Optimal management of water, as one of the main factors of production has an important role in the supply of essential nutrients, increasing yield and reducing leaching. Nowadays, application of magnetic water in many fields including agriculture has been payed attention by many researchers. In order to investigate the effect of magnetic water on plant nutrient uptake, this research was conducted in the controlled environmental conditions in greenhouse of Tarbiat Modares University. Magnetic water was produced using a magnetic device with a magnetic field intensity of 8 to 10 mT. The objective of this study was to investigate the effect of magnetic water on the essential nutrient uptake by bean (Phaseolus vulgaris) in saline conditions. The experimental design was two factors factorial (2x3) arranged in a completely randomized design. The combinations of the treatments were two levels of water; non-magnetic (Normal) and magnetic and three levels of salinity; 800, 1300 and 2100 ppm NaCl, with three replicates. The results showed that with increasing salinity, macronutrient uptake and protein percentage reduced, while micronutrient and sodium uptake increased. Moreover, comparisons of treatments means showed that the magnetic water increased all the nutrients uptake and protein percentage in the leaves and seeds, but no significant changes were observed in the roots and shoots of bean plants. Despite these findings, more researches are needed to be done in the field to prove the obvious beneficial effects of magnetic water.
