This study aimed to determine the effect of different irrigation water salinity levels on two different sweet sorghum (Sorghum bicolor L.) variety (Erdurmuş and Uzun) growth, evapotranspiration, some growth parameters, and ion uptake in leaves and roots. Six different saline irrigation water levels (S0=0.5 (control), S1= 1.0, S2: 2.0, S4=4.0, S8= 8.0, and S16=16.0 ds m-1) were obtained by mixing the NaCl and CaCl2 salt species into the tap water source. Plants were harvested before the phase of florescence. Increasing salinity level first increased and then decreased all growth parameters (Stem length, root length, fresh stem weight, fresh root weight, dry stem weight, and dry root weight). The increased salinity level after S2 treatment resulted in decreased water use efficiency. The salinity level affected the uptake of all ions in the root (except the Kion) and leaf, and as the salinity level increased, the amount of N, P, Mn, Znand Na in the leaf increased significantly, while the amount of K, Ca, Mg, Fe and Cu decreased.
