Heavy metal like lead and chromium present in environment in large quantities cause a severe environmental concern. Significant risks to the environment and agriculture are posed by heavy metal contamination of the air, water, and soil as a result of increased urbanization and industrialization. Because of its permanence and high toxicity, heavy metal contamination in soils can have a negative impact on neighboring ecosystems, groundwater, agricultural production, and human health. Plants growing in metal-contaminated soil collect heavy metals in their tissues, which may negatively affect the morphology of the plant. The present study was carried out to determine the effect of different concentrations (50 ml, 100 ml, 150 ml and 200 ml) of chromium and lead on morphological attributes of three varieties (JS:335), (JS:80-21), (JS:75-46) of soybean (Glycine max). According to the results of the present research, Glycine max plants' overall length, number of nodes, and number of leaves decreased after being exposed to Pb and Cr. With increasing concentrations of heavy metals, the form of the leaves of treated plants significantly altered from ovoid to heart and oval shapes. Among the three different varieties (JS:335), (JS:80-21), (JS:75-46) of Glycine max (soybean) JS:335 showed extreme reduction and the JS:80-21 showed least reduction in the growth of a plant. Lead treatment proved more toxic than chromium treatment for all the three different varieties (JS:335), (JS:80-21), (JS:75-46) of Glycine max.
