The studies on long term effect of application of organic and chemical sources of nutrientsin mustard were conducted at research farm, Department of Soil Science and Agricultural Chemistry, College of Agriculture, Gwalior, (M.P.) during Rabi season of 2020-21 and 2021-22 with nine treatments replicated thrice in randomized block design. The results indicated that the integration of vermicompost @5 t ha^-1 + 50% recommended dose of NPK fertilizers resulted in achieving significantly higher grain yield (2779 kg ha^-1), straw yield (6883 kg ha^-1), (112553₹ ha^-1) and net return (₹79953₹ ha^-1) of mustard pooled basis in comparison to absolute FYM @20t ha^-1 or vermicompost @10t ha^-1 or 100% recommended dose of NPK fertilizers alone or their graded combinations. The benefit: cost ration of mustard was recorded at par under the treatments with integration of FYM @ 5 t ha^-1 with 75 RDF, FYM @ 10t ha^-1 with 50% RDF, vermicompost @ 5 t ha^-1 with 50 RDF, vermicompost @ 2.5 t ha^-1 with 75% RDF and absolute chemical but they were found significantly higher than the treatments with absolute FYM or Vermicompost or their integration with 25% RDF. These findings revealed that the integration of sources of nutrients is better in terms of yield and economics of crop.
