Among the promising varieties of the Ural Research Institute of the Russian Agricultural Academy is the Irbitsky potato 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 Volga-Vyatka and West Siberian districts. But thanks to its popularity, it was “located” 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 habit. The leaves are medium in size and wavy along the edges, rich green in color.
The inner surface of the corolla is painted azure. The skin of the tubers is pink-red, they are round in shape. The eyes of Irbitsky 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 a yield of 250-400 centners of starchy potato tubers. The variety is unpretentious: drought-resistant and little susceptible to damage, after which it quickly recovers.It is highly resistant to many dangerous diseases that affect potatoes.
Advantages and disadvantages
Potatoes of the Irbitsky variety can be rated out of 5 on a 5-point scale: its advantages are undeniable, but its disadvantages are quite difficult to identify.

Landing
If the planting material is of good quality and the planting dates are determined correctly, then a good harvest is guaranteed. The techniques for preparing tubers for planting are as follows:
- tubers are removed from storage 3 weeks before planting in the ground;
- sort through the 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.
For planting, an open, sunny place without drafts with any soil composition and soil acidity pH = 6 is allocated. Naturally, the best harvest can be obtained on fertilized, fertile soils. The planting pattern is traditional: 60x35 cm to a depth of 10 cm in pre-dug furrows.
Planting should be as early as possible, but the soil temperature should be +7-8OWITH.In such conditions, potatoes quickly take root and grow. Typically, planting time is mid-May. There are “two pitfalls” here: planting tubers in unheated soil leads to their rotting, and late planting with a delay of 2 weeks reduces the yield by 20%. Therefore, it is important to correctly determine the timing for obtaining early nutritional products.

Care
The main approaches to cultivating the Irbitsky potato variety are traditional and applicable, as for any potato crop. This is loosening the soil and destroying weeds. It is difficult to develop a universal scheme for the entire growing season, since much depends on climatic conditions. But since Irbitsky potatoes are unpretentious, they can withstand weather disasters and produce a good harvest in any conditions.
Hilling and fertilizing
Hilling is necessary for the growth of lateral underground shoots on which tubers develop. This is a necessary procedure for any potato variety. Additional watering will not harm it, especially if the summer is hot and dry.
These agrotechnical activities are carried out in the following sequence:
- when the tops grow, the first deep (10-12 cm) loosening is carried out, then the soil is loosened 2 and 3 times 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 of 18-20 cm is poured onto the plant;
- when the tops are closed, the Irbitsky variety needs the following (repeated) hilling;
- On average, three waterings are carried out per season, which are more convenient to combine with fertilizing, especially on poor soils.
Fertilizers are applied even before potatoes are planted; ash containing phosphorus and potassium, which are important for the development of the tuber, is added to the holes. And nitrogen is necessary for its growth: it is added in the form of ammophos or mullein.
When growing Irbitsky potatoes, the following fertilizers are used:
- An aqueous infusion is prepared from chicken manure from 2 parts of manure and 30 parts of water. First, you can prepare a concentrated infusion, and then (after 2 days) dilute it. Before fertilizing, the soil must be moist, otherwise you can burn the roots.
- The second feeding is carried out when the buds are forming. Use the same bird droppings or mullein in the same proportions. A liter of solution is required for an Irbitsky potato bush.
- During flowering, this potato variety can be fed with a dry composition consisting of ash (4 spoons) and potassium sulfate (1.5 spoons) per linear meter.
In autumn, after harvesting 1 m2 area 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 suffer from common potato infections. If diseased bushes do appear, then treatment with insecticides is necessary.
If the number of pests on potatoes is insignificant (for example, the appearance of the Colorado potato beetle, potato moth or wireworm), it is possible to treat with folk remedies that will not cause damage to the soil and other inhabitants of the garden plot.
Harvesting
Irbitsky potatoes are harvested in August because they are a mid-season variety:
- In 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.
- Discard small, diseased or damaged tubers.
- Placed in pre-prepared storage for the winter.
Small tubers are not suitable for this; they will take a long time to adapt and will slowly grow when planted.

Amateurs and gardening professionals unanimously claim that Irbitsky potatoes have no drawbacks:
Conclusion
In any area, potatoes of the Irbitsky variety will come in handy. Knowing its characteristics, unpretentiousness and ability to produce a stable, early harvest, no owner will refuse such a “green guest” on his land.
