Effect of Organic Sources of Nitrogen on Rice (Oryza sativa) and Soil Carbon Pools in Inceptisols of Jammu

摘要

A pot experiment was conducted during Kharif season, 2005 to ascertain the response of different organic sources viz., wheat straw, farm yard manure (FYM), vermicompost and poultry manure to rice (Oryza sativa) and also to monitor the effect of manuring on soil carbon pools. Application of poultry manure and vermicompost alongwith chemical fertilizers for supply of nitrogen, phosphorus and potassium (NPK) resulted in highest grain yield rice. Soil carbon, labile carbon and water soluble carbon contents also improved with application of organic sources of N application.
