A field experiment was conducted during winter (Rabi) season of 2019-20 at Instructional Farm, Department of Agronomy, College of Agriculture, JAU, Junagadh, Gujarat, India, to study the effect of different weed management treatments on weeds, yield attributes and yield of chickpea. The experiment comprised of twelve treatments laid out in randomized block design with three replications. Significantly higher plant height, number of branches / plant, number of pods/plant, seed yield and stover yield, were recorded with pre-emergence application (PE) of pendimethalin 900 g/ha followed by (fb) post-emergence application (PoE) of sodium-acifluorfen + clodinafop-propargyl 80 + 165 g/ha ready-mix (RM) at 40 DAS and hand weeding (HW) twice at 20 and 40 days after seeding (DAS) as they effectively minimized the weed biomass and lowered weed index with higher weed control efficiency. The highest net return and B:C ratio were recorded with pendimethalin 900 g/ha PE fb sodium-acifluorfen + clodinafop-propargyl 80 + 165 g/ha (RM) PoE at 40 DAS followed by alachlor 750 g/ha PE fb sodium-acifluorfen + clodinafop-propargyl 80 +165 g/ha (RM) PoE at 40 DAS and HW twice at 20 and 40 DAS.
