A field study was conducted on the “Effect of NPK Levels and Micronutrients with and without Liquid Biofertilizer on Soil Health and Yield Attributes of Maize (Zea Mays L.)” Cv. K-25” at the Soil Science & Agricultural Chemistry Research Farm, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj during Kharif season 2018 and 2019. The soil of experimental area falls in order Inceptisol and soil texture was sandy loam. The result showed that in treatment T19[140:80:50 NPK kg ha-1 + Zn (20 kg ha-1) and Mn (25 kg ha-1) + Azotobacter (200 ml ha-1)+ PSB (200 ml ha-1)] bulk density (1.17 Mg m-3 during 2018, 1.11 Mg m-3 during 2019), particle density (2.32 Mg m-3 during 2018, 2.49 Mg m-3 during 2019), pore space (47.54 % during 2018, 48.87 % during 2019), water holding capacity (39.75 % during 2018, 39.95 % during 2019), Soil texture (58, 30, 12 % sand, slit, clay during 2018 and 2019), Soil colour (10 YR 6/3 pale brown and 10 YR 4/3 dark brown during 2018 and 2019), pH 6.99 during 2018, 7.67 during 2019, EC (0.87 dSm-1 during 2018, 0.80 dSm-1 during 2019), organic carbon (0.35 % during 2018, 0.50 % during 2019), available nitrogen (290.87 kg ha-1 during 2018, 317.58 kg ha-1 during 2019), available phosphorus (22.39 kg ha-1 during 2018, 22.28 kg ha-1 during 2019), available potassium (291.94 kg ha-1 during 2018, 269.52 kgha-1 during 2019), available zinc (0.84mg kg-1during 2018, 0.85 mg kg-1during 2019), available manganese (5.35mg kg-1during 2018, 5.66 mg kg-1during 2019)as compared to T0 (absolute control).
