Abstract A field experiment was conducted on Turmeric (Curcuma longa L.) with a variety of Azad Haldi-1 during 2011–12 and 2012–13 on sandy loam soil at HRC of Sardar Vallabhbhai Patel University of Agriculture and Technology, Meerut. The experiment aimed to evaluating the effect of different sources of nutrients (organic and inorganic) on the productivity and quality (essential oil and curcumin %) of turmeric. The experiment was laid out in the randomized block design with 10 treatments and 3 replications. The treatments comprised the T1 (Control), T2 (100% RDF NPK), T3 (125% N + RDF PK), T4 (125% P + RDF NK), T5 (125% K + RDF NP), T6 (125% NPK), T7 (100% NPK + FYM @ 20 t ha−1), T8 (75% NPK + FYM @ 30 t ha−1), T9 (50% NPK + FYM @ 50 t ha−1) and T10 (25% NPK + FYM @ 80 t ha−1). The study indicated that turmeric showed better response of the application of 125% NPK or 100% NPK + FYM @ 20 t ha−1 on yield attributes like primary fingers, secondary fingers, mother rhizomes over control as a results significantly higher yield was noticed under these treatments. Impact of different sources (Organic and inorganic) of nutrients were also studied on quality parameters like essential oil and curcumin percent and it was found that more essential oil and cur cumin was noticed in these treatments over control. The study thus suggests that application of balance mineral fertilizer @ 125% NPK of RDF or in combination with FYM i.e. 100% NPK + FYM @ 20 t ha−1 gave higher crop production and more essential oil and curcumin under sandy loam soil.
