Field experiment, at Regional Research Station, Bijapur on Typic Chromustert for ten years from 1984–94 indicates that in situ incorporation of sunhemp reduced the bulk density as compared with fertilizer application. Application of sunhemp in combination with fertilizers improved the infiltration rate, water stable aggregates, porosity, field capacity and maximum water holding capacity under drylands. Continuous application of organics increased the CEC and exchangeable calcium while a decrease in Na and CaCO3 was observed. Available nitrogen, phosphorus, potassium and micronutrients increased significantly with organic sources of nutrients either alone or in combination with fertilizers over the fertilizers alone.
