Root System Architecture and Symbiotic Parameters of Summer Mung Bean (Vigna Radiata) under Different Conservation Agriculture Practices

Root system architecture plays a vital role in plant growth, development, and adaptation by absorbing water nutrients providing mechanical support for growing plants. Unfortunately, little information is available the literature on root dynamics of summer mung bean under conservation agriculture conditions. In this study, field experiments were conducted during seasons two consecutive years (2020 2021) to investigate different practices. The highest stem width, depth width length, number nodal roots, taproot diameter, secondary length (both right left) recorded Soybean (permanent bed; PB)-Wheat(PB)-Summer (PB)(+Residual; +R) based cropping systems, followed Maize(PB)-Wheat(PB)-Summer (PB)(+R), while, lowest values above parameters Puddled Transplanted Rice–Conventional till (PTR-CT)Wheat-Summer (-R). Further, pod seeds per pod, pods plant, seed yield symbiotic (including nodules leghaemoglobin content) dry weight (PB)-Wheat (PB)-Summer (PB)(+R). Interestingly, increased around 13.4–29.5% when residues retained soil surface with treatments involving residual removal. dehydrogenase enzyme activity significantly (PB)(+R) as compared PTR-CT Wheat-Summer addition, exhibited positive correlation both crop seasons. Overall, study suggests that inclusion soybean-based systems may substantially improve quality increase agriculture.
