The yield of the variety is 5-8.5 kg per square meter, with industrial cultivation - 250-340 c / ha. The maximum indicator - 661 c / ha is registered in the Moscow region. Marketable yield of 20 kg / ha compared to the standard onion variety Stuttgarter Riesen.

When to plant Turbo onions
The timing of planting Turbo onions depends on the cultivation method (seeds, sets), as well as on the climatic conditions of the region. The frost resistance of this crop is average, and the ripening rate is slow. Therefore, when selecting the timing, it is recommended to focus on the following periods:
- Seeds are planted in open ground in the first half of May, when the soil warms up to a temperature of at least 10 degrees. You can check it by burying the thermometer in the ground for 10-15 minutes.

Planting methods Turbo onions

- from seeds (for turnips and greens);
- from sevka (on a turnip);

Growing Turbo onions from seeds
A week before planting, Turbo onion seeds need to be prepared by following several steps:
- hold for half an hour in a weak solution of potassium permanganate;
- place in warm water for several hours;
- let dry at room temperature;
- soak for several hours in a growth stimulant solution ("Kornevin," Epin ");
- wrap in cheesecloth, put on a saucer with water and hold for a week at room temperature.
The landing site should be open and protected from winds, without stagnant moisture (lowlands are excluded). The soil is fertile, light (loam or sandy loam). If the soil is depleted, it must be fertilized when digging, sealed with a complex mineral (40 g per 1 m2) or organic fertilizer (compost, humus in the amount of 5 kg per 1 m2).
Before planting, several grooves are marked with a depth of 2 cm at a distance of 10 cm. Then the seeds are planted at an interval of 10 cm, sprinkled with soil and watered a little.
Seeds and sets are planted to a depth of 2 cm
Sowing seedlings in spring
Preparing the soil before planting Turbo onion sets is exactly the same. At the same time, the set itself also needs processing. Select healthy seed without damage. The bulbs are heated for 6-8 hours at a temperature of 45 degrees.
Then etched in a weak solution of potassium permanganate or fungicide for half an hour. Spread out in one layer and leave to dry at room temperature. The planting pattern is the same - 2 cm deep, 10 cm spacing, 50 cm furrow spacing.
Planting Turbo onions before winter
Planting before winter begins in October, when in the daytime the temperature does not rise above 5 degrees Celsius. The site is cleaned, the soil is dug up and fertilized. The sevok is prepared as described above and planted in the same way.

- It is enough to apply top dressing twice a season.When the feathers grow to 10 cm, they give organic matter (mullein, humates), and after another three weeks - complex fertilizer (30-40 g per 10 l of water per 1 m2 landings).
- Weed grass will appear in two weeks - from that moment on, they do regular weeding. To keep weeds as small as possible, plantings are mulched with straw, grass cuttings or sawdust.
