Online Published on 28 October, 2024. Abstract An experiment was conducted at Agricultural Research Station, Mandor during two consecutive rainy (Kharif) seasons of 2021 and 2022 and subsequent Rabi season of 2021-22 and 2022-23 to optimize groundnut (Arachis hypogaea L.) production through diclosulam-based weed management and its residual effect on consecutive wheat crop. The findings disclosed that all the weed management treatment significantly reduced weed density and weed dry matter at 50 days after sowing (DAS) and increased yield attributes and pod yield of groundnut over weedy check. The highest weed control efficiency (WCE) was observed in thrice manual weeding at 25, 50 and 80 DAS/weed free (84.0%) followed by (fb) application of diclosulam 25 g/ha pre-emergence (PE) fb hand weeding at 30 and 60 DAS (79.2%). The maximum pod yield (2.03 t/ha) was recorded due to thrice hand weeding at 25, 50 and 80 DAS/weed free, which was at par with diclosulam 25 g/ha PE fb quizalofop-ethyl 50 g/ha PoE at 30 and 60 DAS, pendimethalin 1.0 kg/ha PE fb quizalofop-ethyl 50 g/ha PoE at 30 and 60 DAS, diclosulam 25 g/ha PE fb hand weeding at 30 and 60 DAS and diclosulam 20 g/ha fb hand weeding at 30 and 60 DAS. Results further indicate that highest net returns and B: C ratio were recorded in pendimethalin1.0 kg/ha PE + quizalofop-ethyl 50 g/ha PoE at 30 and 60 DAS followed by diclosulam 25 g/ha PE + quizalofop-ethyl 50 g/ha PoE at 30 and 60 DAS.
