Effect of Nitrogen and Sulphur Supplementation through Organic Sources on Soil Properties in the Bundelkhand Region of Uttar Pradesh

The integrated use of mineral fertilizers and organic materials is widely recognized as a sustainable approach for crop production. A field experiment was conducted in the nursery organic farm at Karguwanji, Bundelk-hand University, Jhansi, Uttar Pradesh, during the Rabi season of 2019-20 to evaluate the effect of nitrogen and sulphur supplementation through organic sources on soil properties in tomato (Solanum lycopersicumL.). The experiment comprised nine treatments laid out in a Randomized Block Design (RBD) with threereplications. The results revealed a significant influence of organic sources on soil chemical properties.Soil pH was not significantly affected by the treatments. Electrical conductivity (EC), available phosphorus,and available potassium reached their highest values in treatment $T_8$ (50% Vermicompost + 50% FarmYard Manure + 30 kg/ha S). Available nitrogen was highest in T1 (100% FYM), whereas available sulphur washighest in the Recommended Dose of Fertilizers (T0).
