Abstract
In this study, the biological effects of magnetically treated water (MTW) under different water regimes (70, 50, and 30% SWHC) on water relations, photosynthetic pigments and nutrient contents of Jojoba plants has been studied under laboratory conditions. The results indicate that the magnetically treated water especially at 50 and 30% treatments has an enhancing effect on the photosynthetic pigments compared to the control. Also water use efficiency (WUE) (in term of biomass produced to amount of water consumed), was increased in the plants irrigated with MTW as compared to the control treatment, while relative water content (RWC) was increased with MTW under 30% soil water holding capacity (SWHC) to the highest levels only after both 6 and 8 months. The essential elements except sodium were increased significantly (P≤0.01) in plants irrigated with MTW compared to their control. Thus, the present results have shown that irrigation with MTW can be considered as one of the most valuable modern technologies that can assist in saving irrigation water and reducing salt accumulation in plants.
Key words: Jojoba, magnetic water treatment (MTW), water use efficiency (WUE), relative water content (RWC)
