The variety with bisexual flowers belongs to the table. Vigorous bushes require timely pruning. In the plant, the percentage of fruiting shoots is 55-65. The fruiting factor is 1.1-1.3. On one shoot, the number of inflorescences is 1.3.

Ripening period

Dunav belongs to the early varieties in terms of ripening. The fruits are harvested in 115-125 days.

Bunches

Cylindrical bunches can reach 800-1000 grams in weight. The density of the fruits is average. Peeling is observed, but insignificant and usually when the plant does not have enough sun.

Berries

Bright red grapes have a sugar level of 160-180 g / dm³. The acidity level reaches 5-6 g / dm³.

The dense, crispy flesh is highly prized. The fruits have an elongated oval shape. The berry weight can be from 8 to 10 grams.

The tasting score is 8.2 points.

Taste

Harmonious taste is another advantage of the described variety.

Yield

The yield level is 130-140 centners per hectare. Thus, Dunav is considered a high-yielding plant.

The choice of planting material
Experienced gardeners recommend that beginners take cuttings and seedlings from those who made them from their vines and are professionally engaged in the production of such material.
You can evaluate the quality by cutting off a small amount of bark. When growing a bush from a cuttings and observing the rules of agricultural technology, survival rate is about 90%, the high quality of the plant is practically guaranteed. It is possible to control the development of grapes at all stages.
Subject to the rules of agricultural technology, survival rate is about 100%. The seedlings must be healthy. Pay attention to the absence of blisters, growths, or other signs of disease.

Growing features

You can grow grapes on a wide variety of soils. However, a loamy soil with good organic matter content and good drainage is considered the most suitable for commercial grape growing.

For good vegetative growth, the soil should have a pH ranging from 6.3 to 7.3. Note that the cultivation of grapes on saline soils affects its growth.

The easiest way to propagate grapes is to grow them from deciduous cuttings. However, other methods are also used:

  • seeds;

  • layering;

  • planting stock;

  • graft.

Landing

Preparing the soil for grapes is an important task. It is desirable that the site is on a slight slope, cleared of weeds. This can be achieved by deep plowing 3-4 times.

If there is a deficiency of trace elements in the soil, then it should be additionally fertilized during the last plowing. It's a good idea to add the cake along with well-rotted manure.

For growing grapes, a distance of 3.00 x 1.50 meters, 2.50 x 1.50 meters and 2.75 x 1.50 meters is sufficient for growing more than 2500 plants per hectare of land.

For planting, dig holes measuring 90 cm x 90 cm x 90 cm and fill them with well-rotted manure along with the soil.

For good soil subsidence in the planting pits, light watering should be carried out.

Landing features
In order for the vine to give a signal harvest after 3 years, it is necessary to take into account many factors - from the type of soil on the site to the nearby plants.

Pollination

Pollination is not required.

Pruning

Pruning is carried out at the rate of 8-10 eyes per vine. The number of eyes per bush should be 35-40 pcs.

Pruning is one of the main grape care procedures. Depending on the purpose of pruning and the type of plant, the appropriate type of formation is selected.

Watering

Grapes need water, so watering is done regularly at all stages of growth. Irrigation of grapes with a drip irrigation system has many advantages. Waterlogging should be avoided, as this leads to numerous diseases.

Irrigation schemes
In order for the berries to be large and juicy, it is necessary to organize full watering and feeding. All standards must be adjusted for weather conditions and the rate of evaporation of the liquid.
With a frequent watering scheme, it is recommended to moisturize once every two weeks (that is, twice a month during flowering and the appearance of berries) so that the earth is saturated 50 cm deep so that the plant does not switch to superficial (dew) roots. This amount can be reduced by mulching the crop with straw.
With a rare irrigation scheme, choosing the age and ripening period of the grapes, you can use the standards presented in the table in another article.

Top dressing

When growing grapes, nitrogen, phosphorus and potassium must be added annually. Biofertilizers and liquid pesticides can help improve the quality of the grapes.

Spraying with humic acid in a sugar solution is useful.

Frost resistance and the need for shelter

The frost resistance of this variety is low, only -18 degrees Celsius. Shelter for the winter is a must. In this case, the vine is first removed from the trellises, then covered with material or spruce branches.

Shelter for the winter is a very important step for the preservation of many grape varieties after wintering.

Diseases and pests

Insects can attack the vineyard, so preventive treatment with insecticides is carried out twice. Fungicides help with powdery mildew, mold and rot.

Storage

The Danube is perfectly transported and keeps its presentation. Can be stored in refrigerators for a long time.
