The goal of this research is to determine the effects of different levels of water deficit (I 100 : full irrigation, I 65 : 35% deficit, I 40 : 60% deficit and I 0 : no irrigation) on yield and chemical composition of soybean [Glycine max (L.) Merr.] grown in Srem region of Serbia. Water deficit significantly affected the yield and chemical composition of soybean seeds. The lowest (1.63 t/ha) and the highest (3.21 t/ha) seed yields were obtained from I 0 and I 65 treatments, respectively. Furthermore, the highest protein (1092 kg/ha) and oil (563 kg/ha) yields were observed in I 65 treatment. Lower and higher irrigation levels from I 65 decreased the protein and oil yields. Our data indicated that irrigation generally increased K, P, Mg, Mn, Cu, Zn and B concentrations and decreased Ca and Fe concentrations in soybean seed. It was clearly observed that full-watered treatment (I 100 ) provided no potential benefit in terms of soybean yield and chemical composition. For higher economic yield and good nutritional quality, water-saving treatment I 65 could be suitable in soybean management in Srem region of Serbia as in other regions with similar soil and climate conditions.
