Desempeño de implementos de labranza en términos de consumo de energía y calidad de trabajo

Performance evaluation of four tillage implements in terms of energy consumption and work quality. The evaluation of technological performance of multiplough, vibrocultivator, (vertical tillage) compared to disc plough and discs harrow (local conventional system), was carried out looking at the quality of work and energy consumption of these implements when tilling the soil. The experiment was established in a clay soil, using a random blocks statistical design a with six treatments and three replications. Assessing the performance of the configuration tractor - implement, it was found that the vibrocultivator and the disc harrow had the biggest capacity, less fuel consumption per worked area, as well as less power requirement, so these treatments are statistically different to those of disc plough and multiplough. When looking at the quality and energy required for operation of the imple- ments it was determined that the disc harrow treatment has a significant difference with that of har- rowing after plough, and that the multiplough produced the biggest aggregates and the vibrocultivator the smallest ones. The energetic index and the unit strength from the treatments of disc plough and multiplough have a significant difference with all the others, the energetic index and unit strength from the disc plough was higher in a 32 % and 25.5 % respectively compared with the figures from the multiplough. The geometry, cutting intensity, and soil manipulation influence the difference of the unit strength among implements.
