Abstract:
The experiment was conducted in the Farm of Sher- e- Bangla Agricultural
University during the period from August to November 2008 to study the growth
and yield response of mungbean varieties under different weed managements. The
experiment consisted of two factors. Factor A: Mungbean variety (2 levels ): V
=
BARI Mung-5 and V
= BARI Mung-6; Factor B: Weed management (7 levels):
W

= No weeding (Control), W
1
= One weeding at 15 days after sowing (DAS), W
=
One weeding at 25 DAS, W
3
= One weeding at 35 DAS, W
= Two weedings at 15
and 35 DAS, W
5
= Two weedings at 25 and 45 DAS and W

= Weed free condition.
The experiment was laid out in a factorial Randomized Complete Block Design
(RCBD) with three replications. Results revealed that, the mungbean variety BARI
Mung-6 stand superior than BARI Mung-5 in respect of plant height (58.45 cm and
56.14 cm), branches plant

(319.24 and 300.20),
seed yield (1.51 t ha

and 2.13 t ha
),
respectively. Among weed management practices, maximum pods / plant (79.32)
seeds/ plant(336.17), seed yield (1.62 t ha
-1
) & straw yield ( 2.53 t ha
) obtained
from weed free which was at par to weeding once & two weedings. In intraction,
the variety BARI Mung-6 weeded twice at 15 & 35 DAS produced maximum yield
(1.75 t ha
-1
) as well as yield attributes. This treatment showed 68.3% higher seed
yield than control.
