Prayitno MB, Dunand H, Sulistyani DP. 2019. The influence of urea fertilizer and zeolite minerals on carbon dioxide (Co2) emissions on the rice plant ( Oryza Sativa L.) in peat soil. In : Herlinda S et al. ( Eds .), Prosiding Seminar Nasional Lahan Suboptimal 2019, Palembang 4-5 September 2019. pp. 437-444. Palembang: Unsri Press. This study aims to determine the effect of nitrogen and zeolite fertilization on CO 2 emissions in paddy rice plantation in peat soils. The study was conducted in the greenhouse of the Faculty of Agriculture, Sriwijaya University, Inderalaya, South Sumatra Province, from September to December 2018. The results of this study indicate that the treatment of nitrogen fertilizer produces the highest CO 2 emissions in the production phase of the U 3 treatment (average emissions: 3.80 mg/plant/day) and the lowest emissions in the vegetative phase (age 55 days) on the U 2 treatment (average emissions: 2.41 mg/plant/day). The zeolite treatment produced the highest CO 2 emissions in the production phase of Z 1 treatment (average emission: 3.82 mg/plant/day) and the lowest emissions in the generative phase (age 65 days) on treatment Z 1 (average emission: 2.43 mg/plant/day). The highest CO 2 emission from the combination of nitrogen and zeolite fertilizers is in the rice production phase U 2 Z 3 (3.95 mg/plant/day) and the lowest CO 2 emission at 55 days on treatment U 2 Z 1 (2.22 mg/plant/day).
