Prepares quickly. During cooking, it does not change color and does not crumble. Contains vitamin C and other beneficial substances. The amount of starch is average.
Pros and cons of Krasa variety
New varieties are created with improved qualities. The entry of the variety into the State Register of Breeding Achievements guarantees a positive cultivation result. No flaws were found in the young variety.
Advantages of the variety:
- excellent taste;
- large, even tubers;
- consistently high yield;
- bush resistance to lodging;
- disease resistance.
The positive qualities also include the availability of growing a culture of the Krasa variety from seeds. Botanical seeds of the crop are free from diseases, which makes it possible to obtain a high and high-quality crop for many years.
Planting and caring for Krasa potatoes
It is recommended to grow potatoes of the Krasa variety with botanical seeds using a seedling method. Seed propagation allows for the renewal of planting material. After all, it is known that after 5-6 years of growing a culture of the same variety, many diseases accumulate in the tubers and degeneration occurs. Botanical potato seeds do not accumulate pathogenic microflora.
The seedling method of growing potatoes is similar to the closely related nightshade crop - tomatoes. But in the first year of growing, seed potatoes only provide planting material for the next season.
Stages of growing a culture of the Krasa variety from seeds:
- Potato seeds have a low germination capacity, so they are pre-soaked for several days in a damp cloth for pecking.
- To increase immunity, the seeds are hardened, leaving them soaked overnight in the refrigerator at a temperature of + 1 ° C, and for a day they are taken out and left at room temperature.
- Sowing begins in the last decade of March.
- The root system of potatoes forms slowly, so the soil must be highly fertile and loose.
- Before planting, the seeds, like the soil, must be disinfected in a fungicide solution. Seedlings of potatoes are more often than other nightshade crops affected by a fungal disease - a black leg.
- After the seeds are nailed, they are laid out on wet soil without deepening. Even slightly buried seeds will not have enough growth force to get out of the soil.
- Crops are covered before germination, which will take from a week to two. Seedlings should be in the most lighted place all the time.
- Watering is carried out with great care, from a small watering can along the edge of the container or with a pipette (syringe) next to the sprouts. You cannot spray crops from a spray bottle - this method can harm them.
- During the rooting period, seedlings are fertilized with ammonium nitrate.
- Potato seedlings are very small and thin and require the most careful handling, including at the moment of picking, which is carried out at the stage of two true leaves.
Further cultivation of seedlings is possible in greenhouses or open ground.
Young plants are sensitive to temperature drop. Therefore, they are transferred to open ground when constant positive temperatures are established. At the beginning of growth, seedlings in the open field are covered with a film that protects against temperature extremes. Further agricultural techniques for seedlings are used the same as for potatoes grown from tubers.
Selection and preparation of the landing site
The place for planting Kras potatoes is chosen on a hill, with good illumination. Lowlands where moisture stagnates are not suitable for cultivation. In such an environment, the possibility of rotting tubers and the occurrence of various fungal infections increases. The landing site is prepared in advance, from the previous season.
Before planting, the soil must be enriched with organic matter or mineral fertilizers must be used. The soil for growing a culture of the Krasa variety should be light, with low acidity.
The site is chosen one on which the cultures of the Solanaceae family have not grown before. This is especially important for planting clean plants from seeds. Fields work best after growing cabbage, squash, and legumes.
Preparation of planting material
Potatoes Krasa must be prepared before planting. This is necessary to accelerate germination and friendly growth of culture. The first training is carried out in the fall. Before storing seed potatoes, they are calibrated and greened. Uniform tubers allow seedlings to appear at about the same time. And greening increases the yield by 20-30%. The Kras potatoes are planted for 2 weeks, leaving the selected tubers spread out in diffused light.
In the spring, 1-1.5 months before planting, the tubers begin to germinate in order to awaken their growth. For this, the tubers are laid out in a bright, warm place. When sprouts appear, they are deployed towards the light source. At the germination stage, it becomes possible to reject diseased tubers, for example, the sprouts of which are black.
Before planting, the tubers are sprayed with a fungicide solution, which gives additional protection against possible diseases that may be in the soil.
Landing rules
Planting potatoes or their seedlings in open ground is carried out when the soil warms up to a depth of 10 cm and higher up to + 7 ° С. The soil suitable for planting should be dry, it does not get dirty, crumbly and light. The planting site must be clear of weeds.
The depth of planting in the hole is about 7 cm, the fruit is lowered by seedlings. When planting seedlings and tubers, the distance between them is observed at 70 cm.
Mineral or organic fertilizers can be added to the hole, depending on the original soil fertility.
When fertilizing the hole, it is necessary to cover them with earth and only then lower the fruit. It should not come into direct contact with fertilizers. Mustard cake is considered an excellent organic fertilizer. In terms of nutritional qualities, it surpasses manure. A handful of mustard cake is introduced into the hole and mixed with the soil.
Watering and feeding
In a dry period on a dried soil, potatoes yield a yield that is 2 times less. Watering is best done in furrows, intensified during flowering and stopped before harvesting.
The culture is demanding on the fertility of the soil, which is fertilized in advance or when planting.
Loosening and weeding
Loosening and weeding is necessary to improve air exchange and the formation of high-quality, large tubers. Weeds have a high vigor and a stronger root system. Blocking potato plantings, they draw out moisture and nutrients, especially in the first growing period.
Several weeding may be required during the season, some of which are combined with hilling. Weeds are removed manually or using manual and mechanical devices.
Hilling
Hilling is carried out several times during the growing season. To do this, under the potato bush, they rake the earth until high ridges are formed. An alternative method to hilling is to mulch potato bushes with grass. Mulching maintains the required moisture level and eliminates loosening and weeding.
Diseases and pests
A crop grown from depleted planting material, as well as with a lack of crop rotation, is more susceptible to diseases. The renewed sowing potatoes are genetically resistant to diseases, they allow to harvest a consistently good harvest for 5-6 years.
Krasa potatoes are resistant to the following diseases:
- potato crayfish;
- golden nematode;
- striped wrinkled mosaic;
- curling leaves;
- moderately to late blight of tubers and tops.
Pests affecting plant tops include:
- Colorado beetle;
- various fleas;
- caterpillars.
The tubers are damaged by the wireworm larva of the leaf beetle, as well as beetle and bear. Pests are selected manually, biological products containing bacteria are used. And for large areas of infection, insecticides are used.
Potato yield
The yield of potatoes directly depends on the methods of growing, the climatic characteristics of the season. Under favorable conditions, Krasa potatoes form 6-8 even, large tubers from one bush.
Harvesting and storage
The harvesting of Krasa potatoes begins after 80-100 days, which falls on the month of August. The signs of potato readiness for harvesting are drying of the tops and thickening of the skin. Harvested in dry, sunny weather. Potatoes have excellent keeping quality when stored in dry rooms, at a temperature of + 2 ... + 4 ° C.
Conclusion
Description of the Krasa potato variety, photos and reviews represent a young crop selection with excellent characteristics. The producer of the variety offers to grow Krasa potatoes from seeds. This method allows you to get your own, healthy planting material and high productivity.
