A Field experiment was conducted at Agricultural Research Station, Dhadesugur on deep black soil during rabi-2017. The experiment was replicated thrice in split plot design. There were ten treatment combinations consisted of tillage practices in main plot and nutrient management practices in sub plot. Among the main plot treatments, conventional tillage recorded significantly higher uptake of nitrogen, phosphorus and potassium (40.11, 17.15 and 38.38 kg ha-1, respectively), and bacterial, fungal and actinomycetes (65.5 CFU × 10-6 g-1, 21.9 CFU×10-4 g-1 and 37.5 CFU×10-3 g-1, respectively) population over reduced tillage. Among sub plot treatments, application of recommended dose of fertilizer with FYM recorded significantly higher uptake of nitrogen, phosphorus and potassium (47.31, 22.14 and 44.96 kg ha-1, respectively) and bacterial, fungal and actinomycetes (82.7 CFU × 10-6 g-1, 28.3 CFU×10-4 g-1 and 47.5 CFU×10-3 g-1, respectively) population over all other treatments. Interaction of main and sub plot treatments, significantly higher uptake of nitrogen, phosphorus and potassium (50.38, 22.64 and 46.96 kg ha-1, respectively) and bacterial, fungal and actinomycetes (83 CFU × 10-6 g-1, 28.7 CFU×10-4 g-1 and 49.0 CFU×10-3 g-1, respectively) population were observed in conventional tillage along with recommended dose of fertilizer and FYM compared to all other treatments. Whereas, significantly higher available of nitrogen, phosphorous and potassium content in soil (155.3, 54.3 and 290.6 kg ha-1, respectively) was observed in reduced tillage with organic nutrient management practices. Conventional tillage with unfertilized control recorded significantly lower available of nitrogen, phosphorous and potassium content in soil (115.1, 46.5 and 271.5 kg ha-1, respectively).
