In recent years, Dutch onion varieties have become increasingly popular among gardeners and farmers. This is due to the fact that they are able to adapt to any climatic conditions, have high immunity and give good yields. One of these is the mid-season Turbo variety.
Breeding history
Turbo onions are a Dutch-bred onion bred by scientists from the agricultural firm Seed Supply B. V. in 2011. After a chain of variety trials, in 2015, the vegetable crop was entered into the State Register of approved for use in the territory of the Russian Federation. The authorship belongs to the breeder Blikman L. The vegetable is cultivated in 8 regions of Russia (Central, Ural, Lower Volga, Central Black Earth, East / West Siberian, Far East, Volgo-Vyatka). Onions are cultivated both in small garden beds and in farm fields,
Description of the variety
The Turbo onion is a compact biennial plant with erect, beautiful feathers. The greenery that forms the basis of the plant is distinguished by a uniform bright emerald color, abundant thickening, dense arrows. Feathers grow in height up to 30-35 cm. On the surface of the feathers a waxy bloom is noticeable, giving the greenery an unusual color. This plaque performs a certain protective function, protecting tissue from damage and frost.
Characteristics of the appearance of plants and bulbs
The Dutch onion stands out among its relatives for its excellent presentation. Specimens ripen aligned and neat. The variety belongs to large-fruited. The average bulb weight is 125-140 grams, sometimes individual specimens grow up to 200 grams. The shape of the bulbs is correct - rounded, with a small neck. The peel of vegetables is smooth, dense, consisting of 2-3 scales of a brown-golden color. Onion pulp is snow-white, with increased density. In structure, the vegetable is small, consisting of one bulb.
The dug vegetables are well transported. And also have a long keeping quality. In a cool (+ 4 ... 6 degrees) and dry basement / cellar, onions can be stored for about 6-8 months. Due to the firmness of the peel and its tight fit, onions can be harvested mechanically.
Purpose and taste
The Dutch vegetable tastes great. The white flesh has a juicy, fleshy, slightly crunchy and tender texture. The taste is dominated by piquant pungency, combined with subtle sweetness. One of the advantages of the variety is the rich vitamin composition of the pulp, in which the increased content of vitamins C, E, PP, B, glycosides, phytoncides, flavonoids, pectins and macro / microelements (potassium, iron, sulfur, phosphorus).
The harvested crop can be widely used in cooking - added to soups, various cold and hot dishes, pickled, used for canning vegetables, and also eaten fresh. Some culinary experts believe that Turbo onions are the perfect variety for pickles.
Maturation
The Dutch variety represents a class of mid-season vegetable crops. From germination to full lodging of feathers, 80-95 days pass. The ripening of the bulbs is not very fast, so you should not hesitate with planting the vegetable. If the standard planting dates are observed, the harvest falls in the second mid-September - early October. The main indicator that onions are worth digging is dried greens.
Yield
The Dutch variety is highly productive.From 1 m2 of plantings, you can dig 5-8.5 kg of juicy, semi-sharp onions. On an industrial scale, the average reaches 245-337 centners / ha of plantings. The maximum record harvest was recorded at the level of 661 c / ha (Moscow region).
Planting dates with seeds, seedlings and seedlings
Planting dates directly depend on the climate of the growing region. On average, sowing seeds into the ground is performed in early May, when the soil is warmed up to + 10 ... 12 degrees. Onion sets are also planted in the first week of May. Before winter, onions are planted in mid-October (at a temperature not exceeding +5 for a week).
Growing and care
In the first year, onions are grown from seeds to obtain sets. In the second year, a tasty and aromatic onion (turnip) is grown from a set planted in open ground. When growing by seed, it is recommended to observe some features of planting: disinfection of seed, treatment with a growth stimulator, deepening of seeds by 1-1.5 cm, observing a distance between them of 1.5-2 cm.
When cultivating seedlings, there are also subtleties: preliminary processing of the bulbs with potassium permanganate and fungicides, deepening by 2 cm, the distance between the bulbs is 5-10 cm, and the distance between the grooves is about 25-50 cm. After sowing, the beds must be watered with warm water. Good precursors for onions are beans, cabbage, courgettes, and cucumbers. It is not recommended to plant onions in one place for more than 4 years in a row.
When planting before winter, the same planting pattern is maintained, and the seedlings are processed and pre-heated. It is very important to comply with the temperature regime - + 3 ... 5 degrees (in warmer weather, it can become rotten and premature shooting)
Onion care consists of standard measures: watering as needed (the soil must have time to dry), loosening the soil after each watering, weeding row spacings, which helps in the fight against weeds, feeding with organic matter and complex fertilizers (2 times per season), disease prevention and pest infestations.
In addition, experienced vegetable growers recommend mulching using cut grass or straw, which slows down the growth and appearance of weeds. It is important to remember that watering is stopped 3 weeks before the onion is harvested. Liquid fertilizers for onions, which are applied to the soil, are considered the best.
Since the onion is an unpretentious and cold-resistant plant, it can be planted both in spring and autumn. It is necessary to properly prepare the planting material, competently prepare the garden bed and determine the timing of planting.
Soil requirements
The vegetable has no special requirements for the structure of the soil. The soil should be light, loose, well-drained, nutritious and fertile. It is important that the soil has neutral or low acidity. The optimal soil is considered to be endowed with high air permeability, as well as diluted with a small amount of sand. Many summer residents plant Dutch onions on sandy loam substrates.
The bow is not as unpretentious as it seems. Good growth requires fertile soil, quality care and nutritious fertilizers. Without top dressing, the bulbs will grow small, and the greens will not be lush. At different stages, it should be fed with different substances. The vegetable needs organic and mineral feeding. A good result for fertilizing onions is the use of folk remedies.
Required climatic conditions
The Dutch variety Turbo is a frost-resistant crop, easily tolerates temperature jumps, short shade and heat, but is very susceptible to dampness. Onions are comfortable to grow in flat, weed-free areas, well-lit by the sun and light throughout the day. In addition, the culture requires protection from drafts, as well as from excessive dampness and stagnant water. It is not recommended to plant Dutch onions on wetlands in the lowlands.
Disease and pest resistance
Despite their high immunity, onions are often exposed to a number of diseases - fusarium, bacteriosis, downy mildew, gray rot. Among the insects that most often attack onion plantings, the tick and the onion fly stand out. Spraying with decoctions of bitter herbs is very effective in pest control.
Despite the fact that the onion is a very useful plant, capable of repelling and killing many microbes and bacteria, it itself is often damaged and suffers from various misfortunes. Diseases and pests of onions can significantly reduce the yield. It is necessary to correctly determine the presence of this or that disease and take appropriate measures in time.
