Résumé
Relatively large quantities of water are required for irrigation ; it can utilize waters of a wide range of quality by appropriately management practices. The management of poor-quality waters covers many sectors and there is a need for progress. Furthermore, desert makes 90% of the total area of Egypt. Which limit and reduce the chance of reclaiming and cultivating deserts. Under these conditions, using low quality water for irrigation is mandatory in the present and near future. Therefore, using saline and wastewater in irrigation is gaining importance because of the scarcity of the good quality water. Salt stress generally leads to a reduction in biomass production and nutrient deficiencies. This necessitates looking for an approach to overcome this problem. Among approaches used was magnetized water, which is harmless, healthy and eco-friendly. On the other hand, the availability of fertile soil suitable for crop production in the region is quite limited. Barley is important cereal crop in Egypt. Moreover, Nitrogen (N) is the main component of fertilizer programs necessary for production of high quantity and quality yield of barley. Therefore, dryland barley growers are looking for N fertilizer response information that addresses grain quality and quantity. 15N is one of the most common stable isotopes used in a large scale in studies of soil/plant/fertilizer relationships to monitor N fertilizer application and utilization. This study aims to (i) study the effect of different levels of salinity stress on plant. (ii) Study the effect of the magnetized Water on plant. (iii) Study the transportation of 15N in plant parts. (iv) Study the effect of the magnetized water on N uptake by plant. To reach the research objectives, a pot experiment was conducted in green house at Soil and Water Research Department, Nuclear research Center, Atomic Energy Authority, Abou-Zaabal. The experimental design was split-split plot design with three replicates. Three factors (i.e. magnetized water ; saline water ; nitrogen fertilization with 15N tracer technique) were studied comparing to control treatment.
