Abstract: The objective of this study was to investigate the effect of different waterlogging regimes on growth, yield and roots development in three fiber crops. Three fiber crops kenaf (Hibiscus cannabinus L.), roselle (Hibiscus sabdariffa L.) and jute (Corchorus olitorius L.) were subjected to waterlogging for 45, 60, 75, 90 and 105 days, as well as a well-drained subject (control). The waterlogging regimes had a significant effect on plant height, stem diameter, leaf area, biomass production, root growth and aerenchyma tissue formation. The crops subjected to waterlogging for longer periods were more affected in their growth characteristics: H. cannabinus had a higher plant height, stem diameter, leaf area, biomass production and root growth less than H. sabdariffa and C. olitorius. Aerenchyma tissue developed in adventitious roots of three fiber crops species. The fiber crops subjected to waterlogging regimes decreased fiber yield by 11.9-51.2% compared to the control. H. cannabinus produced the highest fiber yield after 45 days of waterlogging duration. This results is due to the higher growth and roots development of H. cannabinus than the other two fiber crops.
