The soil of experimental field was silty clay loam in texture; acidic in nature; high in organic carbon; low in available nitrogen; medium in available phosphorus and potassium. The experiment was laid out in randomized block design with three replications, consisting of seven treatments i.e., 10 t ha-1 FYM + 5% Jeevamrit, 10 t ha-1 FYM + 10% Jeevamrit, 50% recommended N + 10 t ha-1 FYM + 5% Jeevamrit, 50% recommended N 10 t ha-1 FYM + 10% Jeevamrit, seed treatment with Beejamrit + 5% Jeevamrit, seed treatment with Beejamrit + 10% Jeevamrit and recommended NPK through inorganic sources. Integration of nutrients using 50% recommend N + 10 t ha-1 FYM + 10% Jeevamrit resulted in better plant height (cm), number of plants/tillers (m-2 ), leaf area index, dry matter accumulation (g m-2 ), yield attributes with higher grain yield (4.08 and 4.22 t ha-1 ), stover/straw (6.72 and 7.28 t ha-1 ) yield and primary (NPK), secondary (Ca, Mg, S) and micronutrients (Zn, Fe, Cu, Mn, B) content and uptake by both maize and wheat crops. Soil properties viz., soil pH, bulk density, organic carbon, available primary (NPK), secondary (Ca, Mg, S), micronutrients (Zn, Fe, Cu, B), viable microbial count (bacteria, actinomycetes, fungi) and microbial biomass carbon was increased with 50% recommended N + 10 t ha-1 FYM + 10% Jeevamrit application. Application of recommended NPK resulted in higher mean net returns of maize and wheat 39.29 (₹ x 103 ) and 52.64 (₹ x 103 ) and B:C ratio of 1.11 and 2.33, respectively.EnglishThesis
