Augusta grapes are considered one of the best varieties for central Russia. This is an early variety with good frost resistance and average yield. The technical grade is used for the production of nectars, juices, dessert and dry wines.

Breeding history

It was obtained in 1998 by the All-Russian Research Institute of Viticulture and Winemaking named after Ya. I. Potapenko when crossing the French hybrid SV 12-309 with the domestic hybrid Kazachka.

Geography of distribution

The North Caucasus region, Ukraine, the southern regions of Russia, for cultivation in the middle lane, it is recommended to cover for the winter. There is information about planting and fruiting in Siberia.

The leaf plate is light green smooth, the petioles are red-brown. The plant grows very quickly, the dense leaves create significant shading. Differs in 100% ripening of shoots. Flowering begins in late May - early June.

Ripening period

The ripening period is 130 days. For the production of dry wine, you can harvest at the end of August. For dessert wines, the bunches are left to hang on the vine until early September.

Bunches

Small, weighing about 110-120 g. Conical in shape, loose in density.

Berries

Small, rounded, dark blue with a characteristic bluish waxy coating. The mass is about - 1.3 g. The pulp is fleshy and juicy, the juice is not colored, there are small bones.

Taste

Sweet and sour harmonious taste with a light nutmeg aroma. Sugar content - 23-27%, acid - 9 g / l.

Yield

The variety is considered high-yielding, brings from 8 to 10 kg per bush, there is information that up to 100-110 centners of berries can be removed from one hectare.

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

The vines must be tied to a trellis or other support. During flowering, it is necessary to normalize the number of brushes on the lash; foliage is removed around the bunches. The plant needs frequent pruning. It is necessary to weed from weeds, loosen the soil after watering, mulch.

Landing

August takes root well. Choose a place on the south side, protected from the wind. Prefers black soil, sandy loam and light loamy soils. They are planted in spring, the air should warm up to +10 degrees. The layout is 3x1.5 m. After planting, the seedlings are covered with a film, when shoots appear in the film, holes are cut.

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

It blooms with male and female flowers. Able to self-pollinate. With artificial pollination, the yield increases several times.

Pruning

The length of the vine should not exceed 180 cm. During the period of pouring the berries, the green tops on all vines are cut off. Some of the leaves are also recommended to be removed - they interfere with ventilation, shade the bunches. Be sure to cut short shoots that are less than 10 cm.

The main pruning is carried out in the fall after the foliage has fallen and the onset of the first frost. On the bush, 20-25 eyes are usually left, cut off by 3-4 eyes.

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

It should be moistened often: not flooding the plant, but providing it with water to the fullest. Water with settled water is the same as the air temperature on the site, about 2 times a week. Watering is stopped 2 weeks before ripening. Do not water during the rains.

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 maturation of the grapes, you can use the standards presented in the table in another article.

Top dressing

The first feeding is carried out in June or early July with a superphosphate solution (200 g per 3 liters of water). The second time - in early August, mixing ammonium nitrate (30 g), boric acid (10 g), potassium sulfate (100 g) with 2 liters of water. The resulting composition is sprayed on the foliage on both sides, sprayed again every other day, but with clean water. This procedure is best done in calm weather. In autumn, they are fed with liquid organic fertilizers.

Frost resistance and the need for shelter

Withstands temperatures down to -25, but gardeners recommend sheltering grapes for the winter in central Russia.

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

Diseases and pests

The variety is resistant to a number of diseases: mildew - 2.5 points, phylloxera - 3.5 points.

May be affected by gray mold or chlorosis. Diseased shoots and leaves are removed and destroyed. To eradicate gray rot, use "Benleit", "Topsin", "Euparen". Processed: after the flowers fall, then before the berries close in the brush, two more times: at the beginning of ripening and 1 month before harvesting.

Against chlorosis, drugs are used "Mikom" or "Antichlorosin". Before flowering, spray with a 0.1% solution, after completion - 0.15%, for the next 2 treatments, use a 0.2% solution.

Fruit rot may appear before harvest. To treat infected areas, a solution of potassium permanganate, a mixture of iodine with potassium or baking soda is used.
