A field study was conducted to assess the effect of different sole and ready-mix herbicides on weeds and productivity of summer greengram in Odisha,  during summer season of 2020 and 2021 at Agricultural Research Station, Chatabar, Faculty of Agricultural Sciences, IAS, SOADU, Bhubaneswar. Eight treatments, viz. pre-emergence application (PE) of pendimethalin 0.75 kg/ha at 1 day after sowing (DAS),  post-emergence application (PoE) of imazethapyr 75 g/ha at 20 DAS, pendimethalin + imazethapyr 0.75 kg/ha PE at 1 DAS, quizalofop-ethyl 50 g/ha PoE at 20 DAS,  fenoxaprop-p- ethyl 50 g/ha PoE at 20 DAS, sodium-acifluorfen 16.5% + clodinafop-propargyl 8% 245 g/ha PoE at 20 DAS, hand  weeding twice at 15 and 30 DAS and weedy check, were replicated thrice in the randomized block design.  Hand weeding twice at 15 and 30 DAS registered significantly lowest density and biomass of all categories of weeds as well as total weeds and it was closely followed by pendimethalin + imazethapyr (ready-mix) 0.75 kg/ha PE. Pendimethalin PE and imazethapyr PoE recorded at par value of density and biomass of grasses, broad-leaved and total weeds. Hand weeding twice at 15 and 30 DAS registered the highest seed yield (1076 kg/ha) of greengram along with higher yield attributing characters like number of pods/plant (29.23), seeds/pod (7.90) and number of branches/plant (8.88) and it was closely followed by pendimethalin + imazethapyr (ready-mix) 0.75 kg/ha PoE. Highest net return ( 39,809/ha) and return per rupee invested (2.12) was registered  with  pendimethalin + imazethapyr (ready-mix) 0.75 kg/ha PE.
