Title : Impact of the crop technology on the index value of mechanical damage to potato tuber
Key words : potato, harvesting technologies, damage to pulp, loading a storage
Summary :

The objective of the paper was to show whether there are differences in the level of mechanical damage of potato tubers collected in different technologies. The level of damage was estimated on every stage of potato harvesting in each technology. The scope of the paper covered research of the damage size on particular stages of harvesting and loading potatoes to the storage (5 measuring points: a separating belt of a combine, a trailer, a charging hopper, a separating belt of a sorter, a heap) in the 1-stage harvesting technology with the use of GRIMME SE-170 combine (fig. 1) and two options of 2-stage harvesting with the use of 4-row digger Grimme RL-3600 and Grimme GT-170 or Grimme GZ - 1700 combine (fig. 2). The size of damage was expressed with the index of bruises of tubers referred to 1 kg. The obtained results proved that at the 1-stage harvesting, higher values of the damage index were reported on the stage of loading the combine tank, trailers and a heap in the storage in comparison to 2-stage harvesting. From among two harvesting technologies of 2-stage harvesting, higher values of damage were reported for technology that used Grimme GT-170 combine, mainly at the stage of loading the combine tank.
