Impact of varying water-logging durations at various stages of growth on mustard seed yield

Waterlogging significantly affects agricultural growth and development, making it a severe constraint limiting crop production and quality. This study aims to assess the level of water tolerance of standard mustard cultivars while taking into account the influence of varied water-logging durations on mustard seed output. In this study, a randomized complete block design was used to examine the effects of water-logging on the various phases of various mustard varieties under ambient temperature and sunshine circumstances. Binasarisha-9, Binasarisha-11 and BARI Sarisha-14 were the varieties utilized in the experiment, and water-logging treatments were applied at different times of 0, 24, 48, and 72 hours at 55–60 days after sowing (DAS). Data on plant height, branches plant-1, and siliquae plant-1 were taken from 10 randomly selected plants from each plot. The maturity period was counted when 90% of siliquae matured. The seed yield of each plot was recorded after harvest. The result shows that the highest seed yield (1.51t ha-1) was found for Binasarisha-11 under water-logging conditions for 24 hours at 55-60 DAS and almost the same result on seed yield (1.46t ha-1) for Binasarisha-9 was found for the same treatment. Moderate yield at 48 hours water logging was observed whereas there was significant yield reduction for 72 hours water logging. BARI Sarisha-14, Binasarisha-9, and Binasarisha-11 yielded 4.5%, 1.38%, and 11.56% less than non-water-logged situations after 72 hours of water-logging at 55-60 DAS. However, it could be concluded that these results provide valuable insights into the effects of waterlogging on seed yield and can aid in selecting suitable mustard genotypes in flood-prone environments to mitigate the negative effects of climate change.
