- ABSTRACT Indonesian government efforts to realize the sustainable food self-sufficiency is through rice cultivation on rainfed area. Rice cultivation used high yield rice variety and site specific nutrient management (SSNM) aim to improve fertilizer efficiency and reduce N2O emission from rainfed area. The study was conducted on growing season 2015-2016 at Research Station of Indonesian Agriculture Environment Research Institute with rice varieties and fertilization treatments. Five rice varieties were used for this study, namely Inpago 8, Towuti, Batutegi, Inpari 14 and Situ Bagendit as control. Fertilization using SSNM based on Permentan No. 40/OT.140/4/2007 and the existing farmers. Dosage of fertilizer used by district of Jaken Pati is organic fertilizer (manure) 2 ton/ha, Urea 325 kg/ha, SP-36 50 kg/ha, KCl 30 kg/ha. Dosage of fertilizer existing of farmers use manure 4 ton/ha, Urea 250 kg/ha, SP-36 100 kg/ha and KCl 100 kg/ha. The results showed that Situ Bagendit variety in SSNM produced the lowest N2O emissions (0.88 kg/ha/season).
