Abstract

The objective of the study was to evaluate the power demand and energy consumption in three tillage systems and two tractor working gears. The experiment was conducted in the Agronomy-Airport experimental area of the Universidade Federal de Viçosa, located in Viçosa-MG, Brazil. Three land tillage systems were introduced: conventional, minimum and direct in a subdivided plots experimental design with two tractor working gears and four replications, totaling 24 experimental plots. The fuel consumption per hour and hectare, power and traction power and consumed energy in MJ ha-1, in each mechanized operation were determined; processing of the results using an analysis of variance in the software Statistics SPSS 21 showed that the working gear had a signifi cant impact on the obtained values for the traction power, the fuel consumption and the energy consumption in the three tillage systems, where higher values were obtained when using the B2 gear. The fuel consumption per hour and per hectare, and the energy consumption (MJ ha-1) signifi cantly differed in the three tillage systems, being lowest for the direct tillage system, higher for minimum tillage and the highest value was acquired for the conventional tillage system. The conventional tillage system was the largest consumer of energy.
