Abstract: Integrated use of plant nutrients aim at combined application of inorganic and organic sources to improve efficiency of applied nutrients, reduce environmental hazards and improve crop productivity. The present experiment was conducted during kharif-2018 at ARS, Dhadesugur, Karnataka, India to evaluate the integrated plant nutrient supply system on growth, yield and economics of dry-DSR with nine treatments and three replications. Among the IPNS imposed treatments, the treatment T9 (125% RDF + FYM @ 6 t ha-1 + biofertilizers @ 12.5 kg ha-1 + foliar spray of 19:19:19 (1%) at 45, 60 and 75 DAS) exerted significant higher grain and straw yield (7,461 and 8,808 kg ha-1, respectively) as compared to other treatments. The economic analysis revealed that integrated use of inorganic, organic and biofertilizers along with foliar spray of 19:19:19 (1%) at 45, 60 and 75 DAS gave higher gross return, net return and BC ratio (` 151215 ha-1, ` 98756 ha-1 and 2.88, respectively).
