Artichoke - Agricultural Output

Agricultural Output

Today, globe artichoke cultivation is concentrated in the countries bordering the Mediterranean basin. The main European producers are Italy, Spain, and France. In the United States, California provides nearly 100% of the U.S. crop, and about 80% of that is grown in Monterey County; there, Castroville proclaims itself to be "The Artichoke Center of the World", and holds an annual artichoke festival. Most recently, artichokes have been grown in South Africa in a small town called Parys located along the Vaal River. According to FAO, the top 10 artichoke producing countries are :

1. Italy 486,600
2. Spain 198,900
3. Egypt 180,000
4. Peru 144,317
5. Argentina 90,293
6. China 67,000
7. Morocco 64,610
8. United States of America 50,710
9. France 46,752
10. Chile 44,600
11. South Africa 30,000

Artichokes can be produced from seeds or from vegetative means such as division, root cuttings or micropropagation. Though technically perennials that normally produce the edible flower only during the second and subsequent years, certain varieties of artichoke can be grown from seed as annuals, producing a limited harvest at the end of the first growing season, even in regions where the plants are not normally winter-hardy. This means home gardeners in northern regions can attempt to produce a crop without the need to overwinter plants with special treatment or protection. The recently introduced seed cultivar 'Imperial Star' has been bred to produce in the first year without such measures. An even newer cultivar, 'Northern Star', is said to be able to overwinter in more northerly climates, and readily survives subzero temperatures.

Commercial culture is limited to warm areas in USDA hardiness zone 7 and above. It requires good soil, regular watering and feeding, plus frost protection in winter. Rooted suckers can be planted each year, so mature specimens can be disposed of after a few years, as each individual plant lives only a few years. The peak season for artichoke harvesting is the spring, but they can continue to be harvested throughout the summer, with another peak period in midautumn.

When harvested, they are cut from the plant so as to leave an inch or two of stem. Artichokes possess good keeping qualities, frequently remaining quite fresh for two weeks or longer under average retail conditions.

Apart from food use, the globe artichoke is also an attractive plant for its bright floral display, sometimes grown in herbaceous borders for its bold foliage and large purple flower heads.
