(2024). Experimental crop biomass and gas flux (methane, nitrous oxide, and ammonia) data from continuous and intermittently flooded rice fields under different fertiliser treatments, India, July-October, 2016. NERC EDS Environmental Information Data Centre 10.5285/46aafc00-6742-41df-b8be-09a8d5d86610 This dataset contains rice crop biomass, and greenhouse gas flux measurements from five plots exposed to different fertiliser treatments and continuous and intermittent irrigation protocols. The gas flux data include methane, nitrous oxide, and ammonia, which were measured using chamber methodologies. The dataset also includes irrigation protocols and site environmental properties such as soil pH, bulk density, and texture. Agronomic yields are reported in terms of rice grain and total crop harvests as well as total nitrogen use efficiency. This dataset was created as part of an experiment carried out in rice paddies at the Indian Agricultural Research Institute (Delhi, India) in 2016. The experiment aimed to compare the environmental impacts of continuous and intermittent flooding of rice in relation to methane, nitrous oxide and ammonia emissions and the implications for nitrogen use efficiency and yield.

Data was passed to UKCEH in the UK for further analysis. Rice yields were determined from one square meter of area in each plot in triplicate. The total nitrogen content of the crops was estimated using the Kjeldahl method, for more information please see the supporting documentation. Collection of greenhouse gas samples was carried out using the static chamber technique. Concentrations of methane (CH4) in the gas samples was analysed using a gas chromatograph (GC) fitted with a flame ionization detector (FID)(GC 8A Series, Shimadzu) and nitrogen oxide samples were analysed using a GC with electron capture detector (ECD)(Hewlett Packard 5890 Series II). Emissions of gas were measured using static chambers. Air from chambers was bubbled through 0.01N boric acid solution containing mixed indicator (methyl red and bromocresol green) using a vacuum pump with a flow rate of 3 L/min for 3.5 minutes. The volatilised ammoniacal nitrogen was determined by the titration of boric acid solution with 0.001N sulphuric acid.
