Description of the onion variety sevka centurion and its characteristics
Most gardeners and large-scale farms prefer the promising Centurion onion variety for undemanding care, high-quality harvest and long shelf life.
The widespread vegetable crop belongs to the medium early varieties of the Dutch selection. It is a reliable hybrid and shows excellent germination results.
Description and characteristics of the centurion onion variety
Let's start with a description of the variety. The plant reaches a height of 80 cm and has tubular leavescolored deep green. The variety forms medium-sized heads. The weight of one onion ranges from 100 to 150g. The bulb is round, slightly elongated with a dense husk that has a bright straw color. A small neck creates a reliable barrier against pathogenic microbes entering the white pulp, which protects the onion from decay.
Due to its shape, small bottom and narrow neck, the vegetable is convenient for cutting, unlike other types that have a spherical shape, which give a lot of waste. And the taste of the product, which is characterized by light pungency, piquancy and delicate aroma, absolutely satisfies the requirements of culinary experts.
The variety has a lot of advantages, because of which it is of particular interest to vegetable growers. Positive characteristics include:
- high yield, from 1 m2 of plantings can be harvested from 4 kg of turnips;
- successful growth in various climatic zones;
- excellent taste of the variety;
- resistance to arrowheading, so the variety is well suited for growing on feathers;
- disease resistance, characteristic of this variety, because of this, it does not need additional processing with the use of chemicals;
- well suited for long-term storage at home;
- a universal product, used both fresh and suitable for canning.
The peculiarity and characteristics of the variety allows Centurion to enter the highest price category, which guarantees a decent profit for commercial cultivation.
To provide the whole family with onion reserves for the winter, certain rules and requirements must be observed when planting a vegetable crop.
When building this variety, it is important to correctly determine the timing of planting., because a very early planting can expose vegetables to freezing, and a late planting will not allow the bulbs and feathers to fully develop.
The main condition is that the soil warms up to 15̊C heat and if it is not observed, the harvest may be small.
When choosing a landing site, you need to pay attention to open and well-lit areas. Although the culture is hygrophilous, it does not tolerate an excessive amount of water, so you should avoid places where groundwater passes close to the surface of the earth.
Sandy loam soils are best suited for the Centurion variety. The acidity level should be neutral, as acidic soil leads to a significant loss of yield. To reduce acidity, furnace ash or cement dust can be added a year before planting.
The soil should be prepared in the fall by performing the following agrotechnical techniques:
- Clear the selected area from weeds, as they negatively affect the quality and quantity of the crop.
- Apply fertilizer while loosening the topsoil. This will help nutrients get deeper, as well as additionally eliminate weed residues;
- Before the winter period, dig up the beds to a depth of about 25 cm.
This culture is not recommended to be planted in the land of last year's planting; its location should be changed. The next time it will be possible to plant a plant in the same area only after 3 years.
Record yields can be obtained with a two-year growing scheme.
Features of growing in the first year
The end of April - beginning of May is considered a favorable period for sowing seeds. The sowing process includes the following procedure:
- Soak the seeds in water for 24 hours before sowing. Growth stimulants can be added to the water. Then put the seeds on a cloth and cover with foil.
- Prepare seed furrows 3-4 cm deep, keeping a distance of 20 cm between them.
- Equip the bottom of the furrow with fertilizers and evenly place the planting material at the rate of 3g of seeds per 1m2.
- Pour loose soil on top and compact it a little.
The yield of seedlings can exceed 15 tons per hectare. You can harvest the sevok 90 days after sowing. After that, it must be prepared for storage and placed for the winter in a specially designated room with an acceptable temperature and humidity level.
Basic rules for the second year of growing
First, it is necessary to sort out the sevok, removing damaged and rotten specimens. Then warm up the selected bulbs for planting under a cover for 3 days and proceed to the process of planting seedlings.
- Make planting holes, the depth of which is 6-8 cm. The distance between the rows should be within 10-12 cm.
- Introduce organic matter, which can be rotted manure, wood ash.
- Place the set in the prepared holes with a distance of 8 cm from each other.
- Cover the wells with earth and tamp lightly.
The onset of technical maturity occurs in 75 days. The crop can be harvested at the end of July - beginning of August.
A set of measures for the care of onions
When growing any vegetable crop, not only proper planting is important, but also further care, which must be performed in accordance with all the rules. This requires:
- Conduct regular watering during the growing season to activate leaf growth, which should be reduced by the end of vegetative growth, and completely stopped 3 weeks before harvesting. Watering should be done carefully, without damaging the pen. Use only warm water, as cold water can provoke the appearance of downy mildew.
- Weed together with loosening land to ensure good air exchange, this will have a positive effect on the development of vegetable crops;
- In due time to clear weeds, since they help to maintain moisture on the surface, which leads to an increased risk of resistance to various fungal diseases. Also, if the weeds are not destroyed in time, the neck will become juicy and this will negatively affect the storage of the vegetable, as it will begin to rot.
- Introduce nutrients, depending on the soil in which the onion is planted.
- Constantly inspect plants for diseases and pests and, if detected, take appropriate measures.
Diseases and their prevention
The most common pest of the Centurion onion is the onion fly. When exposed to it, the leaves are incapable of such a process as turgor and, turning yellow, curl. It is necessary to get rid of the pest as soon as possible, since not only the leaves are affected, but also the stalk with seeds. There are many folk remedies and chemicals that are actively used in the fight against onion fly.
Onion moth, small brown butterflies can also be a dangerous pest. The harm is brought to a greater extent not by adult organisms, but by the larvae that eat away the plant parenchyma. For the purpose of prevention, you need to regularly weed the beds, and rationally distribute crops. PWhen treating onions, substances are used, the smell of which repels insects. It can be either a chemical product purchased in a store or prepared at home.
A wet spring with low temperatures provokes the appearance of downy mildew. Since rainwater accumulates on the leaves of onions and accelerates the development of fungal diseases, when they appear, the entire garden can be infected in just a few days. For prevention and treatment, it is worth using fungicides every 2 weeks.
A very dangerous bacterial disease of the Centurion onion is bottom rot, which enters the plant through contaminated soil and is accompanied by complete decay of the plant.... You can get rid of the disease only by using special means.
In order for the onion to grow healthy and not contain insect larvae, it is necessary to take timely measures to combat pests and diseases.
Harvesting and storage rules
With professional fit and proper care, you can easily achieve the desired results. The onion harvesting period begins at the moment when the leaves fall, and the neck is not able to keep them evenly.
Zand a few weeks before harvesting, you need to stop watering and dry the soil a little. Cut the bulbs carefully without damaging the bottom. Before harvesting for storage, you need to carefully consider each bulb and set aside all suspicious specimens for use in the first place.
It is necessary to place the harvested crop in the sun and let it dry a little. In rainy weather, place it under a canopy, ensuring sufficient air circulation. Then put the onion in wooden boxes, nylon bags or nets. You can store vegetables in bulk.
If the required conditions are observed, the storage period can be up to 8 months. It is important that the room in which the vegetables are placed is dark, cool and dry.
Centurion onion surprises with its spicy taste, which makes it a popular and demanded product in the preparation of culinary masterpieces. If you follow all agrotechnical methods for the construction and follow the necessary care recommendations, you can harvest an excellent harvest of large onions.
The Centurion onion was bred in Holland by a group of professional breeders and belongs to hybrids. The vegetative cycle is two years. In the first year, nigella is planted and sets are grown, and the next year, sets are planted and turnips are obtained. The ripening period is medium early - just 90-110 days after planting, you can harvest.
The pulp is white, with a high juice content
Onion head weight is 90-100 g on average. The shape is elongated. The head of the onion has a narrow base and a thin neck, which greatly simplifies cleaning. The husk is golden brown, dry. The head is dense. The pulp is white, with a high juice content. The taste is pleasant, versatile. This onion is suitable for fresh salads and for cooking. You can eat not only the head of this onion, but also the feathers.
Winter varieties of onion sets
Winter onion varieties are those that are preferably planted in the fall so that they overwinter in the soil and begin to develop in early spring. Moreover, it is not recommended to plant varieties for spring cultivation as winter crops: they shoot more actively and do not tolerate frosts well, and in a harsh winter, a bed of them will not survive until spring. Therefore, when buying, you must initially choose exactly the onion that is intended for growing winter crops, and for planting in the spring, take a separate variety.
The best and most convenient varieties of onion sets for winter planting are those that are bred in Holland. Dutch varieties are among the most resistant and productive varieties. Here are examples of such varieties: "Shakespeare", "Troy", "Radar". But they do not exhaust the entire list of onion types for winter sowing. And an inexperienced gardener should read the advice of more experienced colleagues in order to know which variety to choose. Some varieties of winter onions that are popular with site owners will be described below.
Onion variety "Shakespeare"
This semi-sharp variety has a number of beneficial properties that make it one of the best varieties for winter planting.
It has the most frost-resistant bulbs, making it ideal for growing in central Russia. Shakespeare has dense and strong surface scales, which allows the seed to transfer frosts down to -18 ° C. For the same reason, it is stored for a long time, retaining all its taste. If a gardener is looking for varieties of onion sets for the Moscow region and other regions with the same climate, then Shakespeare will suit him to the fullest.
For inexperienced gardeners, this onion is also recommended because of its resistance to various diseases and pests. But it should be remembered that it is intended specifically for winter cultivation. If you plant it in the spring, then there will be no big harvest.
It is not difficult to recognize the bulbs by their appearance. This vegetable has a dense, smooth and shiny rind of golden red color. The pulp is white, dense. The weight of an individual bulb reaches 100 g, which is a lot. At the same time, the variety is distinguished by its yield, for which the owners of the plots also appreciate it. Ripening time - 2.5 months, although the period may vary depending on climatic conditions.
Onion variety "Troy"
Like the previous variety, this is a Dutch onion, and they are similar in their characteristics and description.
Troy is a relatively new variety, but it is a very successful and easy-to-grow hybrid. It is worth remembering that he, like all hybrids, is not suitable for breeding: the bulbs of the second generation never adopt the qualities that distinguish the first. It is not suitable for breeding for greens.
These are onions, which, despite their medium size, are distinguished by their yield. From 1 sq. m of the garden, you can get 5 or more kilograms of vegetables.
Although this variety is not spicy, it can be stored for a long time. The shelf life at which the bulbs do not deteriorate and do not lose their taste is 115-125 days. Ripens early. In the middle lane, the crop is harvested in July or early August. It is not prone to shooting, which is why both planting material and ripe bulbs are stored for a long time. The rhizomes have a rounded shape with dense golden scales. The pulp is white, dense.
This variety is suitable both for pickling and for use in salads. Another advantage of this variety, for which experienced gardeners appreciate it so much, is its resistance to diseases and pests. He is not completely protected from them, but he does not get sick often, which has a positive effect on the harvest.
Onion variety "Radar"
Another Dutch variety for winter sowing, which is loved by many gardeners.
A distinctive feature of the Radar is the size of its bulbs. The average weight of one fruit is 150-200 g, although it can reach a weight of 0.5 kg. The pulp is very dense, white, semi-sharp, with a pleasant taste. The shape of the bulbs resembles a somewhat flattened ball. The scales are dense and strong, of a golden hue.
This variety easily withstands even severe frosts. It will lie perfectly in the soil all winter, and then it will give an early harvest.
This type of onion is very resistant to diseases. Although pests such as onion fly and stem nematode are still dangerous to Radar.
According to many gardeners, this variety begins to bear fruit as early as May, subject to correct sowing. This is an added benefit that is also worth appreciating. Indeed, at this time all the pests have not yet had time to wake up, and nothing threatens the early harvest of onions. Moreover, early fruiting is possible not only in the southern regions, but also in the conditions of central Russia. However, this variety is unsuitable for growing on greens.
Onion variety "Ellan"
This variety was bred by domestic breeders and is one of the best for growing in central Russia. Although this variety appeared relatively recently, it has been bred for a long time. The aim was to obtain a frost-resistant winter onion that will ripen early and yield a good harvest. This variety is recommended to be sown either in autumn or at the very beginning of spring.For 1 sq. m planted a maximum of 0.2 kg of seed.
Ellan is an ultra-early variety: the harvest ripens in June, and in warm regions - even at the end of May. Unfortunately, its keeping quality is low, but it allows you to get bulbs for salads and pickling even 1.5-2 months before harvesting spring varieties.
In addition to yield, Ellan has a number of additional benefits. It is sweet and delicious. It is also resistant to disease, which also makes growing easier.
The appearance of this variety does not stand out too much. It has straw-yellow bulbs, rounded, slightly flattened. Their average weight is 110 g, although sometimes Ellan grows to 0.5 kg. Not suitable for growing on a feather.
Senshui Yellow onion variety
This variety was bred recently, but it has already been appreciated by gardeners.
This variety was bred in Japan, but at the same time it perfectly adapts to the conditions of the middle zone in Russia or Belarus. It is suitable not only for obtaining a turnip, but also for growing on a feather. For the winter variety, it has a good yield, as well as a pleasant taste and excellent keeping quality. Its bulbs can be stored for up to six months without losing their presentation and taste. Like most winter varieties, it ripens early, already in June or early July.
The Senshui Yellow variety is resistant not only to frost, but also to fungal diseases. In particular, according to experienced site owners, this variety rarely suffers from downy mildew.
As the name implies, its bulbs have yellow scales. It has a high density, which ensures long-term storage. The shape of the bulbs is round or somewhat elongated, the set always resembles a spindle. Good seed has the same shape and size. The choice of onions for sowing should be very careful, often other similar varieties are given out for the Senshui.
Planting and growing
Centurion is an onion with a two-year growing cycle. In the first year, sowing is carried out, in the second, sevok is planted, which gives a crop of full-fledged turnips.
Reference! The hybrid is suitable for both spring and winter planting.
Previously, the seeds are soaked in a light solution of potassium permanganate or warm water with the addition of growth stimulants, then wrapped in a cloth and left for 3 days at room temperature until small shoots appear.
Sevok is chosen no more than 2 cm in diameter... Dry specimens are suitable without damage, rot and unpleasant odor, covered with straw-colored husks. Before planting, onions are disinfected with a solution of copper sulfate (1 tsp of the substance per bucket of water) and heated at a temperature of + 30 ... + 40 ° C.
The land on the site is dug up in advance, cleaned of weeds and plant residues, wood ash, manure or potassium-phosphorus fertilizers are applied to reduce acidity and enrich with nutrients. Peat and sand are added to clay soil.
The hybrid prefers light, fertile soil that is good for moisture, air and has a neutral acidity level.
Timing, scheme and landing rules
For growing seedlings, sowing is carried out directly into open ground or small boxes, containers. This is done in late February - early March, deepening the seeds by no more than 3 cm, keeping a distance of 10 cm between them.
Pre-hardened seedlings are dived into the ground from mid-April to early May, when the ground warms up to at least + 15 ° C at a depth of 12-15 cm.
- In the prepared area, grooves are made up to 4 cm deep, leaving 20-25 cm between them.
- Landing grooves are made in the furrows every 10-15 cm.
- Water the soil abundantly with warm water.
- The seedlings are removed from the containers and placed in the holes.
- They are covered with earth and slightly compacted.
Sevok is planted in spring or before winter, about 2-3 weeks before the first frost.
Planting scheme for onion sets Centurion:
- Furrows are prepared with a depth of 4 cm at a distance of 25–30 cm from each other.
- Water them with warm water.
- The bulbs are planted in the furrows every 10 cm, deepening by 3-4 cm.
- Sprinkle with earth on top, tamp it a little.
Centurion onion develops well at a temperature of + 12 ... + 16 ° C, bright and continuous lighting and abundant watering at the beginning of active growth.
The optimal place for culture is an open sunny area, protected from strong winds and drafts.
Centurion is not planted in the same place more often than 1 time in 3 years. Best predecessors: tomatoes, cucumbers or potatoes.
Nuances of care
Get a bountiful harvest of onions with proper care.
After planting the seedlings in the ground and until the end of June, the culture is watered often and abundantly, about once a week. The approximate water consumption is 8 liters per 1 m2.
With the beginning of the formation of bulbs, irrigation is reduced, and 3 weeks before harvesting, they stop altogether.
Loosening and weeding
After each moistening, or at least once every 10 days, the soil is loosened to avoid the formation of a crust on the surface and to improve the access of oxygen, moisture and nutrients to the bulbs.
They are weeded out as the weed grows, which deprives the culture of nutrients, provokes rotting of vegetables and attracts pests.
- 14 days after germination - mineral fertilizers (ammonium nitrate, superphosphate or potassium chloride diluted in water)
- after 2 weeks - organic matter (1 liter of manure is taken for 5 liters of water, infused for 2-3 weeks, diluted with water 1: 6).
The third feeding is optional. If it is carried out, then complex preparations are used: for example, nitrophoska (2 tablespoons per 10 liters of water).
Important! It is recommended to apply fertilizers in liquid form, as dry plants burn.
Disease and pest control
If the plants are affected by powdery mildew, they cannot be saved. This disease is prevented by prophylactic treatment of plantings with fungicides. They are also used in the development and for the prevention of Alternaria.
Among the pests, the Centurion is attacked by onion moths and flies, against which insecticides are used.
As a preventive measure against planting damage, the rules of crop rotation are observed, and soil moisture is monitored.
One of the most popular ways to ensure onion harvest this year is to use onion seedlings. The centurion is able to form full-fledged turnips as early as 90 days after planting, for which the planting is done in early spring.
Basic rules for success:
- The seedlings must be firm and free from damage. If there is damage on the peel, it is necessary either to remove such seedlings, or to treat the damaged areas with a disinfectant solution (if the areas are small).
- A characteristic feature of healthy bulbs is a homogeneous rustling husk.
- To accelerate the growth processes, it is necessary to warm up the seedlings in a dry, warm place on the eve of planting.
- Shallow grooves are made in the soil, on the bottom of which seedlings are set vertically upwards.
- The grooves in the soil should not completely cover the onions. The outside should remain about 1 - 2 centimeters.
- The distance between the rows should be at least 20 centimeters. This will provide an opportunity for further maintenance and weeding.
- The distance between the bulbs must be at least 8 - 10 centimeters. It can be planted more often if in the future it is planned to thin the onions for greens.
- Abundant watering is necessary only until the end of July, after which it drops sharply.
- Harvesting occurs as the bulbs ripen. This happens unevenly, the state of the aboveground part becomes the main reference point.
- After harvesting, the onions are laid out in a dry, shaded place. Stir the tubers periodically to provide adequate ventilation.

The best varieties of onion sets - which ones?
With the arrival of spring, a hot season begins for gardeners, it is necessary to have time to plant all the vegetables on time. Onions are one of the first to be planted. For planting, sevok is most often used. But, before a novice gardener, the question of choosing varieties of onion sets will certainly arise, because there are a lot of them. And in order to make the right choice and buy the right bow, you need to get acquainted with the characteristics, so as not to miscalculate for sure!
When choosing varieties of onion sets, it is worth focusing on the ripening time, price, and yield. The best in all properties are considered:
Onion Sevok Sturon - the variety is characterized by early ripening, semi-sharp pleasant taste, such a single-nested bulb weighs 90–150 gr. Plants of the Sturon variety sprout together and give a wonderful harvest, but the cultivation of greens from it is not expected. The crop is harvested 1-2 weeks earlier than other varieties. Onions are resistant to various diseases, have a long shelf life
Onion sets Stuttgarter Riesen - when choosing varieties of onion sets for the northwest, attention should be paid to this well-known early maturing vegetable that does not have small bulbs. The bulbs have a dense structure, a flat round shape. One onion can weigh up to 300 grams. Onions of this variety add spice to any dish and significantly replenish the supply of vitamin C in the body. It sprouts well, gives the desired yield and is perfectly stored. But, watering, loosening the soil and removing weeds has not been canceled, otherwise it will be difficult to grow large onions. Onion diseases, unfortunately, also affect this variety, in particular powdery mildew and putrefactive deposits

Technological features of the "Centurion" bulbs during the second year of cultivation
The requirements for site selection and tillage in the second year of cultivation are almost identical to those of the first year. Therefore, we will not repeat ourselves, but proceed directly to preparing the set for planting.
Preparation of planting material
- Sevka bulkhead in order to select undamaged and not decayed specimens.
- Selected bulbs are heated outside under a canopy or other cover for 3-4 days.
- Bulbs are selected 1-3 cm in diameter.
- The sevok is disinfected by immersion for 10 minutes in a solution of copper sulfate (10 g of the drug per 10 liters of water).
Sevka planting is started when the ground at a depth of 8-10 cm warms up to + 9 degrees Celsius. Sevka planting is carried out as follows:
- Planting furrows are prepared with a depth of 6-8 cm.
- The distance between adjacent furrows should be 10-12 cm.
- For 1 running meter of the planting furrow, 40-50 g of rotted manure and 10 g of wood ash are introduced.
- Sevok is placed in the prepared furrows with a distance of 8-9 cm from each other.
- The furrows are covered with earth and tamped a little.
- Weeding. Carried out throughout the entire growing period. The depth of cultivation is 2-3 cm. The main task of weeding is to suppress and, if possible, remove weeds from the area where this variety is grown.
- Watering. Plants of the "Centurion" variety respond well to systematic watering. For this variety, one watering per week is sufficient. At least 10 liters should be consumed per 1 m2. water.
- Top dressing. You need to carry out at least two dressings:
- The first feeding is carried out three weeks after planting the seedlings. For this, ammonium nitrate is very well suited, which is scattered over the soil surface and immediately watered. The fertilizer application rate is 20-25 g per 1 m2.
The second feeding should be done in two weeks. At that time, fertilizers such as Energen Aqua and Potassium Humate are best absorbed by onion plants. For this, plants are sprayed with a solution of 20 ml. 10 liters. water in the evening.
- Pest control. Variety "Centurion" can be severely damaged by onion fly larvae. The end of June - beginning of July is considered a particularly dangerous period. At this time, the hatched larvae penetrate into the middle of the leaves of the bulbs and very strongly oppress the plants, leading to a slowdown in their growth and a significant decrease in yield. Control measures: In case of mass summer of adults during the month of May, it is necessary to spray the onions with insecticides "Commander" and "BI-58".
The Centurion variety is harvested in late July - early August. When the leaves are lodged, the bulbs are neatly pulled out and merged into heaps. Cleaning needs to be done on a tight schedule. The harvested crop is transferred under some kind of cover and spread out in a layer of no more than 8-10 cm. After 2-3 days, the roots and withered leaves are cut off from the bulbs dried in this way. From 1 m2 you can get 5-6 kg. beautiful bulbs of this variety.
The harvested crop is stored in wooden boxes, baskets and nets. The air temperature in the storage should be –1 -3 degrees Celsius. Relative air humidity 55-70%.
