A field experiment was conducted at the AICRP on Integrated Farming System Field, Department of Soil Science and Agriculture Chemistry, Vasantrao Naik Marathwada Krishi Vidyapeeth, Parbhani during rabi season 2019-20 to assess Influence of INM on soil physico- chemical properties in wheat (NIAW-1994) under vertisol. The experiment was laid out in randomized block design with seven treatments and three replications. Results revealed that highest grain yield (2496.24 kg ha-1) and straw yield (4375.47 kg ha-1) recorded in the treatment T6- 25% RDF through chemical fertilizer + 100% RDF through organic manures. The lowest bulk density, particle density (1.14 Mg m-3, 2.21 Mg m-3) respectively, highest porosity (48.11 %), slightly neutral pH (7.40) and lowest electrical conductivity (0.17 dSm-1) found in the treatment T1- 100% RDF through organic manures followed by treatment T6- 25% RDF through chemical fertilizer + 100% RDF through organic manures. The highest organic carbon, available nitrogen, phosphorous, potassium (7.52 g kg-1, 220.69 kg ha-1, 18.67 kg ha-1, 700.00 kg ha-1) respectively and lowest calcium carbonate (3.58 %) was found in the treatment T6- 25% RDF through chemical fertilizer + 100% RDF through organic manures followed by T5- 25% RDF through chemical fertilizer + 75% RDF through organic manures. Combine application of organic and inorganic nutrient sources with RDF suggested for soil physico- chemical properties
