Jerusalem artichoke (Tuberous sunflower of the Astrov family) - in common people better known as "earthen pear". It is a ubiquitous, unpretentious plant that has edible tubers that are rich in nutrients. Both the tubers themselves and the green part are used for food. Also, the plant is used as livestock feed, used in medicine and pharmaceuticals.

There are many varieties of Jerusalem artichoke that differ in appearance, yield, size of tubers, amount of green mass and other indicators.

How not to make a mistake when choosing?

The approach to choosing a variety of Jerusalem artichoke depends on the purpose. Varieties with a predominant growth of the upper part of the plant are fodder varieties, and varieties with a predominant development of tubers are tuber varieties with a wide range of applications.

According to the ripening period, Jerusalem artichoke varieties are:

  • early;
  • medium;
  • late.

In their properties, they can also vary greatly (read about the medicinal properties of Jerusalem artichoke here, and from this article you will learn how the vegetable root is useful). Based on this, it is important to choose the right variety of Jerusalem artichoke for its cultivation, it must meet the needs of farmers. That is, it is important here which part of the plant will be needed, tubers or greens. Otherwise, the resulting product will not meet the demand that the manufacturer expected.

The second thing to consider when choosing a variety is the ripening period, that is, the period from planting to harvesting must be sufficient for a given climatic zone, otherwise it may not have time to give a good full harvest.

It should also take into account the fact that late varieties will slightly extend the shelf life of the tubers. And the green mass should be in large quantities throughout the season, so varieties of all ripening periods will be needed so as not to be left without feed in the middle of summer.

If Jerusalem artichoke is grown for decorative purposes or to protect other plants from the winds, then varieties with good decorative properties and increased deciduous mass are needed, which guarantees maximum effect.

Selection rules in different climatic zones

Not every variety is suitable for every region, as different regions have completely different climatic conditions.

  1. For the Urals.

    It is important to choose earlier varieties, since the development cycle of this variety must have time to pass completely before the onset of winter. It is also worth stopping the choice on frost-resistant varieties that allow you to grow Jerusalem artichoke even in the northernmost latitudes, in which tubers can be left in the soil for the whole winter without digging, and which are preserved until spring by 90-100%. With the help of selection, many hybrids with desired properties have been bred.

  2. For central Russia.

    For warm regions of the middle zone of the country, it is advisable to take into account the presence of increased requirements for the variety for heat and drought. It is also recommended to choose late-ripening varieties - these are mainly tall (up to 3-4 m), giving a lot of greenery (up to 1000 c / ha), and tubers, albeit smaller ones.

  3. For Siberia.

    In Siberia, it is not so easy to find a suitable variety of Jerusalem artichoke. Early ripening varieties take root best here. Of course, they can be grown in all regions, but they are especially relevant in this region. Early ripening varieties can also remain in the soil until spring without any loss of properties.
