Improving bulb yield, minerals and quality is a major challenge in garlic bulb production. In this study, the effects of irrigation and nitrogen fertilization on the quality and mineral content of garlic cultivar Solan Selection were investigated. The research was conducted over two consecutive winter seasons in 2016-17 and 2017-18, utilizing 12 different treatment combinations in a Factorial Randomized Block Design with three replications. The results indicated that increased nitrogen input led to a significant improvement in total soluble solid (TSS) and dry matter yield, resulting in higher garlic bulb yields. Similarly, an increased irrigation schedule also improved TSS and dry matter yield in garlic bulbs. Furthermore, the interaction between irrigation schedule and nitrogen fertigation had a positive impact on TSS and dry matter yield across cropping seasons. Combining increased nitrogen input and irrigation further enhanced TSS and dry matter yield, although there was no significant improvement in dry matter content and mineral (N, P, K, Ca, Mg, and S) contents in garlic bulbs. The study also revealed a strong positive correlation between nitrogen input and irrigation schedule concerning quality and mineral contents. These findings suggest that adopting high nitrogen input practices (100% of RDN) with increased irrigation (IW/CPE=1.2) can enhance garlic cultivar Solan Selection's dry matter yield, quality, and mineral content
