Several decades ago, yellow-fleshed potatoes were fed to farm animals. Its taste was not up to par. At the end of the 70s of the twentieth century, German breeders made a splash with the creation of Adrett's potatoes with yellow flesh and a pleasant taste. It was this quality that determined the growth of the variety's popularity, which it has not lost until now.

The botanical description of the variety is presented in the table.

Agricultural technology varieties

The Adretta variety is unpretentious in care, it endures drought and a sharp cold snap. The culture is planted on loose sandy loam and loamy soils. In peat soil add 200-300 kg of sand per 100 m², and heavy loam is lightened with humus (500 kg per 100 m²). When planting, preference is given to open, well-lit areas.

Potatoes need regular watering, loosening, weeding, hilling, mineral fertilizing, preventive spraying against pests and diseases.

Timing, scheme and landing rules

Potatoes are planted in the last decade of April - mid-May. For 20-25 days, the tubers are taken out of the cellar to a warm, bright place for germination. The seeds are pre-soaked in the Epin growth stimulator, and then kept for 20–30 minutes in a slightly pink solution of potassium permanganate, Fitosporin or copper sulfate.

The plot is prepared for planting in the fall - it is dug up and fertilized with humus. In the spring, they re-loosen and form holes 8–10 cm deep with an interval of 35–40 cm. The row spacing is 50–60 cm.

Put 1 tbsp in each hole. l. mullein and superphosphate. Tubers are divided into parts so that each of them has 1–2 eyes. This ensures high yields.Sprinkle the cut with wood ash and lay the material with seedlings up. Next, the holes are covered with earth and the beds are leveled with a rake.

Care

Adretta potatoes cope with drought, but do not tolerate stagnant water in the ground. The bushes are watered from a watering can as needed, after the topsoil has dried. Consumption per plant - 3-4 liters. Sprinkler irrigation is carried out in dry, hot weather.

The beds are loosened after each watering to prevent the formation of a hard earth crust.

Hilling potato bushes is a mandatory procedure, contributing to the preservation of moisture, saturation of the soil with oxygen, the formation of tubers. Hilling is carried out twice during the growing season: the first - when the bushes reach 8-10 cm in height, the second - 20 cm. Moisten the soil before the procedure. All manipulations are carried out in the morning or in the evening due to the negative effects of the sun on the bushes.

When feeding Adrett's potatoes, nitrogen fertilizers are applied carefully. In the case of this variety, a deficit is better than an overabundance, otherwise the plant will begin to actively gain vegetative mass, and the tubers will grow small.

Potato bushes are fed depending on their appearance:

1. Thin and weak shoots, lethargic leaves indicate a lack of minerals. For feeding, use 15 g of urea / 10 l of water or an infusion of chicken manure (500 ml / 10 l). Consumption per plant - 500 ml.
2. During the budding period, a second portion is introduced (3 tbsp. L ash, 1 tbsp. Potassium sulfate per 10 l of water). Consumption per bush - 500 ml.
3. The third additional portion of fertilizers is applied at the height of flowering to stimulate tuberization (100 g superphosphate / 10 l or 2 g sodium humate / 10 l). The solution is used for spraying plantings.

The nuances of growing and possible difficulties

Another method is used to grow potatoes: planting in grass without digging the soil. On a selected area with grass, rows are marked using stakes and a rope. The distance between the rows is 50-60 cm. Every 20-30 cm, 2-3 tubers are laid out in a checkerboard pattern. Cover with hay or straw on top with a layer of 30 cm.

During the growing season, cut grass is poured onto the beds, constantly renewing the mulch layer. The slop that is poured between the rows serves as fertilizer.

Diseases and pests

Adretta's potatoes are susceptible to late blight of tubers and foliage, common scab and rhizoctonia. The table contains information about the signs of diseases and methods of treatment.

Fungicides help to fight the Colorado potato beetle:

• Fitoverm;
• "Prestige";
• "Aktara";
• Corado;
• "Taboo";
• "Killer";
• "There is NO Colorado potato beetle!"

Traditional methods:

• dusting with corn flour in the morning, on leaves damp with dew for better adhesion;
• Leave 1 kg of green fruits or walnut leaves / 10 liters of hot water for 7 days, strain before use;
• 100 g of dry roots of elecampane / 5 liters of hot water, leave for 3 hours and spray the bushes;
• 0.5 kg of sunflower flowers pour 10 liters of water and leave for 3 days;
• 1.5 kg of celandine / 10 liters of boiling water, leave for 3 hours, add 1 liter of a solution of 1.5% calcium chloride.

Cicadas, the main carriers of fungal diseases, feed on potato foliage. To destroy the pest, birds are attracted to the site, and the bushes are treated with Prestige, Tabu, Akarin, Calypso, Decis preparations.

Collection, storage and use of the crop

Harvesting is carried out in a timely manner - from late August to mid-September, as ripe tubers begin to rot in moist soil. The renewal of seed material is carried out in 3-5 years.

The collected tubers are laid out in a dark room to dry for 3-4 days, then they are laid out in wooden, plastic boxes, linen bags. The optimum air temperature in the room is +2 ° С, humidity is 80–85%.

Council. To prevent the potatoes from sprouting, place some apples in the crates.

On a balcony or loggia, potatoes are stored in boxes, which are installed on supports so that they do not come into contact with the ice floor, or in thermal containers (large backpacks powered by the mains).

The tubers are regularly examined and sorted out, completely removed from storage. Rotten and green fruits are thrown away.

Adretta's potatoes taste good. A characteristic feature - as a result of freezing, it does not acquire a sweetish taste. The product is suitable for boiling, frying, roasting and stewing. Due to the high starch content, the tubers quickly fall apart in water, so they are steamed to preserve their structure.

Advantages and disadvantages

The advantages of Adrett potatoes include:

• fast growth of green mass;
• early maturation;
• excellent taste;
• when freezing, the pulp does not become sweet and does not change color;
• resistance to viruses and cancer;
• unpretentious care.

Among the disadvantages:

• in drought, with a lack of moisture, tubers stop growing;

Farmers reviews

For several decades of its existence, the Adretta variety has won the love of farmers and consumers, thanks to its guaranteed high yield, pleasant taste and ease of care.

Pavel, Nizhny Lomov: “The German variety Adretta has been considered one of the best for many years. I have been growing it on my site for a long time and every time they get an excellent result. The tubers after cooking are soft, slightly crumbly, tasty, even if they freeze in winter, they do not become sweet.

Nina, Kolyvan: “We have been growing potatoes in the hay for five years in a row. For us, this is the easiest and most effective way. There is no need to dig the ground, and then even huddle. Plants do not get sick, Coloradas do not gnaw them. The Adretta variety, as always, is on top. The tubers are smooth, with yellow skin and pulp. "

Oksana, Komsomolsk-on-Amur: “Everyone seems to know this German fruitful variety. Many people grow it in our region, including me. Potatoes have a pleasant taste, do not degenerate for a long time, but they are not resistant to late blight, black and common scab. I advise you to buy seeds from trusted producers, so you can be sure of the quality of the material and get the expected result. "

Conclusion

Adretta's potatoes have not lost their leadership position for several decades in a row, since its inception. Smooth yellow tubers have a pleasant taste, are stored for a long time in a cool place, do not freeze and are suitable for frying, boiling, stewing and baking.

The culture has a strong immunity to cancer and viruses, but is unstable to late blight, black and common scab. Preventive measures (crop rotation, seed treatment in potassium permanganate or copper sulfate, timely harvesting and the introduction of potassium-phosphorus fertilizers) help prevent or at least minimize the likelihood of infection.
