Nom de la culture: Cabbage
La description: Cabbage (Brassica oleracea var. Capitata) originates from the south and the western coast of Europe. Annual world production is about 55 million tons of fresh heads from 2.6 million ha (FAOSTAT, 2001). For high production the crop requires a cool, humid climate. The length of the total growing period varies between 90 and 200 days, depending on climate, variety and planting date, but for good production the growing period is about 120 to 140 days. Optimum growth occurs at a mean daily temperature of about 17°C with daily mean maximum of 24°C and minimum of 10°C. The fertilizer requirements are high: 100 to 150 kg/ha N, 50 to 65 kg/ha P and 100 to 130 kg/ha K. Cabbage is moderately sensitive to soil salinity. Yield decrease due to soil salinity at different levels of ECe is: 0% at ECe 1.8, 10% at 2.8, 25% at 4.4, 50% at 7.0 and 100% at ECe 12.0 mmhos/cm. Generally, the heavier loam soils are more suited to cabbage production. Under high rainfall conditions, sandy or sandy loam soils are preferable because of improved drainage. Row spacing is dependent on the size of heads required for markets or between 0.3 and 0.5 m for heads of 1 to 1.5 kg each and 0.5 and 0.9 m for heads up to 3 kg each. An optimum production can be reached with a plant density in the range of 30000 to 40000 plants/ha. In Ghana, it can be grown anywhere, however, commercial production is done in Southern Ghana particularly Akwapim and Kwahu areas.
