The experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh, from December 2013 to May 2014 to investigate the effect of weeding regime on the performance of aromatic Boro rice (cv. BRRI dhan50). The experiment comprised nine treatments viz. un-weeded, one hand weeding at 20 DAT + pre-emergence herbicide after hand weeding, two hand weeding at 20 and 40 DAT, pre-emergence herbicide followed by one hand weeding at 20 DAT, pre-emergence herbicide followed by one hand weeding at 40 DAT, post-emergence herbicide + one hand weeding at 40 DAT, pre-emergence herbicide + post-emergence herbicide, pre-emergence herbicide + post-emergence herbicide + one hand weeding at 40 DAT and weed free. Panida (pendimethalin) @ 2.5 L ha-1 as pre-emergence herbicide and granite (penoxsulam) @ 93.70 ml ha-1 as post-emergence were used for weed control. The experiment was laid out in a randomized complete block design with four replications. Crop characters, yield contributing characters and yield of aromatic Boro rice significantly influenced by weeding regime.
