Every vegetable grower dreams of growing potatoes on their plot that ripen very early. Arosa makes it possible to enjoy young root vegetables as early as June. The variety is valued for its high yield, drought resistance and unpretentiousness. This is especially important for busy summer residents who, due to circumstances, cannot provide the plant with proper care.
Origin story
The Arosa potato variety got its start in Germany. German breeders bred it in 2009. The originator of the new variety is Uniplanta Saatzucht KG. In 2000, the variety was officially included in the Russian state register. Potatoes began to be actively imported into the country, sold and propagated.
Arosa is suitable for cultivation in the Ural, Caucasus, and Middle Volga regions of the Russian Federation and in Siberia. German potatoes are also popular in Ukraine and Moldova.
Description
Potato Arosa is a universal, early-ripening variety characterized by high yield. On average, 70-75 days pass from emergence to harvest. The first digging can be done after 55-60 days after landing.
The potato bush is compact, medium in size, with semi-erect stems. The plant is strewn with small green leaves. The inflorescences are lilac, with a reddish tint.Shoots are uniform.
Arosa tubers have a round, slightly elongated shape. The peel is dark pink with a reddish tint. The surface is smooth, with a slight roughness in places. There are small eyes on the surface of the potato. The pulp is dark yellow, It crumbles when cooked. Potatoes have excellent taste and commercial qualities.
The mass of the tuber is within from 70 to 135 grams. On average, you get 15 potatoes from a bush. With proper care, one hectare of plantings can yield 50-70 tons of crops. The root vegetable contains about 12-15% starch. This variety is great for making chips and French fries.
Advantages and disadvantages
Arosa has many positive characteristics:
- rapid ripening;
- high productivity;
- excellent taste (4.6 points out of 5);
- Tolerates drought well, which is why this potato variety can be grown without additional artificial irrigation;
- excellent presentation of tubers;
- resistant to nematode, virus U, mosaic and cancer;
- does not lose its taste and external qualities during storage and transportation;
- uniform shoots.
Potatoes of this variety have much fewer disadvantages than advantages. Arosa can be affected by rhizoctonia, silver scab and late blight. Therefore, before sowing, it is necessary to treat the planting material. Bushes can also be attacked by the Colorado potato beetle.
Landing
Arosa is usually planted in May. The earth should warm up to +9-10 degrees. For planting, choose a sunny area with a flat surface. The best predecessors of potatoes are legumes, cabbage, onions, cucumbers and winter rye.This variety is unpretentious, so it can be grown in any soil.
In the fall, the following organic and mineral fertilizers are applied to the selected area (per 1 m2):
- superphosphate – 1 tbsp. l.;
- potassium sulfate – 1 tsp;
- ash – 1 cup;
- humus or compost - 1 bucket.
If the soil is clayey, river sand is added to it. Fertilizers are evenly scattered over the surface of the site and the soil is dug to a depth of 20-25 cm. In the spring, the soil is harrowed again, leveled with a rake and weeds are removed. The procedure saturates the soil with oxygen.
Two weeks before planting, the root crop is taken out of the cellar. Tubers are sorted, damaged and diseased ones are thrown away. The weight of seed potatoes should be between 60-75 grams. The more eyes it has, the better. To germinate, the tubers are placed in a bright room, where the air temperature is maintained at a level of +12 to +15 degrees. When the sprouts reach 3-4 cm, the potatoes are planted.
To prevent diseases, before planting, Arosa tubers are sprayed with Fitosporin, Alirin or a solution of copper sulfate. To increase yield and accelerate the ripening of potatoes, they are treated with growth regulators. Some of the most effective stimulants are Agat 25-K and Cherkaz.
In order for the harvest to be of high quality, each bush must have sufficient feeding area. Arosa tubers planted to a depth of 8-10 cm with an interval of 35-40 cm. Leave at least 70-75 cm of free space between the rows. According to the planting scheme, holes or trenches are dug. Potatoes are planted with sprouts up and sprinkled with soil to a depth of 5-6 cm.
Care
Caring for potatoes of this variety is easy.The area needs to be cleaned regularly weed, as well as loosen, irrigate and fertilize the soil. The ripening period of the crop and the volume of the harvest depend on the quality of care.
Watering and loosening
It is recommended to water Arosa throughout the entire growing season. at least three times. The first irrigation is carried out a month after planting, the second - during the formation of buds, the third - after flowering. In hot and dry weather, the plant is watered more often. Each potato bush should receive at least 3 liters of warm water. Moistening the area is carried out in the evening or before sunrise.
To saturate the soil with oxygen and retain moisture, the soil is regularly loosened. The procedure is carried out after watering, when the soil dries out a little. Loosening helps get rid of weeds.
Hilling
Hilling is the process of filling the lower part of the bush with moist soil. After the procedure, the potato roots begin to grow intensively and branch, so more tubers are formed.
During the entire growing season, potatoes of the Arosa variety are hilled 3 times:
- When the height of the shoots reaches 8-10 cm. If frost is expected, the plant must be completely covered with earth.
- During the period of bud formation.
- During flowering. The height of the comb should be about 18-20 cm.
If the bushes stretch out and fall apart, it is recommended to carry out unscheduled hilling. The procedure is performed carefully so as not to damage the tubers.
Top dressing
Feeding of potatoes of this variety is carried out in several stages. It is important to strictly observe the proportions, since Excess fertilizer can destroy the plant.
During the period of formation and growth of tubers (during budding and flowering), mineral and complex fertilizers with a high content of potassium and phosphorus are added to the soil. To prepare the nutritional composition, you need to mix 15 g of potassium sulfate and 15 g of superphosphate. The mixture is dissolved in 10 liters of water and watered over the potato plantings. Consumption – 1 liter of solution per 1 m22.
20 days before digging up the tubers, Arosa bushes are watered with complex mineral-organic fertilizer. To do this, 0.25 liters of manure and 20 g of superphosphate are dissolved in a bucket of water. Thanks to this feeding, root crops will receive a supply of nutrients necessary for long-term storage.
Diseases and pests
Arosa is characterized by high resistance to mosaic, nematode, Alternaria, Fusarium, potato blight and viral infections. This potato variety susceptible to infection with rhizoctonia, silver scab, late blight tops and tubers.
The photo shows a tuber affected by silver scab.
From the table you can find out how each of these diseases manifests itself and how to deal with them.
Disease | Signs of infection | Control measures |
Late blight | Brown spots form on the leaves, then a gray coating appears. The bush begins to dry out. | Spraying with Kurzat, Ridomil or Acrobat. At the first signs of disease, potatoes can be treated with Fitosporin. |
Silver scab | Brown spots are found on the tubers, which over time acquire a silver tint. The peel dries and wrinkles. | After harvesting, the potatoes are sprayed with the agrochemical Maxim. And before planting, they are treated with Celeste Top or Quadris. |
Rhizoctoniosis (black scab) | Dark spots appear on the tubers, looking like pieces of dirt.They rot during storage. Brown spots and sores form on sprouts and roots. | Seed potatoes are sprayed with the agrochemical Maxim, and before planting they are treated with Tecto, TMTD or Titusim. |
To prevent diseases, you need to observe crop rotation, plant healthy seeds and timely harvest.
From pests Arozu can attack the Colorado potato beetle and mole cricket. They get rid of them with the help of drugs such as Bicola, Fascorda and Kinmiks.
Harvesting
The peculiarity of this variety is that 15 days before harvesting, mow the potato tops. This reduces the likelihood of the plant becoming infected with late blight. At the same time, stop watering.
For food, potatoes can be dug up in late June - early July, when the plant begins to bloom. Harvesting is completed at the end of July. The tubers are thoroughly dried, sorted and placed in boxes with small holes. The root crop is stored at a temperature from +2 to +4 degrees.
Conclusion
