Variety traits

Yield — Kale

Brassica oleracea L. (Kale Group)

The yield of kale is measured by the total mass of harvested leaves in tonnes per hectare over the growing season. The indicator directly depends on the strategy of multiple leaf mass harvesting.

In the reference 10 varieties crop Kale, where this is mentioned in the description.

Kale yield is calculated as the sum of the mass of all harvests throughout the growing season, as the crop does not form a head and allows for multiple cuttings. In variety trials, the methodology involves complete harvesting of produce from plots, followed by the weighing of each stage of leaf mass accumulation.

Modern hybrids in open-field conditions demonstrate a total yield in the range of 28.0 to 32.29 t/ha. When single cuttings are performed during the season, productivity indicators per harvest range from 4.05 to 5.63 t/ha. The final result is closely related to the intensity of leaf regeneration after harvesting.

The cultivation technology involves a "cut-and-come-again" strategy, in which only the outer leaves are removed, which stimulates further plant development. Unlike headed varieties, the yield of kale is determined by the continuous growth of vegetative mass, which depends on the genotype of the cultivar and nutritional conditions.
