Variety traits

Productivity of kale

Brassica oleracea L. (Curly kale Group)

A complex indicator defined as the total mass of marketable leaves per unit area, which depends on the variety's ability to regenerate leaf mass during multiple harvests.

In the reference 8 varieties crop Curly kale, where this is mentioned in the description.

In agronomic practice, the productivity of kale is measured in tons per hectare, and to assess the potential of varieties and hybrids, plant height, the number of leaves, and their average area are recorded. Under field trial conditions, the yield of this crop can vary within the range of 28.0–32.29 t/ha, depending on the cultivation technology.

The trait of productivity is closely linked to the method of multiple leaf harvesting, which accounts for the plant's ability to regenerate the leaf rosette after the outer leaves are removed. An important aspect is the balance between total mass and product quality, as leaf overgrowth leads to a decline in marketability, including the development of bitterness.
