A laboratory experiment was conducted to find out the effect of electromagnetic field on physiological growth and biochemical seedling vigour activities of wheat seed. Seeds of wheat (Triticum aestivum L.) variety UP 2565 were exposed to static magnetic fields of different strength from 100-250 mT at an interval of 50 mT for different duration from 1-4 hour in steps of 1 hour. Exposure to static magnetic field significantly increased shoot length, root length, germination index, germination rate, seedling dry weight, seedling vigour index and dehydrogenase enzyme activity of wheat seed over control seeds, whereas difference in seed germination was non-significant. Seed coat membrane permeability of treated seeds was significantly improved by magnetic field over control seeds. The exposure duration did not significantly influence seed germination, physiological and biochemical seedling vigour parameters of the seeds.
