Organic agriculture and greenhouse gases (GHGs) emission are important issues in the Nepalese agricultural system in the context of food security. Agricultural CO2, CH4 and N2O emission in the atmosphere is partly causing climate change. In a global estimation, agriculture sector contributes 10 to 12 percent of the total estimated GHG emissions each year. Large quantities of organic manure added every year to agricultural soils for supplying nutrients, contribute significantly to CO2 emission. In a finding, 38.6 and 18.6% higher carbon emissions were reported from organic amendment of wheat straw and FYM application as compared to chemical fertilizer, respectively. Sequestration of carbon in soil due to organic agriculture has even greater potential to increase organic carbon in the soil. On the other hand, chances of GHGs emission increase with the increase of organic carbon in the soil…………………………………..
