This study aimed to analyze the effects of ferrite and neodymium magnetic fields on the germination and early growth of yellow dragon fruit (Selenicereus megalanthus) seeds. Conducted over 28 days, the research employed a non-factorial Completely Randomized Design (CRD) with three treatments: a control without a magnetic field (PK), a 1500 µT ferrite magnetic field (PF), and a 2200 µT neodymium magnetic field (PN), each comprising 10 replicates (30 experimental units). Parameters included the number of germinated seeds, germination rate, germination capacity, root length, and shoot length on days 7, 14, 21, and 28. Data were analyzed using One-Way ANOVA (α=0.05), followed by Tukey’s HSD test. Results demonstrated that magnetic field treatments exerted a highly significant effect on all observed parameters (p<0.001). The PN treatment produced the highest responses: an average of 3.70 germinated seeds, 92.50% germination capacity, 0.868 cm root length, and 2.437 cm shoot length by day 28. The PF treatment yielded 2.60 germinated seeds, 65.00% germination capacity, 0.593 cm root length, and 1.665 cm shoot length. The control exhibited the lowest values. Tukey’s HSD confirmed significant differences among all groups, reflecting a response pattern of PN > PF > PK. The 2200 µT neodymium magnetic field proved most effective in enhancing germination and early growth. These findings highlight magneto-priming as a viable, non-chemical physical approach for efficient seedling production. The consistent growth response under neodymium treatment indicates enhanced seedling vigor throughout the observation period. Future research should assess varying intensities and exposure durations to optimize treatments. This study provides an experimental foundation for integrating magnetic field-based seed treatments into sustainable horticulture.
