Cabbage crops
The cabbage (Brassica oleracea var. Capitata L or var. Sabauda L), the cauliflower (Brassica oleracea var Botrytis L), Brussels sprouts or Brussel Sprout, English (Brassica oleracea var gemifera L), cabbage broccoli (Brassica oleracea var Italica L) and kohlrabi, Kolrhabi, in English, (Brassica oleracea var gongylodes L) are biennial plants, originating in Northern Europe and belonging to the cruciferous family. The part consumed is the apple for cabbage (sheets stacked on top of each other petioles + reduced), the inflorescence for the cauliflower and broccoli, basal bulge in the stem for the kohlrabi and axillary buds for the Brussels sprouts. The nutritional value of cabbage is very high. Sprouts are rich in Vitamins C, carotene, minerals, sugars and proteins. The wide variety of sprouts is the source of its many names (Beijing cabbage, Chinese cabbage, Savoy cabbage, red cabbage in addition to the names already mentioned). In Morocco, sprouts are well known and grown in all regions. Low flow capabilities of the products is the cause of small areas reserved for farming culture.
Soil and climatic requirements:
All sprouts have the same ecological requirements (see Broccoli cabbage). The plant is cold season, very rustic and very resistant to cold and snow for over two weeks.
Varieties, sowing, planting, tillage and other cultivation operations:
For the cabbage, the known varieties are F1 Head Star, Pacifica, Discovery, Charming, Pirimero, Red Rookie Express, Nantais hasty, Balacan. Examples of varieties of red cabbages, head: hatif Red, Dark Red Erfurt. Examples of varieties of cabbage Milan: Early Position of Saint John, Virtues, Aubervillier. Examples of varieties of cauliflower: Rolls snow, Nain Erfurt, Giant Danish, Norman, late Naples Giant. Examples of kohlrabi varieties: White hatif Vienna, Violet hasty Vienna. Examples of varieties of Brussels sprouts: Dwarf Lyon, Half Dwarf Hall, Jade Cross. The work of soil and plant crops is done in the same manner as those of cabbage broccoli. All other cultivation operations are the same as those carried on Cabbage Broccoli.
Harvest:
The harvest is manual. More harvest is early, the lesser are the organs to be harvested (apples for cabbage or inflorescences for broccoli sprouts and cauliflower or swelling at the base of the shaft for the kohlrabi or magnification axillary buds for cabbage Brussels). The yield of early crops does not exceed 15-20 t / ha. That of late crops (harvested organs well completed) exceeds 60-70 T / ha for cabbage and 30 t / ha for cauliflower and kohlrabi. Brussels cabbage gives nearly 4-10 tons / ha in the best conditions. The inflorescences of cauliflower must be protected against high temperatures by the outer leaves of cabbage, otherwise they lose their quality (white, dense flowers). If the harvest is late, harvested parts become fibrous and lose quality.
