.Various chemical herbicideswereappliedatthe three-leaf stageofwinter weeds before winter,follwedbyinvestigationsinto weeds numberat3Oand12Odaysafterapplicationandfinal wheatyieldatharvest.Theresultsshowed thatunder thesame tillagemode,treatment of diflufenican·flufenacet ⋅⋅ flurtamone 33% SC + isoproturon 50% SCexhibited the highest weedcontrol eficacy.When using thesameherbicide,deep plowing significantlyreduced weedsnumbercompared to shallow rotarytillage.Inthe deepplowingsystem,the highest wheat yield wasachieved with treatmentof diflufenican·flufenacet·flurtamone 33% SC + isoproturon 50% SC.Under shallow rotary tillage,treatment ofdiflufenican·flufenacet 35% SC + isoproturon 50% SC yielded the highest wheat production.Across all herbicides treatments,deep plowing consistentlyresultedinsignificantlyhigher wheatyieldsthanshalowrotarytillge.Therefore,implementing deepplowingandapplyingchemicalherbicidesatthethree-leafstage of winter weeds could efectivelycontrol weeds, enhance wheat yield,and ensure stable and increased wheat production in fields.
