Is it possible to save potatoes, and how to select the right tubers for long-term storage?


Potatoes are a strategically important crop and a staple food.

This valuable product is used to produce molasses, starch, alcohol and even rubber in the chemical industry. In addition, potatoes are used in animal husbandry as feed.

Consider various technologies and storage conditions for a vegetable, namely, the correct processing of potatoes, ambient temperature, shelf life and possible diseases.

What are the varieties of potatoes. Can peeled potatoes be stored? In what conditions can the seed tubers of a vegetable be stored?

Can this vegetable be stored?

Can I store harvested or purchased potatoes? Potatoes can not only be stored, but must also be stored. This is especially true for seed potatoes, which are then planned to be sown and grown. It is extremely important to preserve such a root crop without deteriorating its varietal qualities.

The hardest time to save potatoes is in the spring before planting. At this time of the year, the tubers wilt and germinate very quickly. Therefore, it is extremely important to observe the storage conditions, sort the potatoes and protect them from light.

How to save: technology and conditions

How to pre-process correctly?

Before you send to store potatoes for a long winter time, they must first be properly processed. After picking potatoes must be dried.

When drying tubers in the sun, do not leave them longer than a few hours, otherwise the potatoes will turn green.

After drying, the roots need to be sorted out, because damaged, green or rotten potatoes are not suitable for long-term preservation. Choose medium sized tubers that are flawless and well dried.

You cannot send the vegetable to dry in a dark, unventilated room, because the vegetable generates a lot of heat.

Temperature

For long-term preservation of potatoes, a temperature of about two to four degrees is recommended. In this case, the humidity in the room should be about 80%. Reduce the temperature in the potato storage room gradually and avoid minus temperatures. At negative temperatures, the potatoes become sweet, freeze, and at temperatures above four degrees, the tubers can germinate.

Timing

If we talk about the terms of saving potatoes, then it varies depending on the conditions in which they are stored. But if we talk about average values, then at a temperature not exceeding five degrees Celsius, tubers are stored for about six months... You can also store this vegetable in the refrigerator. In this case, the storage period is one month. If you put the root vegetable in the freezer, then it can lie for up to 9 months.

Tuber diseases

With proper care, potatoes will last for a long time. But there are a number of tuber diseases that can appear during storage:

  1. Ring rot - a bacterial disease affecting tubers. Several soft, rounded, cream-colored spots appear on the root crop.
  2. Dry rot - disease of damaged tubers at elevated temperatures in storage.
  3. Blackleg - a bacterial disease in which the pulp of the tuber decomposes with the release of mucus.
  4. Scab - fungal disease with lesions of the skin of the root crop. Infection occurs in the soil.
  5. Wet rot - a bacterial disease transmitted from tuber to tuber. The pulp decomposes and takes on an unpleasant odor. It develops at elevated temperatures in the storage area (read about the storage locations for potatoes here).

To combat these diseases, it is enough to carefully handle the potatoes, sort out the tubers during storage and observe the temperature regime for storing the potatoes.

Why problems can arise when storing potatoes and how to deal with them, it is said here.

Varieties

Best of all and the late-ripening vegetable is stored much longer than other varieties... Root crops of these varieties are saturated with useful microelements, but for preservation it is better to choose two or three varieties so that the tubers survive until spring with less "losses".

The best varieties of potatoes for storage are recognized:

  • Picasso.
  • Zhuravlinka.
  • Blue.
  • Asterix.
  • Atlant.
  • Lorch.
  • Vesnyanka.

When choosing potatoes for aging, consider factors such as late ripening, healthy fruit without damage, and growth in loose soil. In addition, the potatoes must be fully ripe.

Rules for a peeled vegetable

It should be remembered that the rules for storing peeled potatoes are very different from storing simple potatoes. The fact is that peeled vegetable quickly darkens and becomes covered with a dry crust... But in water, the tubers perfectly retain their properties and appearance. At the same time, it is not necessary to cut the root vegetable into pieces, it is best to leave the fruits whole and cut them just before cooking.

REMEMBER! Peeled potatoes, even in water, cannot be stored for more than a few hours.

Wintering conditions for seed tubers

In addition to eating, gardeners often store potatoes for later planting. Before storing a vegetable for sowing, you need to choose ripe and completely healthy tubers... If the roots are not yet fully ripe, they should be placed under a canopy for 12 days to ripen and dried in the fresh air.

The saving conditions for seed potatoes do not differ from those for ordinary tubers - two to four degrees of heat, with a gradual decrease by one degree per day and an increase several weeks before planting.

We talked in detail about storing potatoes in winter in our material.

With the correct maintenance of potatoes, waste can be almost completely avoided. At the same time, the vegetable retains all its taste and nutritional value until spring.
