The present research entitled “Effect of new generation herbicides on the growth and yield of lentil (Lens culinaris Medik.)” conducted during rabi seasonof 2023-24 at Research cum Instructional Farm, College of agriculture IGKV, Raipur, Chhattisgarh. The experiment was conducted in Randomized block design with 3 replication and 8 treatment viz, Pendimethalin (30% EC) 750 g a.i. ha-1 as PE, Imazethapyr (10% SL) 50 g a.i. ha-1 as PE, Pendimethalin (30% EC) 750 g a.i. ha-1 as PE fb Quizalofop-p-ethyl (5% EC) 100 g a.i. ha-1 at 20 DAS, Oxyfluorfen (23.5% EC) 150 g a.i. ha-1 PE fb Propaquizafop (10% EC) 100 g a.i. ha-1 at 20 DAS, Imazethapyr (10% SL) 50 g a.i. ha-1 at 20 DAS,Quizalofop-p-ethyl (5% EC) 100 g a.i. ha-1 at 20 DAS, Weedy check and Weed free check (Hand weeding twice at 20 & 40 DAS). Results revealed that growth attributing characters viz., plant height, number of branches plant-1, number of leaves plant-1, leaf area plant-1, dry matter accumulation, as well as seed yield, stover yield and harvest index were found to be maximum under hand weeding twice at 20 and 40 DAS followed by Oxyfluorfen (23.5% EC) 150 g a.i. ha-1 PE fb Propaquizafop (10% EC) 100 g a.i. ha-1 at 20 DAS. Minimum values of above characters were observed in weedy check.In terms of economics, maximum gross return and net return were fetched under hand weeding twice at 20 and 40 DAS followed by Oxyfluorfen (23.5% EC) 150 g a.i. ha-1 PE fb Propaquizafop (10% EC) 100 g a.i. ha-1 at 20 DAS,but maximum B: C ratio was fetched under Oxyfluorfen (23.5% EC) 150 g a.i. ha-1 PE fb Propaquizafop (10% EC) 100 g a.i. ha-1 at 20 DASand the lowest gross return, net return and B:C ratio were received under weedy check.
