Abstract:
The turmeric (Curcuma longa L.) is an important medicinal spice crop. There are several secondary metabolites like Curcumin, Anti-oxidants, Flavonoids, Alkoloids, Poly-phenols, Saponins, Terpenoids, Essential oils and Oleoresins are present in turmeric. The concentration of the various secondary metabolites strongly dependent on the growing conditions, season, various biotic and abiotic stress conditions and growth stage which has impact on the metabolic pathways responsible for the accumulation of the related natural products.The present research was carried out to standardize the growth stage of turmeric for the potential harvest of secondary metabolites. The experiment consisted of six treatments, which includes different stages of harvesting from 4^th months after planting to maturity and data was analysed by Completely Randomized Design. The secondary metabolites are increased with advancement of maturity. The maximum potential harvest of secondary metabolites from fingers was found at the maturity of turmeric.
