This research examines how zinc (Zn) treatments minimize the destructive effects of cadmium (Cd) pollution in soybean (Glycine max L. cv. Palam Soya) and chickpea (Cicer arietinum L. cv. GPF-2). Plants received controlled sand culture nutrition which included different Cd concentrations (0.1, 0.3, 0.6 mM) and Zn concentrations (0.1, 0.3, 0.8 mM). The study showed that Cd stress damaged plant growth and chlorophyll development and yield characteristics along with downstream effects that were more pronounced in soybean growth than in chickpea. Zinc supplementation proved efficient in countering Cd negative impacts by improving water consumption and enhanced antioxidant capabilities as well as biomass productivity when used at elevated doses. The research documented how chickpea and soybean exhibit different reactions to metals together with antioxidants and seed yields while revealing that zinc minimizes seed Cd accumulation. The research findings reveal crucial physiological as well as biochemical strategies which enhance crop resistance in Cd-contaminated soils.
