ABSTRACT
Waterlogging stress is one of the most atrocious environmental factors restricting the
productivity of Mungbean in tropical and subtropical region. So a pot experiment was
conducted at Sher-e-Bangla Agricultural University, Sher-e-Bangla Nagar, Dhaka,
during April, 2019 to July, 2019 to evaluate the growth and yield attributes in
waterlogging condition. The experiment comprised of four Mungbean varieties,
Green Diamond (V
1
), Crystal (V
2
), Satin (V
3
), and Celera (V
) and two treatments
namely control and waterlogging were designated respectively as T
4
. The
experiment was laid out in two factors factorial experiment with Randomized
Complete Block Design (RCBD) and three replications. Pots were placed in the water
chamber after 24 days of germination for 72 hours. The results showed that both the
varieties and waterlogging treatment had significant influence on growth (vegetative)
and yield traits of mungbean plant. It was found that Celera showed the highest
(37.040 cm) plant height in both control and waterlogging condition (31.067 cm).
Among the four varieties Crystal produced the highest SPAD value (50.076 unit) than
other varieties. After waterlogging treatment new leaves initiated in variety named
Green Diamond (V
) in 39 DAS followed by Celera (40 DAS). No. of leaves was
higher (11) in Green Diamond in control and it became 4.666 in waterlogging
treatment. Celera produced higher pod per plant both in control (20) and waterlogging
(12.33). The highest yield per plant containing variety was Celera both in control
(5.3083 g) and (4.1916 g) in waterlogging. So, Celera can be considered as a
waterlogging stress tolerant variety for low laying or flood prone areas of Bangladesh.
