Abstract

An experiment was conducted at Agricultural Research Station of Bangladesh Agricultural Research Institute (BARI), Pabna during April to August 2001 to see the effect of weed control methods on the growth and yield of rainfed aus rice (CV. BR16). Plant height, effective tillers plant -1, length of panicle, filled grains panicle -1, unfilled grains panicle -1, 1000-grain weight and grain yield were significantly influenced due to different treatments. The maximum number of effective tillers plant -1 (3.60), filled grains panicle -1 (50.54) and grain yield (3.02 t ha -1) were obtained from T5 treatment (Ronstar @ 2.0 L ha -1), which was closely followed by T2 treatment (two hand weeding). The minimum number of effective tillers plant -1 ( 2.30), filled grains panicle -1 (41.32) and grain yield (2.27 t ha -1) were observed in control treatment.
