Aim of this research was to study the influence of different levels of sward-podzolic light-loamy soil contamination with Cd on the spring wheat yields, Cd accumulation in grain and straw as well as to find methods of decreasing its entry in the plants. The following regularities were found as a result of the small-plot experiment. On the average in 1997-1998 the yield of spring wheat at the maximum application of cadmium sulphate (9 mg/kg of soil) decreased by 33% compared to the cadmium sulphate-free soil. The content of Cd mobile forms in the soil increased by 18 times, Cd accumulation in grain by 2,2 times and in straw - by 8,3 times
