Description and characteristics of this variety are given in this review.

Onion Sturon is considered one of the best results of the work of Dutch breeders. Its predecessor was a well-known onion variety called Stuttgarter Riesen.

The variety of onions Sturon has medium ripening periods, due to which ripe harvest can be obtained in 100-110 days after the first shoots. This indicator allows you to grow a variety in the central and northern part of the country. You must also indicate that the plant is not afraid of frost and tolerates even the most severe winters.

Large bulbs are formed only in the second year, in the first season you can grow good planting material. If you properly care for onions, then from one hectare you can collect up to 35 tons of crop. This factor is attractive for entrepreneurs who grow spicy vegetables for sale.

To the positive qualities of the variety include the shelf life of the fruit. If you comply with all the necessary conditions, the crop will retain its freshness for 8 months.

The interior is a few juicy layers, painted in a greenish color. The taste of the pulp is bitter-sharp, and the aroma is tart and quite sharp.

Such onions can be used for fresh consumption, preservation and heat treatment.

Variety Sturon is not influenced by most common diseases and pests.

Virtues

Sturon bulbs are quite large, up to 200 grams

  • Bow Sturon has wonderful taste and aroma,
  • The plant is suitable for growing in temperate and northern latitudes,
  • One hectare of land can be harvested to 35 tons of crop,
  • One bulb reaches in weight 210 grams,
  • Under all conditions, this grade can keep its freshness for 8 months.

disadvantages

  • When growing seed from seed, there is a fairly high risk of obtaining planting material of small size,
  • Variety poorly resistant to false powdery mildew and onion mosaic,
  • For a rich harvest, the plant must be grown exclusively on loamy or sandy soils.

In order to get a good harvest you need to choose the right planting material. Onion sets can be purchased at a specialty store or independently grown from seed. It should be large (with a diameter of at least 2 centimeters) and have a smooth surface. Do not plant sevok with the following defects:

  • presence of signs rotting,
  • any kind of mechanical damage,
  • a large number of moisture in the bulbs,
  • the signs disease effects or pests
  • presence of green arrows or small roots.

Planting sevka produced in early spring. In order to avoid the formation of various diseases and other problems, the bulbs are stored at a certain temperature, which consists of several stages:

  1. First week onions stored at a temperature of 20-25 degrees,
  2. Second week at a temperature of 30 degrees
  3. In the third week the temperature is raised to 35 degrees
  4. Then sevok for 8-12 hours removed in a place with a temperature of 40 degrees,
  5. The remaining time before planting the bulbs, their stored in a dry place with a temperature of 18-20 degrees. During this process it is very important not to neglect airing.

In the event that the diameter of the set does not exceed 1 centimeter, it is planted before winter, several weeks before the onset of frost. In this case, the bulbs can grow and root before the onset of spring.

When spring planting sev adhere to the following rules:

  1. Sturon recommended grow on slightly acidic, loamy or sandy soils,
  2. In the late fall into the ground for digging make humus and rotted manure, and just before planting they add mineral fertilizers,
  3. For the proper preparation of planting material, cut the neck of the bulbs so as not to damage the sprouts,

Sorting and trimming onions

  1. A few days before landing the soil is cleared of weeds, loosened and form lines, at a distance of 20 centimeters from each other,
  2. Sevok deepen into the ground by 2-3.5 centimeters, the distance between the individual bulbs should be 10-15 centimeters.

Independent cultivation of onion sets from seeds is a fairly simple exercise, during which it is very important to take into account the basic rules. First of all it is necessary to observe the landing terms.. In the southern regions, seeds are placed in the ground in spring (late March), and in the central and northern latitudes in the first weeks of April.

Specific planting dates will depend on the readiness of the soil, it should be thawed by 5-6 centimeters.

Soil preparation should begin in the autumn, the following fertilizers are applied to 1 square meter of land for digging:

  • half a bucket compost,
  • 1 cup wood ash,
  • 1 tablespoon phosphate fertilizers,
  • 1 tablespoon superphosphate.

2-3 days before planting, the soil is plowed and form the beds, and then compacted and covered with black film.

Seeds also need to be prepared, for this they are soaked for 4-6 hours in manganese or aloe juice. After that, they are wrapped in a damp cloth and stored in a dark place for 2 days. It is very important to prevent the fabric from drying out.

Soaking seeds onion Sturon before planting

Sowing seeds in the ridge produced by the following algorithm:

  1. To start ridges watered with warm water and form furrows, at a distance of 20 centimeters from each other,

Furrows for sowing onion seeds

  1. The seeds are laid out on the surface. so that the distance between them is equal to 10 centimeters,

Sowing onion seeds on ribbon

  1. Then seeds sprinkled with a thin layer of soil and carefully watered. It is advisable to mulch the planting with peat or compost.

Caring for onion varieties Sturon is divided into two components, because the cultivation of seed and full-grown fruits are significantly different from each other. In the first year of plant life, when the main goal of the gardener is to obtain a quality seed, the onions are cared for as follows:

  1. As soon as the first shoots appear, landing must be thinned. This procedure will help to form a large sevok,

  1. Land need regularly loosen,
  2. Watering is carried out once in 7-10 daysorganic or mineral fertilizers are added to the water,
  3. When sprouts reach a height equal to 2 centimeters all work should be stopped.

Then the gardener should wait for the moment of complete wilting of greenery and softening of the neck. In this case, the onions can be dug, dried and prepared for storage.

When growing fruits for eating, perform the following steps:

  1. Bow Sturon must be abundantly watered, preventing the drying of the soil. In one procedure, 12-15 liters of water are consumed per square meter of soil,
  2. After the appearance of the first young landing feathers fertilize with nitrogen fertilizersfor example, urea,

To compensate for the lack of nitrogen in the soil on which the onions grow, it can be watered with urea or with a solution of slurry

  1. Also needed regularly loosen the ground and clean it of weeds.

When harvesting, you can not wait for the moment when the leaves are completely dry. In this case, the roots may begin to rot.

Although the onion variety Sturon has good immunity to many diseases, you can see signs of the following ailments on it.:

  1. Downy mildew manifested in the form of characteristic spots on the leaves of the plant, which gradually grow. The fungus is localized in the bulbs and can cause the death of the plant. Downy mildew spreads very quickly, so infected plants should be removed immediately. The remaining landings are treated with Fitosporin-m and Phytoplus. From such a disease is very difficult to get rid of, so do not neglect the prevention, which includes pre-treatment of planting material,
  2. Neck rot may occur during storage of the crop. Control measures will be the timely removal of the affected bulbs,
  3. Onion Mosaic - initially, this virus can be seen by the formation of yellow spots on the leaves. Then the aboveground part gradually dies off, and the fruits become very small and poorly stored. It is almost impossible to fight this disease,
  4. As for pests, Sturon's bow is often damaged by a nematode.. The drug Mercaptophos and Phosphamide helps in the fight against worms.

Downy mildew Onion nematode Neck rot Mosaic onions

Sturon onions are well suited for cultivation in the central and northern region. Its frost resistance and average ripening period allows to get a rich harvest of tasty fruits even in adverse weather conditions.

Onion Sturon variety description reviews. Features of planting and care

Without onions it is impossible to imagine the preparation of most dishes. In addition to the savory spicy taste, onions are also a natural phytoncide, which actively fights pathogenic microflora and protects the body from colds.

This variety of onions is bred by Dutch breeders. If you want to know what is onion Sturon, then carefully read the description of the variety and see also the reviews.

Surely, this information will be useful for you.

Description of onion "Sturon"

Bow Sturon in many respects surpasses his fellows. In terms of ripening is a medium early variety. 105 - 110 days pass from the moment of germination to ripening of the bulb.

Holland is notable for its harsh climatic conditions, and breeders specially bred a frost-resistant variety. They coped with their task, Sturon tolerates frost well, which, of course, is a valuable property.

In addition, onion Sturon has a consistently high performance - at least 30 - 40 tons per hectare.

Onion Sturon is highly resistant to pests and diseases characteristic of this culture. This quality makes it possible not to use toxic chemicals and chemical fertilizers in cultivation.

Planting onion "Sturon"

Characteristics of onion Sturon may seem good to you.However, a rich harvest and healthy fruits can be obtained only if you make the right planting and make care competent. But you can see some tips on growing this crop.

Choose a seed.

To get a good harvest, you must follow the recommendations for growing onions Sturon. It can be grown as a one-and two-year culture, but it should be noted that large-sized fruits can be obtained only in the second year.

For maximum yield, you should choose sandy or loamy, fertile, loose soil. If the soil is heavy and with high acidity, the onions will grow much worse.

Sevok for planting onions can be bought in a specialty store, or grow from seed yourself.
In both cases, it is important to choose the right set.

Bulbs are carefully sorted out, they should be smooth, strong, fairly dry, the most optimal size - 1.5 - 2 cm. Copies touched by rot, with signs of disease or damage for planting will not work. Such material will not germinate and simply rot.

If green arrows or roots appeared on the bulbs, it means that they have left the state of rest. This material for planting is also not suitable, it is best used for growing greens.

In case you bought material for planting in the fall, it needs to create appropriate conditions for storage. Many vegetable growers, for reliability, carry out a number of procedures in order to prevent bulbs from having neck rot and downy mildew.

Processing consists of warming the onions with an increase in temperature in four stages. The first three stages last for one week: in the first temperature should be 20 - 25 degrees, in the second - 30 degrees, in the third - 35 degrees.

At the final stage, the bulbs are kept at a temperature of 40-42 degrees for 8 to 12 hours.

After that, the bulbs can be sent to storage. The room for this purpose should be dry, well ventilated, with a temperature of 18 to 20 degrees and a humidity of no more than 60 to 70%. You can store on shelves, in lattice boxes or in nets.

Also sevka for cultivation can be grown from seeds independently. In this case, to obtain suitable for planting bulbs with high productivity, you also need to follow certain rules.

The soil for sowing must be prepared in autumn. For planting choose a dry, well-lit place. Observe crop rotation, good predecessors for Sturon are cucumbers, radishes or cabbage. You should take only last year's seeds, while if you got them yourself, it is better to keep them in a weak solution of manganese or aloe juice.

In the spring, as soon as the earth thaws on 5 - 6 cm, you can plant seeds. As a rule, in the middle lane it happens in the twenties of April. However, if the weather allows, landing can be made in early April. At the same time, you should not be afraid of late frosts - this variety perfectly withstands temperature reduction, seedlings - up to -3, and bulbs - up to -4 degrees.

Soil preparation.

You, probably, have already understood that onion Sturon requires a certain cultivation. And with these rules we are familiar, just today.

In the fall: the land must be properly dug up and fed. The feed rate per square meter is as follows: 0.5 compost buckets, 1 cup of wood ash, and a tablespoon of nitroammofoski and superphosphate fertilizer.

In the spring: on the eve of planting or a little earlier, the plot is well loosened and form the beds, then the ground should be compacted and covered with black film.

Just before planting: if you plant unsprouted, dry seeds, you first need to water the beds with hot water, form small grooves and water them again. If the seeds have slipped, this can not be done.

Seeds can be planted in two ways: in rows or ribbon.In the first method, rows are made at a site at a distance of 10 cm, into which seeds are sown. When planting with a ribbon, wide beds are made at a distance of 20 cm, seeds are sown randomly, approximately 10 g per square meter.

Whatever method you choose, the next steps are the same - you need to lightly sprinkle the seeds, compact the soil, cover with compost or peat, and pour water from the watering can.

Care of shoots onion sets.

After seed germination, they need to thin out. This will give the shoots the necessary freedom, and the seta will grow large.

In the future, care will be in loosening the soil, regular, but not abundant irrigation, fertilizing with minerals and organic matter. When the fruit reaches the size of 1.5-2 cm, these procedures must be stopped.

When the green arrows fade and the neck of the bulbs soften a bit, you can dig up the fruit. After drying, they can be stored for the next seeding.

If your onion sets are too small - up to 1 cm in diameter, it is almost impossible to store it, it is easier to plant it before winter. In this case, he manages to feed on the spring moisture, gain strength, and you can hope to get a large onion. On the feather such sevok also goes earlier.

Onion planting "Sturon" for the second year

Planting bulbs can be made in late autumn and spring. In the fall, they do it 2–3 weeks before the frost. So sevok will have time to take root, but the shoots are still not allowed. This will create conditions for a good wintering. In the spring, Sturon is planted approximately 2 weeks after frost.

It is necessary to carry out preparatory activities: towards the end of autumn organic fertilizing is carried out, and immediately before planting - mineral. Before planting, the earth should be dug up and made rows with a distance of 20 cm between them. In the selected bulbs carefully, so as not to damage the sprouts, cut the neck.

Sevok planted with a distance between the bulbs of not less than 10 cm, to a depth of about 3 cm.

Onion care "Sturon"

What description of the variety has onion Sturon? It is worth looking at the photo and read the information that is available here. Of course, every summer resident and gardener should know some rules for caring for a culture that are within the scope of this publication. So, after sowing, the beds mulch with a layer of about 1 cm. When the first sprouts appear, they mulch the rows between 3 and 4 cm.

Watering should be done as follows. The first is 5 days after sowing. Watering rate - 5 - 6 buckets per 10 sq. M. Watering should be careful, it is better to do it out of the watering can through a sprinkler.

The second watering is done in two weeks, during the period of the formation and growth of leaves, when plants especially need moisture. The norm is the same. Subsequent watering should be regular, so that the plants do not have a lack of moisture. You can water both through the sprinkler and in the furrow.

Approximately a month before cleaning, watering should be stopped, because excess moisture retards the ripening of the bulbs.

After the rain and every watering the soil should be loosened. Loosening should be shallow, because onion roots are located close to the soil surface. You must also ensure that your onions are not overgrown with weeds. Weeding is best done after rain or watering when the soil is wet. Weeds are removed much easier and less likely to damage the roots of the onion itself.

The first dressing produced in the phase of 1-2 sheets. On 10 l of water take 15 g of nitrogen and 20 g of potash fertilizers.

At a distance of 5 cm from the rows of onions, furrows are made into which the solution is poured at the rate of 1 bucket per 10–15 m length of the furrows. The second feeding is needed during the formation of the bulbs.

At 10 liters of water take 40 g of phosphate and potash fertilizers. Norm - a bucket on a 10 m furrow length. When the feather starts to turn yellow, it's time to harvest.

We hope our article will be useful to you, and the harvest will make you happy.

The Sturon variety has round-ellipsoid bulbs with a very narrow, quickly drying neck and a small bottom. The bulb itself has a golden hue with longitudinal stripes of a light brown color. The scales inside are white, with a faint green tint, juicy and dense.

Onions of a grade of Sturon with sowing material

The variety is medium early, the bulbs can mature almost 105-110 days after the appearance of the first shoots. Thanks to this characteristic, it is possible to grow Sturon onions in temperate and northern climatic zones.

The main advantages of the variety

  • The bulbs can vary in size, reaching a weight of 170-200 grams.
  • The variety has a high and stable yield, reaching 35 tons per hectare. Commercial availability is very good, and onions are kept remarkably for up to 8 months. These qualities make it suitable for commercial cultivation.
  • Bow Sturon almost no arrows.
  • The grade possesses high flavoring qualities and pronounced smell.
  • Finally, the Sturon onion variety is not susceptible to major diseases and pests. This allows you to grow it without using special means of protection.

Features of growing

The variety of onion Sturon is possible to grow, both in one-year, and in two-year culture. But to get really large bulbs, it is necessary to grow in two stages: in the first year - sowing seeds of chernushki and getting onion sets. And only in the second year when planting seedlings receive large commodity bulbs.

Onion Seeds - Black

This variety can also be used for growing on a green feather. It is possible to plant it in late autumn or to breed greenery in winter in greenhouse conditions and even at home on window sills.

Sowing seeds for sevka

Seeds for planting need to take only fresh, as the onion loses germination very quickly. Before sowing, the seeds are disinfected in a pink solution of potassium permanganate, then soaked for a few days in a mixture of aloe juice with water to stimulate germination. After a little drying, they can be sown.

The dates are chosen by the earliest, literally waiting for only the thawing of the earth by 5-6 cm. The bow is not afraid of returning frosts, since the shoots are kept up to -4 ° C. The optimal period for the middle band usually comes in the second half of April, but sometimes weather conditions allow you to sow onions at the beginning of the month.

The best harvest will turn out on sandy soils, but easily loamy will also work. Onion seeds are sown in rows, to a depth of 1-1.5 cm. Approximately 10 g of seeds are consumed per square meter.

After germination (after 10–20 days), seedlings should be watered regularly, since in the first weeks of growth they are very sensitive to drying out of the soil. When the seedlings grow a little, they must be thinned out, leaving 3-4 cm between the bulbs.

Further care is reduced to regular watering, feeding and weeding. When the onions reached 1.5-2 cm watering should stop, wait for the leaves to wither, dig, dry and put in storage.

Planting sevka

Bulbs less than 1 cm in size are recommended to be planted before winter, in which case they will not only be preserved, but will be able to catch up with their brethren in the spring. In this case, try to meet the landing in time when the frost will be 20-30 days. During this time, the bulbs should have time to form the roots, but not to ascend.

In the spring of sevka planted about the same time as the chernushka. Planting depth is about 3 cm. The distance between the plants is made larger - about 12 cm per large size of the grown onion. The distance between the rows is 18-20 cm.

Onion Growth Sturon

For the formation of large onion varieties Sturon onions require abundant and fairly frequent watering. Top dressing is obligatory, but it should not be abused with nitrogen fertilizers, because of the tendency of onions to accumulate nitrates. It is also important to keep the soil clean and to carefully loosen it constantly.

Since July, watering is gradually stopped, it is necessary to give the bulb time to form well. In no case is the green feather cut off; let it shrink. This is one of the main conditions for the formation of large bulbs. Crop is usually harvested in August, after the leaves fall and the neck of the bulbs dries.

Onion Sturon: variety description, planting and care

Among the many varieties of onions, the deserved popularity belongs to the hybrid of the Dutch selection - the onion Sturon, the description of the planting variety and caring for it demonstrate its excellent taste, its ability to be stored for a long time and the simple cultivation technique. The bulbs of the highest quality can be used for consumption in fresh and processed form, for storage for the winter.

Agrotechnics of growing Sturon

Sturon is grown as a one- and two-year culture. Onions can be cultivated not only in the open air, it is planted in greenhouses for the winter to get greenery. As a result of annual cultivation, small onions are produced; Sturon reaches large sizes only in the second year.

Onion sets Sturon prefers sandy, fertile soil. It is in this area, with a two-year cultivation method, that the maximum yield and size of heads is achieved.

In most cases, sowing is done in early spring. For the middle band, April is considered the most suitable for seeding.

For better germination, it is recommended to soak the chernushka for several hours, and then wrap the seeds in a damp cloth and leave for 2 days. The soil on the bed is pre-cooked, furrows are made at a distance of 10 cm.

The seeds are covered on top with peat or humus, the layer of which should be 1.5-2 cm.

After germination, onions must be thinned to obtain a sufficiently large onion sets.

Care of crops consists in regular loosening of the soil, frequent, but not too abundant watering, fertilizing with organic or mineral fertilizers.

When the onions reach a size of 1-2.5 cm, fertilizing, watering and loosening the soil is stopped. Having waited for wilting of greens and softening of a neck of sevka, it is dug out and dried.

For winter, the collected onions are laid out in small bags of several kilograms or in boxes with a layer up to 8 cm. The room in which the planting material will be stored must be well ventilated, the optimum temperature is 15-19 ° C.

Growing Sturon for the second year

Sevok can be planted in the winter or spring. Before planting, be sure to calibrate the bulbs, rejecting damaged specimens. Winter planting takes place 2-3 weeks before frost.

As a rule, this is the end of September and the beginning of October. Such terms allow the onions to take root, but they do not germinate and tolerate the winter well.

Spring planting is carried out after the end of frost in the period of April-May.

Before planting, a sevok is inspected, carefully cutting off a dry neck, trying not to damage the sprout. Onions can be soaked in water at room temperature for several hours to accelerate germination.It will protect against soaking for 5 minutes in a weak solution of copper sulfate at the rate of a teaspoon per 10 liters of water. After this procedure, sevok washed under running water and planted.

The best for onions are sandy, loamy soils. On acidic and heavy clay soils culture will grow worse. The soil in the beds should be carefully prepared, fertilized.

Mineral fertilizers are applied before planting, and organic fertilizers are recommended for the winter. The distance between the rows is 20 cm, and between the bulbs in the rows - 10 cm.

A shallow planting of seed bulbs is undesirable, they are buried by about 3 cm.

To form large bulbs and build up the pen, Sturon needs regular watering, which ceases 4 weeks before harvest. During the growth period, the crop requires regular weeding, loosening the soil (5-6 times), feeding after germination and repeated after 6 weeks. Another requirement is not to tear off the pen.

This will affect the size of the bulbs. Varietal characteristics of Sturon include increased resistance to diseases and pests. However, having noticed their signs, it is better to process the plantings with a special agent, by dissolving a teaspoon of vitriol in a bucket of water (10 l). At the end of August green onions should dry out and lie flat on the ground.

The time to harvest has come.

For this purpose, podzimnyaya planting of onion sets is done, it is also possible to grow greenery in winter in the conditions of a greenhouse or at home in pots.

The first way - getting onion sets

Onions seeding "Sturon" produced in the early stages, in the middle lane - in April. So get onion sets of very modest sizes. As a rule, it is used for growing large specimens in the coming year.

For planting are selected 2-centimeter onion-sets, intact and well preserved after maturation.

In the period from the end of April to the beginning of May, when the threat of frost on the soil has passed, the bulbs are planted on a piece of land with fertile, preferably sandy loam, soil.

At the same time, the optimum planting depth of planting material is 1.5 cm. Sturon onions are traditionally planted according to the following pattern: 20x10 cm.

A winter planting of onions is possible, which is desirable to be held in early October two to three weeks before the onset of sustainably cold weather. During this time, the bulbs form the roots, but the arrows do not have time to give.

Caring for a variety of onion "Sturon" provides abundant and fairly frequent watering for the full growth of foliage and growth heads. In addition, weeding should be carried out for weeding and regular loosening.

With the advent of onion feathers, it is possible to water the garden beds with a culture of urea.

As indicated above, onion Sturon practically does not suffer from diseases and parasites, but if you notice signs of the disease, then it is necessary to process the planting with a solution of 5 liters of water and 3 mg of copper sulphate (approximately half a spoon).

Harvesting culture carried out when the neck of the plant dries. This period in the northern and middle latitudes falls on the end of August - the beginning of September.

Bow Sturon - characteristics, features of planting, care, harvesting and storage

Onion Sturon - a well-known variety, bred by Dutch breeders from simple onions. It enjoys wide popularity, despite the fact that it is a 2-year-old crop and requires a rather large amount of time, effort and energy to produce a crop.

Onion Sturon belongs to the hybrid varieties, has an ellipsoidal shape, thanks to which the culture is in demand among housewives. The size of the fruit is quite small, reaching 150-200 g.

The onion neck is thin, the upper scales are yellow-brown in color, dense, the inner ones are white with a greenish tint. Ideal conditions for growing vegetables are warm and temperate climatic zones.

Vegetable belongs to the middle-early varieties, ripens in 100-115 days.

Sort Sturon is very popular among different categories of the population due to its positive properties:

  1. Great taste and spicy spicy aroma. Because of this, it is used for various purposes - in the preparation of the first or second course, added to salads, used for preservation.
  2. High yield. On fertile soil and with proper care you can get a good harvest - up to 30-35 tons of onions per hectare, which is pretty good indicators.
  3. Long shelf life. If the optimum storage conditions are observed (temperature + 12 ... + 150С, air humidity 70-80%), the fruits retain their taste and do not deteriorate for 6-8 months.

  5. There is no "bolting". From each planted sevka grows a large onion.

Soil features

Bow Sturon grows best on sandy and loamy soils. When planted in sour and clay soil, the vegetable grows much worse, which has an adverse effect on obtaining a good harvest.

Care should be taken when choosing a site. It should be dry and sunny, located exactly or not a small elevation. This will prevent the occurrence of increased soil moisture after snow melting (during autumn planting) or prolonged rains.

An important role in obtaining a good harvest is what crops were located on this piece of land before it. Onions Sturon grows well after legumes, tomatoes, potatoes, etc.

The important role played by the observance of the rules of agricultural engineering. The bed should be prepared a few weeks before the expected planting of seeds (chernushki) or seeds (one-year bulbs), so that the earth is a little bit sown.

First, the ground must be dug, remove weeds and other debris. When the soil is infected with worms or other pests, it must be disinfected.

To do this, the land must be treated with extracts of tobacco, salt or copper sulphate.

We must not forget about feeding. Organic fertilizer should be used, and in its absence - superphosphate, ash, potassium salt.

Enriching the soil with nutrients will help provide all the necessary components for the rapid growth of planting material.

Onions Sturon is grown by two methods. With the help of seeds or sevka. Each of them has its advantages and disadvantages.

The use of seeds implies a longer period of cultivation, since in the first year of agrotechnology, only sevok can be obtained, and large bulbs - already the next season.

However, at the same time, a person completely goes through all the stages of agrotechnology and is confident in the quality of planting material for the production of the finished vegetable.

Many farmers prefer to buy selected and processed crops to get a full harvest at the end of summer.

Planting seeding is carried out in a well-heated soil, when there is no risk of frost. Depending on the region and climatic conditions, this period may differ slightly - the end of April or the beginning of May.

There is another option of planting - in the fall, 2-3 weeks before the onset of sustained frost or cold weather. During this period, the bulbs will have time to take root, but the arrows will not yet grow and freeze. The advantage of the method is that in spring, upon the occurrence of favorable climatic conditions, the sevok will immediately grow.

For cultivation should be selected small onions with a diameter of about 1-2 cm, with no signs of rotting and other damage. The optimum depth of planting is 1.5 cm, between sevka in the row should be at least 10 cm. The standard row spacing is 20 cm.

To stimulate the growth of bulbs, planting material must be removed from the cellar in 3-4 days to warm the bulbs and cut off the dry neck. Before planting the culture can be soaked in warm water for 2-3 hours, this will ensure good germination.

Seeds or chernushka sown in the ground in late March or early April.

In order to improve the yield, planting material needs to be germinated - put in a glass jar and pour warm water with the addition of a growth stimulator (Epin, etc.).

After a few hours, the seeds are laid out on a piece of cotton fabric folded in several layers and left in a warm place for 2-3 days. It is necessary to ensure that the material remains wet all the time.

Chernushka sown in the ground to a depth of 1.5-2 cm, the distance between the seeds should be about 8-10 cm If sown thickly, plants can be thinned out when several leaves appear above the ground surface.

Regardless of what material was used for planting, to get a good harvest of Sturon onions, you should strictly follow all the rules of farming. These include:

  1. Loosening the soil and cleaning the weeds. Provide access to oxygen to the roots, improve the flow of moisture and other nutrients to the plants.
  2. Regular watering. The soil should be moistened regularly, but it should not allow the accumulation of excessive moisture. This threatens to rot bulbs, which will lead to a significant loss of harvest.
  3. Making feedings. For enhanced growth and development of seed and onion seeds Sturon requires a sufficient amount of minerals. In the absence of them in the ground, you need to take care of regular fertilizer application, especially during the appearance of the first feathers. Good results are shown by the use of chicken manure or a combination of urea with mullein.

Nitrogen-containing feedings should be avoided, onions absorb nitrates quickly.

A characteristic feature of Sturon's onion farming is the ban on cutting off the feather. This will give the opportunity to receive large fruits.

Cleaning and storage

Sturon onion harvesting should be carried out only after the green part of the plant is completely dry and the neck is softened. The main sign of ripeness is determined very easily - all feathers fall on the ground.

Only by adhering to these rules, it is possible to ensure good long-term storage of the vegetable, otherwise the culture will begin to deteriorate and rot.

After harvesting, the onions should dry well and ventilate so that no moisture is left in it. It is strictly prohibited to place it in the basement, shed and other premises intended for the storage of vegetables right from the garden.

The bulbs should be sifted, cut off the roots and the dry upper part of the culture, and separate immature or damaged specimens. They must be used for cooking or other purposes as quickly as possible, since they will not be stored for a long time.

For convenience, the crop should be placed in wooden or plastic boxes with holes. This will keep good ventilation and at the same time provide an opportunity to save space. The maximum height of the bulbs in the container should not exceed 8-10 cm.

The optimal storage conditions are a cool room in which the air temperature is no higher than + 13 ... + 150C.

Despite all the precautions, the vegetables must periodically be sorted out in order to extract damaged bulbs from the mass and to prevent the spread of rot in other specimens.

Onions Sturon - an excellent option for growing by farmers and gardeners. Excellent taste qualities together with unpretentiousness of the culture, resistance to adverse environmental conditions and pests provide huge advantages over other varieties of onions. To get a good harvest, you should follow the rules of agrotechnology, take care of plants in a timely manner and apply fertilizer.

Also read about the variety of onion sets Turbo, which has early maturity and frost resistance.

Characteristics of a variety

Maturation term "Sturon" - medium: It should take about 100 days after the appearance of the first shoots before it ripens. This variety is also popular for its taste qualities: a pleasant bitter-spicy taste and a slightly tart flavor. Such onions are actively used both for preservation, and for salads and other dishes.

Differences and advantages over other varieties

In the description of the onion-sevka varieties "Sturon" it should be noted positive qualities thanks to which it attracts more and more gardeners and industrialists:

  1. Due to the average maturity of Sturon, it is well cultivated in the temperate and northern climatic zones.
  2. Good yield: up to 35 tons per hectare in the right soil (the best choice is sandy or loamy loose soil).
  3. Quite large bulbs that sprout when grown for two years.
  4. Quality crop that is well preserved (up to 8 months). Thanks to this Sturon is widely used for commercial purposes.
  5. Resistant to frost, therefore, is considered one of the best varieties of onions for storage for the winter.
  6. Resistance to diseases that affect many other plants of the same type, and pests of different species, which allows Sturon to be grown without treatment with pesticides.

Not only these qualities distinguish this variety from others, Sturon bulbs also have healing properties due to:

  • the content of a large number of micro-and macronutrients, including calcium, phosphorus, magnesium, sodium, potassium, iron, zinc, fluorine, copper, selenium,
  • 11 amino acid substitutes in onion heads,
  • vitamins A, C, D, E and C, PP, K and group B contained in bulbs

Features agrotechnology growing

The popularity and prevalence of onion "Sturon" among farmers and gardeners necessitates not only a detailed description of the variety, but also how the planting takes place, what are the ways of growing onions and what should be caring for them. “Sturon” can be grown for one or two years, but large heads grow only in the second year.

In order to get green leaves in the winter off-season, plant podzimnuyu onion planting using simple designs of greenhouses or ordinary pots to grow it on the windowsill in the house. It is possible to cultivate Sturon by purchasing sevok in the store (this is done in order to get a rich harvest in the very first year) or by growing planting material yourself.

The hard work is to choose the right sets for planting: they should be about 2 cm in size and have a flat surface. You can not plant bulbs:

  • even a bit rotten or damaged,
  • wet
  • with signs of disease or exposure to parasites,
  • bulbs that came out of dormancy (with green arrows and small roots).
Having purchased the material for the first landing in the autumn, it is necessary to ensure proper storage conditions. To avoid landing material diseases, it stored at a certain temperature, which varies depending on the following steps:
  • First stage: week, temperature - +20. +25 ° C.
  • The second stage: week, temperature - +30 ° C.
  • The third stage: week, temperature - +35 ° C.
  • The fourth stage: 8-12 hours, temperature - +40 ° C.
  • The rest of the time the bulbs should be stored in a dry place with a temperature of +18. +20 ° C, regularly airing it.

Seed dates

It is not difficult to grow onion sets of this variety independently from seeds, but you need to know a few rules that will help efficient germination and obtaining a good harvest. This is, firstly, the observance of the correct timing of sowing seeds. As a rule, they are planted as early as possible - in the first or second week of April, when the earth thaws by 5-6 cm. In southern latitudes, it can be sown at the end of March.

Planting seeds

It is necessary to prepare the plot and plant the seeds, following the sequence of the following steps:

  1. In the fall, dig up the soil and fertilize the compost (half a bucket per square meter), wood ash (1 cup per square meter), phosphate fertilizer (1 tablespoon per square meter) and nitroammophos, azofosc (1 tablespoon per square meter).
  2. When spring comes, 2-3 days before planting, plow the plot and make the beds.
  3. Seal the soil and cover with black film.
  4. Soak the seeds for several hours in a manganese solution, aloe juice or warm water, wrap in a damp cloth and leave for two days, ensuring that the cloth remains moist.
  5. Before planting, water the beds with warm water, form furrows on them for sowing seeds, and water again.
  6. Plant seeds in rows (small, with a distance between each - 10 cm) or tape (wide, with a distance of up to 20 cm).
  7. Sprinkle the seeds with a small layer of earth.
  8. Condense the soil, covered with peat or compost, pour a little water.

Care features

After planting onions sets and requires proper care. Seeds, when they germinate, but have not yet reached 2 cm in height, must be carefully thinned in order to obtain large sevok. Then it is important to regularly loosen and not too often water the soil, adding organic and mineral fertilizers.

When the shoots reach the specified height, these procedures must be stopped. Then it remains to wait until the greens wither, the neck of the bulbs will become softer and the bulbs can be dug. After digging - dry the heads.

Growing for the second year

If, after the first cultivation, the seedlings come out too small (up to 1 cm in diameter), it will be almost impossible to keep it for a long time, so you need to plant it before winter (a few weeks before frost). Frosts to “Sturon” are not terrible, and during this time the bulbs will have time to grow and gain strength due to spring moisture, they will take root, but they will not sprout yet.

In the event that the bulbs have acquired the desired shape, You can plant them in the second year at the beginning of spring by following these steps:

  1. Feed the soil with organic fertilizers at the end of autumn and add mineral fertilizers before planting.
  2. A few days before planting, loosen the soil and form lines, keeping a distance of 20 cm between them.
  3. After selecting the appropriate bulbs, cut off their neck so that the shoots are not damaged.
  4. Close the heads to a depth of 2-3.5 cm, so that the bulbs are up to 2 cm of soil above the shoulders, keeping a distance of 9-13 cm between the sets.
When Sturon is planted, it should be watered abundantly, especially in spring (3-4 irrigations before the beginning of June with water consumption from 12 to 15 liters per square meter). After the first young feathers appear, it is necessary to fertilize the sowing with chicken manure or cow and urea.

To achieve the desired results of planting this variety of onions, we should regularly weed and loosen the top layer of soil, timely remove weeds near the shoots. As a rule, the crop can be harvested at the end of August, when the plant's neck dries, leaves fall, and the onions turn yellow. But do not wait until the leaves are completely dry, because the bulbs can start to rot.

Bow "Sturon" continues to gain popularity due to its resistance to diseases and parasites, a variety of useful properties and a good effect on the human body. You can grow this variety for one or two years, but you can only count on a rich harvest and large bulbs in the second year. This variety requires standard care and fertilizer.

Description and main characteristics of the variety

Sturon is one of the most popular hybrids of onions. This mid-season species, which ripens on the 100-115th day after the emergence of sprouts, was first bred in Holland. It is grown by farms mainly in countries with a warm climate, but the hybrid is frost resistant. Dutch onions attract gardeners primarily by high yields (25 tons per hectare of land), long shelf life and ease of agrotechnical care.

Vegetable culture is resistant to fungal diseases and pests, which reduces the cost of purchasing fertilizers and chemicals.

Onion sets Sturon is grown on a large scale, since after harvesting its taste and appearance do not change for 7-8 months.

Based on the experience of farmers, a yield of more than 20 tons per hectare can be obtained on friable sandy soils.

The characteristics of the characteristics of the Sturon variety include the weight of ripe fruits - 200 g. Such bulbs become round in the second year of cultivation. Vegetable has an elongated shape with several layers of dry golden husk. The taste of the Dutch hybrid spicy, with characteristic notes of bitterness.

Suitable region and climate

Initially, Sturon onions were bred for cultivation in countries with moderate temperatures. This type of climate is present on 25% of the globe. To a large extent, farms for growing this variety are located in Russia, Ukraine and Belarus.

Planting is carried out by seed or sevka regardless of climatic conditions. Sturon applies to winter hybrid. Frost resistance of the root allows you to grow it in colder areas. Planting onions for the winter in Moscow and central Russia begins with the preparatory work on the site.

Landing dates

You can grow a good harvest by choosing the optimal time for agricultural work. Experienced gardeners claim that the onions planted before winter tolerate low temperatures well and sprout quickly in spring.

This variant of embedding is carried out 2 weeks before the onset of the first frost (end of September - beginning of October). For planting this variety in the winter you need to pre-sort sevok and soak for 2 hours in warm water. Bulbs can be planted in the spring (April - May) and earlier, when the earth thaws by 5-6 cm.

Preparation of planting material

To improve germination, breeders recommend that the chernushka be pre-soaked in water for 2-3 hours and left in wet gauze for 2 days.Planting seeds for seed making is painstaking work, so novice gardeners are recommended to buy already prepared onions.

Before using planting material in the form of a set, the following measures should be taken:

  • carefully search the bulbs and discard the spoiled specimens,
  • inspect each head and cut off a dry neck,
  • to accelerate germination, it is recommended to soak the Sturon bulbs for 2-3 hours, as well as the seeds (chernushku). After that, planting material should be washed under running water and dip it for 5 minutes in a weak solution of copper sulphate, prepared in the proportions of one teaspoon per 10 liters of water.

After this treatment, which protects the crop from diseases and pests, the sevok is washed once more and buried in open ground.

Preparation of beds

Agrotechnical work on the site begins with the digging of the soil. Onions Sturon grown on sandy and loamy land. Poorer and harder crops are harvested on sour and heavy ground.

Compost, wood ash, and phosphate fertilizers should be applied to the soil for growing bulbous. It must be remembered that mineral supplements are used in spring, and organic supplements in late autumn.

Landing technology

In April - May, they start planting chernushka to get sevka. The seeds purchased in the store have already been processed with fungicides and biostimulants, but if the owner plans to use the material of his own collection, pretreatment with a weak solution of potassium permanganate will be required.

Before planting nippers on the plot, it is necessary to water the beds copiously and form shallow grooves. It is very important to observe the distance between the rows of 10 cm.

For planting onion varieties Sturon in the fall choose the smallest specimens. Sevok should be immersed in the wells up to 4 cm in depth, while a 2 cm layer of earth should remain above the dry neck. Growing bulbs for greens of this class is carried out at any time of the year in greenhouses in compliance with the temperature regime.

Growing seed from seed

Before you start planting chernushka, you need to evaluate the garden plot. With a lack of precipitation and low occurrence, aquifers of sevka are grown on leveled areas, and with an excess of moisture - on specially formed beds.

Onion Sturon well sprouts after predecessors such as cabbage, cucumbers, beans, radishes. This variety is frost resistant, so the seeds can be planted in the early stages, when the soil thaws 5-7 cm.

Preliminary material needs to be processed: soak for 2-3 hours in a weak solution of potassium permanganate, and then rinse under running water. Purchased planting material does not need such treatment.

Chernushka sown to a depth of 2 cm, leaving 20-30 cm between the rows. With the appearance of the first two leaves, thinning is carried out and repeated as new sprouts germinate until 8–10 cm remains between the bulbs. With the annual cultivation receive small fruits, and large sevok collected only in the second year.

Subtleties of care

Bow Sturon refers to unpretentious plants. But when growing a root crop on a feather and for forming large heads, you need to follow a few simple rules.

After planting seeds or seeding it is necessary to maintain moisture in the soil while loosening it. Watering is carried out as needed, focusing on the dryness of the upper layer of the earth. One month before harvesting, irrigation should be stopped. This happens when the green fades and dries.

Sturon grows well on nutrient loamy soils. The first fertilization is carried out before planting. To do this, the soil must be dug along with chicken droppings or humus.

During the active growing season of the bulbs, it is necessary to feed three times in the form of mineral or organic additives. Regular loosening promotes oxygen saturation and mixing fertilizer with the soil.If you need to get bulbs of large size, it is forbidden to cut off feathers.

According to assurances of breeders, the fruits of this class reach 150-180 g without the use of fertilizers.

Diseases and pests

Onions are protected from spoilage if dill and carrots grow in the nearest beds. Despite the high immunity of this variety, vegetables can be subject to the following diseases:

  • Downy mildew is the most popular pest of onions, which appears in dense soil and with insufficient watering. At defeat leaves become covered with a raid and the plant fades. Pretreatment with a solution of potassium permanganate or planting material or Phyto-plus, Fitosporin,
  • onion mosaic - manifested in the form of yellow spots on the leaves, which quickly dry out. Because of this, the disease heads remain small and poorly stored after harvest. The virus is transmitted by an onion fly,
  • neck rot - striking tree, which lies in storage. The fight consists in the timely removal of damaged copies.

Sturon is exposed to nematodes. For the destruction of pests, it is recommended to spray the beds with a solution based on the “Phosphamide” and “Mercaptophos” preparations.

Harvesting and storage

When the green onion feathers become soft and dry, you must stop all work on the beds. The maturity of the fruit is determined by the moment when the leaves fall to the ground. Harvesting should be carried out in dry weather.

Fruits are forbidden immediately from the garden to place in the basement. Pre-bulbs need to sort, cut off the rhizome and dry neck, to separate the damaged specimens. Harvest is recommended to be stored in plastic or wooden boxes with holes for ventilation. The optimal temperature is + 13-15 ° C. To prevent rotting of root vegetables from time to time they need to sort out and remove damaged bulbs.

Breeding

Independent cultivation of onion sets from seeds is a fairly simple exercise, during which it is very important to take into account the basic rules. First of all it is necessary to observe the landing terms.. In the southern regions, seeds are placed in the ground in spring (late March), and in the central and northern latitudes in the first weeks of April.

Onion Seeds

Soil preparation should begin in the autumn, the following fertilizers are applied to 1 square meter of land for digging:

  • half a bucket compost,
  • 1 cup wood ash,
  • 1 tablespoon phosphate fertilizers,
  • 1 tablespoon superphosphate.

2-3 days before planting, the soil is plowed and form the beds, and then compacted and covered with black film.

Seeds also need to be prepared, for this they are soaked for 4-6 hours in manganese or aloe juice. After that, they are wrapped in a damp cloth and stored in a dark place for 2 days. It is very important to prevent the fabric from drying out.

Soaking seeds onion Sturon before planting

Sowing seeds in the ridge produced by the following algorithm:

  1. To start ridges watered with warm water and form furrows, at a distance of 20 centimeters from each other,
Furrows for sowing onion seeds
  1. The seeds are laid out on the surface. so that the distance between them is equal to 10 centimeters,
Sowing onion seeds on ribbon
  1. Then seeds sprinkled with a thin layer of soil and carefully watered. It is advisable to mulch the planting with peat or compost.

Plant Care

Caring for onion varieties Sturon is divided into two components, because the cultivation of seed and full-grown fruits are significantly different from each other. In the first year of plant life, when the main goal of the gardener is to obtain a quality seed, the onions are cared for as follows:

  1. As soon as the first shoots appear, landing must be thinned. This procedure will help to form a large sevok,
Sprouted onions
  1. Land need regularly loosen,
  2. Watering is carried out once in 7-10 daysorganic or mineral fertilizers are added to the water,
  3. When sprouts reach a height equal to 2 centimeters all work should be stopped.

Then the gardener should wait for the moment of complete wilting of greenery and softening of the neck. In this case, the onions can be dug, dried and prepared for storage.

When growing fruits for eating, perform the following steps:

  1. Bow Sturon must be abundantly watered, preventing the drying of the soil. In one procedure, 12-15 liters of water are consumed per square meter of soil,
  2. After the appearance of the first young landing feathers fertilize with nitrogen fertilizersfor example, urea,
To compensate for the lack of nitrogen in the soil on which the onions grow, it can be watered with urea or with a solution of slurry
  1. Also needed regularly loosen the ground and clean it of weeds.

Characteristics and description of the variety

Sturon is a variety of onions bred by Dutch breeders from the famous German variety Stuttgarter Riesen. Included in the State Register in 2009, allowed to be cultivated in 2 Russian regions: Central and West Siberian. It is recommended to grow it in a 2-year-old culture. Variety refers to medium late, the collection of bulbs can be carried out at 115-130 days from the moment when mass shoots appear.

Bulbs of a grade of Sturon of a cross-elliptic form, 1 or 2 germinal. They are covered with 4-5 dry yellow-colored scales with a brown tint. Juicy scales in this white onion with a slight greenish tinge, with a spicy taste and a rather sharp onion flavor. The neck is of medium size.

The yield of onion varieties Sturon - 2.3-3.4 kg / m 2 with a mass of 1 head 80-100 g. Growth of the bulbs before harvesting reaches 70% and up to 100% - after maturation.

Among the valuable characteristics of the variety are:

  • cold resistance
  • resistance to onion diseases and pests,
  • undemanding care
  • resistance to bolting,
  • good productivity.

The collected bulbs of the Sturon variety are distinguished by good keeping quality: they can be stored for 7–8 months without storage (at a temperature of 2-3 ° C and humidity of 70-80%). This makes it possible to grow this onion for winter sales. The purpose of the variety bulbs is universal, they can be used to add to salads, first and second courses, homemade preparations.

Agrotechnics of cultivation and care

Onions varieties Sturon grown in a two-year culture. In the first year they receive small bulbs (seed buds from seeds), and in the second - large commodity heads. You can also buy ready-made planting material in specialized stores and get turnip harvest in one season. No matter what kind of cultivation is chosen by the gardener, it is necessary to begin with the preparation of the beds.

For the cultivation of onions friable, fertile soil, ideal light loam, rich in nutrients and well lit by the sun, are suitable. The best predecessors of the vegetable are cucumbers, tomatoes, early cabbage, greens and radishes. Under the soil digging from autumn, up to 5 kg of compost or humus and a glass of wood ash per m 2 are introduced. When using mineral fertilizers use complex compounds or phosphorus-potassium, depending on the initial state of the soil.

The plot is deeply dug up and left so until spring. In places with close groundwater storage, as well as the northern regions, onions are grown on raised ridges for faster heating of the soil and its better aeration. If fertilizers have not been applied in the fall, in the spring before planting, the soil is enriched with all three main nutrients - nitrogen, phosphorus and potassium. Use mineral complex compositions.

Sowing seeds start in the earliest terms, in late March - April, depending on the region. The minimum temperature of the soil should be at least 5-8 ° C. Onion seeds Sturon are planted in furrows to a depth of 1-1.5 cm, 10-20 cm are left between rows. Before the emergence of the beds, the beds are covered with a film or other protective material.

To plant seeds in the ground can be dry or previously prepared. The easiest way is to pickle them with potassium permanganate and then keep them in growth stimulant solutions. Also, gardeners practice and sowing germinated seeds. They are placed in a damp cloth and left for 3-4 days in a warm room. This allows you to get shoots much earlier.

Further cultivation of seedlings consists in watering, loosening the soil, feeding, and, if necessary, thinning the plants, if the seeds have been planted densely. Clean it, like a regular onion, after lodging and yellowing tops.

Sevok Sturon planted in the winter or spring. In the first case, the smallest onions up to 1 cm are taken away. The works are started 1-2 weeks before the onset of sustained frost in late September and October. Prepare the beds in advance, cut the grooves at a distance of 20 cm from each other.

Material for planting does not stimulate growth. Sevok with this should be without visible traces of disease, roots and feathers. To prevent diseases, it is only disinfected in fungicidal solutions or potassium permanganate. In the ground planted dry.

For sub-winter planting, the bulbs are buried so that 2-3 cm of soil remain above the neck. Furrows are sprinkled with peat and fertile soil, the beds must be mulched on top. Between the bulbs leave 5-7 cm.

Spring sevok planted in April - early May, guided by weather conditions in the region. In the northern areas of the work carried out later. In contrast to the autumn planting, preference is given to larger onion, up to 2 cm. Only healthy, undamaged and pest-free specimens are selected. Planting material is etched in disinfectant formulations. Many gardeners get a good result, preheating pre-onions, which were stored in the cold, before planting for 3-4 days at the radiators. Or keep it for 10-15 days at room temperature. Planted sevka on the bed according to the scheme: 20 cm between the rows and 7-10 cm between the onions in a row. Depth 2 cm above the neck.

Onion varieties Sturon unpretentious enough, but still requires some care. To give the fall a large turnip in the fall, they need watering, but especially the plants need moisture at the initial stage, as well as during the period of bulb formation. It is also necessary to regularly loosen the ground so that air can penetrate to the roots. The first time planting is treated as soon as shoots appear, then - after each irrigation. 2-3 weeks before harvesting, watering the beds with onions is stopped.

Fertilizers are carried out with organic and mineral fertilizers. At the moment of intensive growth of green mass, nitrogen is used (solution of chicken manure or manure, saltpeter), then complex preparations with microelements, the last dressing is performed by phosphorus-potassium fertilizers. In the second half of the growing season, nitrogen is not used to accelerate ripening and increase the keeping quality of the product.

Onion harvest in Sturon falls on August. Selectively, individual copies can be pulled out even earlier. Bright, thin, glossy surface shirts on a turnip, as well as lodging or yellowing of the lower leaves of the tops serve as a signal for cleaning. Retaining onions in the soil is not worth it, it reduces the storage time in the winter and contributes to the development of disease. After harvesting, the crop is sorted, dried, dispensed and sent to storage. Keep at a temperature of 1-4 ° C and humidity of 80% or 18-22 ° C and humidity of 60-70%. Often at home, these 2 ways to combine. In the same conditions and stored stored sevok.

general information

Onion characteristics Sturon in many ways much better than other popular varieties. In harvesting it belongs to the mid-early varieties. Vegetable ripening takes place approximately two and a half months after germination.This variety is not afraid of frost, so it is great for growing in the regions of the country, even with a harsh climate. In addition to frost, this variety is highly resistant to various diseases and harmful insects. This is a great advantage, since there is no need to use pesticides when growing onions, as a result of which you get environmentally friendly products.

As far as yield is concerned, up to 40 tons of onions can be harvested from one hectare of land. Bulb size is quite large. The average weight of a vegetable is about 165 grams, and the weight of the largest bulbs can exceed 200 grams. Fruits are oval and pale golden color. The flesh is white with a slight green tint, has good density and juiciness. Another advantage of this variety is excellent preservation. With proper storage, onions can retain their taste for eight months.

Selection Tips

Much attention in the cultivation of Sturon onions should be given to the choice of planting material, since this is one of the keys to harvesting a good harvest. This variety can be grown from a single planting material for several years in a row. It should be borne in mind that in the second year the fruits will be large.

In order for the Sturon onion (a description of the variety, reviews and more can be found in the article), gave a big crop, it is best to grow it on loose types of soil with high fertility. On acidic soils yield and quality of onions will be much worse.

If you have not previously grown this variety of onions, then you can buy seeds in any specialty store. When choosing a sev, it is best to use small, strong bulbs, the size of which is about two centimeters. Sevok, which began to rot or was hit by any disease, should not be planted, because it simply will not germinate. If the bulbs sprouted, they are also not suitable for planting.

Planting Storage Recommendations

If the seed was purchased in the fall, then in order to preserve its properties, it is necessary to store it under certain conditions. Experienced farmers perform a special procedure to prevent the onset of rotting or disease of onions. They heat the bow under a certain temperature in four stages. During the first week, the planting material is heated at a temperature of 25 degrees, during the second - 30 and during the third - 35 degrees. The last stage lasts about 10 hours, and the temperature should be 40 degrees. After warming the seed is sent to storage. To do this, use a dry room with good ventilation. It is necessary to store sevok when the air temperature in the room is from 18 to 20 degrees and the humidity level is not more than 70 percent.

The choice of the place and time of landing

Before we talk about when to plant Sturon onions, let's talk about the most suitable place and time for this. Choose a dry and well-lit plot of land on which you will plant onions. It will be just fine if previously it was grown cucumbers, cabbage or radishes. When the snow melts and the ground warms up by about 5 centimeters, you can begin to sow. In most regions of our country, the ideal time for sowing falls in mid-April. But if the weather conditions are favorable, then you can plant at the beginning of the month. This variety is able to withstand frosts up to 4 degrees, so if there will be frosts, nothing will happen to the vegetable.

So, we told about when to plant onions, so now you can talk about the features of sowing and caring for Sturon onions.

Land preparation

In autumn, the land that will be used for growing Sturon onions (fertilizers used for planting different), should be dug up.As a top dressing, a special mixture is used, for the preparation of which a half-bucket of compost is required, a glass of wood ash and a tablespoon of superphosphate and nitroammophos. After the snow melts in the spring, the ground should be plowed up. After the formation of beds the land is covered with black film.

Growing sevka do it yourself

Many novice vegetable growers are interested in the answer to the question of how to plant onion Sturon, so that it gives a rich harvest and has high taste qualities. Shortly before planting the onion beds are watered. Sow planting material can be both rows and tape. In the first case, between the rows should be left approximately 10 centimeters, and in the second - 20 each. You can sow chaotically, without following any regularity. On one square meter of land need about 10 grams of planting material. After sowing, seeds are covered with earth, covered with compost and watered.

How to care for sevka?

The bow of Sturon, the planting of which was discussed above, needs the special care needed to obtain a good harvest. After the onions germinate, it is necessary to thin it. This will produce larger fruits. Further care is based on the periodic loosening of the soil, dressing and regular watering with a small amount of water. When the bow grows to two centimeters, these procedures are terminated. Harvest will be possible after the onion feathers wilt. Next, the fruits are dried and sent to storage until the next season. Small onions, no larger than one centimeter in size, can be sown for the winter. During the spring he will have time to feed on moisture and gain strength, which will allow to get a good harvest.
