This is the data collected for daily methane emission, root and yield attributes of four (4) rice cultivars under irrigated systems in Latin America and the Caribbean (LAC). The experiment was conducted at the International Center for Tropical Agriculture (CIAT), Palmira, Colombia in 2019; to determine which of the cultivars produce less methane without grain yield compromise. Data were collected to generate information on the role of the root and yield attributes towards methane mitigation strategy under irrigated system. The data is been processed for manuscript publication.


Steps to reproduce

Grain yield and yield attribute data were collected at maturity from the net plot. Dry weight was determined using five (5) hills per plot from the gross plot at four (4) growth stages of active tillering, maximum tillering, 50% flowering and maturity. Daily methane emission were determined between 0 and 45 minutes using closed chamber method from 23 to 107 days after transplanting the field. These methane emissions were captured in vials and gas chromatography was used to determine the concentrations.
