Calcium application lowers the accumulation of heavy metal cadmium in chickpea and mungbean.

Chickpea (Cicer arietinum L. cv. Himachali channa II) and mungbean (Vigna radiata L. Wilczek cv. Mung 666) genotypes were subjected to varying levels of heavy metal stress to assess their tolerance levels towards cadmium induced heavy metal toxicity, its uptake behavior and accumulation in the leaves and seeds. Mungbean cultivar had shown better tolerance towards the heavy metal depicted in terms of better growth profile, relative leaf water content, electrolyte leakage, leaf pigments, yield attributes of the crop comprising flower, pod and seeds in comparison to chickpea. Mungbean leaves acted as hyper-accumulators of the metal with minimal translocations directed towards the seeds. Higher leaf surface area of the mungbean crop accompanied by more watery requirement during summer season was the possible reason for such accumulation. On the other hand, in chickpea, a winter seasoned crop cadmium accumulation was many times in the seeds in comparison to mungbean depending upon toxicity level of heavy metal. Calcium application played an important role in lowering the accumulation of cadmium in both leaves and seeds with improved water absorption at the root surface and its further uptake. Cadmium toxicity can be checked effectively with the application of calcium in the rhizosphere.
