In this current period of time, environmental heavy metal contamination is an increasing concern that affects all life forms. Among the issues concerning the heavy metals, cadmium is a toxic, silver-white metal element that can be readily absorbed by plants, enters the food chain, and poses a major health risk to humans. When crops are grown in regions where heavy metal levels are above threshold levels they become an integral part of the food chain. Pigeon pea is one among the major cultivated edible legume crops of India with incredible medicinal and nutritional values. Thus, it is very imperative to determine the effect cadmium on plant growth and physiochemical of pigeon pea. Hence, a pot experiment was carried out to study the effect of 25 µM/L, 50 µM/L, 75 µM/L and 100 µM/L CdCl2 concentration on growth and physiology of pigeon pea and it showed that the CdCl2 induced remarkable decrease in root length, shoot length, chlorophyll and carotenoids levels, carbohydrate and proteins contents of the test plant. This can be attributed to the nutritional deficiency, reduced photosynthetic activities and enhanced reactive oxygen species production in response to cadmium stress. Finally, this manuscript may help to determine the essential remediation strategies to overcome the contamination of edible legume crops with Cd in agricultural soils in order to reduce the it’s entry into human body through the food chain, that causes chronic poisoning and endangering human health by their consumption.
