Features of planting and growing

The quality and quantity of the crop depends on many factors, including the correct preparation of planting material and soil and compliance with the timing of planting onions.

Presowing preparation

The purchased onion sets for 2-3 weeks are laid out in a warm room at a temperature of + 20 ... + 22 ° C with good ventilation for drying. This helps to avoid rotting the inside of the bulbs.

To eliminate arrowheading, to kill spores of fungi that may be present on the surface, and to speed up the formation of green leaves and roots, in 24 hours before planting the bulb warm up:

• the seed is placed in a container of a suitable volume;
• pour water heated to + 35 ... + 40 ° C;
• close the container with a lid, wrap it up and leave for 5-6 hours.

Reference. For additional disinfection, the seedlings are soaked for 20-40 minutes in a solution of potassium permanganate or copper sulfate.

The soil is prepared with autumn: cleaned of weeds, treated with copper sulfate (diluted with 1 tbsp. l. funds in 10 liters of water and water the earth at the rate of 1-1.5 liters per 1 sq. m), and watered abundantly before frost.

In the spring, the soil is fertilized. Mineral or organic fertilizing is chosen depending on the type of soil:

• loams: 3-4 kg of humus, 5 kg of peat, 2 tbsp. l. superphosphate and 1 tsp. urea per 1 sq. m;
• clay soil: 6 kg of humus and peat, 1 tsp. urea and 1 tbsp. l. superphosphate per 1 sq. m;
• peat bogs: 5 kg of compost or humus, 1 tsp. urea and 1 tbsp. l. "Nitrofoski" and superphosphate per 1 sq. m;
• sandstones: 10 liters of compost or humus, 2 tbsp. l. superphosphate, 1 tbsp. l. "Agricola" and 20 liters of loamy or clayey soil per 1 sq. m.

The beds are dug onto a shovel bayonet, then covered with foil and left for 5-6 days.

Ground requirements

Bamberger prefers light, fertile soil with good aeration and moisture permeability. The permissible acidity for mineral soil is pH 6.5-7, for peat soil - 5.5-6.5.

Timing, scheme and landing rules

There are two options for planting sevka Bamberger: wintering (in the third decade of October) and spring, when the soil warms up to + 10 ° C (in mid-April - early May).

Landing before winter:

1. Prepare the beds at a distance of 25-30 cm from each other.
2. Make planting furrows in them 8-10 cm deep.
3. Place the bulbs in the furrows so that the distance between them is about 10 cm.
4. With the onset of persistent frost, cover the beds with a thick (10-15 cm) layer of hay, straw, fallen leaves or sawdust.

After the snow melts, the mulching layer is removed from the garden. This is usually done in the second decade of March, but if frosts continue, the mulch is left until they pass.

When the soil dries up, it is loosened. Shortly thereafter, onion feathers emerge from the soil.

For spring planting, they dig up the earth on a half bayonet of a shovel and level it with a rake. Next you need to:

1. Prepare beds with a distance of 25-30 cm between them.
2. Make planting furrows in them 3-5 cm deep.
3. Water the furrows 30 minutes before planting the seedlings (1 liter of water per 1 m of the furrow).

In the spring, you can also sow onion seeds, after soaking them for a day in a solution of a growth stimulator, for example, "Epina".

Growing features

The planting site for Bamberger bows should be well lit, protected from gusty winds and located on a small hill. In the lowlands, moisture often stagnates, which provokes rotting of the bottom of the onion.

It is important to consider the rules of crop rotation: peas, soybeans, beets, cabbage and cereals are considered the best predecessors of onions.

Reference. Onions can be planted in the same place once every 3-4 years.

Bamberger bow is unpretentious in care. At the same time, compliance with the basic agrotechnical norms and rules is necessary for him in the same way as for other varieties.

Watering mode

The need for irrigation is determined by the condition of the soil: it is watered when it is completely dry to a depth of 10 cm.

The procedure is carried out in the morning, because during the evening watering the onion will not have time to dry out completely, and the accumulation of moisture on the leaves leads to the development of fungal diseases.

Particularly abundant watering - every 2-3 days - is required during the month of cultivation. Then it is gradually reduced - up to 1 time in 10 days. 2-3 weeks before harvesting, they stop completely so that the onion ripens well.

Loosening the soil and weeding

The soil is loosened and weeded every 10-14 days or more. It depends on the growth rate of the weed.

Loosening improves oxygen access to the bulbs, which has a positive effect on the quality and quantity of the crop. Removing weeds is necessary to ensure that they do not take nutrients from the soil.

Important! Mulch-covered beds do not need these treatments.

Top dressing

Fertilizers are applied three times according to the following scheme:

• 14 days after planting onions - a solution of chicken manure at the rate of 10 liters per 1 sq. m;
• after 3-4 weeks - nitrogen-containing dressings;
• after another 3-4 weeks - potash fertilizers.

Disease and pest control

To prevent the development of diseases and attacks of pests, plants need to be treated with copper chloride during active growth or copper sulfate, when the length of the feathers reaches 15-20 cm.

Growing difficulties

When cultivating this variety, the following problems may arise:

• throwing seed arrows when planting onions in cold ground;
• drying and lodging of feathers due to non-compliance with the rules of agricultural technology (shallow planting of seedlings, lack of nitrogen in the soil, lack of lighting);
• yellowing and drying of leaves due to the attack of onion flies.

Harvesting and storage

Lodging of feathers testifies to the ripening of onion heads.

How and when to collect

The crop is harvested in August - September, carefully digging in the bulbs with a shovel and pulling them out of the ground with your hands.

Storage features and keeping quality of the variety

After harvesting, the onions are dried in a well-ventilated room at an air temperature of + 30 ° C.

After drying, the roots are cut off and the bulbs are carefully examined: too small are set aside for early use, and the spoiled ones are thrown away.

For storage, onions are placed in wooden or plastic boxes with ventilation holes, wicker baskets or mesh bags and taken out into a dark, ventilated room, where the humidity is 70% and the air temperature is + 3 ... + 10 ° C.

Important! Containers with onions are placed on shelves or pallets. Do not store crops on the floor or near walls.

Subject to the necessary conditions, onions are stored until the next harvest, practically does not deteriorate and does not germinate.

Tips from experienced gardeners

Farmer tips for growing Bamberger:

1. Fill in the soil between the rows with mulch. This will help avoid damage to the bulbs and leaves during tillage and minimize the risk of developing some bacterial diseases.
2. Cover the newly planted plants with agrofibre or spunbond to keep them warm. In addition, the nonwoven fabric hides the smell of onions from pests.
3. Plant carrots nearby to ward off onion pests.
