A field experiment was conducted at Zonal Agricultural Research Station, University of Agricultural Sciences, Gandhi Krishi Vignana Kendra, Bangalore during 2017 to study the effect of nutrient management practices through organics on soil biological properties of sunflower grown on alfisols of eastern dry zone of Karnataka. There were nine treatment combinations laid out in factorial randomized complete block design and replicated thrice. Among different treatment combinations application of FYM at 150 per cent N equivalent and jeevamrutha at 1500 L ha-1 recorded significantly higher bacterial, fungal, actinomycetes, P-solubilizer and N-fixer population at harvest of sunflower (37.67 × 106, 28.33 × 104, 48.50 × 103, 30.10 × 105and 24.50 × 105CFU g-1respectively). The dehydrogenase activity was also examined at peak flowering stage of crop growth and it was found to be higher with application of FYM at 150 per cent N equivalent and jeevamrutha at 1500 l ha-1 (50.11 µg TPF formed/ g of soil/ day). Seed yield and oil content of Sunflower were found higher at increased level of FYM and jeevamrutha application.
