Chhattisgarh state is considered as one of the centers of origin and evolution of rice and is blessed with enormous funds of rice variability. Scented rice constitutes a special group of rice and the cultivation of scented rice varieties is one of the oldest practices. Looking to the changing consumer preferences, the demand of the scented rice is increasing day by day. The availability of scented rice in comparison to the demand is meager due to low productivity and susceptibility to several biotic and abiotic stresses. Weed is one of the important factor caused reduction in the productivity of scented rice. In this perspective the present study was undertaken in Jashpur district of Chhattisgarh with data collected from 144 scented rice growing farmers. The findings shows that, majority of the respondents perceived that wild rice (Oryza nivara), Sarbana/Samna (Echinochloa spp.), Motha (Cyperus spp.), Kankauwa (Commelina bengalensis), Bhorandi/Badauri (Ischaemum rugosum), Machhli ankh (Panicum repens) and Masariya (Corchorus spp.), in order are the major weeds causing yield loss in scented rice varieties. Accordingly it was found that the severity of Echinochloa spp. was highest. The yield loss caused due to these weeds is up to 75 per cent. Remarkably, it was found that almost all farmers follows the traditional weed management practices and only few scented rice growers were using chemicals for the management of weeds. It shows a complex situation which has to be overcome by incorporating strategic extension approaches so that the effective weed management can be done in scented rice cultivation to increase the productivity and profitability.
