MUNAWAR IQBAL1*, DIL MUHAMMAD2, ZIA-UL-HAQ2 AND YASIR JAMIL2, M. RAZA AHMAD2
Abstract: The seeds of garden pea (Pisum sativum L. cv. climax) were exposed to full-wave rectified sumusoidal non-uniform magnetic fields of strength 60 mT, 120 mT and 180 mT for 5, 10 and 15 min prior to sowing. The magnetically treated seeds were sown according to the protocol of International Seed Testing Association (ISTA). Magnetically treated seed showed significant increase in germination. The emergence index, final emergence index and vigor index increased by 86.43%, 13.21% and 204.60%, respectively. It was found that exposure of 5 min for magnetic field strengths of 60 mT and 180 mT significantly enhanced the germination parameters of the pea and these treatments can be used practically to accelerate the germination in garden pea.
