Rice is an essential staple food that contributes significantly to global food security. Direct-seeded rice (DSR) offers advantages over traditional puddle-transplanted rice (PTR) in terms of water and labour savings. However, DSR faces significant weed management challenges that can affect yield. Herbicides have emerged as effective tools for weed management in DSR, with recommendations for using herbicide combinations and rotations to combat weed diversity and resistance. Field experiments was conducted in Varanasi (UP), India, to assess the effectiveness of post herbicides in weed management, yield attrubtes and yield in DSR. Nine treatments replicated thrice were tested using randomized complete block design (RBD). Based on the results of the current research, it can be infer that the post application of bispyribac sodium 20% + pyrazosulfuron 15% WDG with a non-ionic surfactant @ 52.50 g/ha, bispyribac sodium 20% + pyrazosulfuron 15% WDG with non-ionic surfactant @ 61.25 g/ha, and triafamone 20% + ethoxysulfuron 10% WG @ 66.5 g/ha sprayed after 16 days after sowing (DAS) exhibited the most favorable growth parameters and grain yield.
