In this study, the effects of exposing pre-sown pea seeds to magnetic fields on plant growth parameters have been studied under field conditions. Seeds from five different varieties (Javor, Desier, Mamoth, Oregon Sugar Pod, and Purple Pod) were batch exposed to static magnetic fields for 15, 30, and 45 minutes. Then, the magnetically treated seeds were sown in plastic cups and watered under running water. After 30 days of germination, three plants were marked for the collection of morphological data, different plant growth parameters were tested based on normal seedlings, such as root length, shoot length, fresh root weight, dry weight root and shoot dry weight. The results obtained indicated that the fresh weight of the root, the fresh weight of the shoot and the dry weight of the shoot for the varieties were significantly affected by the time of exposure to the magnetic field, as the duration of the magnetic fields increased. All seeds pretreated by magnetic field showed higher root weight, fresh shoot and dry weight compared to the control condition, and the highest root weight and fresh shoot was reported by treating seeds for 45 minutes under magnetic field conditions. However, the highest shoot dry weight was reported by seed treatment for 30 min. The reports indicated that the application of magnetic fields improved the growth characteristics of the treated group compared to the unexposed group.
