| Abstract | ||
| Two field experiments were conducted at Sakha Agric. Research Station, during two successive seasons 2013 and 2014, to study the effect of the magnetized water treatment (MWT) on some soil proprieties and productivity of soybean under salt affected soils conditions. A split plot design with three replicates was used . The main plots were occupied by water types (fresh water and magnetic irrigation water) and sub plots were devoted to water quality: 0.75dSm-1 (S1) , 1.75 dSm-1 (S2) and 2.75 dSm-1 (S3). The obtained results could be summarized as follows: - The growth parameters of soybean plants were high significantly increased due to application of the magnetic water. - The soybean seed, straw and yield components were high significantly increased by magnetic water application under different water salinity. -Protein and oil yields were high significantly increased by magnetized water treatment (MWT), while they were decreased with increasing of irrigation water salinity. - The magnetic treatment of irrigation water had a positive effect on decreasing salinity of the soil (ECe) after the harvest of plants. Values of relative change (Rc± %) of soil salinity (Ece) , sodium adsorption ratio (SAR), Na+, Cl- and SO2-4 were decreased while (Rc± %) of Ca++, Mg++, and K+ in the soil extraction , after harvesting, were increased due to MWT under S1; S2 and S3, as compared with magnetized fresh water . -Yield of soybean , yield components, protein and oil yield content were positively correlated with (MWT) during both seasons. -It could be concluded that to alleviate water salinity hazard, improve some soil properties and increase productivity of soybean plant can be obtained by magnetic water treatment under salt affected soil. | ||
