Turnip

The turnip (Brassica rapa subsp. rapa) is a plant in the Brassicaceae family, which also includes cabbage, broccoli, radish and mustard. It is cultivated mainly for its swollen underground storage organ, commonly called the root, although it develops from both the upper part of the root and the lower part of the stem. Depending on the variety, it can be round, flattened, oval or elongated, with skin that may be white, cream, yellow, green or purple. The flesh is usually white or pale yellow.

Turnips are cool-season crops and can tolerate light frost, which is why they are often grown in spring or autumn in temperate regions. Their leaves form a rosette above the soil and can also be eaten. If the plant is left to mature, it produces small yellow flowers arranged in clusters, followed by narrow seed pods. Like other members of the cabbage family, the turnip contains natural sulfur compounds called glucosinolates, which contribute to its characteristic sharp taste.

In the kitchen, young turnips can be eaten raw, while mature ones are often cooked in soups, stews, purées or roasted dishes. The leaves can be prepared like other leafy greens and are a source of vitamins, minerals and fiber. The underground part contains plenty of water and provides dietary fiber, vitamin C and several B vitamins, while its energy content is relatively low. The flavor becomes milder when the turnip is cooked, and younger roots are generally more tender than older ones.

For cultivation, turnips prefer a cool climate, sufficient sunlight and loose, fertile soil that allows the swollen organ to develop evenly. Regular watering helps prevent excessive toughness and irregular growth. Seeds are usually sown directly into the soil, and harvesting can begin only a few weeks later for some early varieties. If left in the ground too long, turnips may become larger, tougher and more strongly flavored.
