Abstract: A field experiment was conducted during 2015 at the college of agriculture, V.C. Farm, Mandya, University of Agriculture sciences, Bangalore to study the effect of sources and levels of sulphur fertilization on soil nutrient status of aerobic rice. The results revealed that the application of different sulphur sources at different rates did not exert any significant influence on pH, available nitrogen, exchangeable potassium and exchangeable calcium content of soil. However the electrical conductivity varied significantly with different growth stages of plant. The organic carbon, available phosphorus, exchangeable magnesium and available sulphur status of soil at 30, 60, 90 days after sowing and at harvest was significantly, higher under RDF + 26 kg sulphur per hectare through ammonium sulphate (T6 treatment). In the effect among sources of sulphur, Ammonium sulphate had a significant influence and relatively better than other sources. As regards to levels the highest nutrient status in soils were recorded with highest level of sulphur application @ 26 kg ha-1.
