Features of planting and growing

Onions Radar can be grown from seedlings or seeds by sowing them on seedlings. Most often, gardeners choose the seedless method, since it requires less effort.

Preparing for landing

First of all, high-quality planting material is chosen: seedlings up to 1 cm in diameter, without damage, signs of rot or germination. The larger the bulbs, the higher the risk of shooting next year.

Winter onion sowing Radar is dried in advance: laid out on a warm, but not hot, battery and left for 2-3 weeks. After that, the planting material is disinfected: the bulbs are placed in a saline solution (1 tbsp salt per 1 liter of hot water) for 5 minutes, and then in a strong solution of potassium permanganate for half an hour. Then the set is thoroughly washed in clean water.

About 1-1.5 months before planting the seedlings, the soil is prepared. The soil is cleaned of plant residues, dug up, poured with a solution of potassium permanganate for disinfection and fertilizers are applied: humus, superphosphate, wood ash and potassium salt.

Reference. It is not recommended to fertilize the soil with fresh manure - this will lead to an increase in green mass and make the bulbs loose, which will shorten the period harvest storage.

Ground requirements

This variety has no special soil requirements. Onions grow well in any soil, regardless of its composition and acidity.

Timing, scheme and landing rules

Sevok is planted during October; more precise dates depend on the climatic conditions of the growing region. In the North-West region, it is planted in early October, in the Moscow region - in the middle, in the Volgograd region, planting is permissible even in early November.

Landing scheme:

1. Prepare the beds at a distance of 20-30 cm from each other.
2. Make furrows in the beds about 4 cm deep.
3. Place the bulbs in them, deepening by 2-3 cm (for large specimens - 3-4 cm) and maintaining an interval of 10 cm.
4. Sprinkle the planting material with earth and mulch the beds with dry leaves, straw, humus or spruce branches.

The radar can also be grown from seeds. They are sown in August on a previously prepared and fertilized plot according to the 1x10 scheme, deepening by 3 cm. Then the soil is watered and mulched.

Reference. For higher yields, planting is carried out in a checkerboard pattern.

Growing features

The quality and quantity of the harvest largely depends on how correctly the place for planting the onions was chosen. The site should be well lit and protected from drafts, located on a plain or low rise. Moisture often accumulates in the lowlands, which leads to the death of the crop.

This variety is not recommended for planting where bulbous and legumes, potatoes, carrots and celery used to grow. The best predecessors are garlic, mustard, rapeseed, cereals (except oats).

Reference. Onion Radar tolerates temperatures down to -23 ° C under snow and up to -15 ° C without it.

The nuances of care

Radar is an unpretentious bow. Nevertheless, in order to obtain a high-quality harvest, it requires minimal care in the form of regular watering, loosening the soil and fertilizing.

Watering mode

In mid-May, the onions begin to water. The optimal frequency of watering is 1-2 times a week, depending on the climate of the region and the amount of precipitation.

Reference. Water for irrigation should be settled and heated to room temperature.

Loosening the soil and weeding

The soil is weeded as needed - weeds are removed so that it does not take moisture and nutrients from the soil.

The soil is loosened shallowly so as not to damage the plant root system. For the first time, this is done immediately after removing the winter shelter, and then after each watering or rainfall. This procedure improves the moisture and air permeability of the soil and prevents the formation of a hard crust on the surface.

Reference. To reduce the amount of loosening, the soil is mulched - the procedure retains moisture and limits the growth of weeds.

Top dressing

Plants are fed twice:

• in the spring, after removing the mulch;
• when 4 leaves are formed on the plants.

The most suitable fertilizers for onions:

• mullein mixed with water in a ratio of 1:10;
• bird droppings solution (1:15);
• wood ash in dry form or diluted in water (1 tbsp. l. per 10 l).

Disease and pest control

Mistakes in onion care can lead to a decrease in its immunity.

The development of downy mildew (downy mildew) is caused by improper irrigation and waterlogging of the soil. Affected plants are sprayed 2-3 times (with a break of 10 days) with the preparation "HOM" or a solution of copper sulfate. For prevention purposes, leaves that have reached a height of 10 cm are sprayed with Bordeaux liquid, and the beds are powdered with wood ash.

The most dangerous insects for Radar are onion flies. To pests have not spread over the site, the onion is sprayed 2-3 times with saline (1 glass per 10 liters of water) and regularly dusted with wood ash or tobacco dust. In case of severe damage, the plants are treated with insecticidal preparations, for example, "Aktara" or "Alatar".

Harvesting and storage

The readiness of the crop for harvesting is indicated by yellowing and lodging of the leaves, as well as the overgrowth of the bulbs with golden brown husks.

How and when to collect

Harvested on a dry and sunny day. This is done manually, digging in the bulbs with a shovel or pitchfork and pulling them out of the ground by the leaves, or with the help of an onion harvester.

Storage features and keeping quality of the variety

The collected bulbs are sorted according to size and quality. Smaller heads are suitable for winter landing, and those that are larger and do not have any damage or traces of rot - for storage in winter. After that, the onions are dried outside in the sun for about three days or about 10 days in a well-ventilated area - until the root collar dries up.

Then the roots and feathers of the bulbs are cut off, the heads are folded into boxes or bags and placed in a cool place with good ventilation and moderate humidity. In such conditions, the Radar is stored until mid-winter - early spring.

What can be the difficulties in growing

Problems you can face when growing Radar onions:

• germination of onions in April due to the wrong time for planting the seedlings;
• decay of bulbs in case of planting in lowlands or over-watering;
• no germination when planting onions deeper than 10 cm.

Tips from experienced gardeners

Recommendations from farmers who have been growing this variety for a long time:

1. Plant mint, carrots, marigolds or tomatoes next to onions - their smell repels pests.
