This study investigates the effects of silver nanoparticles (Ag NPs), biogenic silver nanoparticles derived from Rhizopus spp. (R.Ag NPs), and Rhizopus (R) elicitors on the yield and bioactive compounds of turmeric (Curcuma longa) using foliar spray and rhizome dipping techniques. Elicitors applied at concentrations of 10, 50, and 100 ppm over 210 days significantly enhanced turmeric yield, phenolic, flavonoid, antioxidant, and curcuminoid content compared to control plants. Among the treatments, Rhizopus culture at 50 ppm applied via foliar spray resulted in a 3.5% increase in curcuminoid content, while rhizome dipping at the same concentration led to a 3.75% increase. These findings suggest that foliar spraying and rhizome dipping with Rhizopus elicitors can effectively enhance turmeric quality, offering potential for improving crop production and curcuminoid yield.
