However, its naturally high potassium content can be problematic for individuals with impaired kidney function and related diseases. To produce low‑potassium basil by modifying the nutrient solution composition, basil cultivation was conducted under the hydroponic system in closed plant factory. We evaluated four treatments (N1K1, N1K0, N2K2, and N2K0) for their effects on basil growth, volatile organic compound (VOC) profiles, and antioxidant capacity (via ABTS assay) and conducted one-way analysis of variance (ANOVA) followed by Duncan’s multiple range test and Student’s t-test (using N1K1 as the control) to assess significant differences. After 21 days, all long‑term treatments increased plant biomass and significantly raised eugenol and other VOC levels compared to the control. Notably, the N1K0 treatment significantly enhanced total phenolic and rosmarinic acid content, achieving the highest ABTS activity. This approach offers a novel strategy for producing low‑potassium basil, while also improving yield and functional quality.
