INFLUENCE OF WEED MANAGEMENT PRACTICES ON WEED DYNAMICS AND YIELD OF DRUM SEEDED RICE UNDER PUDDLED CONDITION

Field experiment was conducted at Agricultural Research Station, Thirupathisaram during Rabi season (November-March) of 2017-2018 to evolve suitable weed management practices for drum seeded rice under puddled condition. Among the chemical treatments tried, the application of pretilachlor @ 0.75 kg a.i ha-1 on 8 DAS as PE fb bispyribac sodium @ 25 g a.i ha-1 on 20 DAS as Eearly Post Emergence (EPoE) recorded significantly lowest total weed density, total dry weight and highest weed control efficiency when compared to other treatments. Higher grain yield (6436 kg ha-1) and straw yield (7210 kg ha-1) was recorded in the application of pretilachlor @ 0.75 kg a. i ha-1 on 8 DAS as PE fb bispyribac sodium @ 25 g a.i ha-1 on 20 DAS as EPoE apart from weed free check.
