Abstract
Searching for production alternatives for small farmers, Goyaz Group -Teaching, Research and Extension has been working with Serra Abaixo Small Farmers Association (APASA), in Inhumas, Goias State. Data were collected through questionnaires during the corn ( Zea mays L.) crop growing period, in the farmer areas, making up 33,370 m2, from August 8 to October 18, 1996, under animal traction no-tillage. The objectives were to determine operational costs, gross income, manpower and capital utilization indexes, and to develop the economic-financial analysis of the green corn crop under farm conditions. All participating farmers achieved positive financial results as expressed by gross margin, which varied individually from R$319.89 to R$1,760.67, while the average gross margin was R$ 901.02. Under the experimental conditions the most adequate period to plant animal traction no-tillage corn is August, secondarily extended through mid September. KEY-WORDS: Gross margin; animal traction no-tillage; operational costs.
