The use of phosphate fertilizers plays a significant role in cadmium (Cd) accumulation in the soil. In this regards the purpose of our work was to study the effect of Cd on content of mineral elements in the grain of rice varieties. Plants were grown in pots filled with soil, containing 2 mmol/kg of CdSO4. Cadmium was not found in rice grain. The content of mineral elements in grain of rice varieties is decreased in the following order (% of control): Mg-Bakanaskyi (98) > Madina (93) > Chapsari (86%) > Barakat (84); Mn-Bakanaskyi (85) > Chapsari (72) > Madina (71) > Barakat (64); Fe-Madina (89) > Bakanaskyi (72) > Chapsari (57) > Barakat (48); Zn-Madina (93) > Bakanaskyi (87) = Chapsari (87) > Barakat (85); Cu-Chapsari (90) > Bakanaskyi (89) > Madina (83) > Barakat (73). Cadmium decreased the content of necessary mineral elements in rice grain. Content of Mg and Mn decreased in the least degree in Bakanaskyi cv; Fe and Zn content-in Madina variety; Cu content-in Chapsari cv. Under cadmium stress content of mineral elements decreased in the greatest degree in Barakat and Chapsari cvs.
