Resumo: The objective of this study was to evaluate the profitability of maize, soybean and wheat crops under different soil tillage systems. The experiment, covering twelve cultivations, was carried out at 'Embrapa Arroz e Feijão' (Santo Antônio de Goiás, GO, Brazil), on Oxisol, under center pivot irrigation for six consecutive years (from September 1992 to September 1998). The tillage treatments were: moldboard plough, harrow disc, and no-tillage. Soybean and maize were sown in November-December and wheat in May-June. The moldboard plough tillage system showed the highest benefit/cost operational ratio (2.03) for the maize crop: 4.6% and 3.1% higher than harrow disc and no-tillage systems, respectively, with a net profit of R$749.02/ha. The harrow disc tillage system showed the highest benefit/cost operational ratio for the soybean and wheat crops (1.22 and 1.31, respectively): 5.2% and 2.5% higher than the moldboard plough and 3.5% and 9.2% higher than the no-tillage system. Under the harrow disc tillage system, the net profit was R$157.03/ha for soybean and R$272.27/ha for wheat.KEY-WORDS: Moldboard plough; harrow disc; no-tillage; economical evaluation.

O objetivo deste trabalho foi avaliar a rentabilidade do milho, da soja e do trigo em diferentes sistemas de preparo do solo. O experimento foi conduzido em Latossolo Vermelho perférrico, em área irrigada por pivô central, na Embrapa Arroz e Feijão, em Santo Antonio de Goiás, GO, durante seis anos, de setembro de 1992 a setembro de 1998, nos quais foram feitos doze cultivos. Foram comparados três sistemas de preparo do solo: aração com arado de aiveca, aração com grade aradora e plantio direto. As culturas do milho e da soja foram semeadas em novembro-dezembro, e a do trigo foi semeada em maio-junho. Para a cultura do milho, o sistema de preparo do solo que propiciou maior relação benefício/custo operacional (2,03) foi aquele em que se utilizou arado de aiveca. O sistema representou 4,6% e 3,1% a mais em relação à grade aradora e ao plantio direto, respectivamente, gerando uma receita líquida de R$749,02/ha. Para as culturas da soja e do trigo, o sistema de preparo do solo que apresentou maior relação benefício/custo operacional foi o da grade aradora, 1,22 e 1,31, respectivamente. Isso representou 5,2% e 2,5% a mais em relação ao arado de aiveca e 3,5% e 9,2% em relação ao plantio direto. Com o uso desse sistema, a receita líquida foi de R$157,03/ha para a soja e de R$272,27/ha para o trigo.
