Singh, Minu: Mineral Nutrition of Turmeric (Curcuma longa L.)

Herbal medicines are in great demand in both developed and the developing countries because even in many of the modern medicines, the basic composition of drugs is derived from plants due to their easy availability, least side effects, low prices, and long-lasting curative properties. Turmeric (Curcuma longa L.) occupy prominent positions both in ancient and modern systems of medicine. Though India is a major producer of turmeric, the growing on supply demand owing to its nutritive and therapeutic values is putting a heavy strain in the market. To overcome this critical situation, its enhanced production with value addition, if possible, is extra-ordinarily desirable. Thus, it is necessary to improve the techniques of cultivation and increase the per hectare yield of the medicinal and spice crops through balanced nutrition. This work provides valuable information regarding mineral nutrition strategies for the cultivation of this important spice crop. The application of mineral nutrients through roots improves the productivity and quality attributes and production of curcumin content in Curcuma longa L.
