Abstract

The effects of magnetic water were examined in terms of leaf area, special leaf area, and some of the physiographic indicators such as relative water capacity and foliar chlorophyll content (SPAD) in three species endemic to arid environments namely Nitraria, Haloxylon, and Atriplex. In addition to the factors mentioned, acidity (pH) and electrical conductivity (EC) were also measured. This research was conducted in a completely randomized block design with three replications. Data analysis was carried out via the analysis of variance using MSTAT software. The aim of this study was to investigate the effect of magnetic water on water use efficiency, rehabilitation of land, and the propagation of vegetation cover in arid areas, along with the introduction of a new Water Magnifier Device. The results showed that species irrigated with magnetic water, had better performance in terms of the growth indices. Leaf development was increased by 121.74, leaf area by 108.97 mm2, special leaf area by 3803.74 mm2.gr, RWC by 9.81%, and SPAD by 15.79. Water magnetization process also reduced pH to 5.0 and EC to 3.0 µmhos.cm-1.
