Consumo de combustível de um trator agrícola na semeadura do milho (Zea mays L.) em diferentes sistemas.

Abstract

Among the costs of production of a certain culture the expense with fuels and lubricants and to reduce factor as the tratory effort imposed to the plans inside of a sowing system in matter, can be modified. The present work had for objective to evaluate the consumption of fuel of a tractor to traction an seeder with different pressures of tire inflation during the implantation of the culture of the corn under the system no tillage and conventional tillage. The experiment was accomplished in the area of the Laboratório de Maquinas e Mecanização Agrícola (LAMMA), of the Departamento de Engenharia Rural, FCAV/UNESP, Jaboticabal, SP, with randomized blocks design in factorial array of 2x3, originating 6 treatments with 4 replications, totaling 24 observations.Were measured and analyzed the fuel consumptions: volumetric, ponderal, for area and specific. In the conventional system of sowing was observed the smallest fuel consumptions: volumetric, ponderal and for area. The inflation pressures of the tires of the seeder used in the rehearsal didn't interfere in the fuel consumption in the no tillage system. In the smallest inflation pressure used the smallest consumptions were observed for the conventional system of sowing.
