Agricultural soils managed with a large amount of fertilizer generate nitrous oxide (N 2 O). This study aims to observe the N 2 O flux rates from four organic matter treatments and examining soil water-filled pore space (WFPS) and soil temperature in rainy and dry seasons. The experimental sites took place on a silt loam soil with four organic matter treatments, i.e., 1). No organic matter (OM), 2). Chicken manure, 3). Cattle manure, and 4). Bio-compost. N 2 O fluxes were measured bi-weekly during the rainy season and weekly during the dry season. Soil WFPS and soil temperature were both determine at the same time. N 2 O fluxes from Shallot were significantly different between rainy and dry season (p 45% lead to high N 2 O fluxes and higher soil temperature. This finding showed that water is one of the vital inputs to maintain in order to mitigate N 2 O emission from agricultural soils, whether in upland or lowland.
