Magnetic field treatment is gaining attention for enhancing seed performance and plant productivity in sustainable farming practices. The present study explored the influence of magnetic field exposure on the germination and early seedling growth of cowpea (Vigna unguiculata L. Walp.) and coriander (Coriandrum sativum L.). Seeds were subjected to four magnetic field intensities (M1-M4) generated by permanent round magnets for continuous conditions throughout the experimental period, while untreated seeds served as the control. After 15 days, the growth parameters, including root, shoot, and leaf lengths, were measured under controlled greenhouse conditions. The results demonstrated a significant increase in all measured parameters in magnetically exposed seeds compared with the control. In V unguiculata, M4 resulted in root (6.46 ± 0.7 cm), shoot (8.28 ± 0.5 cm), and leaf (7.56 ± 0.3 cm) lengths, while in C. sativum, seedlings reached root (8.35 ± 0.5 cm), shoot (11.28 ± 1.1 cm), and leaf (4.54 ± 1.8 cm) lengths. These results demonstrate that static magnetic field treatment can effectively enhance germination and early seedling growth, offering a practical approach to support crop production.
