Abstract:
Rice (Oryza sativa L.) is considered as the“global grain†and is the staple food for Asia and formore than half of the global population. In India, itcontributes to about 40 percent of the total food grainproduction. Several factors are responsible for reducingthe yield of transplanted rice. However, weed infestationis the major threat to productivity of transplanted riceand causes 45-51% loss in rice yields in India(Veeraputhiran and Bala subramanian, 2013).Transplanted rice in the country encounters diverse typeof weed flora consisting of grasses, broad-leaf weedsand sedges. Weeds, by virtue of their high adaptabilityand faster growth, dominate the crop habitat and reducethe crop yield. Under machine transplanting inter rowspacing of 30 cm allows severe weed infestation inthe field and finally resulting in significant yield loss.Thus, weed management is an essential practice ofmachine transplanted rice and farmers are looking forbetter weed management options in machinetransplanting.
