Abstract:
Rice is an major crop & staple food in India. In Transplanted rice (TPR) consent standing water necessary. For 1kg rice TPR need 500litre of water but now days water scarcity is there. Better altering option for it is Direct Seeded Rice (DSR). But no method is perfect. In DSR less water required, less labour, same amount of yield as TPR possible but major constraint is weed. Because of rice crop & weed establishment at same time lead to more crop-weed competition. It also because of less water use in DSR comparison to TPR. In several studies show that yield loss because of weed in DSR may be up to from 30 to 90% but as comparison to the TPR it is around 10 to 25%. Control of Weeds timely is very important for good yield specially in DSR. First 30 DAS is really important for controlling weed growth. Delay in controlling weed lead to outburst of weed growth. Controlling method depend on availability of resources. If labour available hand weeding or mechanical method. In the sense chemical method more economically viable & effective. But combination of all method in integrated way will give the better result comparison any other single method in direct seeded rice.
