Nitrogen and sulfur are essential macronutrients in plant growth development, their interaction profoundly influences gene expression, metabolic activities, adaptability plants, directly affecting yield. Garlic (Allium sativum L.) is a crop of significant economic medicinal value. However, despite the critical role nitrogen–sulfur garlic’s adaptability, yield, quality, specific mechanisms underlying these effects remain unclear. In this study, transcriptomic metabolomic analyses were employed to investigate combined nitrogen application on garlic bulb tissues. The results show that significantly increased diameter weight bulbs by 14.96% 35.47%, respectively. content alliin 28.48%, while levels abscisic acid (ABA), jasmonic (JA), salicylic (SA), gibberellin (GA) 15.82%, 12.94%, 32.34%, 48.13%, Additionally, activities alliinase, superoxide dismutase (SOD), catalase (CAT) enhanced 7.93%, 4.48%, 19.74%, Moreover, reduced malondialdehyde (MDA) peroxidase (POD) activity 29.66% 9.42%, respectively, thereby improving potential. Transcriptomic analysis revealed differentially expressed genes several key pathways, including hormone signal transduction, RNA degradation, glutathione metabolism, amino biosynthesis, glycerophospholipid metabolism. Metabolomic identified 80 abundant metabolites primarily consisting acids, indole carboxylic fatty acids. integrated highlighted pivotal roles biosynthesis pathways synergistic nitrogen. This study not only provides scientific evidence for understanding interaction’s impact yield quality but also offers basis optimizing nutrient management strategies enhance quality.
