A field experiment was conducted during kharif season of 2014 at Dr. N. E. Borlaug Crop Research Centre, Pantnagar to assess the effect of different chemical and non-chemical methods of weed control on the weed dynamics of aerobic rice under irrigated ecosystem. Lowest weed density as well as weed dry matter at 25 days stage was found in plots treated with pendimethalin @ 1.25 kg/ha + hand weeding (HW) at 25 days after sowing (DAS) followed by wheat mulch straw (4t/ha) followed by (fb) fenoxaprop @ 60 g a.i/ha. Weed management practices along with pendimethalin @ 1.25 kg /ha fb HW (25 DAS) achieved significant control of weeds, high weed control efficiency (WCE) of 93.3 %. Among non - chemical methods of weed control, Sesbania co-culture fbconoweeder (25 DAS) fb HW (50 DAS) reported WCE (92.3 %).
