ABSTRACT
Rice-the major crop of Asia is typically grown by the transplantation of seedlings in prepared land which demands increased manual power and large water quantity. Nowadays, many farmers are therefore moving toward the direct-seeded rice systems that are of two types-wet-and dry-seeded rice. The direct-seeded rice system offers numerous benefits to farmers but major limitation is the growth of weeds due to the absence of standing water and rice seedlings, thus causing a significant loss in rice yield. However, weeds can be controlled by application of herbicides or manually. Manual weeding is today less prevalent due to the increased labor cost and unavailability of labor. On the other side, increased use of herbicides may lead to shifts in weed populations, development of resistance in weeds, and pollution. Therefore a strong need is nowadays felt to integrate the weed management practices for controlling the weeds in direct-seeded rice systems. This chapter deals with the introduction of commonly found weeds, and traditional and recent weed management practices in directseeded rice systems.
