Field experiments were conducted during kharif 2010 and 2011 on turmeric (Curcuma longa L.) variety BSR2 at Regional Research station, Tamil Nadu Agricultural University, Paiyur on alfisol soil with ten treatments. The experiment was laid out with graded levels of nitrogen (150 and 200 kg/ha), Phosphorus (60,75kg/ha) and potassium (108,150 and 180 kg/ha). The pooled results of two years indicated that the growth parameters like the plant height (68.10cm), number of leaves (8.40), leaf length (72.07cm), leaf breadth (18.41cm) and number of tillers (4.20) and the yield characters like weight of mother rhizome (176.80g), weight of primary rhizome (343.42g), weight of secondary rhizome (241.43g) ,weight of clump per plant (846.82g) and fresh rhizome yield (44.43t/ha) were the highest by the application of 200-75-180 kg NPK along with FYM (25t/ha) + Biofertilizer (Azospirillum & Phosphobacteria 10 kg each/ha). The optimum dose of fertilizer to increase the yield of turmeric is 200-75-180 kg NPK/ha whenever the inorganics alone are applied while it is 200-75-180 kg NPK/ha + FYM (25t/ha) + Biofertilizer (Azospirillum & Phosphobacteria 10 kg each/ha) whenever integrated nutrient management practice is adopted.
