Crohn's potatoes are a promising proposal from German breeders. The variety is unpretentious, takes root in any climatic conditions and pleases with its yield. Large juicy potatoes are perfect for preparing first and second courses. Grow it as if it were personal useand for sale.

Description of the variety

Crohn's potatoes are a mid-early table variety. Its yield is from 430 kg / ha, vegetables are stored for a long time and contain a small amount of starch - up to 12%. The variety is unpretentious in care, it tolerates short-term drought well. It can grow without fertilizers, but feeding will not hurt to collect large and high-quality tubers.

On a note... Potatoes contain about 80% water, they are rich in vitamins and minerals. It also contains a lot of provitamin A, which is necessary to support vision.

Origin and development

Crohn's (Krone) variety was bred by the German breeding company Bavaria-Saat GBR. This agro-technical enterprise has been developing and multiplying new varieties since 1987. The company has released about 15 varieties of potatoes that can satisfy the highest consumer demands.

Since Crohn's potatoes are distinguished by increased resistance to temperature extremes and lack of moisture, they are actively cultivated in many regions of our country.

Distinctive features

The main indicators of this variety:

• the size of vegetables is average, weight is about 100-130 g;
• the shape of the potato is oval, with a smooth top;
• tubers are neat, aligned in weight and size;
• the shell is yellow, uniform, thin and smooth;
• eyes are superficial, small;
• the pulp is yellow;
• the starch content does not exceed 12%;
• high content of fiber, protein, carotene and vitamins.

Description and characteristics of the plant and crop

Plants of this variety are slightly spreading, erect stems. The root system is well developed, fibrous. Small leaves are dark green in color. The inflorescence consists of white flowers, while the seeds are not formed at the end of flowering - this is another feature of the variety.

Crohn's potatoes are not reborn - varietal qualities are preserved, transferred from the parent planting material to the next generation. Under each bush, from 10 to 15 tubers are formed, there are practically no small ones.

Yield

Crohn's variety belongs to the medium early - vegetables ripen 100 days after landing... The yield is high, depending on climatic conditions, vegetable growers harvest from 430 to 650 c / ha.

Interesting... In total, there are about 4 thousand varieties of potatoes in the world.

How to grow this variety

Although the variety is unpretentious, competent care will only benefit it. Compliance with all the rules and recommendations is the key to a rich harvest.

Timing, scheme and landing rules

The best precursors for potatoes are carrots, cabbage, legumes and green manures... In the area where the nightshade was grown, there is a risk of common diseases.

The best soil for planting is black soil and sandy loam. In the fall, before plowing, organic fertilizers are applied to the ground. If it is not possible to do this before winter, in the spring, add rotted cow dung, peat or ash directly to the holes - in this case, frequent feeding will not be needed.

2-3 weeks before planting, the seed is germinated: placed in a bright, warm room, pre-treated with a growth stimulator, for example, "Epin". One ampoule (0.25 ml) of the drug is diluted in 400 ml of water and the tubers are sprayed. One ampoule is enough for spraying 200 tubers.

For planting, choose a healthy medium-sized seed. When the air temperature stays at + 10 ° C, they are buried in the ground.

Landing scheme:

• a distance of at least 30 cm is left between the plants;
• the width between the rows is about 60-70 cm;
• the seeds are deepened by 5-8 cm.

On a note. The most suitable planting method for the Crown is planting on the ridges.

Care

To protect plants from sudden frosts, retain moisture during drought and shelter from the sun's rays, hilling bushes are carried out. For the entire growing season, the event is performed twice:

• the first time upon reaching the sprouts 15-18 cm;
• the second time 20 days after the first.

Crohn's potatoes are resistant to short-term drought, but during bud formation they need moderate irrigation. Due to lack of moisture, small tubers are formed. For the entire growing season, plants are irrigated 2-3 times. Watered at the root, as the ingress of water on the foliage will increase the risk of late blight.

Soil aeration is the key to strong culture immunity. The event promotes the formation of a strong root system and the ripening of large potatoes. The aisles are loosened after each wetting of the plants so that the soil does not crust over. For the entire period of culture growth, at least 2-3 loosening is carried out.

Also, the soil is eliminated from weeds. Weeding begins even before the emergence of shoots. The site is cleared of weeds at the time of hilling, as well as as needed.

Crohn's potatoes do not need frequent feeding. It responds well to mineral phosphorus-potassium fertilizers, for example, "Potassium Monophosphate", "Agrofoska" or "Ecoplant". Organic matter is introduced at planting.

Council. To reduce the growth of tops on the site, exclude the introduction of nitrogen-containing fertilizers.

The nuances of growing and possible difficulties, diseases and pests

In hot weather, to preserve moisture in the soil, mulching the beds is done. For this, straw, grass or peat bedding is used. Another such shelter is used to protect landings from sudden cold weather.

Cultivation of Krona is practically no different from the cultivation of other varieties. Difficulties can only bring possible diseases or pest attacks.

Common potato scab is a fairly common disease. Affected tubers retain their presentation for a much shorter period, their taste deteriorates. The disease appears in dry seasons, when there is not enough moisture in the soil heated to +25 ... + 27 ° C with a pH level below 5.5. The disease mainly affects tubers; it spreads to stolons and roots less often. If the culture is sick with scab, use the drug "Mancozeb" (1.2-1.6 kg of funds per hectare of planting, dissolved in water and sprayed).

Golden nematode is one of the most common and dangerous potato diseases. Tubers are either not formed at all, or are underdeveloped. The plants themselves lag behind significantly in development. The cause of the disease is small worms - nematodes, the size of which barely reaches 1 mm. Young spherical females are white. Over time, the color turns yellow, gradually turning into brown tones. The golden nematode is destroyed with Fitoverm. The product is used in dry or hot weather.

The most common pests:

1. Aphid. These are small insects, the length of which reaches 3.5 mm. Among them there are individuals with and without wings. The pest is ubiquitous. Potato aphids are disposed of with insecticides such as Force, Thunder 2 or Regent.
2. Colorado beetle Is a representative of the leaf beetle family. The pest has an oval body 8-15 mm long and about 7 mm wide.The larvae are colored orange with black spots. The body of an adult insect is covered with rigid elytra with black and yellow stripes. The Colorado potato beetle is dealt with by spraying the area with Marshal, Sumicidin or Colorado preparations.
3. Medvedka Is a large insect (up to 8 cm) that digs holes in the ground and feeds on potatoes. It belongs to the Orthoptera family and is capable of flying over short distances. Medvedka is destroyed by treating the plantings with Medvetsid or Medvetox. Some summer residents use the means of "Regent" or "Fenaskin +".
4. Cicadas - these are pests of medium size (1-3 cm), which are similar to jumping butterflies. During the day, insects hide in anthills, and at night they crawl out to the surface and drink plant sap. Affected potato bushes are treated with insecticides such as "Akarin", "Vizcaya", "Calypso" or "Proteus".

Collection, storage and use of the crop

Seven days before harvesting, all tops are cut off. This allows vegetables to gain essential nutrients and increases their nutritional value. After a week, the potatoes are dug up with a shovel or walk-behind tractor.

The harvested tubers are dried in the sun (no more than 2 hours), sorted and stored in a room with an air temperature of about + 5 ... + 10 ° C and a humidity of no more than 90%. The harvest is stored in wooden boxes, bags, nets in the cellar or basement.

The tubers are placed in boxes with small holes. The layer should not exceed 0.5 m so that the lower vegetables are saturated with oxygen, and excess moisture evaporates. Containers with crops are placed on pallets or planks at a short distance from the walls.

Every month, the condition of the potatoes is checked and spoiled tubers are removed so that rotting does not spread to other vegetables. The room is regularly ventilated. The shelf life of this grade is 96% if there is no condensation in the storage area.

Crohn's potatoes are good for making French fries, baking, frying and even freezing vegetable mixes. When cooking potatoes remain intact, so they are used to make salads. Heat treatment only enhances the taste and aroma of vegetables.

Attention! If the potatoes have turned green, then it is better not to eat them. In such vegetables, under prolonged exposure to sunlight, a poisonous substance is produced - solanine.
