Effects of biochar and barley straw application on the rice productivity and greenhouse gas emissions of paddy field

Abstract To improve the agricultural environment, utilization of biochar and organic materials from paddy fields gaining importance. This is because long-term use inorganic fertilizers aggravates soil also rice a major source CH 4 N 2 O emissions during cultivation which involves continuous flooding. Recently, application to has received increasing attention due their potential benefits related quality, crop growth, greenhouse gas emission. study examines influence straw treatments on physicochemical properties, global warming in field. Five were applied for study: control (Cn), fertilizer (IF), barley (BC), (BS), BC + BS. Soil quality after harvesting improved treated group. The yield components BS, compared other treatments. These effects resulted increased uptake nutrient contents BS treatment. Total fluxes relative significantly decreased by 37.3% 65.2% group than IF treatment, respectively. Consequentially, cropping system with an effective strategy productivity reduce GHG fields, thereby alleviating warming.
