The impact of some heavy metals (Zn, Cu, Mn) by accumulation activity of seeds maize through migration way water-soil-plat was studied. Comparison of kinetic covers of the maize growth cultivated in open field and in the laboratory chamber with controlled condition allows us to note that the Armenian corn was investigated in natural conditions, and the inbred line B73 was investigated in laboratory with a maximum close to natural. As the plant grows in the field, changes are observed in the physiological parameters of growth, which are close in terms of indicators for a severe drought in the laboratory. The concentration of Zn, Cu and Mn in the triad of water-soil-plant during the maturation of the plant, which was grown on semi-desert brown soil and was irrigated with artesian water of the Araks River basin, was determined. The concentration changes some of heavy metals in corn grains may be caused by an increased content of the latter in the soil as a result of the use of contaminated irrigation water. The obvious migration of pollutant metals along the water-soil-plant chain is a serious threat to the environment and biota, for food safety.
