Water molecules can be affected by magnetic fields due to their bipolar characteristics. In the present study an experimental maize field was irrigated with magnetically treated water. Tap water was passed through a locally designed alternative magnetic field generating apparatus (110 mT). The maize plants were irrigated by the magnetically treated water from sowing to the seedling stage. Treatment with magnetically treated waterincreased the shoot and root lengths, fresh and dry weight of seedling (30%, 19.1%, 22% and 22%, respectively), compared with the control groups. The contents of photosynthetic pigments, total sugar and total protein of the leaves did not show significant differences between the treated plants and the control group. The ratio of Fv/Fm of seedling and growth parameters of second family were increased, compared to those of non-treated ones. The combined results suggested that the treatment of water a magnetic field with represents a plausible candidate for the mediation of MF effects on plant cells.
