Although the magnetic field is an indispensible environmental factor for plants in soil, there is dearth of research regarding its effect on plant growth. In order to evaluate the effect of magnetic water on concentration of micronutrient elements in basil leaves, the present experiment was conducted under completely randomized factorial design with two treatments and three replications in greenhouse. The treatments consisted of the kind of water (magnetic and nonmagnetic water) and salinity treatment in three levels (distilled water, 30 mM and 50 mM salinity). The results indicated that the maximum effects on Mn, Zn and Cu concentration in basil leaves were produced by magnetic water. Concerning salinity treatments, the maximum effects on Mn, Zn, Cu and Total Fe in basil leaves were for water with 30 mM salinity. The interaction effects between the kind of water and salinity levels showed that maximum effects on these elements were related to magnetic distilled water.
