OPERATIONAL PERFORMANCE IN THE SAFELY CORN SOWING IN THE DIRECT SOWING SYSTEM

Abstract

The sowing of maize is subject to factors that may affect the quality of the operation, especially climatic factors that directly affect the soybean harvest and consequently the corn sowing, so it is necessary that both operations are efficient, ensuring the success of agricultural production. Faced with the above, aimed to evaluate the operating performance in sowing winter corn in Fazenda Chopim  in Novo Mundo - MT in the year 2017. Evaluations were carried out of the operating performances in three days of sowing in two areas of trapezoidal and irregular shape with gently sloping topography, collecting production times, breaks and preparation, as well as distance. The data collected in the field and recorded on data sheets were launched in worksheets in Excel, and with the help of the program was given operational performance. For the conduction of the test, the tractor BH180, brand Valtra, 2008 and Tatu Marchesan sowing machine, Model Ultra Flex, with 28 lines, were used to compose the sowing tractor combination (only this set). We evaluated the theoretical field capacity, effective and operational and operational efficiency. The operational performance of the entire farm Chopim had a mean effective field capacity equal to the theoretical field capacity (12 ha h^-1). Sowing in Fazenda Chopim was considered efficient because showed values (65,66%) within the range considered efficient in literature (50-75%).
