Rentabilidade Do Plantio Direto De Grãos Em Unidades Familiares No Norte Do Paraná, Brasil
AbstractO presente artigo avaliou a rentabilidade do conjunto de lavouras de grãos sob plantio direto, utilizando a análise multicaso de treze estabelecimentos agropecuários familiares de grãos no Norte do Paraná, Brasil, através da avaliação das margens brutas por hectare-ano ao longo de seis safras anuais entre 1998/99 e 2003/04. Averiguou-se ainda a existência ou não de uma relação entre a rentabilidade e os diferentes tipos de plantio direto com respeito ao nível de revolvimento do solo, à realização de rotação de culturas e ao acesso a maquinários apropriados.---------------------------------------------This article evaluated the profitability of the mix of grain crops under no-tillage, in a multiple case analysis of thirteen family enterprises of grains in the North of Parana State, Brazil, through evaluation of gross margins per hectare-year by six annual seasons between 1998/99 and 2003/04.
