Abstract
Weed management is one of the traditional operations in crop production. Due to labour costs, time and fully manual weeding is unfavourable. Competition in the early stage of growth and failure to control weeds in the first three weeks after transplanting, reduce the yield by 50 percent in rice. Manual weeding requires huge labor force and accounts for about 25 percent of the total labor requirement which is usually 900 to 1200 man h/ha. Using mechanical weeders in rice cultivation and other row crops have been common practice in now a day. Cono weeder is one of best tools for weeding in SRI Rice cultivation which compare with hand weeding causes a considerable reduction in labour costs and time consuming.
