摘要

> size="2" face="Verdana">Reduction in sowing period and intensification of production in no-tillage system, promoted an increase in the frequency of the use of machines and implements, causing compaction of soil due to traffic. The compaction, in addition to affecting the development of plant roots, increases the power demand of the implements, justifying the use of chisel plows for soil decompactation. The performance of two chisel plows (Shank + tip), one commercial and one experimental, was evaluated to understand the chiseling (scarification) operation adapted to no-tillage system and compare two chisel plows, using as parameters such as energy and soil variables. The experimental decompactation element performed better in comparison to commercial, in key variables, such as fuel consumption, power and traction force. When installed ahead of descompactation elements the cutting disc did not alter the traction force and reduced the fuel consumption and power. The increase in the speed provided an increase in traction force, power and fuel consumption.
