Every vegetable grower dreams of growing potatoes on his plot, which ripens very early. Arosa makes it possible to enjoy a young root crop already in 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.
History of origin
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 state register of Our Country. Potatoes began to be actively imported into the country, sold and propagated.
Arosa is suitable for cultivation in the Ural, Caucasian, Middle Volga regions of the Federation and in Siberia. German potatoes are also popular in Ukraine and Moldova.
Description
Arosa potato is a versatile, early-ripening variety that is characterized by high yields. From germination to harvest, an average of 70-75 days pass. 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. Inflorescences lilac, with a reddish tint. Shoots are uniform.
Arosa tubers have a rounded, slightly elongated shape. The skin is dark pink with a reddish tint. The surface is smooth, in some places there is a slight roughness. Small eyes are located on the surface of the potato. The flesh is dark yellow, crumbles when cooked. Potatoes have excellent taste and commercial qualities.
The weight of the tuber is within from 70 to 135 grams. On average, 15 potatoes are obtained from a bush. With proper care, 50-70 tons of crops can be harvested from one hectare of plantings. The root contains about 12-15% starch. This variety is excellent for making chips and french fries.
Advantages and disadvantages
Arosa has many positive characteristics:
- fast maturation;
- high yield;
- excellent taste (4,6 points out of 5);
- tolerates drought well, so this potato variety can be grown without additional artificial irrigation;
- excellent presentation of tubers;
- resistant to nematode, virus Y, mosaic and cancer;
- does not lose its taste and external qualities during storage and transportation;
- uniform shoots.
The disadvantages of this variety of potatoes are much less than the advantages. Arosa can be affected by rhizoctoniosis, silver scab and late blight. Therefore, before sowing, it is necessary to treat the planting material. Also, the bushes can attack 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.
Since autumn, the following organic and mineral fertilizers have been applied to the selected area (based on 1 m2):
- superphosphate – 1 tbsp .;
- potassium sulfate – 1 tsp;
- ash – 1 glass;
- 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 up 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 are thrown out. The mass of seed potatoes should be in the range of 60-75 grams. The more eyes it has, the better. For germination, the tubers are cleaned in a bright room, the air temperature in which is maintained at a level of +12 to +15 degrees. When the sprouts stretch up to 3-4 cm, the potatoes are planted.
For the prevention of diseases, before planting, Aroza tubers are sprayed with Fitosporin, Alirin or a solution of copper sulphate. To increase the yield and speed up the ripening of potatoes, they are treated with growth regulators. Some of the most effective stimulants are Agate 25-K and Cherkaz.
In order for the harvest to be of high quality, each bush must have a sufficient feeding area. Arosa tubers planted to a depth of 8-10 cm with an interval of 35-40 cm. Between the rows leave at least 70-75 cm of free space. According to the planting scheme, holes or trenches are dug. Potatoes are planted with sprouts up and sprinkled with soil by 5-6 cm.
Care
Caring for potatoes of this variety is easy. It is necessary to regularly clean the site of weeds, as well as loosen, irrigate and fertilize the soil. The maturity of the crop and the volume of the crop depend on the quality of care.
Watering and loosening
For the entire growing season, Arosa is recommended to be watered 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. Humidification of the site is carried out in the evening or before sunrise.
To saturate the soil with oxygen and preserve moisture, the soil is regularly loosened. The procedure is carried out after watering, when the soil dries out a little. Loosening helps to get rid of weeds.
Hilling
Hilling is the process of backfilling the lower part of the bush with wet earth. After the procedure, the roots of the potato begin to grow and branch intensively, so more tubers are formed.
For the entire growing season, potatoes of the Aroza variety are spud 3 times:
- When the height of the shoots reaches 8-10 cm. If frosts are expected, then 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 and fall apart, it is recommended to carry out an unscheduled hilling. The procedure is performed carefully so as not to damage the tubers.
Additional fertilizing
Top dressing of potatoes of this variety is carried out in several stages. It is important to strictly observe the proportions, since too much fertilizer can kill the plant.
During the formation and growth of tubers (during budding and flowering), mineral and complex top dressings with a high content of potassium and phosphorus are introduced into 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 potato plantings are watered. Consumption – 1 liter of solution per 1 m2.
20 days before digging up the tubers, Aroza bushes are watered with a 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 top dressing, 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 cancer and viral infections. This type of potato prone to infection with rhizoctoniosis, silver scab, late blight tops and tubers.

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 |
Fitoftoroz | Brown-brown spots form on the leaves, then a gray coating appears. The bush starts to dry up. | Spraying with Kurzat, Ridomil or Acrobat. At the first signs of illness, potatoes can be treated with Fitosporin. |
silver scab | On the tubers, spots of brown color are found, which eventually acquire a silver tint. The peel dries and shrinks. | After harvesting, the potatoes are sprayed with Maxim agrochemical. And before planting, they are treated with Celeste Top or Quadris. |
Rhizoctonia (black scab) | Dark spots appear on the tubers, similar to pieces of dirt. During storage, they rot. Brown spots and ulcers form on sprouts and roots. | Seed potatoes are sprayed with Maxim agrochemical, and before planting they are treated with Tecto, TMTD or Titusim. |
To prevent diseases, it is necessary to observe crop rotation, plant healthy seed material and carry out timely harvesting.
From the pests of Arosu can attack the Colorado potato beetle and bear. They get rid of them with the help of drugs such as Bicola, Faskorda and Kinmiks.
Harvesting
The peculiarity of this variety is that 15 days before harvesting, the tops of potatoes are mowed. This reduces the likelihood of plant infection with late blight. At the same time stop watering.
For food, potatoes can be dug up already in the last days of June – early July, when the plant will fade. Harvesting culture is completed at the end of July. The tubers are carefully dried, sorted and laid out in boxes with small holes. The root crop is stored at a temperature of +2 to +4 degrees.
Conclusion
Arosa attracts attention with her ruggedness and versatility. This German potato variety is considered one of the best. It is resistant to many common diseases. Therefore, Arosa can be safely grown on your site without worrying about the safety of the tubers.
