AbstractA field experiment was carried out to study the impact of irrigation water salinity, water magnetization and soil available moisture depletion percent on some soil physical properties and potato yield and growth during the spring season 2012. The field located at Anbar province latitude 33.2614о N and 43.1755о E longitude with silty loam soil texture classified as Coarse – Loamy; Mixed; active; hyper thermic Typic Torrifluvent.
The experiment includes three factors; the first one was irrigation water salinity with two levels: Euphrates river water with electric conductivity 1 ds. m-1 and drainage water, which was brought from a surface drain, located on the opposite side of the riverbank with Ec 4 ds. m-1, the second factor was two levels of irrigation water magnetization, which were magnetized with 1500 gauss magnetization intensity and without magnetization. The third factor was three levels of soil available moisture depletion percent 50, 60 and 70%s.
Split – split plot with R. C. B. D. experimental design was used with three replicates, Plant height, leaf area and Plant root length were decreased with the increasing of irrigation water salinity and the depletion percent while the same parameters increased when magnetized water used for irrigation.
