The originator of this promising variety is the GNU "South Ural Research Institute of Horticulture and Potato." Valuable features of the Spiridon potato are the highest marketability and evenness of potato root crops, as well as excellent taste.
The bushes are tall, semi-upright, well leafy, the stem part is evenly colored with characteristic anthocyanin. The leaves are medium in size, intermediate type, dark green, strongly dissected. The waviness of the edge is negligible. Corollas of flowers of medium size, reddish-purple hue. The inflorescence is medium in size, spreading.
According to the set of characteristics, the Spiridon potato variety significantly outstripped the Nevsky variety, which is widespread in homestead households, and local breeding samples from many regions.

Description of the variety and characteristics of tubers and economically important traits of the Spiridon potato make it possible to evaluate its potential for growing on private farms and on an industrial scale:
- mid-season variety;
- root crops have a smooth skin of a pronounced pink-red color and very small eyes;

- the weight of the fetus varies between 110-145 g;
- the root pulp is yellow, with a starch content of 11.9-15.8%;
- the taste qualities of Spiridon potatoes are excellent;
- tuber digestibility is moderate;
- the pulp is not prone to darkening;
- purpose of the grade "Spiridon" table;
- commodity qualities of root crops are high;

- low risk of damage to the variety "Spiridon" golden potato cyst nematode.
How to grow potatoes
The total yield reaches 240-280 kg / ha. The number of tubers per potato bush varies from 10 to 16. The marketability of tubers is 71-95%. Root-keeping indices reach 95%. The variety "Spiridon" has moderate resistance to mechanical damage, and is also moderately susceptible to damage by rhizoctonia of potato and common scab.
The correct agricultural technique of growing potatoes allows you to achieve very high results and get high yields in combination with excellent taste characteristics of harvested root crops.
The depth of embedment of planting material depends entirely on the composition of the soil. When cultivating potatoes, tubers must be planted to a depth of 6-8 cm. Growing potatoes on sandy loamy soil requires planting material to be deepened by 8-10 cm. The standard potato planting scheme is 70 x 35 cm. The tubers are planted when the soil at a depth of 10 cm is warmed up to 8 degrees Celsius.
The plant needs the least irrigation measures at the germination stage. In this phase of potato vegetation, even a slight excess of water very often provokes rotting of tubers. Abundant watering is necessary for this type of plant only at the stage from the beginning of budding to the end of flowering. Then, before withering potato tops, watering should be reduced.
The highest yield is observed when organic fertilizers are added to plants with the addition of mineral fertilizers, among which nitrogen and potassium are of the greatest importance for such a vegetable crop as potatoes. Micronutrient fertilizers are used for foliar feeding during the budding phase of potato bushes.
It is very important to keep the potato plantings clean, timely removing weeds, as well as loosening the soil and hilling potato bushes. It is very important to change the planting material every three years at most, even when growing potatoes in very fertile areas, subject to good agricultural practices and in the absence of diseases.
Reviews of vegetable growers
The combination in a modern and very promising variety "Spiridon" of high yield indicators and excellent taste, which are complemented by an attractive appearance of root crops, allows us to recommend it as a main variety for cultivation in small farms, as well as in private garden or garden plots.
How to easily spud potatoes
Due to the increased environmental plasticity under strict adherence to appropriate agricultural techniques, the Spiridon potato variety provides guaranteed good yield in any, even very adverse season. The preservation of potato tubers is very good.
The new Spiridon potato variety has high commercial value, which is confirmed by taking into account the productivity and quality of tubers, as well as the low cost of growing this vegetable crop.
