Dynamics of nitrous oxide (N2O) emission and the relationship of soil properties with N2O emission were studied from the tea ecosystem of North East India situated at north bank plain agroclimatic zone at Tezpur, Assam. The gas samples were collected from the tea bush at weekly intervals from 30 August 2008. Our results shows that N2O fluxes from the tea garden planted with varieties Hilika and TV-23 ranged from 7.51 to 63.30 μg N2O-N m–2 h–1. Seasonal N2O emission from Hilika and TV-23 was 46.13 and 55.17 mg N2O-N m–2 respectively. N2O emission showed a relation- ship with soil moisture, soil temperature and soil NO–-N of the experimental field. Soil moisture and soil 3 temperature were found to be the main variables influencing N2O emission from the tea ecosystem.
