Abstract: Field experiment was conducted at university of Agricultural Sciences, Bangalore during Kharif seasons of 2006 and 2007 under rain fed condition with different organic manures viz., FYM, sewage sludge, poultry manure compost, urban garbage compost, enriched urban garbage compost and vermicompost at the rate equivalent to recommended nitrogen and comparison with inorganic fertilizers to study the effect of different organic manures on nutrient uptake, availability and grain yield of finger millet under rain fed condition. The results indicated that application of sewage sludge recorded higher nutrient uptake (40.5, 8.8 and 31.5 kg of N, P and K/ha, respectively) and its availability after harvesting (258.7 63.7 and 269.2 kg of N, P and K/ha, respectively) and was on par with poultry manure compost. Highest grain yield (1870 kg ha-1) and straw yield (3105 kg ha-1) of finger millet was recorded with application of sewage sludge followed by poultry manure compost (1833 and 3052 kg ha-1, respectively) over all other treatments. The study clearly indicated that use of sewage sludge and poultry manure compost application at equivalent recommended nitrogen dose could be successfully used for Finger millet to substitute the chemical fertilizers are found to be sustainable.
