Cadmium is one of the most toxic heavy metal in the environment. Cadmium presence in soil can cause serious problem to all organisms through food chain. The present study was conducted through pot culture experiment to estimate the effect of cadmium (10, 25, 50, 75, 100, & 200mg kg-1 soil) on the morphological parameters (root length, shoot length, number of leaves, total leaf area, fresh and dry weight of root, stem, leaf) of tobacco. The values were recorded on 30th, 60th, 90th, 120th, 150th and 180th days of tobacco. For all the morphological parameters, the highest values were recorded in control. Due to increase in cadmium concentrations all the morphological parameters were decreased from 10mg kg-1 to 200mg kg-1 of soil.
