    Abstract


    A pot experiment was set up ingreenhouse conditions at the Faculty of Agronomy, Vietnam National University of Agriculture in the Spring-Summer and Summer seasonof 2018to determine the effects of waterlogging at 3 days after germination, 2-3 leaf, 5-6 leaf and flowering stages on the physiological traitsand individual yield of mungbean cv. ĐXVN5. Each growth stage of mungbean was treated as a separate experiment consisting of 2 treatments:non-waterlogging as control and waterlogging.Waterlogging treatments were maintained at 3 cm-water for one week. The results showed that the waterlogging significantlyreduced plant height, number of leaves, leaf relative water content, root length and root dry matter, chlorophyll content index (SPAD index), dry matter and individual yield of mungbean in bothseasons. Plants at 5-6 leaf stage showed better growth and recovery under waterlogging conditions. The flowering stage was adversely affected by waterlogging stress.
