Influence of NPK Levels in Conjugation with FYM on Soil Health Properties at Maize Field in Prayagraj District (Zea mays L.)

This field experiment aimed to assess the "Influence of NPK Levels in Conjugation with FYM on Soil Health properties at Maize field in Prayagraj District (Zea mays L.)" at the Crop Research Farm of the Department of Soil Science and Agricultural Chemistry, Naini Agricultural Institute (SHUATS), Prayagraj (U.P.) during the Zaid season 2022. The outcomes demonstrated a considerable impact of NPK and FYM application on the physico-chemical characteristics of the soil. At a depth of 0-15 cm and 15-30 cm, the maximum bulk density (1.26 and 1.37 Mg m-3), particle density (2.65 and 2.71 Mg m-3) and pH (7.36 and 7.44) were recorded in NPK0FYM0, while the minimum bulk density (1.16 and 1.25 Mg m-3), particle density (2.60 and 2.65 Mg m-3) and pH (7.16 and 7.24) were found in NPK100FYM100. Similarly, the maximum EC (0.29 and 0.42 dS m-1), organic carbon (0.74 and 0.52%), percentage pore space (48.52 and 46.31%), water holding capacity (45.28 and 42.60%) and available nitrogen (252.03 and 184.03 kg ha-1), phosphorus (32.65 and 25.83 kg ha-1) and potassium (315.62 and 241.52 kg ha-1) were recorded in NPK100FYM100, while the minimum EC (0.21 and 0.31 dS m-1), organic carbon (0.44 and 0.34%), percentage pore space (44.76 and 40.79%), water holding capacity (39.41 and 36.47%) and available nitrogen (224.52 and 156.52 kg ha-1), phosphorus (22.62 and18.46 kg ha-1) and potassium (273.32 and 189.67 kg ha-1) were recorded in NPK0FYM0. However, the physico-chemical characteristics of the soil were significantly influenced by the application of NPK with FYM.
