Potatoes are considered the most popular vegetable crop, so the choice of a variety for growing is of great importance. Basically, preference is given to table plants that combine good yields, high taste, resistance to pests and diseases, as well as the ability to store for a long time. All these qualities are distinguished by German potato varieties, which include Zest.
Characteristics and botanical description
The variety went through a long selection process, therefore, as a result, high yield rates were achieved in combination with increased resistance to the negative effects of fungal and viral diseases.
Potatoes Raisin
Potatoes of German breeding variety Izuminka are a mid-season variety of culture, therefore, the ripening period of tubers is 95-110 days after the appearance of the first shoots. This allows it to be used for long-term storage while maintaining all the useful and taste qualities.
The main characteristics of the middle-ripening potato variety Izuminka:
- yield - 500-520 c / ha;
- weight of 1 tuber - 100-150 g;
- starch content - 16-18%;
- storage level - 93%;
- preservation of commercial qualities - 94%.
During the growing season, this species forms a compact potato bush with erect shoots, 60-70 cm high, depending on the growing conditions. The flowering period occurs within 26-28 days, after germination of seedlings. The variety is distinguished by purple flowers with a red tint. Medium-sized leaves have a deep green color with a shiny surface.
A highlight during flowering
The variety is characterized by oblong tubers with shallow eyes, which at technical maturity have a smooth surface, and by the time of full ripeness they acquire a characteristic roughness. The skin of the fruit is red and the pulp is yellow. Subject to the requirements of agricultural technology, the number of harvested tubers from 1 bush reaches 15 pieces, mostly medium and large in size.
This type of potato is distinguished by its relative resistance to nematodes, mosaics and the virus that provokes foliage curling.
Potato Zest is not boiled, and the taste is estimated at 4.5 points on a 5-point scale. Ideal for soups, baked potatoes and side dishes, the flesh does not darken as it cooks.
Features of agricultural technology
Based on the varietal affiliation, the planting of the Raisin should be carried out no earlier than May, and additional germination of seed material is not required. To obtain the maximum yield, medium-sized seed tubers with well-developed eyes are selected. The soil temperature during planting should not be lower than 10 degrees.
The planting density should not exceed 5-6 bushes per 1 square meter, while the row spacing is 0.7 m. The gap between the planting holes should be 25-30 cm, which guarantees uniform development of bushes and the formation of tubers in full.
Optimal distance for planting potatoes
Planting depth is of particular importance when growing potatoes of this variety, so the following rules should be observed:
- on a hill with average soil composition, potatoes must be buried in the ridges within 6-9 cm;
- in an area with light drained soil, this variety should be planted at a depth of 10-12 cm.
Variety Raisin is resistant to drought, but in the absence of seasonal rainfall, it needs additional watering during the period of budding and flowering. In addition, you should worry about the timely introduction of organic and mineral fertilizers during planting and during the growing season of the crop.
Fertilization during planting
Harvesting should start in mid-September, after the tops turn yellow, in dry weather, which guarantees the safety of tubers for 9-10 months.
Advantages and disadvantages of the variety
Varietal potatoes Raisin has its advantages and disadvantages; for successful cultivation of a crop, you should study them in advance.

Disadvantages of the Zest variety:
- the taste of the fruit manifests itself when fully ripe;
- has medium resistance to pests;
- does not tolerate sprouting of tubers in spring.
- long ripening period;
In all respects, this potato variety is suitable for widespread cultivation in the regions of the middle belt and southern regions. You can buy seed material in Moscow in specialized retail and online stores with the provision of the necessary quality certificates.
