Dutch onion varieties are very fond of growing both gardeners and farmers, since vegetables quickly adapt to climatic conditions, practically do not get sick, are unpretentious in care, and also give high yields. The mid-season onion variety Setton is endowed with such characteristics - the most productive when grown in the Central region.
Breeding history
Setton onions is a representative of the Dutch selection, created by scientists of the agricultural company Syngenta Seeds B. V. in 2001. The parent form of this variety is Sturon onion. After a series of variety trials, in 2015, the crop was entered into the register of approved for use on the territory of the Russian Federation. The author of the variety is the breeder Wijnker Thaam. It is recommended to grow a vegetable in open ground - vegetable gardens, fields, farmland.
Description of the variety
The Dutch vegetable is a compact plant with an erect rosette. Onion feathers have a uniform bright emerald color, light waxy bloom, moderate thickening. Greenery grows up to 40-45 cm high. During the growing season, arrows are practically not formed.
Characteristics of the appearance of plants and bulbs
The bulbs ripen well aligned and beautiful, so the variety is massively grown for sale. The variety belongs to large-fruited. The average weight of specimens is 70-90 grams, sometimes vegetables weighing 110-200 grams ripen. The shape of the bulbs is round or elliptical, with an elongated and narrowed neck. The surface of the onion is smooth, shiny and firm, consisting of a four-layer brown-golden hull. Onion pulp is snow-white. The fruit density is high. The structure of the vegetable is small, since it consists of one onion.
Dug out onions can easily carry transportation over long distances, and can also be stored for a long time in a dry, dark, cool place without rotting and sprouting. The shelf life of a vegetable crop is about 6-7 months.
Purpose and taste
Dutch vegetable is famous for its excellent taste. The snow-white pulp is characterized by a fleshy, tender, juicy and slightly crunchy texture. The taste is dominated by slight pungency, subtle sweetness and hints of piquancy. There is no pronounced bitterness and pungency in the vegetable. Onion pulp contains an increased amount of vitamins B, PP, C, K, as well as mineral components, amino acids and fatty acids Omega-3, Omega-6.
Harvested onions are widely used in cooking - they are added to salads, first courses, meat, canning, and pickled. Due to its rich chemical composition, Setton onions are used in folk medicine and cosmetology.
Maturation
The Dutch vegetable is of the mid-season class. From the mass germination of sprouts to ripe bulbs in the beds, 80-90 days pass. Ripening in the culture is slow. Bulbs can be harvested at the end of July and continued throughout August and early September. As soon as a third of the feathers wither and spread to the ground, harvesting can begin.
Yield
The productivity of this variety is high. In a favorable environment and with proper care, up to 6 kg of juicy bulbs can be dug from 1 m2. The average yield is 185-285 c / ha.
Planting dates with seeds, seedlings and seedlings
Sowing seeds is usually carried out from mid-April to the first week of May. Sevok can be planted in open ground at the beginning of May, when the temperature regime has stabilized (+ 15-18) and the soil has warmed up to + 12-13 degrees.Directly the timing of planting onions depends on the climatic characteristics of the growing region. In addition, seedlings are planted before winter - as a rule, this is the end of October - early November (the air temperature should be at +5).
Growing and care
The Dutch onion variety is grown mainly by seeds and sets. With the seed method, some features are taken into account: the seed is pre-disinfected and treated with a growth stimulator, the grooves are prepared with a depth of 1-2 cm, where the seeds are evenly distributed, the distance between the rows is 15 cm.
When planting with sevkom, there are also a number of features. The bulbs must be of the same size, free from damage and no foreign smell. Deepening into the soil is carried out by 2 cm, observing the distance between the heads of 8-10 cm, and 20 cm between the rows.
Sowing seedlings before winter is carried out according to the same scheme as for spring planting, but the deepening into the ground should be stronger - up to 8 cm. Cucumbers, potatoes, tomatoes and cabbage are considered the best predecessors for onions.
The agricultural technology of vegetable culture consists of basic measures: abundant watering, especially during the period of feather growth (they are completely stopped 3 weeks before digging), top dressing three times per season (organic matter, phosphorus-potassium complexes and calcium), loosening and weeding, disease prevention, and insect invasions. Many experienced vegetable growers recommend light mulching with sawdust and humus, which inhibits the appearance of weeds.
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
Vegetable crops do not have special conditions with regard to the structure of the soil. Onions grow comfortably on loose, fertile, well-drained, breathable and moderately moist soils. In addition, there should not be a close occurrence of groundwater, as well as high acidity. Nutritious sandstones will be optimal.
The bow is not as unpretentious as it seems. For good growth, you need 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
Dutch onion is a frost-resistant crop, easily tolerates drought, as well as temperature fluctuations. In the absence of snow cover, the bow survives at -15 degrees, and during snowy periods it can withstand up to -23-34 ° C.
For growing a vegetable, a flat, weed-free area is selected, abundantly illuminated by the sun and light throughout the day. Some farmers prefer to plant onions in low elevations where there is draft protection. In addition, the culture is very susceptible to moisture stagnation, waterlogging, so the soil structure and moisture level should be controlled.
Disease and pest resistance
This vegetable crop has strong immunity that protects against many fungal diseases.Violation of agricultural technology or dampness / humidity can provoke diseases. Among the diseases that a vegetable may be exposed to, it is worth noting downy mildew, neck rot and fusarium wilting. For the prevention of fungal infections, fungicides or a solution of copper sulfate are used.
Pests attacking plants include onion flies and nematodes. In the fight against pests, spraying with a solution with the addition of wood ash is effective. Saline is very effective against nematodes.
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.
