Characteristics of the potato variety Irbitsky
For gardeners of the Volga-Vyatka, Ural regions and Western Siberia, Irbitsky potato will be a successful acquisition. This is one of the new varieties of Russian selection, which allows you to collect enough crop from a small summer cottage to provide your family with winter supplies.
Characteristics of the potato variety Irbitsky
Irbit potatoes passed state registration in 2012, it is recommended for cultivation in areas with a temperate continental climate.
The variety is medium early ripening. From the appearance of seedlings to technical ripeness, 65-80 days pass. A description of the Irbitsky potato variety was given by its originator, the Ural Scientific Research Institute of Agricultural Sciences. The bush is semi-erect, medium sized, intermediate type (between compact and spreading). The tops are dark green.
A medium-sized leaf, moderately dissected, forms large inflorescences with red-violet corollas. The tubers are round, red, weighing 110-180 g. Usually, 6-8 tubers with a total weight of up to 2 or more kilograms are formed under the bush. The skin is thin, smooth, with small eyes. The pulp is light yellow. Potato has good taste, medium digestibility. The starch content is 12-16%.
Advantages and disadvantages of the variety
Variety Irbitsky has a number of characteristics, thanks to which summer residents acquire for planting its planting material of the super elite class:
- Adaptability to agroclimatic conditions. According to the State Register, the culture is recommended for 3 regions of the Russian Federation, but it is successfully grown in other territories of the Russian Federation and abroad.
- High productivity: from 1 ha, 255 to 390 centners are harvested, the maximum figure is 468 centners.
- The possibility of long-term storage.
- Widespread use in cooking.
- Moderate resistance to many diseases: potato cancer, different types of mosaics, viruses X, Y, L, S, nematode.
According to the description, the variety has no particular drawbacks. Like any other kind of potato, this one shows large yields under a number of conditions.
One of the necessary requirements is high-quality planting material. It is better if it is a superelite or elite, i.e. tubers that have all varietal qualities and have not accumulated disease. Preparation takes place traditionally. In the fall, they take care of the soil.
For cultivation, a well-lit area is allocated. The soil characteristic most acceptable for the Irbit potato variety is as follows: loose, fertile, slightly acidic, although the variety will grow on any soil. It is not recommended to grow a crop in one place for more than 2-3 years, after other members of the nightshade family, to place beds next to plantings of tomatoes, eggplants, bell peppers. The best precursors for potatoes are legumes, perennial herbs.
Fertilizers are applied to the soil during autumn digging or in the spring, immediately before planting potatoes.
The plant needs both organic and inorganic fertilizers. The minimum set is humus, wood ash, nitrophoska. The dosage depends on the characteristics of the soil, If the earth is clayey, heavy, per 1 square. m spend a bucket of humus or peat, 1 tbsp. wood ash, 2 tbsp. l nitrofoski. Sandy soils need regular fertilizer application to improve structure, increase water retention and fertility.
Before planting, seed potatoes are prepared. The sequence of actions is as follows:
- 3-4 weeks before planting, damaged tubers are selected, transferred from storage to a warm, bright room for germination and greening (it is better to put it in 1-2 layers);
- after the sprouts reached 2-3 cm, carry out calibration;
- immediately before planting in the soil, large potatoes are cut into several parts so that each contains 2-3 sprouts;
- treat planting material with a composition including insecticides (if there is a threat of pest damage) and growth stimulants, use a solution of potassium permanganate.
Only healthy tubers are suitable for planting.
Tubers are recommended to be planted after the soil has warmed up to a temperature of 5-8 ° C to a depth of 10 cm. Failure to meet the deadlines leads to a delay in development and a significant decrease in yield (up to 20%).
Irbitsky potatoes are closed in holes located 60 cm from one another. The distance in the row is 35 cm, the depth is 8-10 cm. If the plot has not been fertilized earlier, humus and ash can be added directly to the hole. In no case should you use unripe manure.
The variety is unpretentious in care. It is enough to follow the simple rules common to this culture.
The variety tolerates drought well, but needs watering during the period of budding, flowering and tuberization. The first watering is carried out after emergence. If there is no rain in July, early August, and the earth dries up, it is necessary to lower the soil temperature and extend the growing season with abundant watering, but the moisture in the area should not stagnate.
Watering is carried out after hilling and combined with fertilizer application. The formation of a crust must not be allowed, the soil must be loosened, weeds are destroyed.
A special procedure that any sort of potato needs is hilling. It is carried out at least 2 times a season to create conditions for tying tubers, better aeration. The first time they wind up when the plants are stretched to 15 cm. At the same time, a high earthen crest is poured - up to 20 cm. The next hilling is carried out before closing the tops.
Like all varieties of medium-term ripening, Irbitsky potato is especially in need of nutrients during the period of intensive growth of tops and the beginning of tuberization. The balance of nitrogen, phosphorus and potash fertilizers must be observed. The predominance of nitrogen will lead to a rapid increase in green mass and a decrease in the quantity and quality of the crop.
The first top dressing is carried out after the first hilling. To do this, use a liquid mixture of inorganic fertilizers. In one bucket of water bred:
- 30 g of nitrogen fertilizers;
- 30 g potash;
- 60 g of phosphoric.
It is advisable to fertilize with organic fertilizers. Effective chicken droppings. Fresh can not be used. Gardeners usually prepare slurry: they breed litter in water in a proportion of 1:15 and leave it to be fermented in a closed container for several days. The norms for using such top dressing are no more than 1 liter per bush.
You need to fertilize the plant after watering, pouring fertilizer into the wells. These nutrient mixtures must not be allowed to reach the tops.
Foliar top dressing is effective for culture, especially at the stage of growing green mass, during flowering and tuber formation. Urea plants use urea (per 5 l of water, 100 g of urea, 150 g of potassium monophosphate, 5 g of boric acid) and phosphorus (per 10 l of water, 100 g of superphosphate) fertilizers.
You can feed on the sheet and organic fertilizers. To do this, use solutions of humates, nettle infusion, rich in trace elements. To prepare such an infusion, nettle is poured with water, left to ferment, then filtered, diluted with water. Such foliar top dressing can be carried out after the formation of 4 of this sheet with an interval of 10-14 days.
Since the variety is resistant to most diseases, the main threat to the crop is pests. The most dangerous pest, especially in the southern regions, is the Colorado potato beetle. To combat it, mechanical (collection of larvae and adult beetles) and chemical methods are used. Effective insecticides and biological products (Aktara, Bankol, Bikol, Regent, Colorado, etc.) are purchased at specialized outlets. If the number of larvae is small, you can use self-prepared herbal preparations. It can be daily infusions of wormwood, walnut leaves, celandine or decoctions of dandelions, hot peppers.
The introduction of Bazudin granules during spring soil preparation will help prevent tuber damage by wireworm. To destroy the bear, which damages young tubers and gnaws stolons, it is necessary to introduce “Wofatox” or “Medvetox” into the soil to a depth of 2-3 cm.
In late July - early August, you can already dig up young potatoes. But if you are aiming at harvesting the maximum yield, you must wait until the tubers are fully ripened.
To increase productivity among summer residents and gardeners, cutting tops is practiced 10-14 days before harvesting. It can be composted and used as a valuable fertilizer. Extracts from fresh or dried tops - a preparation for combating many pests of the garden.
