This study investigated the impact of static magnetic field (SMF) treatment and elemental enrichment on the germination, growth and nutritional quality of mung beans. The seeds were hydrated for 12 h followed by a 4-day germination period. The effects of different SMF strengths and exposure stages, as well as the concentrations and volume ratios of the exogenous elements selenium (Se) and chromium (Cr 3+ ) during hydration, on germination percentage, germination index, and seedling length were systematically evaluated. The results showed that higher SMF strengths (10 mT) applied during the final hydration stage (SMF-F) improved seed germination, and that lower concentrations of Se (4 mg/L) and Cr (20 mg/L) also promoted germination. A mixed element treatment with Se: Cr at a volume ratio of 1: 2 resulted in a 1.30-fold increase in germination potential and a 1.25-fold increase in germination index compared to the control. In terms of nutritional quality, SMF treatment and elemental enrichment prior to germination increased levels of protein, amino acids, and phenolic compounds while decreasing vitexin content. An antagonistic effect between Se and Cr enrichment was observed. Overall, SMF treatment combined with a mixed element enrichment effectively enhanced the germination, growth and nutritional quality of mung bean sprouts.
