Abstract
The experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh during November 2016 to May 2017 to study the effect of weed management strategies on the yield of aromatic fine rice in Boro season. The experiment comprised three aromatic fine rice varieties viz. BRRI dhan50, BRRI dhan63 and Basmati, and five weed management strategies viz. weedy check (no weeding), two hand weeding at 15 and 30 days after transplanting (DAT), pre-emergence herbicide, Panida 33 EC @ 2.5 l ha-1 + one hand weeding at 30 DAT, post emergence herbicide, Granite 240 SC @ 95 ml ha-1 + one hand weeding at 30 DAT, pre-emergence herbicide, Panida 33 EC @ 2.5 l ha-1 + post emergence herbicide, Granite 240 SC @ 95 ml ha-1. The experiment was laid out in a randomized complete block design with three replications. BRRI dhan50 produced the highest number of effective tillers hill-1 (8.87), number of grains panicle-1 (95.51 grain) and 1000-grain weight (21.45 g) and straw (5.59 t ha-1) yields compared to BRRI dhan63 and Basmati. The highest grain yield (4.31 t ha-1) was produced in BRRI dhan50 which was at par with BRRI dhan63 and the lowest one (3.21 t ha-1) was recoded in Basmati. In case of weed management, the highest number of effective tillers hill-1 (9.62), 1000-grain weight (21.70 g), grain (5.22 t ha-1) and straw (5.64 t ha-1) yields were obtained in pre-emergence herbicide + post emergence herbicide compared to other treatments. In interaction, the highest grain yield (5.54 t ha-1) was obtained in BRRI dhan50 with pre-emergence herbicide + post emergence herbicide, which was statistically identical to BRRI dhan63 with pre-emergence herbicide + post emergence herbicide. Therefore, BRRI dhan50 or BRRI dhan63 can be cultivated with pre-emergence herbicide + post emergence herbicide in Boro season for appreciable grain yields.
