Abstract	Soybean (Glycine max L.) is one of the main crops and is widely cultivated in the world. Egypt has a semi-arid country with limited fresh water resources. In order to supply to irrigation water demand, it needs to use of non-conventional water resources such as saline or brackish water for irrigation. With this in mind, an pot experiments was conducted at plant nutritional physiology laboratory, Hiroshima University, Japan in 2010 to investigate the effect of irrigation with saline water on three Egyptian soybean cultivars (Giza-35, Giza-82, and Giza-111) under a non-saline (control) and saline (10 mM NaCl) conditions. The effects of salinity on crop was studied by measuring plant growth parameters. The water relations were estimated by studying the relative water contents and electrolyte leakage. The response to salinity stress was analysed by estimating the chlorophyll content, nitrogen, K, Na, proline content of plant tissue. The results showed a negative relationship between salinity stress and most of the measured plant growth parameters. In contrast, proline, Na and electrolyte leakage increased with irrigation water salinity. Results indicated that Giza-111 cultivar surpassed other cultivars in all characters under study. The highest value of crop dry weight, relative water content and accumulation of N, K and proline observed in Giza-111 with the compare to another cultivars. On the other hand, electrolyte leakage and Na ions accumulations were increased in the shoot under salinity in all cultivars. However, the lowest accumulation of Na ions was occured in Giza-111. Similarly, Giza-111 was more stabilited membrane to leakage. As a result, Giza-111 cultivar showed more capability and appropriate to survive under salinity condition compared with another cultivars regarding of almost all plant traits.
