• Cultivar-specific methane emissions and yield-scaled greenhouse gas intensity responses to transplanting date: a case study in South Korea (2026) · Scientific Reports · doi

  There is a need to identify transplanting schedules that reduce methane emissions from flooded rice paddies without reducing grain yield. The effects of transplanting date on methane emissions and yield-scaled greenhouse gas intensity in rice cultivation are not well understood. The study aims to address this knowledge gap and contribute to the development of strategies for mitigating methane emissions from flooded rice paddies.

• Cultivar-specific methane emissions and yield-scaled greenhouse gas intensity responses to transplanting date: a case study in South Korea (2026) · Scientific Reports · doi

  Further research is needed to investigate the effects of other factors, such as soil type and fertilizer application, on methane emissions from flooded rice paddies. The study's findings should be validated over longer periods and in different environments. Additional research is needed to develop and optimize strategies for mitigating methane emissions from flooded rice paddies.
