This research was carried out under greenhouse conditions in order to examine the effect of cadmium (Cd) application (0, 25, 50, 75, 100, 125 mg kg^-1) on forage quality characteristics in some sorghum (Sorghum bicolor L.) varieties. In this study; Three different sorghum types obtained from BATEM were used as plant material (Akdari, Beydari ve Ogretmenoglu). The study has been completed according to the splite plot experimental design (3 varieties x 1 element x 6 doses x 3 replication). At the end of the growth period (130-day), tannin ratio, crude protein content ratio, oil ratio, ADF (acid detergent fiber), NDF (neutral detergent fiber), DDM (digestible dry matter), DMI (dry matter intake) and RFV (relative feed value) ratios were examined. According to the study, the properties of cadmium were examined in terms of variety x dose interaction; tannin content, oil content, NDF (neutral detergent fiber), DMC (dry matter consumption) and RFV (relative feed value) (P <0.01); protein ratio, ADF (acid detergent fiber), DDM (digestible dry matter) (P<0.05) were statistically significant differences. Grain sorghum varieties were affected by cadmium stress and changes in forage quality characteristics were observed depending on the dose increase.
