Abstract
Studies have accumulated over the years to emphasize the importance of the magnetic fields, MF, used as a safe alternative choice to improve agricultural crops. The most important applications of a magnetic field are the treatments of irrigation water, dry seeds, wet seeds and seedlings. The studies also included the application of magnetic fields at different periods of times (minutes, hours and days) and different doses. The effect of different magnetic fields varies depending on the plant species and age during exposure, as well as the intensity of magnetic field and period of exposure. The variation of MF exposure intensities may transform the effect on the plants from a positive to stressful factor. In this review article we highlighted the influence of a magnetic field, and why it is one of the best methods to enhance a plant’s growth and productivity.
