This experiment was conducted to find the most suitable crop establishment method and weed management practices for transplanted aman rice in Bangladesh. Rice variety Bangladesh Rice Research Institute (BRRI) dhan44 was used as planting materials where three crop establishment methods (T1: direct wet seeding by drum seeder; T2: hand broadcasting; T3: transplanting) and four weeding options (W1: Hand weeding (HW); W2: BRRI weeder+HW; W3: Herbicide+HW; and W4: no weeding) were tested. Among the crop establishment methods, the highest grain yield (5.12 t ha-1) was obtained with the T3, while the highest benefit cost ratio (BCR) of 2.08 was found in T2. In case of the weed management method, W1 showed superior results on the plant density/m2 (139.66) at 60 days after transplanting (DAT), grain yield (4.97 t ha-1), and BCR (2.03). On the other hand, the highest plant dry matter (36.20 g) at 60 DAT and the highest yield (6.10 t ha-1) were obtained in a T3W1 combination. The results of this study show that the productivity of rice during aman season could be most significantly increased with the use of transplanting (T3) alone, hand weeding (W1) alone, or a combination of the two methods (T3W1).

This experiment was conducted to find the most suitable crop establishment method and weed management practices for transplanted aman rice in Bangladesh. Rice variety Bangladesh Rice Research Institute (BRRI) dhan44 was used as planting materials where three crop establishment methods ($T_1$: direct wet seeding by drum seeder; $T_2$: hand broadcasting; $T_3$: transplanting) and four weeding options ($W_1$: Hand weeding (HW); $W_2$: BRRI weeder+HW; $W_3$: Herbicide+HW; and $W_4$: no weeding) were tested. Among the crop establishment methods, the highest grain yield ($5.12t\;ha^{-1}$) was obtained with the $T_3$, while the highest benefit cost ratio (BCR) of 2.08 was found in $T_2$. In case of the weed management method, $W_1$ showed superior results on the plant $density/m^2$ (139.66) at 60 days after transplanting (DAT), grain yield ($4.97t\;ha^{-1}$), and BCR (2.03). On the other hand, the highest plant dry matter (36.20 g) at 60 DAT and the highest yield ($6.10t\;ha^{-1}$) were obtained in a $T_3W_1$ combination. The results of this study show that the productivity of rice during aman season could be most significantly increased with the use of transplanting ($T_3$) alone, hand weeding ($W_1$) alone, or a combination of the two methods ($T_3W_1$).
