Resumo: From 1986 to 1995, in Passo Fundo, RS, Brazil, the effects of soil tillage systems and crop rotationwere assessed. Four soil tillage systems 1) no-tillage, 2) minimum tillage, 3) conventional tillage using disk plow,and 4) conventional tillage using moldboard plow and three crop rotation systems [system I (wheat/soybean),system II (wheat/soybean and common vetch/corn or sorghum), and system III (wheat/soybean, black oats orwhite oats/soybean, and common vetch/corn or sorghum)] were compared. An experimental design of blocks atrandom with split-plots and three replications was used. The main plot was formed by the soil tillage systems, whilethe split-plots consisted of the crop rotation systems. Energy conversion (energy produced/energy consumed)and balance (energy produced - energy consumed) during a tem-year period is presented in this paper. For energyconversion and balance, no-tillage (6.38 e 16,252 Mcal/ha) and minimum tillage (6.53 e 16,434 Mcal/ha) presentedthe higher rates, while conventional tillage using disk plow remained in an intermediate position (6.27 e 17,578Mcal/ha) and tillage using moldboard showed the lowest rate (6.06 e 14,987 Mcal/ha), respectively. The croprotation for wheat was more efficient in energy than the monoculture of this cereal. Corn presented the higherefficient in energy.

O delineamento experimental foi em blocos ao acaso, com parcelas subdivididas e três repetições. A parcela principal foi constituída pelos sistemas de manejo de solo, e as subparcelas, pelos sistemas de rotação de culturas. Neste trabalho, apresentam-se a conversão energética (energia produzida/energia consumida) e o balanço energético (energia produzida - energia consumida) no período de 10 anos. Para conversão e balanço energético, o plantio direto (6,38 e 16.252 Mcal/ha) e o cultivo mínimo (6,53 e 16.434 Mcal/ha) apresentaram os maiores índices, enquanto o preparo convencional de solo com arado de discos situou-se em posição intermediária (6,27 e 17.578 Mcal/ha) e o preparo convencional de solo com arado de aivecas teve o menor índice (6,06 e 14.987 Mcal/ha), respectivamente. A rotação de culturas para trigo foi mais eficiente energeticamente do que a monocultura desse cereal. O milho apresentou maior eficiência energética.
