The varieties of the promising direction of the Ural Research Institute of the Russian Agricultural Academy include Irbitsky potatoes with an average ripening period: tubers are formed in 70-90 days. His date of birth dates back to 2009.
The Irbitsky variety is included in the State Register of the Russian Federation for cultivation in the Volgo-Vyatka and West Siberian districts. But thanks to its popularity, it "settled" in Ukraine and Moldova, where it is successfully cultivated to this day.
Description and characteristics
The Irbitsky variety is characterized by an average height of the bush, which is quite compact. It is a semi-erect plant with an intermediate growth pattern. The leaves are medium in size and wavy along the edge, rich, green in color.
The inner surface of the rim is painted in azure color. The skin of the tubers is pink-red, they are round in shape. Irbitsky's eyes are medium-sized, and the flesh is yellowish in color. One nest contains up to 6-8 tubers, each weighing 110-190 g. The pulp contains 13-16.5% starch.
One hectare yields 250-400 centners of starchy potato tubers. The variety is unpretentious: drought-resistant and slightly susceptible to damage, after which it quickly recovers. Possesses high resistance to many dangerous diseases that affect potatoes.
Advantages and disadvantages
Irbitsky potatoes can be assessed on a 5-point scale by 5 points: its advantages are undeniable, but it is quite difficult to identify the disadvantages.

Landing
If the planting material is of good quality and the planting dates are determined correctly, then a good harvest is guaranteed. Techniques for preparing tubers for planting are as follows:
- tubers are removed from the storage 3 weeks before planting in the ground;
- sort out potatoes, removing tubers unsuitable for planting;
- for germination, place in a warm place in the light;
- large tubers are cut so that each half has 3 eyes;
- they are treated with growth stimulants and drugs to protect against diseases.
An open, sunny place without drafts with any soil composition and soil acidity pH = 6 is assigned for planting. Naturally, the best harvest can be obtained on fertilized, fertile soils. The planting scheme is traditional: 60 × 35 cm to a depth of 10 cm in pre-dug furrows.
Planting should be as early as possible, but the soil temperature should correspond to + 7-8aboutC. In such conditions, potatoes quickly take root and grow. Planting time is usually mid-May. There are "two pitfalls" here: embedding tubers in cold soil leads to their rotting, and late planting with a delay of 2 weeks reduces the yield by 20%. Therefore, it is important to set the right timing for early nutritional production.

Care
The main approaches to the cultivation of Irbitsky potatoes are traditional and applicable, as for any potato crop. This is the loosening of the soil and the destruction of weeds. It is difficult to develop a universal scheme for the entire growing season, since much depends on climatic conditions. But since the Irbit potato is unpretentious, it withstands weather disasters and gives a good harvest in any conditions.
Hilling and feeding
Hilling is necessary for the growth of lateral underground shoots on which tubers develop. This is a necessary procedure for any kind of potato. Additional watering will not harm it, especially if the summer is hot and dry.
These agrotechnical measures are carried out in the following sequence:
- when the tops are growing, the first deep (by 10-12 cm) loosening is carried out, then 2 and 3 times the soil is loosened to a depth of 6-7 cm;
- when the potatoes reach a height of 15-17 cm, the bushes are ready for hilling, an earthen ridge is poured onto the plant by 18-20 cm;
- when the tops are closed, the Irbitsky variety needs the following (repeated) hilling;
- during the season, an average of three waterings are carried out, which are more convenient to combine with top dressing, especially on poor soils.
Fertilizers are applied even before the potatoes are planted, ash containing phosphorus and potassium, which are important for the development of the tuber, is introduced into the holes. And for its growth, nitrogen is needed: it is introduced in the form of ammophos or mullein.
In the course of growing Irbit potatoes, fertilizing is used:
- An aqueous infusion of 2 parts of droppings and 30 parts of water is prepared from chicken manure. First, you can prepare a concentrated infusion, and then (after 2 days) dilute it. Before fertilizing, the soil must be moist, otherwise the roots can be burned.
- The second feeding is carried out during the formation of buds. Use the same bird droppings or mullein in the same proportions. A liter of solution is used for the Irbitsky potato bush.
- During flowering, this potato variety can be fed with a dry composition consisting of ash (4 tablespoons) and potassium sulfate (1.5 tablespoons) per running meter.
In autumn, after harvesting 1 m2 square add a bucket of humus or compost, 15 g of potassium salt and 30 g of superphosphate.
Diseases and pests
Irbitsky potatoes practically do not get sick with common potato infections. If diseased bushes nevertheless appear, then insecticide treatment is needed.
With a small number of pests on potatoes (for example, the appearance of the Colorado potato beetle, potato moth or wireworm), treatment with folk remedies is possible that will not harm the soil and other inhabitants of the backyard.
Harvesting
Irbitsky potatoes are harvested in August, since this is a mid-season variety:
- For 1-2 weeks, the tops are mowed to ripen the tubers.
- Harvesting is carried out in dry weather, laying out the tubers under a canopy.
- Small, diseased or damaged tubers are discarded.
- They are laid in a pre-prepared storage for the winter.
Small tubers are not suitable for this, they will adapt for a long time and will slowly grow when planted.
