The field experiment entitled “Effect of integrated nutrient management on growth and yield of turmeric cv. Salem” was conducted to know the effect of organic and inorganic sources of nitrogen at varied concentrations (50% RDN and 75% RDN) on the growth and rhizome yield of turmeric cv. Salem. The experiment was planed with eight treatment combinations replicated thrice and allotted in randomized complete block design. The experiment was laid out at Horticulture Farm, College of Agriculture, University of Agricultural Sciences, Raichur, Karnataka, India, during 2016-17. The significant differences were observed among the various treatments. Supplementation of 50% of RDN through inorganic sources remaining 50% of RDN through organic sources as pongamia cake (T7) effected in significantly vigorous growth of the plants which resulted in higher rhizome yield (43.94 t ha-1). It was revealed that higher fresh rhizome yield was the result of significantly higher number of mother rhizomes, primary rhizomes, secondary rhizomes and their significantly higher weight also. However, application of RDN through inorganic sources (T1) as per the RDF resulted in lower fresh rhizome yield coupled with low vigoured plant growth and lower yield parameters.
