Resumo

This study analyzes the implementation costs of four models of integrated Crop-Livestock systems, with corn in tillage (Zea mays L.) intercropped with Brachiaria decumbens, without conventional tillage in the first year and subsequent years, while comparing them with two others grazing models used to rear Nellore females during the agricultural years of 2007-08, 2008-09 and 2009-10. This economic study was based on the technical coefficients matrices constructed from data gathered from an experiment on Crop-Livestock Integration (CLI) developed at the Unidade de Pesquisa e Desenvolvimento de São José do Rio Preto (SP), no Pólo Centro Norte. In this experiment, four models of rotational grazing with Brachiaria decumbens x corn in comparison to permanent pasture of Brachiaria decumbens fertilized with two levels of nitrogen fertilizers (45 and 90 kg/ha/year), with and without correction of soil acidity, respectively. The four integration models differ by the occupation of the areas during the rainy season, with the following combinations: one or two consecutive years of corn intercropped with brachiaria, followed by one or two years of grazing. During the dry season, all areas are used as pasture. The economic results were grouped into four categories with similar characteristics in terms of area occupation and management, regardless of treatment, considering the averages: P- per
