Preparing the beds

The yield depends on the right place. The beds are made in an open, level, lighted place without drafts. It is ineffective to grow seedlings in a lowland, since with the arrival of warming, the beds will be in the water, which will lead to the death of the crop.

The beds are prepared in advance, one month before disembarkation. After digging, the soil is fed with complex mineral fertilizers and disinfected with a copper-containing solution. For top dressing, it is better to use wood ash, humus or rotted compost. Fertilizing the soil with fresh manure is not recommended, as the plant will build up a green mass and make the bulb loose. Such a vegetable is not subject to long-term storage.

Due to its unpretentiousness, the variety can be planted in any soil.

  2. When using shallow seedlings, the depth should be 2-3 cm, when planting large specimens - 3-4 cm.
  3. To have a high yield, planting is best done in a checkerboard pattern.
  4. The planting material is covered with soil and mulched. No watering is required after planting.

Harvesting and storage

The growing season for the Radar onion is 250 days. The crop is harvested only after the bulb has formed. The degree of maturity is determined by the loss of elasticity and yellowing of the leaf, as well as after the head is overgrown with light golden scales.

The crop is dug up in dry weather and left for 2-3 days in the open sun to dry. To maintain freshness for a long time, it must dry thoroughly. If harvesting is carried out in damp weather, the crop is washed and peeled. Feathers, roots are cut and removed to dry in a well-ventilated area. As soon as the onion neck dries out, it is folded for long-term storage.

Diseases and pests, methods of control and prevention

For treatment, chemical and folk remedies are used:

  1. Drug treatment Aktar, Fly eater or Carat Zeon.
  2. Carrots, marigolds, valerian, mint or tomatoes can be planted next to the plant. The smell of these plants repels insects.
  3. Before planting, process the seedlings in a weak solution of potassium permanganate.
  4. Observance of crop rotation will help to rid the plant of onion flies.


The disease can be determined by the formation of gray plaque on the foliage. Without treatment, the entire feather is affected and the plant dies. The disease spreads quickly to healthy plants, resulting in lower yields, poor bulb quality and shorter shelf life.

Preventive measures against downy mildew:

  • compliance with crop rotation;
  • the use of high-quality planting material;
  • sevka processing;
  • once every 7 days, dusting the soil with wood ash;
  • once a month spraying plants with Bordeaux liquid.
