Impacts of Water Logging on Soil Microbial Intentions and Mung Bean (Vigna radiata L.) Physiology

Abstract

The mung bean (Vigna radiata L.) is an important pulse crop known for its high protein content and adaptability to tropical and subtropical regions, particularly in Asia. Despite of their importance as a source of protein, most noticeably that, waterlogging negatively affects their growth and yield. Waterlogging, resulting from factors like compacted soil and excessive irrigation, leads to hypoxic conditions and negatively affects various physiological and morphological aspects of mung bean plants. The impact of waterlogging on mung beans at different growth stages emphasises its detrimental effects on root growth, leaf area, chlorophyll content, photosynthesis, and biomass. Waterlogging disrupts nutrient uptake, causing deficiencies and hindering overall plant adaptation. The molecular responses and metabolic changes in mung beans under waterlogging stress can upset the shift to anaerobic metabolism and the synthesis of specific proteins. Microbial interactions in the rhizosphere soil and their influence on mung bean growth during waterlogging also play an important role in mung bean growth and yield. Tolerance mechanisms, including morphological adaptations and physiological changes, are explored, offering insights into selecting tolerant genotypes. Agronomic strategies, such as the use of cytokinin and gibberellin acid used for mitigating waterlogging effects and enhancing mung bean resilience.
