GROWTH AND YIELD PERFORMANCE OF MUNGBEAN VARIETIES UNDER WATERLOGGING CONDITION

Abstract

The experiment was conducted in the research field of Sher-e-Bangla Agricultural University, Dhaka during the period from March 2022 to June 2022 to find out the growth and yield performance of mungbean varieties under waterlogging condition. The experiment comprised of two factors; Factor A: V 1 = BARI mung-6, V = BARI mung-7 and V 3 = BARI mung-8; and Factor B: W 0 = Control (no irrigation), W 2 = Well watered (under normal condition) and W = Waterlogged condition (at pre-flowering stage 24 hours at 20-30 DAS). The experiment was laid out in a Randomized Complete Block Design (RCBD) with three replications. Data were recorded and significant variation was observed for most of the characters studied. Mungbean varieties and waterlogging condition had significantly influenced by growth and yield characters. In case of combined effect of variety and different waterlogging condition, significant variation was observed on the growth and yield of mungbean. Results indicated that the tallest plant (56.75 cm at 60 DAS), the maximum leaves plant 2 -1 (15.67 at 60 DAS), branches plant -1 (4.27 at 60 DAS), pods plant -1 (25.25), seeds pod -1 (12.80), pod length (13.21 cm), 1000-seed weight (51.85 g), seed yield (1.82 t ha -1 1 ), stover yield (3.21 t ha ), biological yield (5.03 t ha -1 ), harvest index (36.15%), available phosphorus content (22.75 ppm) and exchangeable potassium content (18.33 meq 100 g soil) in post harvest soil was obtained from V 2 W (BARI mung-7 growing at well watered condition) treatment combination. On the other hand, the shortest plant (50.00 cm at 60 DAS), minimum leaves plant -1 1 (10.75 at 60 DAS), branches plant -1 (3.00 at 60 DAS), pods plant -1 (15.75), seeds pod -1 (9.15), pod length (9.13 cm), 1000-seed weight (40.23 g), seed yield (1.34 t ha -1 ), stover yield (2.72 t ha -1 -1 ), biological yield (4.06 t ha ), harvest index (33.00%), available phosphorus content (17.82 ppm) and exchangeable potassium content (13.33 meq 100 g -1 soil) in post harvest soil was recorded from V

(BARI mung-8 growing at waterlogged condition at pre-flowering stage 24 hours at 2030

DAS) treatment combination. So, BARI mung-7 variety can be grown at well watered condition for obtaining higher yield of mungbean.
