N2  - A field study was carried out in Tegzerty region, at Siwa Oasis, Egypt, which located at 29° 10'53" N and 25° 33' 12" E. The experiment was done for two successive seasons 2013-2014. Flax (Unum usitatissimum L.) c. v Sakha3 was the test plant. The aim of this study was to evaluate the effect of fertilization under the conditions of saline water irrigation and high water table in loamy sand soil at Siwa Oasis using the mineral and bio-fertilizers of P and foliar Zn applied during different growth stages of flax plants under different rates of water stress. Yield parameters of flax plants, nutrients content and uptake in seeds increased with increasing of the P, Zn and moisture content rates additions during the two studied seasons. Application of Azotobactor chroococcum (AZ), Pseudomonas fluorescens (SD) and Bacillus megatherium (PDB) increased yield parameters, nutrients content and uptake. Combining mineral P with biofertilizers increased yields as following; P+(AZ)<P+(AZ)+ (SD)<P+(AZ)+(PDB)<P+(AZ)+(SD)+(PDB). The most effective treatment was P2+ (AZ)+ (SD)+(PDB)+ Zn1 under conditions of the irrigation of every 10 days which gave 2.34, 11.1. 0.99 and 1.82 for weight straw, seeds, oil and fiber (Mg ha-1 ) respectively in the-..first season, while in the second season it achieved 2.48, 11.4, 1.09 and 1.89 (Mg ha-1 ). Fo/iat application of Zn 1 increased yield components, oil content and seed nutrients content and uptake. Irrigation interval every 10 days increased yield components, nutrients content and uptake by seeds of flax plants than the irrigation interval every 20 days
