Abstract: A field experiment was conducted during Rabi season, 2005-06 and 2006-07 at the Crop Research Centre of G. 8. Pant University of Agriculture and Technology, Pantnagar to study the effect of integrated nutrient management (INM) on growth, yield and quality of Indian mustard cultivar Kranti. Twelve treatments consisting of 100 and 75 % of the recommended dose of fertilizers (RDF) (120-40-20 kg NP20 K20 ha-1 ) either alone or with successive addition of farmyard manure (FYM), sulphur, zinc, boron and Azotobacter were tested. Application of 100 % recommended dose of fertilizers along with farmyard manure, sulphur, zinc, boron and Azotobacter (seed treatment) resulted in maximum plant height, dry matter accumulation, total branches plant·\', siliquae planr1, seeds siliqua·1 , 1000 seed weight and higher seed yield. The variations in growth and yield between 100 and 75 % recommended dose of fertilizers with farmyard manure, sulphur, zinc, boron and Azotobacter were not significant. Significantly higher oil content was recorded at 75 % recommended dose of fertilizers with farmyard manure, sulphur, zinc, boron and Azotobacter than that of respective ingredients with 100 % recommended dose of fertilizers. Protein content was significantly higher in 100 % recommended dose offertilizers + 2 t FYM + 40 kg S + 25 kg Zn S04 + 1 kg Bha·1 + Azotobacter (seed treatment) compared to 75 % recommended dose of fertilizers. Nutrient concentration in terms ofN, P, K, S, Zn and 8 content in seed and stover were significantly higher at higher 100 % recommended dose of fertilizers and increased significantly at both the fertility levels with each successive addition of farmyard manure, S, Zn, 8 and Azotobacter. Net returns and 8 : C ratio were recorded maximum in 100 % recommended dose of fertilizers + 2 t FYM + 40 kg S + 25 kg Zn S04 + 1 kg B ha-1 + Azotobacter (seed treatment).
