Description

Bamberger attracts attention with its taste characteristics, which are similar to salad varieties.

Appearance

Let's look at the characteristics of the variety in more detail:

• shape – round, elongated;
• fruit sizes are average;
• fruit weight – up to 100 g;
• the length of one head is up to 10 cm;
• pulp color – white;
• husk color – yellow-brown;
• taste – sweet, no pronounced bitterness;
• yield – 6 kg per 1 sq. m;
• Depending on the region of cultivation, it can be early-ripening, mid-ripening and mid-late.

Advantages and disadvantages

Vegetable growers highlight the following advantages :

• unique taste qualities;
• excellent shelf life - can be stored almost until the next harvest;
• convenient bulb shape;
• high level of productivity;
• versatility of use;
• peels off well;
• quite resistant to diseases and pest attacks;
• Suitable for planting in different climatic zones.

But there are also some disadvantages :

• the husks fall off during storage;
• planting material is quite expensive;
• large bulbs can shoot;
• The harvested crop does not tolerate dampness well.

Reproduction methods

There are several ways to propagate this onion:

1. Sevcom. You can grow seed material yourself or buy it at a specialty store.
2. Vegetative way. In this case, the teeth that form on adult bulbs are used - they are carefully cut off, germinated and planted in the soil.

Characteristics

The Bamberger onion variety has become a major breakthrough in the world of crop breeding. Taste, ability to be stored for a long time, ease of cleaning - this vegetable has a lot of advantages. For a long time, the primacy was occupied by red-scaled (Red Baron fits this description) and white-scaled onion varieties. The Bamberger variety is superior to them in many respects. The characteristics of a bow can be divided into several groups:

1. External form. The fruits are medium-sized (up to 100 g), round, elongated, with milky-white pulp and yellowish-brown skin. More elongated at the final stage of ripening than some salad varieties.
2. Terms of ripening and harvesting. Depends directly on the growing region. According to the rate of growth of green feathers - early ripening, according to the rate of formation of the underground part (turnips) - mid-ripening, mid-late.
3. Taste qualities. Aromatic burning notes, lack of pronounced bitterness. Tastes like traditional shallots. The taste is milder, more sweet than bitter. Not as hot as the Hercules onion.
4. Storage. The neck practically does not rot. It is distinguished by its good ability to “lie” for a long time - until a new harvest, without drying out (unlike many salad varieties that can survive after harvest until January). This article will tell you how to store onions in winter.

Preparing for planting onion sets

If you bought Bamberger onion sets, you should immediately dry them well so that they do not spoil. In the case of independent cultivation, it is first kept for two or three weeks at a temperature of +20 °C, and the day before planting it is moved to a place with an air temperature of +35-40 °C. Warming the bulbs this way will improve their germination and prevent the formation of shoots.

If for some reason it was not possible to warm up the onion, immerse it in hot water for 20 minutes before planting. To stimulate further growth of onions, they can be processed in an appropriate composition. It is best to use "Rost-1" or "Gumisol". To disinfect the seeds, they are immersed in a solution of potassium permanganate or copper sulfate. The purchased one usually does not need this measure.

Landing

Before planting Bamberger, read the planting rules - how to prepare the site and the planting material itself.

Conditions

It is best to plant Bamberger onions on sandy loam soils, and choose a place that is well lit and without drafts. This variety is planted before winter or in early spring. If planting is carried out in winter, then select the smallest bulbs.

Also, when growing this variety, follow the rules of crop rotation - in the place where the onion grew, it cannot be planted for 3 years. It is better to select those places where legumes, tomatoes or cabbage grew in previous seasons. An excellent neighbor for Bamberger is carrots.

Soil preparation

Before planting onions, prepare the soil - dig up the soil and add fertilizer, as the soil must have a loose structure with a sufficient amount of nutrients. To do this, follow these steps:

• carry out weeding (to a depth of 2-3 cm);
• remove all weeds;
• if there are more than 5 perennial weeds per 1 square meter growing on your site. m, carry out chemical control against them - use Roundup and Hurricane herbicides (30 ml per one hundred square meters);
• scatter organic fertilizers over the soil surface - rotted manure or compost (from 5 to 9 kg per 1 sq. m);
• a few days after fertilizing, plow the area - the optimal depth is 15-18 cm;
• level the plowed area using agricultural implements - if once was not enough, then repeat the harrowing;
• Divide the prepared soil into holes (the number depends on the scale of planting).

Preparation of seed material

Since there are 2 methods of growing Bamberger, there are also several preparatory features for preparing seed material.

Preparing the sets

Dry the purchased material by placing the bulbs in a warm room. Even if you grew the seed yourself, still warm it up before planting.

Warm up the planting material gradually:

• keep it in a room with an air temperature of about +20 degrees for several weeks;
• a day before planting in the soil, transfer the seedlings to a room where the temperature will be 15-20 degrees higher.

This speeds up the germination of onions and also prevents the appearance of arrows. If you do not have time for such a lengthy process, you can speed it up by dipping the bulbs in hot water for 15-20 minutes before planting in the ground. Also, to accelerate growth, stimulating drugs are used - Rost-1 or Gumisol (instructions for use are on the package).

To prevent diseases and pests, treat the seedlings with a solution of potassium permanganate or copper sulfate, and before planting, check them again to make sure that they are free of various defects - traces of rot, mold, etc.

The set should be dense, golden in color and rustle in your hands. It’s good if all planting material is approximately the same size. The most suitable set size is 2-4 cm. If the size is smaller, the bow will not give the desired result; if it is larger, it may shoot.

Planting seedlings for winter is carried out 20 days before the onset of frost. Furrows 3-4 cm deep are made on the site, and the distance between them is 20-30 cm. The seedlings are planted at intervals of 8-10 cm, after which they are covered with soil and mulched.

Preparing and planting seeds

If cultivation is carried out not by bulbs, but by seeds, then they are also prepared for planting:

1. Sort through the seeds, separating out any empty, damaged or rotten ones.
2. Before sowing, immerse the seeds in a solution with growth stimulants - take Vympel or Emistim for this. To prepare a solution, just add 5 ml of growth stimulants to 5 liters of water.
3. Immerse the seeds in this liquid for 24 hours, and then immediately plant them in previously prepared holes.

When sowing seeds, furrows are made to a depth of 5-7 cm and watered abundantly. The distance between them is 15 cm. Before sowing, put rotted manure (50 g) and superphosphate (10 g) at the bottom of the furrows, after which the seeds are sown to a depth of 2-3 cm (3 g per 1 sq. m). Then fill the finished rows with soil and lightly compact the soil.

Landing dates

In different regions, the timing of planting seedlings differs:

1. In Siberia, seedlings are planted in open ground at the end of May. Monitor the temperature before planting - it should be no lower than 8-10 degrees.
2. In the Urals, seedlings are planted around mid-May. As in Siberia, wait until the soil temperature is +8-10 degrees.
3. The optimal time for planting seedlings for central Russia is mid-April - early May.

Agrotechnical recommendations

Planting material for the variety is offered by many foreign and domestic producers. For ease of planting, seeds are produced in granulated or pelleted form, as well as placed on special belts.

Original Dutch seeds from Bejo are more expensive, but they undergo special training, which guarantees fast and friendly germination; stimulation of growth in the early stages; plant resistance to weather stress and diseases; uniformity of products and improvement of the taste of the bulbs. According to those who planted this onion, the descriptions of the plant and images of the heads placed on the packaging of Dutch companies coincide with the result; re-grading almost never occurs.

In small summer cottages, many vegetable growers prefer to grow Bamberger onions from seeds obtained on their own, and to simplify sowing, they stick them on ribbons of rolled toilet paper. Fresh “homemade” seeds are guaranteed to have high germination rates. They can be sown both in spring and autumn. The bulbs grow smaller in size than with the seedling method, and gain an average of 60-80 g.

It is recommended to sow when the ground is still wet from melted snow, and the average daily air temperature is consistently above +5 ℃, that is, during the day about 10-12 degrees Celsius, and at night from 2 to 5 (for the middle zone, the optimal period is the first ten days of May). The beds are spilled with warm water, and then furrows no more than 3 cm deep are laid on them at a distance of about 15 cm from each other. The bottom of the grooves is dusted with ash.

Nigella is sown not very thickly, at intervals of 4-5 cm, sprinkled with earth, peat or sand, and the bed is mulched

More compact planting leads to the formation of unmarketable bulbs, and also increases the risk of plant damage by pests and diseases. The variety is prone to downy mildew, and is threatened by the onion fly and the secretive proboscis.

Pre-prepared (soaked or germinated) seeds do not require additional watering - the first shoots will appear on the surface in a week. But dry ones need to be watered, and they will sprout no earlier than in 10 days. Basic agrotechnical measures, including weeding, watering, regular loosening of the soil, and fertilization are similar to the standard care rules recommended for growing onions from sets.

According to reviews, “Bamberger” onions show excellent qualities when grown through sets planted before winter. Planting sets in the fall has a number of advantages: saving time in the spring, the first “greens” can be tasted 1-1.5 months earlier than with spring planting; onions grow hardy, are resistant to diseases and practically do not shoot. Sets are usually planted a month before the onset of stable frosts, in October - November. As practice shows, it is better to delay the deadlines a little than to plant too early.

To minimize bolting of plants, the smallest specimens are planted first, and the Bamberger onion sets, characterized by medium size, are planted a little later

With the beginning of feather lodging, when the heads are already formed and the outer scales have acquired a straw-yellow color, they begin harvesting. If the soil is dense, to dig up the onions, it is enough to arm yourself with a garden fork. Like most sweet and semi-sharp varieties of onion plants, the Bamberger crop can be stored for no more than 4-6 months after harvesting.

Rules of care

Planting onions is not everything. Next, some agrotechnical measures are carried out to ensure that the harvest is successful.

Watering

Watering is carried out throughout the entire period of active growth of the onion, until the turnip is finally ripe. The frequency of watering depends on several factors, but the main one is weather conditions.

Moderation and regularity of watering are important - Bamberger onions need plenty of water 2 weeks after planting. Irrigation is carried out with settled water (5 liters per 1 sq. m). After this, moistening is carried out as the top layer of soil dries.

At first - 2 times a week, then, from mid-summer, the frequency of watering decreases to avoid waterlogging of the soil. It is very important to completely stop watering 2 weeks before harvest.

Loosening

This procedure is carried out so that the plant receives a sufficient amount of oxygen. Loosening is carried out at least once a week.

If you add mulch under the onions, you can do without loosening. Peat, sawdust, and rotted straw are suitable as mulch.

Weeding

Weed as soon as you notice weeds emerging. The main thing in this procedure is the complete removal of weeds before they take root. Weeding depth is 2-3 cm.

Feeding

With the appearance of the first shoots, it is time to fertilize the plant. During the season, feed onions three times according to the following scheme:

• on the 15th day, add a solution of chicken manure at the rate of 10 liters per 1 square meter. m of land;
• after 21 days, apply nitrogen fertilizers at the rate of 2 tbsp. l. urea per 10 liters of water;
• after another 21 days, the soil is watered with potassium supplements (2 tablespoons of superphosphate per 10 liters of water).

Disease and pest control

Onions are quite resistant to diseases. To prevent them and strengthen young individuals, treat them twice with copper sulfate and copper oxychloride. The first time - when the feathers reach a length of 20 cm, and the second time - in mid-summer during the period of active growth.

Bamberger is attacked by the following diseases:

Also, the Bamberger onion variety can be attacked by the following types of insects or pests:

Basic growing rules

Soil preparation

The Birnformig variety grows well in fertilized sandy loam soil or light loam.
It is advisable to select a site that is not shaded, with good natural drainage. Previous varieties must be:

• green manure;
• tomatoes;
• peas;
• pumpkin;
• cabbage.

The soil begins to be prepared in the fall:

1. The soil should be well dug up with added organic fertilizers, which can be used as rotted manure.
2. In spring, a small amount of nitrogen fertilizer is applied to the soil, but not deeply, so that the weak root system of the plant can reach it.

Planting by seeds

Birnformig onion is a late ripening variety. This variety can be grown from seeds only in the southern regions of Russia under favorable weather conditions.

1. For planting, grooves with a depth of 5 to 7 cm are cut with a hoe. A distance of 15 cm is left between the furrows.
2. A thoroughly mixed composition of 5 parts of rotted manure and one part of any superphosphate fertilizer is distributed over the entire bottom of these depressions (it is advisable to use monophosphate with a phosphorus content of up to 20%).
3. Water the grooves with warm water, after which the seeds are placed no deeper than 3 cm. Seeds are consumed at the rate of 3-4 g per 1 square meter. m.
4. The grooves are filled with earth, but are not compacted.
5. Since sowing is best done in early March, it is advisable to cover the beds with plastic film before the first shoots appear.

Bulbs

It is better to buy onion sets made in Holland.
If it is not known in what conditions the product was stored, immediately after purchase the sets must be dried. Before planting, it is better to store the sets at a temperature no higher than 20°C, and the day before sowing, the bulbs should be heated on a stove or radiator to +35°C. Onion sets bought in a store usually do not need pre-planting treatment, but if there is no heating at your summer cottage, the sets can be warmed up by dipping them in a hot solution of potassium permanganate for 15-20 minutes. For better growth, experienced gardeners advise treating the seed with Humilos.

1. Furrows for sowing are made to a depth of no more than 5 cm, so that after adding rotted manure and filling it with soil, the top of the sowing is not covered with soil.
2. The seedlings are planted at a distance of 10 cm, and a distance of 20 cm is left between the beds.
3. After planting, the soil is mulched with hay or sawdust.
4. On top, as when sowing seeds, you can put plastic film until the first shoots appear.

Care

Many gardeners have already appreciated the Birnformig variety for its ease of care. But to get a good harvest, it is necessary to carry out general agrotechnical measures.

• If the soil was well prepared in the fall and mulched after planting, then weeding and loosening can be done once a month without leaving uprooted weeds in the garden bed.
• At the beginning of the growing season, watering is carried out once every 3-4 days, taking into account natural precipitation (the soil should not be over-moistened). In the second half of the growing season, the number of waterings is reduced to once a week, and 3 weeks before the expected harvest (late August - early September), irrigation is stopped completely, allowing the bulbs to ripen well.
• When feeding this variety, it is better to combine organic and mineral fertilizers according to the following three-time scheme:
  1. the first feeding is carried out 15 days after planting, using solutions of mullein or chicken droppings;

  the second feeding is carried out 20 days after the first using nitrogen fertilizers (ammonium, sodium, calcium nitrate, ammonium sulfate and carbonate, ammophos or urea);

• the third is carried out 20 days after the second using superphosphate and mineral fertilizers containing potassium.

After this, the Birnformig variety is no longer fed.

How to harvest and store crops?

After receiving the harvest, your task becomes its preservation. When digging up onions, do not cut off the feather, as it can later be used to tie the vegetable in bunches or weave braids.

As soon as the harvesting is completed, the onion heads are sent to dry in a warm, well-ventilated room. Recommended temperature for drying is +30 degrees. If the weather is nice and sunny, then dry them right outside, placing the heads on a prepared tray.

Before sending the onions to the storage location, each onion is inspected, since if there are at least a few units with rot, this will ruin the entire harvest.

It is recommended to store vegetables in the basement, the temperature there should be +3-10 degrees, and the humidity level should be 70%. If there is no basement, then an insulated and glazed balcony will do.

It is good to store onions in:

• wooden or plastic boxes with holes made;
• wicker baskets;
• cardboard boxes with perforations;
• in mesh bags.

Variety Bamberger - how to grow in the country?

The skin of the Bamberger variety is yellow-golden in color. The pulp is very juicy and white in color. This variety is resistant to bolt formation, and if the onion is stored correctly, it will retain its taste until next year. In order to get a good harvest, you need to be very careful when choosing planting material. If the seedlings have any defects or traces of rot and mold, then such material cannot be planted. The best size for planting is 2 - 3 centimeters. Material up to a centimeter will not produce large fruits, but sets larger than 5 centimeters will immediately go to waste. Good planting material should be golden in color and rustle when poured.

Before planting onions you must:

• Warm up the seeds. To prevent onions from going wild, you need to warm up the seed before planting. This is necessary in order to start growth processes. You need to warm it up in the sun or near a radiator. This should not be done in a hotter place. As soon as the ground warms up and the temperature is at least 12 degrees, you can plant the seedlings. A few hours before planting, it is worth soaking the planting material in a solution of manganese or vitriol, or in a regular salt solution. This is necessary in order to destroy pathogenic microorganisms “dormant” under the skin of the plant.
• Harden the planting material. Experts believe that onions produce the best harvest when they are planted in winter. This is usually done 2-3 weeks before the onset of cold weather. Such planting material manages to take root before the cold weather, but does not have time to take root. During the winter, onions develop good immunity, and they absorb enough moisture to produce a juicy and tasty harvest.
• Prepare the soil. Before planting, the soil must be dug up and fertilizer applied. And be sure to remove all weeds. Planting material should be buried to a depth of 3-4 centimeters. The distance between the bulbs should be at least 10 cm. And between the rows it should be up to 20 cm. Then the plants will develop freely and you will get a good harvest.
