A field experiment was conducted in Vertisol at Water Management Research Center, Belavatagi in Malaprabha Command during rabi 1999-2000 to study the integrated effect of organic and inorganic sources of nutrients on uptake of nutrients by sunflower and their availability after harvest. The organic sources included were maize residue, cotton stock, FYM each @ 5 t ha-1 and vermicompost @ 2 t ha-1. The inorganic fertilizer levels were 0, 50, 75 and 100 % recommended dose of fertilizer. The highest uptake of NPK was recorded in vermicompost treatment followed by FYM, cotton stock and maize residue. Among inorganic fertilizer 100 per cent RDF has given highest uptake of NPK followed by 75 and 50 per cent RDF. Available N, P, K and S in soil at harvest of crop was highest with application of vermicompost @ 2 t ha-1 followed by FYM. Among the fertilizer levels, 100 per cent RDF has given higher available N, P, K and S than at lower levels of fertilizer.
