Cabbage (Brassica oleracea var. capitata) is one of the most widely cultivated vegetables in Kenya. It is highly nutritious, being a rich source of Calcium, Iron, Vitamin A, Vitamin E, Minerals, Riboflavin, Vitamin B3 (Niacin) and Vitamin C (Ascorbic Acid). Cabbage is grown primarily in the cool highland regions, where the climate is ideal for its growth. Smallholder farmers are key players in cabbage production, and the crop provides both food security and income opportunities. In Kenya, cabbage growing is done on a small scale and also large scale farming. Sustainable cabbage farming practices are essential to maintain high yields while addressing challenges such as pests, diseases, and market fluctuations.
