Ratoon Rice Cropping Mitigates the Greenhouse Effect by Reducing CH₄ Emissions through Reduction of Biomass during the Ratoon Season.

ABSTRACT: The ratoon rice cropping system (RR) is developing rapidly in China due to its comparable annual yield and lower agricultural and labor inputs than the double rice cropping system (DR). Here, to further compare the greenhouse effects of RR and DR, a two-year field experiment was carried out in Hubei Province, central China. The ratoon season showed significantly lower cumulative CH₄ emissions than the main season of RR, the early season and late season of DR. RR led to significantly lower annual cumulative CH₄ emissions, but no significant difference in cumulative annual N₂O emissions compared with DR. In RR, the main and ratoon seasons had significantly higher and lower grain yields than the early and late seasons of DR, respectively, resulting in comparab
