Variety traits
Brassica oleracea L. (Kale Group)
The maturity group of kale is determined by the number of days from mass emergence to the moment leaves reach marketable size. This classification is used for harvesting schedules and accounts for the rate of leaf biomass accumulation.
In the reference 8 varieties crop Kale, where this is mentioned in the description.
Early-maturing kale varieties are ready for harvest 55–70 days after emergence, mid-season varieties in 70–85 days, and late-maturing varieties require 80 days or more. Since this crop does not form a head, the ripening process is associated with the plant reaching a specific vegetative mass suitable for selective or once-over harvesting.
The maturity trait determines the cultivation technology: early varieties are optimal for production during the spring-summer period. Late-maturing varieties are characterized by increased cold tolerance and are more often grown in the autumn, as exposure to low temperatures after reaching technical maturity improves the flavor of the leaves.
