dc.description.abstract | 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 V 6 stage; 30 kg ha -1 (S) + 90 kg ha -1 in V 6; 30 kg ha -1 (S) + 45 kg ha -1 in V 4 + 45 kg ha -1 in V 8 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. | |
