Cabbage comes to harvest in 80-180 days from seed and in 60 -105 days from transplants.
Cabbage seeds ½ inch deep, spaced 1 inch apart; thin plants to 18 to 24 inches apart.
Space seedlings 18-20 inches apart in rows 24-32 inches apart.

Crop Management 
Consistent and even watering leads to high yield and if they’re starved of water it will result in stunted growth and cracked heads.
Cabbage can be inter-cropped with onions,potatoes,strawberries and tomatoes.
Farmers can apply  Nitrogen fertilizer to prevent split heads and twist heads.
