Weed management in direct-seeded rice (Oryza sativa) in central India

A field experiment was conducted in a split-plot design with 3 replications at Research Farm, College of Agriculture, Jawaharlal Nehru Krishi Vishwa Vidyalaya, Jabalpur (Madhya Pradesh), during the rainy (kharif) season 2019, to evaluate performance different herbicides direct-seeded rice (Oryza sativa L.). The comprised 2 main plots, viz. rainfed and irrigated, 8 weed-control treatments, bispyribac sodium 25 g/ ha, fenoxaprop-p-ethyl 60 g/ha, + penoxsulam 26.7 cyhalofop 135 metsulfuron-methyl chlorimuron ethyl 4 triafamone ethoxysulfuron 40 20 hand-weeding twice weedy check, subplots. dominant weeds associated experimental were mainly monocot, jungle [Echinochloa colona (L.) Link] Bermuda grass [Cynodon dactylon Pers.], sedge, nutgrass [Cyperus iria (L.)], dicot weed such as sissoo spinach [Alternanthera sessilis R. Br. ex DC.]. results indicated that, post-emergence application g/ha days after sowing (DAS) recorded highest efficiency (87.75%), followed by g/ha. Higher grain yield (3.09 t/ ha) weed-free treatment which par
