The declining availability of fresh water has become a worldwide problem, which maintains the development of alternative, secondary quality water resources for agricultural use. Several studies recommend that give attention for selected crops that can tolerate a degree of water and salinity stresses when saline water is used for irrigation. In this study, the effects of different irrigation intervals at different salinity levels of irrigation water on Soybean yield and their impacts investigated using three irrigation intervals (I1 =3 days, I2=4 days and I3=5 days) with four salinity levels (S1=4 dSm-1, 5 dSm-1 and 6 dSm-1) in a factorial combination using CRD with three replications. The result showed that salinity, irrigation interval and their interaction were highly significance effects (p<0.001) on number of pod per plant, number of seed per plant and grain yield of Soybean. The highest number of pod number (88.33), grain yield (2.31 ton/ha) and number of seed per plant (172.33) was recorded from Soybean which was irrigated with the first salinity level, i.e., fresh water (S1) with irrigation interval one (3 days), S1I1; while the lowest pod number per plant (6.67), number of seed per plant (12.67) and minimum grin yield (0.034 ton/ha) was obtained from Soybean irrigated by salinity level four (S4) with 5 days irrigation interval (S4I3).
