Descrição: Rice (Oryza sativa L.) production in the future aims to increase productivity every year with high input technology, including irrigated rice. However, the practices of irrigated rice fields have a high methane (C[H.sub.4]) production potential. Soil tillage could affect C[H.sub.4] emission conditions. Puddling and flooding through soil tillage create reduction conditions that promote C[H.sub.4] production by methanogenic bacteria. The objective was to determine the effect of soil tillage and N fertilizer management on C[H.sub.4] emissions from rice fields with heavy-textured soil. The field experiment was arranged in a split-plot design in which soil tillage was the main plot and consisted of maximum tillage and no-tillage. Nitrogen fertilizer management was the split plot and consisted of a control without N, prilled urea broadcasting, prilled urea deep placement, ammonium sulfate (AS) broadcasting, AS deep placement, and tablet urea deep placement. No-tillage could reduce C[H.sub.4] emissions by 15.58% compared with maximum tillage. However, grain yield for no-tillage was lower than for maximum tillage with 2.73 and 3.68 t [ha.sup.-1], respectively. The AS and tablet urea deep placement emitted lower C[H.sub.4] and grain yield was higher than with other N management practices. The C[H.sub.4] emissions for AS and tablet urea deep placement was 96 and 97 kg C[H.sub.4] [ha.sup.-1] season (1) and grain yield was 3.79 and 4.25 t [ha.sup.-1], respectively. The application of fertilizers incorporated into the soil increased rice productivity and mitigated C[H.sub.4] emissions from rice fields. Key words: Maximum tillage, methane emissions, nitrogen fertilizer, no-tillage, Oryza sativa, rice fields.
