The universal variety of onions Myachkovsky 300 has been grown by domestic agronomists for a long time. During this period, he received the approval of summer residents and became in demand in small farms.
Breeding history
The Myachkovsky 300 was approved for use in 1985. The varietal plant is not affected by insects, therefore it does not require additional treatments.
Description of the variety
One of the high indicators that this variety has onion is ripeness. He has it from 75 to 99% before harvesting. This is a small-breasted bow, in which up to two heads are formed in one nest.
Myachkovsky 300 demonstrates excellent keeping quality. It is recommended to grow it from seeds, if an annual crop is expected, and from seed, if a two-year one. In addition, Myachkovsky 300 is famous for its stable yield.
Characteristics of the appearance of plants and bulbs
The bulbous head can be flat or round-flat. The weight usually reaches 41-69 grams. Dry husk is yellow, juicy - white. The onion variety Myachkovsky 300 has an average density.
Purpose and taste
The taste of this onion is semi-sharp, it has a universal purpose, which means it goes to greens and to the head.
Maturation
This variety is early ripe, from the moment the shoots appear in the soil to the collection of the bulbs, it takes from 90 to 100 days. If the Myachkovsky 300 onion is grown on a feather, then the growing period is reduced to 65-75 days.
Yield
Myachkovsky 300 gives a high yield, on average, for industrial cultivation, it is 197-315 c / ha.
Growing regions
Myachkovsky 300 is grown by domestic agronomists in the North-West, Central, Ural and other regions of our country.
Planting dates with seeds, seedlings and seedlings
When the Myachkovsky 300 onions are grown through seedlings, the seeds are sown in March. At the beginning of May, the plants reach the required growth so that they can be transferred to open ground.
Growing and care
The optimal scheme for planting Myachkovsky 300 is 5-7x10-15 cm. The place must be sunny.
The optimum temperature for differentiation of the buds Myachkovsky 300 is from 4 to 8 degrees, therefore, it is necessary to plant seedlings and seedlings in open ground 10-15 days later than sowing seeds so that the soil warms up to 8-9 degrees. Optimal conditions for this occur in the third decade of March - early April, depending on the zone.
In order to prevent the shooting of the Myachkovsky 300 onion when grown from seedlings, its seeds are stored in winter at a temperature of 18-22 degrees. However, at this temperature, the bulbs of this variety significantly lose their weight, and small specimens (the most valuable seed) can dry out. Therefore, in the autumn sevok Myachkovsky 300 is well dried and stored at a temperature of 18-20 degrees and a relative humidity of 55-60%, in winter - at temperatures from -3 to +1, and in spring 20-30 days before disembarkation - at 20- 25 degrees.
This variety of onions is required to ensure optimal watering. In industrial planting, a drip irrigation system is usually used.
Seedlings of Myachkovsky 300 are grown in greenhouses.Before the emergence of seedlings, the temperature is maintained at the level of 18-20, after their emergence within 5-10 days - 12-15, later - 16-18 degrees Celsius. During the seedling period, Myachkovsky 300 does not break through.
10-12 days before disembarkation, the seedlings of Myachkovsky 300 are hardened. All plants should be in the 4-5 leaf phase. The material must be sorted (reject underdeveloped seedlings and damaged by diseases). Before planting, the roots of Myachkovsky 300 are shortened by 2/3 of the length so that they do not bend, and by 1/3 of the leaves to reduce the surface of moisture evaporation. Plants are planted in furrows 0.5-1.0 cm deeper than they grew before.
You can use a wide-row planting method for this variety (45, 60, 70 cm) or ribbon planting (20 + 50 cm). The distance between plants in a row is 6-8 cm. If the soil is not sufficiently moist, watering is carried out before planting Myachkovsky 300 or immediately after planting. The soil in the aisles is loosened.
When growing onions Myachkovsky 300 by seedlings, its ripening is significantly accelerated and the commercial quality is improved.
If it is used for planting sets, then it is sorted 5-6 days before planting, warmed up in a well-ventilated room at a temperature of 30-35 degrees. For disinfection from pathogens of fungal diseases, 8 hours before the end of warming up, the temperature is raised to 40-42 degrees, then with Myachkovsky 300 there will be less trouble.
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 increased exactingness of the Myachkovsky 300 onion to soil fertility is due to the fact that, in comparison with other vegetable crops, it forms a small and weakly branched root system, most of which is located in the arable soil layer. From organic fertilizers under the onion of this variety, humus should be applied at the rate of 20-30 t / ha and mineral fertilizers, depending on the data obtained after soil analysis.
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.
Disease and pest resistance
This variety has excellent immunity to pests, but from the most common diseases in this culture, it will be necessary to carry out preventive treatment with fungicides.
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.
Review overview
According to summer residents, Myachkovsky 300 gives an excellent harvest if it is grown at home from seedlings.It is very tasty, juicy and has an attractive presentation. It is stored for a long time if the proper conditions are provided.
The only thing that is scary is a large amount of moisture, which leads to the development of a disease such as downy mildew. There are fewer problems with Myachkovsky 300, when the summer is warm and there is little rainfall, then you can control watering and monitor the amount of moisture in the soil.
