crop Mangelwurzel,
where this is mentioned in the description.
The vegetation period is calculated from the appearance of mass seedlings to the attainment of technical maturity of the root crops. The duration of this process depends on the variety, regional climatic conditions, and agronomic practices, while exposure to long daylight hours can provoke undesirable bolting.
Maximum accumulation of the root crop's fresh mass occurs during the second phase of development — from canopy closure to row opening, which lasts about 60 days and requires maximum moisture availability. Excessive nitrogen nutrition in the second half of the vegetation period negatively affects nutrient accumulation, provoking excessive foliage growth to the detriment of the root crop.
