The treatments comprised of 3 different types of organic manures viz., farm yard manures, vermicompost and poultry manure and 4 levels control, 4 kg/m 2 , 5 kg/m 2 and 6 kg/m 2 . The experiment was carried out in the split plot design with three replications. Observation on organic carbon, Original Research Article
