Origin, history and botany: the ancient journey of the artichoke

La artichoke is native to the western Mediterranean basin, especially from regions including North Africa and Southern Europe. It was already consumed in ancient times by the Egyptians, Greeks, and Romans, who valued both its nutritional and medicinal properties. Greek mythology links it to the transformation of the nymph Cynara into this plant, and Historical documents attest to its cultivation and consumption in Rome and Greece..

During the Middle Ages, the Arabs spread artichoke cultivation throughout the Iberian Peninsula, where it became very popular, especially in regions such as Navarre (Tudela), La Rioja, Murcia, the Valencian Community, and Catalonia. It was also introduced to France and Italy, where highly recognized varieties were developed.

The artichoke belongs to the family of Asteraceae (composite), such as thistle or daisy. It is a perennial plant, although it is usually grown as a biennial or triennial in intensive production to ensure the best quality of the harvest. It reaches between 1,4 and 2 meters in height., with large, green, intensely segmented leaves, and produces fleshy inflorescences in the form of a head or chapter (the edible part before flowering).

Root system of the artichoke

La resistance and longevity of the artichoke This is largely due to its robust root system, anchored in a nutrient-storing rhizome. This characteristic allows it to survive periods of drought and adapt to different soil types, even in unfavorable conditions.

Flower and fruit

The artichoke's violet-blue flowers emerge in dense, fleshy terminal heads, wrapped in numerous bracts that protect the inflorescence. The fruit is a small, grayish achene that can retain its germination capacity for years.

Economic importance and dietary value

In Mediterranean countries, the Artichoke is a strategic vegetable in the agricultural economySpain, Italy, and France account for a large portion of the world's production, although it is also cultivated on other continents such as the Americas and Africa. In addition to fresh consumption, the food industry uses artichokes for preserves (hearts, bottoms, and pieces) and ready-to-eat preparations.

La artichoke stands out nutritionally due to its high content of water, fiber, inulin, minerals (potassium, magnesium, calcium, phosphorus, iron) and vitamins C, A, K, B1 and B9 (folic acid). This makes it a food low in calories and highly satiating, ideal for special diets.

Artichoke varieties: diversity and main types

There are dozens of commercial varieties of artichoke, which are grouped according to shape, color, early production, and area of ​​origin. The most famous are:

• Blanca from Tudela: a small, compact, light green Spanish variety. Very tender and appreciated fresh.
• Espinosa: Italian, with spiny bracts, well-suited for raw consumption. Fleshy and crunchy.
• Romanesco: Large, round, deep violet head. Very sweet, early-growing, typical of Italy.
• Violet of Provence: French, small and conical, violet in color. Can be eaten raw or cooked.
• Camus of Brittany: very large, spherical, green with purple hues. Highly prized in Western Europe.
• Green Globe: international variety, robust and productive.
• Imperial Star: obtained by seed, ideal for modern crops due to its resistance and high production.

In the world there are around 140 known varieties of artichoke, although only about 40 are grown commercially.

Ideal conditions for growing artichokes

Although the artichoke is rustic and adaptable, if optimal production is sought, attention must be paid to:

Climate

• The artichoke is a fresh cycle vegetable. It grows best in mild winters and cool springs.
• La optimal temperature varies between 7 and 29ºC. Intense cold can damage the plant, and extreme heat hardens the heads and reduces the harvest.
• Requires a vernalization period (cold exposure) to induce flowering, which prevents premature bolting.

Land

• Prefers soils deep, fertile, light and well-drainedWaterlogged soils promote root diseases.
• El pH ideal is between 7 and 8, with tolerance to slightly alkaline soils.
• Moderate resistance to salinity, although excess affects the quality of the heads and can cause necrosis in the bracts.
• Avoid heavy, clayey or compacted soils, which hinder root development.

Multiplication and propagation of the artichoke

The artichoke can be propagated in several ways, giving it versatility and adaptability to different cultivation systems:

By seed

• Currently there are hybrid varieties Suitable for direct sowing. This promotes genetic renewal and prevents the transmission of soil-borne diseases.
• Sowing takes place in spring in seedbeds. Seedlings are transplanted when they reach 5-10 cm in diameter.
• Varieties like Imperial Star o Green Globe are the most used in this system.

By suckers or clogs

• The traditional method consists of separating the side shoots that emerge at the base of the parent plant. Each sucker should have buds and some root.
• The best time is late winter or early spring, avoiding wet or excessively cold days.

By rhizome division

• It consists of dividing the rhizome into fragments, ensuring that each portion has at least one visible bud.
• Useful method for renewing adult plantations or when you want to expand the crop.

By rhizome cuttings

• Common in commercial farms, pieces of rhizome are cut and planted directly.

In vitro multiplication

• Virus- and disease-free plants are obtained, increasing production and health.

Land preparation and planting

Preparation of the land

• Make a deep tillage, especially in the first year, to promote root development and ensure good aeration.
• Eliminate weeds to avoid competition and pests.
• Incorporates mature organic fertilizer (manure, compost, worm humus) as base fertilizer, along with phosphorus and potassium according to soil analysis.

Sowing and planting

• Respect planting distances 80 to 120 cm between plants and 1-1,5 m between rows.
• Plant the root balls or cuttings in holes twice as deep as the shoot volume, covering them with compost and leaving the neck at ground level.
• Apply padded with straw, pruning remains or compost to conserve moisture and prevent weeds.

Irrigation in artichoke cultivation

El irrigation is essential To obtain tender and good-sized artichokes:

• Drip irrigation: It is the most efficient technique, since it provides water to the root area and minimizes the appearance of fungi.
• In traditional crops, sprinkler irrigation can be used, avoiding waterlogging.
• During the period of growth and fruit formation, watering should be frequent: every 2-3 days in summer, every 5-7 days in spring and autumn.
• In midsummer, restrict watering to induce dormancy and prevent plant exhaustion.
• Keep an eye on drainage and humidity, as excess water promotes disease.

Fertilization and fertilization

The artichoke demands soils rich in organic matter and a proper balance of nutrients:

• Bottom fertilization with compost or mature manure: provides nutrients and improves soil structure.
• Nitrogen: stimulates vegetative growth but in excess it generates soft chapters and a greater risk of diseases.
• Phosphorus: promotes flowering and root development.
• Potassium: improves the quality, size, texture and flavor of the chapters.
