The study was undertaken to evaluate the long-term effect of organic management practices against integrated use of nutrient sources and chemical fertilizer treatments on mustard productivity and soil fertility. The integrated use of nutrient sources viz., 50% recommended doses of NPKS through chemical fertilizer and 50% N through FYM provided highest seed yield, yield attributes and total uptake of N, P, K which was at par to the 100% chemical fertilizer (NPKS) treatment. The organic treatments received 100% recommended N combindly through FYM + neem cake + vermicompost (1/3 from each source) along with different management practices provided lower yields. The reduction in dose of nutrients (50% FYM along with bone meal, PSB and Azotobacter) provided significantly lower yield and nutrient (NPK) uptake. The regular application of 100% nutrients through organic sources (FYM + VC+ NC) showed appreciable increase in organic carbon and availability of nutrients (NPK) and higher decline in soil pH and EC as compared to INM and fertilizer treatments. The availability of nutrients in 100% NPKS through chemical fertilizers and INM treatment was at par. The higher profit was obtained in INM treatment followed by 100% chemical fertilizer treatment. The conjunctive use of organic sources and fertilizer (INM) proved conducive in sustaining soil fertility and productivity of mustard in long run.
