This study included two factors: 1) three irrigation water treatments i) Brackish-water (BW), ii) Magnetic-BW1; brackish water after magnetization through passing a three inch static-magnetic unit produced by Delta Water Company and iii) Magnetic-BW2; brackish water after magnetization through passing a three inch static magnetic unit produced by Magnetic-Technologies Company) and three wheat varieties (Sakha-94, Maser-2 and Gemiza-11). The three irrigation water treatments and the three tested varieties were laid out in split-plot design with three replicates and allocated in the main and sub-plots, respectively under gated pipe irrigations system. The experiments designed at Agricultural Experimental Station of Desert Research Centre, Ras Sidr province, South Sinai Governorate, Egypt. The results indicated that irrigation tested wheat varieties with magnetically treated BW1 or magnetically treated BW2 treatments surpassed irrigation with brackish water in all tested vegetative growth parameters at 75 DAS (i.e., plant height (cm), fresh and dry weight of wheat shoot (kg m 2), water contents (%), Flag leaf area (cm 2 plant-1) as well as shoot contents of N, Mg, Ca, Fe and Cu. While revers trends were recorded in Na, Mn, Zn and proline. Results also, recorded that micromorphological characters as number of cells and thickness of layer in addition to the diameter of vascular bundled especially the xylem vessels were compatible with vegetative growth parameters. The yield crop which is the most important was increased with irrigation by magnetic water. As an average of magnetically BW treatments, the percent of improvement reached to 19.24, 33.97 and 26.99% in grains, straw and biological yield (ton fed-1), respectively compared to irrigation with brackish water. The clear improvement in productivity of tested wheat verities under magnetically treated brackish irrigation water may be due to the reduction of irrigation and/or soil salinity stress as a result of displacement of salts away from the root zone spread, lack of sodium exchange in the soil, availability of most fertilizer elements; increased cations exchange capacity and improved soil aggregation. It be concluded that, application of this technology could be play a vital role for improving wheat productivity when sowing under these conditions.
