Abstract
A field experiment was conducted during the Kharif season of 2015 to 2017 for three years at Agricultural Research Station, Vadgaon Maval, Pune, Maharashtra to find out the efficacy of different weed control methods on dry direct-seeded rice and its economics. Pretilachlor 0.450 kg/ha as pre-emergence application (PE) at 2–3 days after sowing (DAS) followed by (fb) azimsulfuron 0.035 kg/ha as post-emergence application (PoE) at 25 DAS effectively managed weeds in dry-DSR and gave the higher grain yield (5.62 t/ha), net returns (’ 82777/ha), higher B:C ratio (2.8) with lower weed index (2.78) and higher weed control efficiency (87.7%).
