GROWTH AND YIELD OF MACHINE TRANSPLANTED RICE AS INFLUENCED BY WEED MANAGEMENT PRACTICES

Rice (Oryza sativa L.) is considered as theÂ â€œglobal grainâ€ and is the staple food for Asia and forÂ more than half of the global population. In India, it
contributes to about 40 percent of the total food grainÂ production. Several factors are responsible for reducingÂ the yield of transplanted rice. However, weed infestation is the major threat to productivity of transplanted riceÂ and causes 45-51% loss in rice yields in India
(Veeraputhiran and Bala subramanian, 2013).Â Transplanted rice in the country encounters diverse typeÂ of weed flora consisting of grasses, broad-leaf weedsÂ and sedges. Weeds, by virtue of their high adaptability
and faster growth, dominate the crop habitat and reduceÂ the crop yield. Under machine transplanting inter rowÂ spacing of 30 cm allows severe weed infestation inÂ the field and finally resulting in significant yield loss.
Thus, weed management is an essential practice ofÂ machine transplanted rice and farmers are looking forÂ better weed management options in machineÂ transplanting.
