The plant height of root chicory is defined as the distance from the soil surface to the tip of the longest rosette leaf. This parameter characterizes the vigor of the leaf apparatus, which determines inulin accumulation and the potential productivity of the root crops.

where this is mentioned in the description.
During variety trials, measurements are taken on random samples of plants in experimental plots. During the rosette growth stage, plant height varies from 30 to 75 cm, while flowering shoots in the second year of life can reach 120–150 cm. Variety descriptions more frequently use a qualitative assessment of height, as there are no rigid classifiers for this trait.
This trait is positively correlated with root yield, reflecting the development of the assimilation apparatus. Excessive development of the above-ground part, often caused by an excess of nitrogen nutrition, can lead to a decrease in root productivity. Rosette height is also taken into account when evaluating the convenience of mechanized maintenance in inter-row spacing.
