Abstract:
The experiment was conducted during the period from March to June 2013 at the
farm of Sher-e-Bangla Agricultural University, Sher-e-Bangla Nagar, Dhaka,
Bangladesh to study the effect of variety and flower removal at 3 intervals out of
the cropping duration of mungbean. The varieties like BARI mung-3, BARI
mung-4, BARI mung-5 and BARI mung-6 were used as the test crop. The
experiment consists of two factors designated: Factor A (Mungbean variety 4; V
:
BARI mung-3, V

: BARI mung-4, V

: BARI mung-5 & V
: BARI mung-6) and
Factor B (Flower removal 4 levels; R

: No removal of flower, R
: Removal of
flower at 30-35 DAE, R
2
: Removal of flower at 40-45 DAE & R
: Removal of
flower at 50-55 DAE). The experiment was laid out in Randomized Complete
Block Design (RCBD) with three replications. The tallest plant (54.05 cm) was
recorded from V

, whereas the shortest plant (44.13 cm) was recorded from V
.
The maximum number of pods per plant (19.98) was recorded from V
, whereas
the minimum number of pods per plant (18.16) was recorded from V
. The
highest seed yield (1.99 t/ha) was recorded from V
, whereas the lowest seed yield
(1.63 t/ha) was observed from V
