| Combine harvesting is one of the most energy consuming field operations in arable farming. The power demand of combine harvester depends strongly on the mass flow through the machine, and one approach to reduce the energy consumption is thus increasing the stubble height in harvesting. In this study, the energy saving possibilities by increased stubble height and different straw management in cereal harvesting were examined. In addition to combine harvesting, the mulching of the tall stubble with a tractor powered rotary mower after the harvest was investigated. The results indicated an energy saving of 22%–24% in combine harvesting of spring wheat “Quarna” when the stubble height was increased from 13 cm to 35 cm, and 17% with 13 cm stubble when the... |
