摘要

The efficacy of diclosulam herbicide in managing weeds and improve groundnut yield was tested in this study on weed management in groundnut (Arachis hypogaea L.). The diclosulam pre-plant incorporation (PPI) and pre-emergence application (PE) significantly reduced the sedges density. The diclosulam 27 g/ha PE followed by (fb) hand weeding (HW) at 50 days after seeding (DAS) recorded highest weed control efficiency (80.44%) and lowest (92) weed density (number /m2) at 80 DAS. Number of groundnut podsper plant and pod yield was significantly higher with diclosulam 27 g/ha PE fb) HW at 50 DAS and also gave the highest net return of <= 1,07,335/ha and B:C ratio of 2.32 followed by hand weeding twice at 30 DAS and 50 DAS and diclosulam 27 g/ha PPI fb HWat 50 DAS.
