The taste of the Kurazh potato variety is rated as good and excellent. The tubers are boiled and retain a pleasant light color after heat treatment. True, not all vegetable growers agree that Kurazh potatoes are crumbly. This property of tubers depends largely on the variety, but also on the weather and fertilizing:
- Too much fertilizer increases the mass of the tuber, and starch does not have time to form;
- There is more starch in those tubers that developed primarily in dry weather.
Tubers of the Kurazh variety tolerate mechanical damage without darkening the flesh and are subject to long-distance transportation. Suitable for purees, making chips, starch.
Comment! Boiled potatoes will be crumbly if wood ash has been added.
Potatoes "Rogneda": characteristics of the variety, yield
Ragneda potatoes are productive. From 1 hectare you can collect up to 300 quintals, which corresponds to the established standard. Proper and complete care guarantees a harvest of up to 450 quintals and more per 1 hectare. It should be noted that only root vegetables with a dense consistency will be useful, since wrinkled potatoes do not have a nutritional composition.
"Rogneda" is a table potato variety that is ideal for use for culinary purposes. Potatoes can also be boiled in their skins, which will preserve the nutrients. Rogneda has ideal taste characteristics, and the potatoes are not considered too sweet and can be boiled well.

Landing
Potatoes of the Kurazh variety are planted in April or May, when the soil to a hole depth of 8-10 cm warms up to +8°C. The tubers selected for planting weigh on average 50-70 g, small ones are used, from 25-30 g, but healthy, without damage. Starting from the middle or end of March, planting material is sorted out after storage and germinated. The temperature in the room where potato vernalization takes place is 12-15°C. The sprouts grow by 1-2 cm. Large light sprouts may break during planting. To prevent them from overgrowing, Kurazh seed potatoes should not be kept for a long time at temperatures above 16°C.
- Optimal layout of potato nests: 60-70 x 30-35 cm;
- The best predecessors are all grains and legumes, perennial and annual grasses;
- On sandy soils, it is good to plant Kurazh potatoes after lupine;
- Those areas where sunflowers were grown last year are too depleted. Potatoes are planted on them only after the autumn application of a complex of fertilizers.
Advice! Before planting, Kurazh potatoes in boxes are treated with growth stimulants and insecticides, which will help avoid the first attack of Colorado potato beetles.
Landing rules
“Courage” potatoes are sensitive to cold, so they should be planted when the soil warms up to at least 8-10 °C. In the recommended regions this is usually the first ten days of May.
Comment! The variety does not tolerate cold spells and frosts. Plants will develop slowly or die.
Potatoes "Courage" prefer moderately acidic soil. The best option is sandy loam soil or light loam. The area should be bright and open. If groundwater lies close, then you need to make high beds or trenches.
The land needs to be prepared in the fall - dig up with humus and wood ash, remove weeds. In the spring, all that remains is to loosen the area and apply fertilizer. For Courage potatoes, you should choose chlorine-free formulations that dissolve well in water. Potassium sulfate and urea are effective.
Proper crop rotation is important. The culture grows well after garlic, cucumbers, green manure, onions, cabbage and legumes. Other nightshades and sunflowers are bad predecessors.
Algorithm for preparing seed and planting potatoes:
- Sort through the tubers and discard damaged specimens.
- Place them in the light in advance; sprouts should appear. The optimal length is 2 cm.
- Treat the material with a growth stimulator. The products “Elina”, “Kornevin”, “Zircon”, “Heteroauxin” are effective.
- Warm the potatoes in the sun for 1.5 hours.
- Make holes. Leave 70 cm between rows, 35 cm between neighboring plants. If the soil is light loamy, cover the tubers by 8 cm, if sandy loam - by 10 cm.
- Plant potatoes.
Comment! Excess nitrogen fertilizers lead to the growth of tops. At the same time, the tubers may become smaller.
For planting, it is better to take tubers weighing no more than 100 g
Care
The variety Kurazh is drought-resistant. The plant can develop successfully during short periods of heat, but during prolonged drought the potatoes must be watered. The plant especially needs moisture during the budding phase and after flowering. During very hot periods, the bush requires 12-20 liters of water, in normal weather - 3-6 liters. The area with Kurazh potatoes is regularly cleared of weeds and the soil is loosened, especially after watering and rain, so that a crust does not form on the surface of the soil. Air is necessary for plant roots to function normally.
Hilling and feeding
Potatoes Kurazh are hilled 2-3 times after rains or watering before flowering. The first hilling is possible even during planting, when forming a ridge that will protect the seedlings from late frosts. Usually, potatoes begin to hill when the sprouts reach 10-12 cm.
If the tops develop poorly, foliar feeding is carried out at this time. At the beginning of potato growth, the Kurazh variety is fertilized with urea, ammonium nitrate, and potassium sulfate. The second time, you can carry out foliar feeding or fertilize with mineral complexes.
Important! The main harvest of the Kurazh variety is established by fertilizing the potato plot, which is done in the fall, before plowing.
Preparing for landing
Potatoes of the Courage variety grow well if they are planted in moderately acidic soils. To keep the soil from being too acidic, it is diluted with wood ash. Potatoes are planted in places where perennial grasses, as well as flax and lupine, once grew.
If you plant potatoes in mid or late April, they will freeze. It is best to plant it in mid-May, when the soil and air are already well warmed up.
Planting material is prepared in advance. Before planting, the tubers are germinated. Usually they start doing this 1.5 months before planting potatoes in the ground. The most suitable length of sprouts for planting is 2 cm.
Diseases and pests
| Diseases/pests | Signs | Treatment |
| Late blight | There are dark spots on the leaves, which are later covered with a gray coating. In cool weather, no higher than +10°C, the fungus takes over the entire area in a matter of days. Later the tubers are affected and rot | Spraying sprouted tubers with growth stimulants, which allows Kurazh potatoes to develop faster and avoid infection. Preventive treatment with fungicides. Burning the remaining stems |
| Alternaria blight | Dark dry spots on the leaves in dry weather, with a lack of moisture, spread to the stem, the plant dries out. There are rotten spots on the tubers. Productivity decreases due to the death of the green part | The disease often affects tomatoes, so potatoes are not planted nearby. Fungicide treatment. The stems are removed and burned. The disease is caused by an imbalance between insufficient nitrogen and potassium in the soil and excess phosphorus |
| Verticillium | Develops at a temperature of 17-22°C, in the flowering phase. The leaves turn yellow and curl. The plant dies. Sometimes the disease manifests itself already on the sprouts. Tubers are wilted, with lesions | Maintaining crop rotation. The stems are mowed 10 days before harvesting. Tubers are dried and sorted before storage |
| Wireworm | The larva of a click beetle that damages tubers and roots | Destroy areas of wheatgrass where the pest lives. In early spring, bait is laid out: 3 tubers per 1 square meter. m |
Correct fit
Basic landing rules:
- It is necessary to first germinate the planting material (the optimal length of the sprouts is at least two centimeters). Planting is carried out in soil that is well warmed up to +10°C (planting date is the first ten days of May). To protect the future harvest, tubers are treated with growth regulators (Elina drug) before planting. This procedure will have a stimulating effect on the formation of tubers, helps strengthen the immune system and accelerate the emergence of seedlings;
- Moderately acidic soil (average pH value) is suitable for “Courage” potatoes;
- When planting, the distance between the bushes should be 35 cm, and the row spacing should be 70 cm. The depth is determined by the type of soil: on light sandy soils the planting depth is 10 cm, and on light loamy soils up to 8 cm.
Further care consists of watering, fertilizing, weeding and hilling.
Potatoes, like other vegetables, need moisture. Water consumption is calculated based on the composition of the soil. During rainy summers there is no need for additional watering. During dry periods, potatoes are watered. This procedure is carried out throughout the growing season, as soon as the soil is completely dry.
Necessary fertilizers:
- The main difference of this variety is its rapid growth, so fertilizing is carried out only once per season. The first time is fed immediately before planting, mixing the fertilizer well with the soil, avoiding the substance getting on the root crops;
- The main feeding is carried out as soon as the bushes get stronger, using urea, ammonium nitrate and potassium sulfate.
Weeding and loosening the soil
- Periodically remove weeds, as they absorb moisture and are also a possible cause of insect pests on potato bushes;
- The soil must be loose for easy movement of oxygen.
Hilling
During the season, potatoes are hilled three times. The first time when the plant reaches a height of more than 10 cm, the second time two to three weeks after the first, during flowering. The last hilling is carried out as soon as the bushes reach 20-25 cm.
Key rules for growing "Courage"
This type of potato belongs to the table type, but if you delve into the study of its main characteristics, it becomes clear that it can also be used for processing into pure starch in industry.
But first you need to carefully study the basic rules for caring for and growing potatoes. If they are neglected, the plants will die in the shortest possible time, never having matured.
Landing
It is extremely important to choose the right time for planting “Courage”. This potato variety has serious resistance to high temperatures, but it succumbs to cold weather and frosts. And in the regions prescribed for “Courage”, there can be cold weather even in May. If young shoots do survive cold spells and frosts, their growth and development may be affected, causing the fruit to be of much lower quality than it should be.
The ideal time for planting is the first 10 days of May (approximately, because it all depends on the temperature).
Planting material should be germinated in advance (at least 20 mm of the length of sprouts on tubers), and it should be planted in soil heated to approximately 10 degrees.
Reviews
Most gardeners leave only positive reviews about the crop.
Antonina, Moscow : “I like this variety due to its unpretentiousness and high yield.
You can make anything you want from potatoes: first and second courses, pie filling, and all kinds of salads. The seedlings do not get sick, but I definitely carry out preventive measures against late blight. This is not the first year I have been planting Courage and I will plant it again.” Anatoly, Lipetsk region : “I am planting several early varieties for sale. The peculiarity of Courage is that it not only does not get sick, but also produces a larger harvest than other varieties. That’s why I plant it most of all, especially since the rounded tubers with red skin are readily sold out.”
