| Popis: | Weeds are the major biological constraint in oilseed crops. Yield loss in oilseeds vary from 20 to 77 per cent, depending on the crop, intensity of weed infestation, duration of crop competition, soil and climatic factors. Weed interference, not only reduces the seed yield, but also reduces the oil yield and quality. Critical period of weed control in oilseeds are generally from 15 to 45 DAS. Weed removal during the critical period is essential to reduce the yield loss. Hike in wage rate and phytotoxicity of herbicides calls for an integrated approach for weed management in oilseeds. Instead of relying on a single method, a holistic approach which involves the adoption of cultural/mechanical/biological/chemical methods is essential to keep the weeds below the threshold level for higher yield, productivity and net returns in oilseed crops. |
