This research investigates how different fertilization strategies influence the accumulation of lutein and zeaxanthin in sweet corn grown in the Crișului Negru Meadow. The experimental design included four treatment variants: a non-fertilized control variant, a compost-based organic fertilized variant, a mineral-fertilized variant with NPK complex fertilizer, and a combined variant consisting of NPK supplemented with microelements. Carotenoid concentrations were determined by high-performance liquid chromatography (HPLC). The data obtained contribute to a better understanding of the relationship between fertilization practices and the nutritional profile of sugar maize, highlighting the potential of organic nutrient management in increasing the concentration of phytochemicals with beneficial effects on health. Keywords: lutein and zeaxanthin, organic fertilization, carotenoids, HPLC chromatography.
