A field trial was conducted during kharif season of 2017-18 and 2018-19 in red sandy clay loam soils of Agricultural Research Station, Ragolu. The trial was taken up with ten organic weed management treatments in randomized block design in three replications. From the data analysed for two years it was concluded that weeds can be managed in organic rice by Summer ploughing followed by Green manuring followed by 3 weeks puddling interval + One conoweeding at 15 DAT +Need based hand weeding at 40 DAT as it has recorded the highest mean grain yield (6542 kg/ha), WCE (77.77%) and B:C ratio(1.50) as compared to other treatments and hence can be recommended for organic rice production
