Abstract The field experiment was conducted at Agronomy Department Farm, College of Agriculture, Dapoli, during Kharif (rainy) seasons 2016 and 2017 to study the effect of established by different methods of rice establishment on weeds. The field experiment was laid out in a strip plot design comprising of twenty five treatment combinations replicated thrice. The horizontal strips comprised five rice establishment methods, viz. sowing of dry seeds by drum seeder at onset of monsoon, sowing of sprouted seeds (Rahu) by drum seeder in puddled field, broadcasting of sprouted seeds (Rahu) in puddled field, system of rice intensification (SRI) method and conventional transplanting. The vertical strips consisted five weed management practices, viz. need based two hand weedings at 20/30 and 40/60 DAS/DAT, pre-emergence application of oxadiargyl 80 WP 100 g/ha + 1 hand weeding at 20/30 DAS/DAT, pre-emergence application of oxadiargyl 80 WP 100 g/ha + 1 hand weeding at 40/60 DAS/DAT, pre-emergence application of oxadiargyl 80 WP 100 g/ha + post-emergence application of Almix 20 WP 4 g/ha and unweeded control. SRI method with two hand weedings carried out at 20 and 40 DAT recorded highest grain and straw yield of rice and lowest weed density and dry weight of weeds as compared to remaining treatment combinations during both the seasons.
