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 Farm yard manure (FYM), sewage sludge, poultry manure compost (PMC), urban garbage compost, enriched urban garbage compost and vermicompost (VC) compared to inorganic fertilizers alone. Irrigation water was provided during dry spells throughout the crop growth period. Application of sewage sludge recorded highest Soil microbial population viz., bacteria, fungi, actinomycetes population ,microbial biomass carbon and microbial biomass N (23.54 X 107 cfu/g, 25.65 X 104 cfu/g and 23.04X103 cfu/g, 2131.8 mg/g and 239.7 mg/g of soil, respectively) followed by poultry manure compost and lowest in inorganic fertilizer. Organic sources of nutrients tended to improve 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. Significantly higher grain and straw yield of Finger millet (2498 and 4075 kg ha-1 respectively), redgram grain and stalk yield (370 and 1407 kg ha-1) was recorded with application of sewage sludge followed by poultry manure compost over all other treatments.
