A field experiment was carried during winter season of 2005–06 and 2006–07 to study the effect of integrated nutrient management on productivity, quality, economics and nutrient uptake of mustard [Brassica juncea (L.) Czernj & Cosson] in Indo-Gangetic plains of India. The plant height, total dry matter accumulation, leaf area index and seed and stover yields were recorded significantly higher when recommended dose of fertilizers (RDF) i.e. 120:17.6:16.6:40, N:P:K:S kg/ha was applied along with FYM 10t/ha, 25kg ZnSO₄/ha and seed treatment with Azotobacter. On an average, seed yield of mustard increased by 41.2% over alone application of RDF. Application of either FYM or Zn or seed treatment along with RDF enhanced the mustard seed yield by 12.0, 11.5 and 13.0%, respectively over RDF alone. The inorganic fertilization had adverse effect on oil as well as glucosinolate contents and highest values were recorded at 50% RDF. Additional application of either of FYM or Zn further increased the oil and glucosinolate contents. Azotobacter seed treatment reduced the glucosinolate but improved the oil content. The highest values of N, P, K, S and Zn content and its uptake were recorded with combined application of RDF with FYM, Zn and Azotobacter.
