Data set for a method of non-destructive determination of the fresh sugar beet mass between emergence and harvest

Up to now, it has not been possible to determine the beet biomass of sugar beet non-destructive dynamically during the growth process. This value is important for the parameterisation of crop growth models. Studies on individual beets show that there is a close relationship between the beet diameter at the widest (thickest) point and the beet biomass. To quantify this relationship data were colleced. The data set contains four sugar beet varieties from the 1990s for three different locations (Müncheberg, Hohenfinow and Dedelow) in Brandenburg, Germany. The data set contains more than 6,700 data records. The measurements were realized in approx. 14-day intervals between rising and harvesting. Different cultivation systems (intensive, organic, extensive) were taken into account additionaly with and without use of irrigation.
