Rumba bow

Many European varieties of onions take root well and show high productivity in Russia. Along with popular Dutch developments, British-bred products such as the Rumba onion give excellent results.

The onion variety Rumba was developed by the British firm Allium Seeds UK LTD. This company has a narrowly focused field of activity: it is engaged in the cultivation of onions (yellow, red) and shallots for industrial production and private farms.

In Great Britain, Rumba has become one of the leading varieties of this crop. It is very popular in most regions of Europe, especially in Poland, Belgium, France.

Since 2014, Rumba has been included by the State Sort Commission of the Russian Federation in the register of breeding achievements and zoned for the Central Black Earth Region.

Rumba is a very high-quality variety of onions with medium ripening periods, high-yielding, unpretentious in care, resistant to some diseases, versatile in use. The bulbs are yellow-brown, round, firm and rather large. It is grown by seeds, seedlings and sets.

Rumba cultivar forms bulbs of a leveled spherical shape with a neck of medium thickness and dry outer scales (no more than 5 layers) of a golden-red color. Dimensions are average and above average: weight can reach from 100 to 350 g, but most often this figure is 100-120 g.

The variety belongs to small breeds: 1-2 heads are formed on one bottom. The onion produces light green feathers with a waxy bluish bloom. The density of the bulb is high, without voids in the middle, the inner scales are white and juicy.

Rumba has a spicy taste, with a harmonious combination of sweetness and spicy light bitterness. This onion is used fresh in salads, appetizers, hamburgers. It is used for side dishes: stewed and fried. Various marinade options allow you to prepare many canned preparations for the winter, for example, onions in wine or onion jam.

Rumba is a mid-season variety, but in some regions it ripens late. Most often, after 2-2.5 months (60-80 days) after planting the seed, it is already possible to harvest. Large specimens fully mature in about 3-4 months (100-130 days).

This high-yielding variety yields on an industrial scale from 150 to 500 quintals per hectare. Average indicators range from 190 to 316 c / ha. During harvesting, the indicator of ripe onions is 94%, so part of the harvest is sent to ripening.

The variety shows good keeping quality: in properly organized conditions, the crop can be stored for up to 9 months.

Rumba onions are grown practically throughout the entire territory of the Russian Federation; the variety has sufficient cold resistance even for the northern regions. The best productivity is typical for the southern and temperate latitudes. Variety tests were carried out in the Central Black Earth Region, and the yield of Rumba exceeded the standard for this area.

Seed material (nigella seeds) is planted in the spring, in heated soil, depending on the region: from the beginning of April to the first days of May.During the summer season, full-fledged bulbs will not be able to fully grow and ripen, so seedlings are grown with seeds. In the middle of summer, the sets need to be collected, dried, sorted and stored.

Sevok can be planted in the spring (from April to June) and before winter 2-3 weeks before the onset of frost (in the second decade of September - in the north, in October - in the center of Russia, in early November - in the south). Small onions can be treated with a manganese solution. When planting, the following distances are maintained: 20-40 cm between rows and 5-10 cm between onions. The sevok is buried no more than 5 cm. When planting in spring, the crop is harvested from August to September, focusing on the lodging and yellowing of the onion tops.

For one-year onion cultivation, the seedling method is used: from the last days of February, seeds are sown in containers and boxes, germinated under a film until germination, and after 2 months the seedlings are transferred to the garden bed.

The Rumba onion plantation does not require excessive maintenance. This variety is not prone to shooting. Agricultural technology consists in eliminating weeds, loosening and hilling the soil, regular watering and applying additional fertilizing.

For forcing the feathers, organic and nitrogen-containing fertilizers are required. Ash and a phosphorus-potassium supplement have a positive effect on the formation of bulbs.

During planting of seedlings or seedlings and during the growing season, plants are demanding on the level of moisture: watering should be abundant, about 10-13 liters per 1 m². Before ripening and collecting onions, watering is stopped.

The variety is not very picky about the quality of the soil, although the depleted soil will affect the size of the bulbs. It is important that the soil has a high degree of aeration: the site must be dug up and loosened. Rumba grows in most types of soil, although loam or sandy loam with a neutral acidity level is best. It is undesirable to place the bed on an area with a high level of groundwater.

Rumba is good at resisting infections such as:

• white rot;
• yellow streak (dwarfism);
• bottom rot or fusarium;
• brown leaf spot.

Danger can be posed by onion mosaic virus, downy mildew fungus, neck rot and mold rot that affects onions during storage.

Insecticides are used against onion mites, weevils, aphids, moths and other pests. A good result is given by planting next to plants that repel harmful insects, for example, carrots.
