Turmeric being an economically important spice crop with lots of export potential and domestic demands has intensive cultivation requirements especially in terms of nutrients. A field experiment to study the influence of fertigation of N and K fertilizers on quality of turmeric (Curcuma longa L.) cv. BSR 2 was carried out during June 2007 to February 2008, at the Agricultural Research Station, Bhavanisagar, Erode district. The experiment consisted of seven treatments replicated four times in a Randomized Block Design. Among the several treatments, the treatment with 100 % level of N and K application by fertigation through water soluble fertilizers (T5) were recorded higher quality contents viz., curcumin (4.4%), oleoresin (9.6%) and essential oil (3.8%).
