Effect of agronomical manipulations were evaluated in Instructional cum Research Farm, S. G. College of Agriculture and Research Station, Kumhrawand, Jagdalpur, Chhattisgarh, India under RCBD (Randomized Complete Block Design) with four replications in transplanted rice (var. MTU-1001) during kharif season 2018. Result revealed that hand weeding twice @ 20 and 40 days after transplanting provide wide spectrum weed control than remaining treatments except bispyribac-sodium @ 80 g /ha at 15 DAT which was at par to that of hand weeding twice. The dry matter of grasses, sedges and broad leaved weeds in weedy check plot had higher than other treatments during the course of observation. The crop growth parameters (tillers, leaf area index) and yield attributes (panicle length, grain/panicle, panicle weight) and grain yield were recorded highest in hand weeding twice at 20 and 40 day after transplanting (4.27 t/ ha) than rest of treatments except application of bispyribac- sodium @ 80 g/ ha at 15 days after transplanting (4.03 t/ ha) which were 40.94% and 32.77% increased in yield over control. The result suggested that hand weeding is most effective methods for weed management in transplanted rice and the bispyribac sodium @80 g/ha was the best broad spectrum herbicide in order to minimize the diverse weed flora in transplanted rice.
