Does root tip breakage caused by the harvester sufficiently predict sugar losses during beet storage? [Full subscriber]

Abstract In Europe, campaign lengths have increased to up to 120 days necessitating a longer sugar beet (Beta vulgaris L.) storage period post-harvest. Sugar beet harvest is performed by 6-row self-propelled harvesters. Depending on the harvester setting (cleaning turbine rotational speed, harvester driving speed), harvest can cause considerable injuries to the beet taproot, thereby causing mass and sugar losses during storage. The proportion of the cleaning unit, when adjusted to an efficient reduction of soil tare, on injuries in relation to damages exerted by other harvester sections has not yet been quantified. Further, knowledge is lacking regarding the quantitative relationship…
