Toxic effect of heavy metals (Cd, Cu, Ni, Pb and Zn) jointly applied into the soil as a single dose (Me-1) and triple dose (Me-3) on 19 cultivated plant species were compared under pot experiment conditions. A measure of toxic activity of the metals was a decrease in the plant yield as compared to the control object — without their addition to soil. Perennial ryegrass, wheat, oats, maize and hemp proved totally resistant to the applied metals. Buckwheat, sunflower, rape, oil radish, lettuce and beans were little sensitive, whereas phacelia, radish and onion were medium sensitive. In case of serradella, clover as well as spinach, parsley and red beets even a small dose of the metals applied to soil visibly inhibited their growth. Limiting of the above ground plant parts growth as a result of the heavy metals application occured simultaneously with a depression in the yield of their roots.
