Abstract
This study was conducted to investigate CH4 emission as influenced by different organic matter forms from rice straw applied to paddy field (Eutric Fluvisols) planted with rice culivar Khang Dan 18 in the Spring and Summer seasons of 2015 and 2016. Keeping inorganic NPK level constant (100 kg N, 80 kg P2O5 and 80 kg K2O/ha), organic matter amendments included chopped rice straw (4500 kg/ha1), biochar produced from rice straw and compost (produced from 4500 kg rice straw). The emission rates of CH4 were measured by using the closed chamber method. Results showed that CH4 emission rates differed markedly with the forms of organic matter application. Pure application of mineral fertilizers yielded lowest CH4 emission rate but highest rice grain yield. In contrast, amendment with chopped rice-straw resulted in highest CH4 emission rate and lowest rice grain yield. Biochar and compost application lowered CH4 emission rate as compared with rice straw amendment. However, application of compost maintained rice yield comparable to mineral fertilizer.
