The figures correspond to the average indicators for the level of accumulation of the substance on which the boilability of the tuber depends. Tasters gave the variety a taste rating of 4 to 5 points.
Pros and cons of the Jura variety
Potatoes have proven to be high-yielding and hardy in cool summer conditions and frequent rainfall, typical for areas of the Central region, where the variety is recommended for cultivation.

- early production;
- good yield in the group of mid-early varieties;
- high marketability of tubers;
- excellent keeping quality;
- versatility;
- pleasant taste of dishes;
- unpretentiousness to the weather conditions of central Russia;
- resistance to a number of diseases.

- before plowing, add 6-8 kg of humus or manure;
- 30 g of superphosphate;
- You can add humus before spring cultivation;
- Directly during planting, 130-180 g of wood ash is placed at the bottom of the hole.
Preparation of planting material
Jura potato tubers, according to the description of the variety, photos and reviews, form strong light sprouts after special preparation. A month before planting, seed potatoes are lifted from the cellars into the light for germination. The tubers are laid out in 2-3 layers in wooden or plastic boxes and placed in a bright, cool room. The temperature should not rise above + 14-15 °C so that the sprouts do not stretch. After proper vernalization, the shoots reach 0.5-1.2 cm.
Landing rules
In an effort to get a rich harvest of the Jura variety, they adhere to generally accepted rules:
- planting is carried out when the soil at the depth of potato placement warms up to 10-12 °C;
- on structured loams and sandy loams, the hole depth for the mid-early variety is 8-10 cm;
- on heavy clay soils, Jura potatoes are planted at a depth of 5-6 cm;
- optimal placement scheme for a small bush Isle of Jura - 50x60 cm;
- The location of the light sprouts when planting does not affect the potato yield.
Watering and fertilizing
Judging by the characteristics of the variety and reviews of Jura potatoes, the moisture-loving crop is regularly watered if there is insufficient rainfall:
- the beginning of watering - in the phase of 13-15 cm of stem height, 2.5-3.5 liters for each plant;
- when buds form, the bushes are watered with 6-7 liters;
- during the period of tuber formation they give 10-12 liters.
Organic fertilizers are not enough for good yield of the Jura variety. Potatoes are fed with complex mineral and organomineral fertilizers:
- "AVA";
- "Kemira";
- "Crystalon";
- "WMD";
- "Bulba" and others.
After the first watering or earlier, foliar feeding is carried out. To treat leaves, prepare a mixture in 10 liters of water:
- 90-110 g urea;
- 150 g of potassium monophosphate;
- 5 g boric acid.
After 2-3 weeks, feed again in the same way, but in a higher concentration - per 5 liters of water.
Loosening and weeding
Potato plantings are regularly looked after. After watering, loosen the soil with light tools without damaging the tubers. Weeds deleted.
Hilling
The characteristics of the Jura potato emphasize that the variety is moisture-loving. Hilling will help create a convenient environment for the tubers to gain weight.

Diseases and pests
Jura potatoes are resistant to cancer, common scab, black leg and late blight of tubers, and are not affected by the golden nematode. If late blight fungi begin to spread early, plants may suffer. Preventive spraying with fungicides “Oxyx” and “Ridomil” is recommended.
To protect tubers from wireworms and cutworms, remove weeds around the potato area. Insecticides are used against aphids and whiteflies. Colorado potato beetles are controlled with special preparations.
Potato yield
The mass of tubers of the Jura variety is from 90 to 190 g. From 6 to 10 potatoes are formed in the nest. At a summer cottage, you can get 1-2 kg from each bush, which depends on the fertility of the soil, the regularity of watering and fertilizing.
