Cabbage is a cool season crop.
Cabbage (Brassica oleracea var capitata) is a small, leafy biennial producing a compact globular mass of smooth or crinkled leaves wrapped over each other known as head.
In India, cabbage is grown in large areas having a cool and moist climate. A temperature range of 15° - 21°C is considered optimum for the growth and head formation of the crop. The intensity of flowering depends upon the age of the plants and the period for which they are exposed to low temperatures.
