High resistance to cancer, nematodes, mosaics and viruses. Medium resistance to late blight and leaf curl

The variety is not resistant to defeat by silver scab and rhizoctoniosis, therefore, it is mandatory to etch planting material.

Landing rules

Potato "Arosa" is suitable for growing on almost any type of soil, due to the high degree of adaptation of the variety.

Immediately before planting, preventive and stimulating treatment of tubers should be carried out against diseases to which this variety is unstable, for example, Fitosporin-M, Alirin-B or Gamair. It is desirable to use as effective growth regulators Cherkaz, Agate 25-K or "Mival", which enhance growth processes, accelerate ripening and increase overall productivity. When applying in spring, you can use both mineral and organic fertilizers:

  • one glass of ash + 1 tbsp. l superphosphate + 1 tsp potassium sulfate per square meter of planted area;
  • one glass of ash + 2 tbsp. l nitrofoski per square meter of landing area.

Medium-sized tubers are suitable for planting, you need to pay attention so that there are no spots, dents or deformations on the planting material.

At the landing sites represented by peat soils, it is desirable to introduce river sand, compost and high-quality humus. In the presence of clay soil, a bucket of humus or peat is added to each square meter. Sandy soils are improved by adding clay soil and peat or rotted humus.

Landing is carried out in a well-heated soil. The most comfortable potato feels at a temperature of + 9-10 ° C.

The standard landing pattern is 60x35 cm. When planting seed potatoes of the Arosa variety, it should be buried no more than 8-10 cm.

Care Features

Despite the fact that standard care for Arosa potatoes comes down to removing weeds, loosening the soil, hilling, watering, fertilizing and controlling diseases, as well as pests, high agricultural technology can stimulate a significant increase in yield. It is possible to reduce labor costs in the process of cultivating such an unpretentious cultivar as "Arosa" when using a ridge box or when growing potatoes according to Dutch technology or the Mitlider method.

In order to protect potato plantings from the Colorado potato beetle and potato ladybug, it is recommended to apply spraying during the growing season with an interval of 20-30 days “Fitoverm”, “Akarin”, “Bicol”, “Faskordom”, “Tsepellin” or Kinmiksom. Positive results were noted when spraying at the beginning of the budding phase of potato tops “Lurastim”, which increases the yield of marketable tubers and significantly increases yield indicators.

When cultivating Arosa potatoes, the fact that this the variety is characterized by responsiveness to the application of high doses of mineral fertilizers. With local application of mineral fertilizers, it is best to carry out the event in several stages, by feeding during the topping of tops.

This variety deserves positive reviews not only due to its excellent taste, but also due to its positive biological characteristics.

Agronomists praised the unpretentiousness of the variety and its indicators of adaptation to any adverse external factors, as well as the composition of the soil in the cultivation region. In addition, the variety stands out against the background of a large number of varietal novelties with a high level of resistance to the most basic and most harmful diseases for potatoes.
