Abstract: Field experiment was conducted at University of Agricultural Sciences, Bangalore with an objective to enhance productivity of finger millet intercropping in organic system of production during Kharif 2006 and 2007. Different organic manures at 50 kg N equivalent used in the experiment are FYM, sewage sludge, poultry manure compost, urban garbage compost, enriched urban garbage compost and vermicompost compared to inorganic fertilizers alone. Irrigation water was provided during dry spells throughout the crop growth period. Results indicated that grain yield of Finger millet (2498 kg ha-1) and pigeonpea grain (370 kg ha-1) were significantly influenced by application of sewage sludge followed by poultry manure compost. It also recorded greater soil microbial population viz., bacteria (23.54 x 107 cfu/g), fungi (25.65 x 104 cfu/g), actionomycetes population (23.04 x 103 cfu/g), microbial biomass carbon (2131.8 mg/g) and microbial biomass N (239.7 mg/g of soil), followed by poultry manure compost and lowest in inorganic fertilizer. Organic sources of nutrients improved soil physico-chemical properties viz, bulk density, water holding capacity, porosity and organic carbon. The highest organic carbon content was noticed with the application of sewage sludge (0.68%) followed by poultry manure.
