| Abstract | ||||
| In this study, Atriplex seedlings were cultivated during the 2021–2022 and 2022–2023 seasons at the Faculty of Agriculture, Mansoura University, Egypt in order to evaluate effects of saline irrigation water on plant performance at different concentrations of diluted seawater. The irrigation treatments included: 100% Nile water (control), 25% saline water, 50% saline water, 25% magnetized saline water, and 50% magnetized saline water. Seawater was used as a source of saline water and was diluted with Nile water. Thereafter, magnetization process was carried out using a magnetic water treatment device. Results showed that magnetized saline water (MSW) resulted in a decrease in water pH and the water salinity which has a positive impact on soil, water and plant properties, where decrease in soil salinity was observed by 8.63% and 10.22% using 25% and 50% magnetized saline water, while enhanced soil nutrients availability and plant content of macro and micronutrients (e.g. N, P, Cu, Zn, and Mn). Irrigation with magnetized saline water effectively reduced soil concentrations of available Na, Cl and ESP. Moreover, Atriplex plants tolerated up to 50% magnetized saline water with no significant negative impact on vegetative growth, fresh and dry weight, chlorophyll and proline content compared to the control treatment. Additionally, 25% and 50% magnetized saline water achieved higher drought resistance indices (DRI) than their non-magnetized counterparts in both seasons. Also, These treatments demonstrated high potential to save about 25–50% of the total irrigation water required for Atriplex cultivation during various growth stages. | ||||
