Advantages and disadvantages
Excellent consumer qualities: even tubers, pleasant taste, starchiness
Less storage time than other early varieties
The rapid decline in yield, if the planting material of low reproduction
Immunity to a number of dangerous diseases of culture
Susceptibility of a tops to a fitoftor
Potato variety Kurazh planted in April or May, when the soil at the depth of the hole - up to 8-10 cm warms up to + 8 ° C. Tubers selected for planting, weigh an average of 50-70 g, and use small, from 25-30 g, but healthy, without damage. Starting from the middle or end of March, planting material is sorted after storage and germinated. The temperature in the room where the potato vernalization takes place is 12-15 ° C. Sprouts grow by 1-2 cm. Large light sprouts may break during planting. So that they do not outgrow, it is forbidden to keep seed potatoes Kurazh for a long time at temperatures above 16 ° С
- The optimal layout of potato nests: 60-70 x 30-35 cm;
- The best predecessors are all cereals and legumes, perennial and annual herbs;
- On sandy soils potatoes Kurazh well planted after lupine;
- Those areas where sunflower was grown in the past year are too exhausted. Potatoes are planted on them only after the autumn fertilization of the complex.
Variety Courage drought-resistant. The plant can successfully develop during short periods of heat, but in a long drought the potatoes must be watered. The plant especially needs moisture in the budding phase and after flowering. In very hot periods for the bush requires 12-20 liters of water, in normal weather - 3-6 liters. The plot with potato Courage is regularly cleaned from weeds and loosened the ground, especially after irrigation and rain, so that a crust does not form on the surface of the soil. Air is necessary for the roots of plants for normal life.
Hilling and feeding
Steam potato spud 2-3 times after rains or watering before flowering. The first hilling is possible even when planting, during the formation of the ridge, which will protect the seedlings from late frosts. Usually, potatoes begin to spud when sprouts rise to 10-12 cm.
With a weak development of the tops, foliar dressings are carried out at this time. At the beginning of the growth of potato variety Kurazh fertilized with urea, ammonium nitrate, potassium sulfate.

The main crop of Variety is laid by fertilizing the plot for potatoes, which is carried out in the autumn, before plowing.
Diseases and pests
Diseases / pests
On the leaves are dark spots that later become covered with gray bloom. In cool weather, not above + 10 ° C, the fungus captures the entire area in a matter of days. Later tubers are affected and rot
Spraying of the germinated tubers with growth stimulants, which allows the Kurazh potato to be able to avoid infection by a more rapid development. Preventive treatment with fungicides. Burning stalk residues
Dark dry spots on the leaves in dry weather, with a lack of moisture spread to the stem, the plant dries out. On tubers rotten spots. The yield decreases due to the death of the green part
The disease often affects tomatoes, so the potatoes are not planted nearby. Fungicide treatment. The stems are removed and burned. The disease is triggered by an imbalance between an insufficient amount of nitrogen and potassium in the soil and an excess of phosphorus.
It develops at a temperature of 17-22 ° C, in the flowering phase. The leaves turn yellow, curled. The plant dies. Sometimes the disease manifests itself already on the shoots. Faded tubers with lesions
Compliance with crop rotation. Stems mow 10 days before harvesting. Tubers are dried and sorted before storage.
Larva of the click beetle that damages tubers and roots
Destroy the areas of wheatgrass on which the pest lives. In early spring, lay the bait: 3 tubers per 1 square. m
Stems potato Courage mow 7-10 days before harvesting for better ripening and prevention of possible infection. After digging, dried for several hours on the field, then cleaned in a dark room. Before putting it into storage, sort it out again.
