Design, Fabrication and Evaluation of a Novel System for Magnetic Field Application to the Seeds- Case study of Onion Seed

Non-chemical treatments are an approach for improving seed germination. In order to evaluate the effects of the magnetic field application on onion seed germination and seedling growth indices, a quadrupole magnetic field system was designed and fabricated. It was also compared with a dipole magneti...
