This review assesses the impact of waterlogging and submergence on crop physiology and growth of important crops in Bangladesh along with its remedial measures. Waterlogging can take place because of heavy rainfall, inadequate drainage systems, natural flooding etc. Oxygen levels diminish very rapidly in waterlogged root environment. So, damage of crops depends on duration and severity of flooding. The oxygen deficient conditions hamper plant growth, development and survival based on their tolerance to excess water. Under such environment plants exhibit metabolic switch from aerobic respiration to anaerobic fermentation, resulting in reduced rate of energy production by 65-97%. Anaerobic roots may also die from self-poisoning byproducts of anaerobic metabolism. The flooding also impedes the diffusive escape and/or oxidative breakdown of gases such as ethylene or carbon dioxide resulting in its accumulations. The accumulated ethylene may slow root extension, while carbon dioxide can severely damage roots of certain species. Moreover, waterlogged plants often face the oxidative damage induced by the generation of reactive oxygen species. However, all the plants have the ability to detoxify the adverse effects of reactive oxygen species (ROS) by producing different types of antioxidants such as ascorbate peroxidase (APX), superoxide dismutase (SOD), peroxidase (POD), catalase (CAT), glutathione reductase (GR), ascorbic acid, glutathione, tocopherols and carotenoids. Prolonged exposure of plants to flooding conditions could result in root injuries which in turn restrict photosynthetic capacity by inducing certain alterations in biochemical reactions of photosynthesis. Waterlogging is also known to induce adverse effects on several physiological and biochemical processes of plants by creating deficiency of essential nutrients like nitrogen, magnesium, potassium, calcium. Species with inherently surface-inhabiting root systems are notably tolerant of prolonged waterlogging. There are several options for mitigation of submergence and waterlogging problems like breeding of waterlogging tolerant varieties, improvement of drainage systems and changing in crop husbandry. Providing adequate drainage, foliar spraying of fertilizers and hormones can alleviate waterlogging problems. Bed planting in waterlogged prone areas and floating beds in flooded areas are good options for high value crops.
