The results revealed that application of fertilizers and FYM on STCR basis along with dual microbial inoculation recorded higher grain yield (3740.5 kg ha-1) and straw yield (9485.9 kg ha-1) of ragi. Similarly, the available nutrient status of soil N, P, K, Ca, Mg and S significantly enhanced due to integrated use of fertilizers and FYM on STCR basis along with Azotobacter and phosphorous solubilizing bacteria inoculations. Higher values of N, P, K, Ca, Mg and S content and uptake by ragi crop was noticed in treatment receiving fertilizers and FYM on STCR basis along with dual microbial inoculations. But there was not much significant improvement in physico – chemical properties of soil after harvest of ragi crop. However, organic carbon ranges between 5.1 to 5.4 g / kg. Azotobacter and PSB populations were higher in treatment with fertilizer and organic manure along with dual microbial inoculation (T8) or Azotobacter (T6) and PSB (T7), respectively. Application of fertilizers and FYM on STCR basis along with dual microbial inoculation resulted in higher gross returns, net returns, value added cost ratio, unit cost of production and productivity index compared to all other treatment combinations. The targeted yield in finger millet could be achieved within ±10 per cent deviation with integrated nutrient supply using STCR approach.ennullThesis
