A field experiment was conducted during three consecutive Kharif seasons (2020, 2021 and 2022) at Agricultural Research Station, Kota, Rajasthan, India to identify most effective post-emergence herbicides to managing weeds and improve greengram productivity. The experiment was laid out in Randomized Block Design with three replications and eight treatments. The weed free recorded minimum weed density and biomass, higher weed control efficiency, maximum and significantly higher growth, yield attributes and yields followed by hand weeding twice. Amongst herbicides, post-emergence application (PoE) of fomesafen + fluazifop-p-butyl  220 g/ha recorded lower weed density and biomass, higher weed control efficiency, maximum and significantly higher greengram growth, yield attributes and yields being at par with propaquizafop + imazethapyr 33.3 g/ha + 50 g/ha PoE and sodium-acifluorfen + clodinafop-propargyl 140 g/ha + 70 g/ha PoE over rest of the treatments. Maximum and significantly higher net returns and B:C ratio were also recorded with propaquizafop 33.3 g/ha + imazethapyr 50 g/ha PoE which was at par with fomesafen + fluazifop-p-butyl 220 g/ha PoE and sodium-acifluorfen 140 g/ha + clodinafop-propargyl 70 g/ha PoE.
