The effect of magnetic field on the germination of Zea mays seeds has been studied in the present work. Seeds were magnetically exposed to static magnetic field strength of 50mT for different time of exposure, 0.25, 0.5, 1 h, respectively. The goal, is to observe biochemical changes and stimulation effect on the germination of Zea mays plants. The effect of the exposure rate on the root growth, radicle length and protein percentages were discussed and statistic significance analysis was assessed for the differences between the average values of samples and controls. It is found that variable magnetic field exposure time rate (100 mT/hr) is a very significant factor in influencing the germination process of seeds Zea mays in compared with non treated seeds. It is observed, that the root length, radicle length and protein percentage increased by 31.14%, 4.15% and 11.32% respectively.
