In the present study Bovine digesta, a major slaughter house waste has been recycled as organic fertilizer. Bovine digesta collected was sun dried for 3 days, powdered and was subjected to physicochemical analysis - BOD, COD, pH and TDS. Bovine digesta has 1.35% Nitrogen, 0.72% Phosphorous and 0.515% Potassium. Hence, it has been evaluated as organic fertilizer in Maize at various percentages like 75%, 100%, 125% and 150% equated with nitrogen content of urea. Urea and farmyard manure has been used as inorganic and organic fertilizer control for Bovine digesta. The plant growth parameters - height, number of leaves, leaf breadth, stem breadth and number of cobs have been studied at 45th and 90th day. Also the pattern of nutrient release (Nitrogen, Phosphorous, Potassium and Carbon) from bovine digesta to soil has been studied by analyzing the soil samples at regular intervals (7, 14, 21, 28, 45 and 90th day). The nutrient content (Nitrogen, Phosphorous and Potassium) in tissues - leaves, stem, root and cobs have also been analyzed. In the present study soil NPK release, Productivity (number of Cobs) and NPK content in cobs was comparable with urea and farmyard control when bovine digesta was added as organic fertilizer.
