- good product performance, almost 97%;
- high taste;
- keeping quality of the harvest is not lower than 96%;
- resistance to pathogens of potato cancer, wrinkled and banded mosaics, to the leaf curling virus, is practically not affected by the golden potato cyst-forming nematode.

Potato "Irbitsky": harvesting
Dates and features of landing
It should be remembered that as a result of planting potatoes in unheated soil, tubers can partially die and rot, and seedlings will appear only after a month and a half. Deviations of planting of this vegetable crop from the optimal timing even by 1.5-2 weeks reduce the yield of potatoes by about 20-22%. Potatoes of the Irbitsky variety are recommended to be planted in central Russia no earlier than mid-May.
About three weeks before planting, potatoes should be prepared for planting, namely:
- sort out tubers, removing rotten or diseased; place potatoes in a warm and bright room for germination and landscaping;
- divide planting material by size into fractions;
- Cut too large tubers (each part should have at least 2-3 eyes);
- treat planting material with protective preparations and nutrient solutions.
Potato tubers should be planted in prepared furrows. The soil must be fertilized with mineral and organic substances. Planting scheme for potato tubers 60 x 35 cm at a depth of 8-10 cm.
The main care for potatoes at the vegetation stage is to maintain the soil in the most friable state and to conduct systematic destruction of weeds. Simultaneously with loosening, potatoes need to be spudded, that is, sprinkle the earth with a hill to the stem.
Dry and too hot days in the summer often alternate with very cool and humid ones, which makes it almost impossible to develop a universal care regimen. However, hilling, cultivation, weeding, top dressing and infrequent irrigation are still the main agrotechnical measures for the care of potatoes:
- the first loosening should be deep, 10-12 cm, and the second and third should be no more than 6-7 cm;
- at a plant height of 15-17 cm, the first hilling is carried out (the height of the soil ridge is 18-20 cm);
- the second hilling of potatoes is carried out before closing the tops;
- watering is desirable to combine with top dressing with organic and mineral fertilizers. In total, no more than three such events are required per season.
