Botanical and biological features

The red cabbage (Brassica oleracea var. capitata f. rubra), along with the white cabbage, comprises a single botanical species, their patterns of development being almost identical.

The leaves of red cabbage are intense red-purple in color. The red cabbage is considerably superior to the white cabbage in carbohydrate, protein and vitamin content. It is used for salads, as well as for making marinades and borsch (soup made of beetroot and cabbage).

Growing tips

The best preceding crops are annual legumes, cucurbits, winter cereals, early tomato and potato, and onion.

The main growing technique in red cabbage cultivation is transplanting. The transplants should be 25–45 days old, depending on the growing technique, and have 3–6 well-developed leaves. The planting pattern is 70 х 30 cm. The seeding rate is 50–90 seeds per 10 m2 of open ground. Cassette or potted transplants become established more readily since no root system injuries occur during transplanting and, consequently, there are no diseased plants.

During the growing season, fertilizers are applied at a rate of N 240, P2О5 120, K2О 240 kg of active substance per hectare. 50% of the amount of fertilizer is applied with basic soil preparation as nitroammophoska at a rate of 750 g per 10 m2, the remainder being given as supplementary fertilizing with ammonium nitrate and potassium nitrate at a rate of 250 g per 10 m2. The fertilizer application rates are adjusted according to the nutrient status of the soil.

Systematic irrigation is a crucial factor in the cultivation cycle. During the growing season, 8 to 12 irrigations are given to the crop with a water application rate of 350–400 l per 10 m2 (350–400 m3/ha) per irrigation prior to the formation of heads and 400–450 l per 10 m2 (400–450 m3/ha) after the formation. Combining drip irrigation with application of water-soluble fertilizers through the drip irrigation system (fertigation) is a highly efficient technique resulting in a more uniform moisture and fertilizer distribution in the root zone, more efficient water use, less soil compaction, and no soil crust formed. Readily soluble mineral fertilizers are given with each water application.

During the growing season, numerous pests such as blue fleas, cabbage aphid, cabbage butterfly and cutworm, cabbage moth, and thrips may attack the crop. Therefore, chemical control is an essential component of the red cabbage production technology.
