But the large sevok Senshui goes to get greenery. As soon as warm days come, it actively germinates and gives an early harvest of feathers.
Characteristics of the Senshui onion variety
Winter onion Senshui has good quality characteristics. Vegetable growers from different regions note its stable high yield, unpretentiousness and disease resistance.
Productivity
Senshui is an early maturing variety. This explains its popularity among vegetable growers. The climatic conditions of the regions and the duration of the winter period lead to an urgent need for an early harvest of crops. Podzimnye varieties of onions are able to provide a quick high-quality harvest. It is harvested 2 months earlier than during the spring planting of spring varieties.
The yield of the variety is 4 kg of heads per 1 sq. m of landing area. The weight of one bulb reaches 150-180 g, with good agricultural technology, heads are harvested, 250 g each. The pulp is juicy, white. You can increase the yield by competent regulation of the watering of the variety.
Disease and pest resistance
The originators in the description of the yellow onion Senshui indicate the high resistance of the plant to powdery mildew.
Advantages and disadvantages of the variety
Based on reviews of winter onions Senshui, you can make a list of the pros and cons of the culture.
Advantages:
- Early maturity. The feather is ready for use in cooking in early spring, when planted in the second year, the bulbs are ready for harvest in mid-summer.
- Frost resistance. The Senshui variety tolerates a drop in temperature to -15 ° C. In addition, even lower temperatures do no harm if severe frosts are short-lived.
- Yield, which is considered high enough for winter varieties.
- Taste qualities allow you to use the vegetable not only in the preparation of fresh dishes, but also to preserve the bulbs.
- Storage and transportability at a high level. Senshui lies up to 6 months without losing its qualities.
- Not subject to shooting.
- Unpretentiousness. Care consists of a short list of activities. And in the spring, the bulbs do not even need watering.
The disadvantage is the lower yield compared to spring varieties. Although careful selection of planting material greatly increases this figure. The second disadvantage is a short shelf life. But all early-ripening bulbous varieties have this drawback.
Planting and care for onions
Planting winter onions has its own characteristics. For winter varieties, all recommendations must be carefully followed. Only in this case, you can count on a decent result. The following will present the basic requirements for planting and caring for Senshui onions.
Planting dates for onions
Winter sevok Senshui is planted at a time that depends on the climatic characteristics of the region. If these are the southern regions, then the optimal time is November. For the northern ones, the dates should be shifted by a month and a half and landing should be carried out in September or October.
Frozen soil will harm the planting material, and early planting can lead to premature germination.
Preparation of beds
The place for the beds should be chosen carefully. Senshui prefers a sheltered and well-lit area. The lowland is not suitable due to the accumulation of water when the snow melts. In such conditions, the bulbs begin to warm up quickly.
The bed is prepared in compliance with crop rotation. Senshui can be planted no earlier than 5 years after the previous cultivation of legumes, bulbs and potatoes. Ideal predecessors are beets, carrots, cabbage, greens.
Preparation begins 2 weeks before the scheduled landing date. The soil is dug up with the simultaneous introduction of humus and mineral fertilizers, then the bed is left for the soil to settle.
Before planting, the bed is sprinkled with wood ash and a comb 20 cm high is formed.
Landing onions
Preliminary preparation of planting material is not required. The sevok does not need to be soaked or trimmed.
In the prepared bed, you will need to make furrows. The depth of each is not more than 5 cm, and the distance between them is about 15 cm.
Sets of onion Senshui are placed along the furrow. It is important at the time of planting to ensure that the neck is 2 cm below ground level. The distance between two bulbs is kept no more than 15 cm.
From above, the seedlings are covered with earth, then with humus. Be sure to insulate the bed by laying a layer of spruce branches or sawdust. You don’t need to water right away. You can slightly moisten the bed after 10 days in dry weather.
Growing onions
Senshui onion care begins with the onset of the spring period. With stable heat, the bed is freed from covering mulch, then fertilized with urea. For 1 sq. m will need 10 g of the substance.
Then the soil is loosened and sprinkled with a thin layer of wood ash. After the formation of 4 sheets, the culture is fed with phosphorus (20 g per 1 sq. M) and potassium (10 g per 1 sq. M). The best way to fertilize Senshui onions is watering with liquid solutions.
The beds are watered not earlier than May and as needed. Each watering is completed with careful loosening.
Harvesting and storage of crops
The ripening of the variety begins in early summer. Depending on the growing region, the harvest time comes in June or July. For 2 weeks stop watering and loosening. During this period, the heads gain maximum weight, and their scales dry out. Therefore, you should not stimulate the growth of greenery by such actions.
Harvesting begins before the onset of complete yellowing of the leaves. Otherwise, after the first rain, Senshui will begin to form new roots.
The bulbs are carefully pulled out of the ground, laid out on the ground to dry. In dry weather, drying lasts a week. In addition to drying, the sun’s rays perform a disinfecting effect. A week later, the crop is sent under a canopy and kept there for 20 days. Such heads are better stored. During the rainy season, the crop is transferred to a well-ventilated, but closed room for drying.
Then carry out a bulkhead. Undamaged dense bulbs are laid aside for storage. The leaves are cut at a height of 5 cm from the neck. Then cut off the roots without touching the bottom. Place Senshui in nets, baskets or boxes with ventilated walls. Many weave pigtails, which make it easier to control the condition of the bulbs during storage.
Ways to propagate onions
The Senshui onion variety belongs to hybrid forms, therefore it propagates by planting sets. If you want to grow planting material yourself, then the seeds should be purchased in specialized stores. It is not recommended to collect seeds on your own. Hybrid varieties with this method of reproduction do not retain their characteristics.
Diseases and pests, methods of control and prevention
Before planting, the beds must be treated with products from tobacco thrips, nematodes, and onion flies. During the period of growing winter onions, it is necessary to regularly inspect the plantings. Senshui may be subject to insect infestation prior to harvest. Gardeners are advised to stock up on Aktara or Medvedox. From folk remedies, infusions of marigolds, alkaloid lupine are used. Additionally frame the onion bed with rows of marigolds.
Conclusion
Senshui onion is an excellent variety for private cultivation and farming. Onions are perfectly adapted to the climate of the middle zone, tolerate winter, give an early harvest, and have a good taste. The ability to transport allows you to sell the crop in other areas without loss.
