The great advantage of this hybrid is that it is zoned and successfully grown in the Central, Northwestern, Ural, Siberian, Far Eastern regions, as well as throughout the south of the country. At the same time, regardless of the growing region, summer residents receive a stable harvest without much effort. The only difference is that in the south of the country the harvest is obtained from the first year after sowing the seeds, and in other regions - in the second year after planting the onion sets.

Characteristics

“Golden Semko” belongs to the early ripening varieties; the harvest can be harvested 75-80 days after emergence.
During this time, an excellent round-shaped bulb weighing from 70 to 100 grams manages to form from a tiny seed. The neck is thin, dry scales are golden in color, the bulbs are small-nested, the variety is not suitable for growing green feathers.

Onions have a positive effect on the immune system, improve appetite and promote better absorption of food.

The hybrid is almost not susceptible to common diseases and is characterized by high productivity; 2.5-3 months after sowing, up to 5 kg of onions can be obtained from 1 m2. Also, the variety can be stored for a long time, for 5-7 months, on average, only 5% of the harvest spoils. It can be cultivated throughout the country, but in the south it is grown as an annual crop, and in the northern regions onions ripen from sets in the second year.

Interesting fact! Onions contain more sugar than apples or pears.

Growing methods

Seeds of this variety have a relatively high price. This is due to the fact that “Golden Semko” is very profitable to cultivate using seedlings. Experienced agronomists sow seeds before winter in order to get seedlings when spring arrives. With this method of sowing, the harvest is earlier and more abundant. But in this case, you need to use 10% more seed, since not all grains will survive the winter. Before planting, the seeds are checked for germination; to do this, take 10 pieces and wrap them in a damp cloth, and germinate for three days; if 7 out of 10 have sprouted, it means they are suitable for sowing. We must not forget about pre-treatment with disinfectants.

You can also grow onions from sets; this method is used in cold regions, or for an earlier harvest. In order to get a decent result, it is very important to select high-quality bulbs with a diameter of 1 to 3 cm. They should be:

• Dense;
• without any damage;
• dry;
• no foreign odor;

Before planting, it is dried for a week at a temperature of 35-40 degrees and treated with a solution of copper sulfate

Harvesting

The harvest time for the early ripening hybrid Golden Semko is mid-July. Drying feathers are one of the first signs of the beginning of the harvest. It is better to collect in dry, clear weather.

If the planting was correct, then the shoulders of the bulbs are slightly exposed and there are no problems with pulling them out. In case of difficulties, you can use a shovel, digging carefully so as not to damage the fruits.

Do not throw the fruits away; damage will reduce the shelf life. The yield of the variety with proper agricultural technology reaches 5 kg per m². Ripening over 95% at the time of harvest is one of the advantages of the variety. After harvesting the beds, the bulbs should be left to air for several hours.

Growing from seeds

The soil is pre-moistened, then shallow grooves are made in it at a distance of 5-10 centimeters. When laying out the seeds, leave 1.5 centimeters between them. Then the seeds are sprinkled with soil and watered. At the end, the planting needs to be covered with film, this will create a greenhouse effect and speed up the emergence of seedlings. When sprouts appear on the soil surface, the cover is removed.

In the future, the seedlings must be regularly watered and loosened. For irrigation, it is better to use settled water at room temperature. Before planting in the soil, young plants need to be hardened off.

Productivity

In suitable light, loosened soil enriched with nutrients, Red Semco onions ripen 90-95 days after germination. Around mid-to-late August, the onion feathers begin to dry out, and the bulbs begin to peek out from under the ground. All this speaks of their maturation.

To harvest onions, you should choose a dry and sunny day. Then you can immediately lay out the bulbs and let them dry for 7-10 days. Some may not ripen; for this, the crop is placed in a special warehouse or storage facility, where it will be dark, cool, but not too humid, in order to achieve 100% ripening.

Transferring seedlings to a permanent place

Typically, seedlings are transplanted in April, by which time they should be at least 50 days old. Before planting, the soil is plowed, leveled and watered abundantly. Then shallow holes are made in the ground, the distance between them should be approximately 10 cm. Then the onion seedlings are transplanted to a new place and watered. Subsequently, you need to water the onions once every 14 days. Loosen the soil at least once a month.

Diseases and pests

Despite genetic resistance to many diseases, in unfavorable conditions it can be susceptible to the following diseases:

• Putrefactive infections.
• Powdery mildew.
• Fusarium.
• Rust.

For most diseases, a favorable environment is excessive moisture and an acidic environment. To prevent diseases, you need to control the level of moisture and acidity of the soil. You can reduce acidity by adding chalk.

Pests:

• Caterpillars.
• Onion fly.
• Mol.
• Secretive proboscis.

To combat them, contact and intestinal insecticides are effective:

• "Sumi alpha."
• "Inta-Vir".
• "Arrivo".
• Chlorophos.
• Fozalan.

With the constant use of insecticides of the same type, insects develop addiction. Therefore, alternation is necessary.

Planting sets

The sets are planted in pre-fertilized soil, the holes are made 5 cm deep, 20 cm are left between rows, and 10-15 cm between bulbs. When the planting procedure is completed, I fill the furrows with substrate and compact them a little. It is advisable to do this in cloudy weather. Sevok can be planted both in spring and autumn.

Growing and care

To obtain maximum yield, it is necessary to create favorable conditions for the crop. Onions love light, warmth and do not tolerate drafts. Therefore, you need to choose a site that is sunny and protected from the wind. An important rule when growing any crops is to observe crop rotation; onions grow well after cucumbers and potatoes. You cannot plant where garlic and onions were located last year.

The variety is unpretentious in terms of soil composition, the main thing is neutral acidity and fertilization with organic matter before planting; in the future, the crop does not need fertilizing. “Golden Semko” tolerates low temperatures well, but the main thing is that it does not drag on for too long, otherwise the bulbs may die. The process of seed germination and sowing begins at a temperature of +4. To form the onion, the temperature must be at least +12 degrees.

Important! When planted in the shade, the bow shrinks and shoots arrows.

It needs to be watered as the soil dries, after which it is advisable to loosen the rows. You should also regularly weed the area to remove weeds. Three weeks before harvest, watering should be stopped.

Caring for a plant in open ground

Much depends on the correct planting of onions, but for proper development the crop requires some care.

Watering

The frequency of watering Golden Semko should be based on the condition of the soil. Overmoistening should be avoided. Moisture deficiency, which is especially dangerous during the period of crop growth, is also not allowed. The optimal frequency of watering is once a week. The water should be warm and settled.

On dry days, watering should be increased more often, and on rainy days, it should be stopped completely. If the soil dries out, increase watering frequency.

If greenhouses are used to grow Golden Semko, you can use a drip irrigation system.

3-4 weeks before harvesting, watering should be completely stopped.

Top dressing

The need for fertilizing is determined by the state of the crop. It is recommended to use organic fertilizers. This can be an infusion of mullein or chicken droppings. You need to use it for watering, adding a glass to a bucket of water. Use one bucket for 3 square meters. m. It is recommended to fertilize 2 weeks after planting the crop.

If the growth of the onion is slow and it looks lifeless, then emergency measures are needed. For this, a urea solution is used. You need to add 30 g of the product to a bucket of water and generously water the plantings.

Weeding and loosening

It is periodically necessary to loosen the row spacing to ensure proper soil aeration. It is more convenient and effective to do this after watering.

Regular weeding of the crop is also important. If you do not get rid of weeds in a timely manner, the growth and development of onions will slow down. Orient the frequency of weeding to the characteristics of your site. If fresh manure was used in the fall, the activity of weeds will be increased.

Pest and disease control

Golden Semko has excellent immunity to disease, but this does not exclude pests. If they are already infested, then it is worth using insecticides such as Actellik, Aktara, Bitoxibacillin, Gomelin. Copper sulfate is effective as a preventative measure: you need to add a teaspoon of the product to a 10-liter bucket of water and treat green feathers with it.

An unfavorable environment can provoke fungal diseases: rust, fusarium, smut, powdery mildew, including downy mildew (downy mildew). For treatment, fungicides such as Previcura, Infinito, Teldora, and Consento are needed.
