SHORT-TERM WATERLOGGING EFFECT ON GROWTH AND YIELD OF MUNGBEAN

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, Dhaka, during April to July 2019 to evaluate the growth and yield attributes of mungbean under waterlogging condition. The experiment comprised of four mungbean varieties, Green Diamond, Crystal, Satin and Celera and two treatments control and waterlogging which was laid out in two factor Randomized Complete Block Design with three replications. The results showed that both the varieties and waterlogging treatment had significant influence on growth and yield traits of mungbean plant. Celera showed the highest (37.04 cm) plant height in both control and waterlogging condition (31.06 cm). Among the four varieties Crystal created the highest SPAD value (50.07 units) than other varieties. After waterlogging, new leaves initiated by Green Diamond in 39 DAS followed by Celera. Number of leaves was higher (11) in Green Diamond in control and it became 4.66 in waterlogging. Celera produced higher pod per plant both in control and waterlogging. The highest yield per plant containing variety was Celera both in control (5.30 g) and (4.19 g) in waterlogging. Whereas the lowest under control in Green Diamond (3.80 g) and under waterlogging in Crystal (1.02 g). The relative yield indicated that Cerela is the most waterlogging tolerant (0.791), followed by Satin (0.563), Green Diamond (0.563) and Crystal (0.196).
