This study was carried out at the agronomy farm of Bangladesh Institute of Nuclear Agriculture (BINA), Mymensingh, Bangladesh, between November 2015 and May 2016, to investigate the weed control on rice growth and yield performance of transplant Binadhan-14 (boro rice). Six selected herbicides (H₁: bensulfuron methyl 4% + acetachlor 14% 18 wettable powder [WP] 500 g·ha<SUP>-1</SUP>, H₂: pyrazosulfuron-ethyl 10 WP 125 g·ha<SUP>-1</SUP>, H₃: metsulfuron-methyl 20 water dispersible granule [WDG] 50 g·ha<SUP>-1</SUP>, H₄: pretilachlor 500 emulsifiable concentrate [EC] 1 L·ha<SUP>-1</SUP>, H<SUB>5</SUB>: 2, 4 D amine 480 soluble liquid [SL] 1.8 L·ha<SUP>-1</SUP>, H<SUB>6</SUB>: butachlor 5 granule [G] 25 kg·ha<SUP>-1</SUP>) were tested along with two hand weedings. Weed density, fresh and dry weight of weeds were taken from eight weed species (Echinochloa colonum, Paspalums crobiculatum, Monochoria vaginalis, Leersia hexandra, Scirpus mucronatus, Digitaria sanguinalis, Cyperus rotundus and Eclipta alba Hassk) belonging to five families were found to grow in the experimental plots. Among the weed control treatments highest grain yield (5.00 T·ha<SUP>-1</SUP>) was obtained with the treatment pretilachlor 500 EC 1 L·ha<SUP>-1</SUP> followed by two hand weedings (4.97 T·ha<SUP>-1</SUP>). It was observed that yield was increased due to application of herbicide contributed mainly from increasing the yield contributing characteristics of rice like, number of total tillers and effective tillers per plant, filled grains per panicle and 1000-seed weight (g). Maximum benefit- cost ratio with pretilachlor 500 EC 1 L·ha<SUP>-1</SUP> suggested that this herbicidal treatment can be used for effective in controlling weeds as an alternative when labor was crisis in producing for better yield of transplant Binadhan-14 (Oryza sativa) rice cultivar.
