Resumo: Agronomic practices that help farmers to raise yield and reduce costs must be studied to ensure agricultural sustainability. Thus, the objective of this study was to analyze economically the effect of soil management and nitrogen fertilization in maize crops. Treatments consisted of a combination of 3 soil management techniques (plow harrows + floating harrows, chisel + floating harrows, and no-tillage), 5 periods of nitrogen fertilization (control - 0 kg ha-1 N; 120 kg ha-1 after sowing (S); 120 kg ha-1 in the V6 stage; 30 kg ha-1 (S) + 90 kg  ha-1 in V6; 30 kg ha-1 (S) + 45 kg ha-1 in V4 + 45 kg ha-1 in V8. The total operating cost (TOC), gross revenue (GR), operating profit (OP), profitability index (PI), break-even yield, and break-even price were estimated. It was concluded that the no-tillage system, after 11 years of management, associated with nitrogen fertilization promotes positive PI and OP, being useful to farmers. KEY-WORDS: Zea mays; production cost; no-tillage; conventional tillage.

KEY-WORDS: Zea mays; production cost; no-tillage; conventional tillage.Práticas agronômicas que ajudem o agricultor a elevar a produtividade e diminuir os custos de produção devem ser estudadas para garantir a sustentabilidade agrícola. Assim, o objetivo deste trabalho foi analisar, economicamente, o efeito do manejo do solo e do nitrogênio, na cultura do milho. Os tratamentos foram constituídos pela combinação de 3 manejos do solo (grade pesada + grade niveladora, escarificador + grade niveladora e plantio direto) e 5 épocas de aplicação de nitrogênio (testemunha sem N; 120 kg ha-1 logo após a semeadura (S); 120 kg ha-1 no estádio V6; 30 kg ha-1 (S) + 90 kg ha-1 em V6; 30 kg ha-1 (S) + 45 kg ha-1 em V4 + 45 kg ha-1 em V8). Foram estimados o custo operacional total (COT), receita bruta (RB), lucro operacional (LO), índice de lucratividade (IL), produtividade de equilíbrio e preço de equilíbrio. Conclui-se que o sistema de plantio direto, após 11 anos de manejo, associado à adubação nitrogenada, promoveu LO e IL positivos, sendo favorável o uso destas práticas, pelos agricultores.
