Dayak onion (Sisyrinchium palmifolium L., Syn.: Eleutherine palmifolia L. Merr.) is a typical Central Kalimantan, Indonesia medicinal plant. Optimizing the function of the S. palmifolium is done to increase cultivation and community interest; more fertilization and growth regulator treatments are needed to accelerate plant growth. In this study, the physiological properties of S. palmifolium will be examined regarding fertilization and the IAA (Indole Acetic Acid) hormone. CRD factorial pattern with four levels of fertilization variation (soil; soil + chicken manure (1:1); soil + vermicompost fertilizer (1:1); soil + chicken manure + vermicompost (1:1:1)) and three levels of hormone concentration (0 ppm; 100 ppm; 200 ppm) resulting in 12 treatment combinations which are used in this experiment. It was repeated three times for each therapy. It was shown that the number and length of leaves, the number of flowers and their flowering time, bulb weights, chlorophyll content, and flavonoid levels were all correlated with the number of leaves. The data were examined for significant changes between the treatments using the Analysis of Variant (ANOVA) and Duncan's Multiple Test (DMRT) at a 5% significance level. The physiological and biochemical features were altered by fertilization and the IAA hormone. The IAA hormone and fertilization on S. palmifolium enhanced the number of leaves, their width, the ratio of shoot roots to roots, and flavonoids. The maximum yields of wet weight, dry weight, and leaf carotenoids were obtained with vermicompost (1: 1) and a hormone at 200 ppm (P2H2) adding. Combining vermicompost treatment with the IAA hormone produced the highest level of flavonoids (P2H0).
