Tomato De Barao black belongs to a popular group of varieties that differ only in the shade of the skin. It is officially included in the state register of the Russian Federation, it is recommended for growing on personal household plots, and it is not very common on farms. The unusual color of the fruit gives it a special appeal.
Breeding history
The variety was registered in 1999, after passing tests. Its selection was carried out by OOO GISOK in Moscow, with the participation of a group of experienced breeders.

It is covered with green shoots, the leaves are darker. The inflorescences are simple, they are laid above 9-11 leaves, then alternating through 3. The peduncle is formed with an articulation.
The main qualities of the fruit
The color of a ripe tomato is unusual, purple-brown. Fruits are lightweight, weigh up to 58 g, ovoid. The skin is smooth, with dense flesh underneath.
Taste characteristics
De Barao black tomato has a good taste. It is used in salads and cooking, thanks to its small size, it can be preserved whole. The high sugar content gives the fruit a sweetness.
Ripening and fruiting
The harvest begins in August-September. A late-ripening tomato needs 115-120 days to fully ripen from the moment of germination. But his fruiting is distinguished by its abundance and duration.
Yield
De Barao black yields up to 8 kg / sq. m. This is above average. The variety is considered to be high yielding.
The timing of planting seedlings and planting in the ground
Sowing seeds for greenhouse cultivation should be started in advance. This is usually done no later than 70-75 days before the expected transfer of plants to open ground. It is recommended to start sowing in mid-February. Transfer to greenhouses occurs at the end of April.
Growing tomato seedlings is an extremely important process, because it largely depends on whether the gardener will be able to harvest at all. All aspects must be taken into account, from seedbed preparation to planting in the ground.
Landing scheme
The standard scheme involves placing no more than 4 bushes per 1 m2.
Growing and care
Tomato De Barao black is suitable for planting in plastic greenhouses and open ground. Tall bushes need a mandatory garter, removing unnecessary stepsons. When growing in a greenhouse, the shelter must be made as high as possible. Shoots continue to grow throughout the growing season.The formation of a bush is recommended in 1 or 2 stems, this is how abundant fruiting is ensured.
For disembarkation, it is not necessary to choose sunny, well-lit areas. Plants grow well in the shade. But they need protection from the wind, otherwise branches may break in the open field. The soil should be loosened and fertilized in advance. By the time the tomatoes are planted, the soil should warm up well.
Pinching of young plants is performed after at least 5-7 flower clusters have been formed. Grassing is continued throughout the growing season, repeated weekly, manually, to avoid the transmission of diseases through the tools. Upon completion of the formation of the fruits, complete removal of the leaves under the brushes must be performed in order to preserve the strength of the bushes for their ripening.
When grown in open ground, the plants are mulched, insulating the root zone. Otherwise, tomatoes are well acclimatized, successfully tolerate fluctuations in night and day atmospheric temperatures.
Tomato De Barao black responds well to fertilizing and watering. Moisten the soil in the greenhouse no more than 2 times a week, in cool morning or evening hours. Every 14 days, the root zone is loosened, followed by a mulch change. Fertilizers are applied three times during the season - first organic, then minerals. During the flowering period, spraying with a solution of boric acid (10 mg per 1 liter of water) will be useful.
A plant needs different micronutrients at each stage of growth. All fertilizers can be divided into two groups: mineral and organic. Folk remedies are often used: iodine, yeast, bird droppings, eggshells.
It is important to observe the rate and period of feeding. This also applies to folk remedies and organic fertilizers.
Disease and pest resistance
In terms of resistance to late blight, the variety is among the best. He is weakly susceptible to this disease, as well as to the top rot. Tomato is prone to cladosporium infection in greenhouses. Vertex rot occurs when there is insufficient nutrition. As a treatment and preventive measure, spraying with a solution of calcium nitrate is used.
Sometimes De Barao black is affected by black spot. If signs of this disease are detected, it is necessary to process the bushes. Suitable drug "Fitolavin" or similar options. Among the common pests on plants, slugs can be found - they are collected by hand, and also destroyed by spraying with a solution of mustard powder. Also, the Colorado potato beetle may appear on the bushes, which is fought with the help of chemicals and physical destruction.
Growing regions
The variety is zoned for cultivation in most regions of Russia - from the Urals to the Far East. It is successfully cultivated in the Moscow region, in the Leningrad region. In the Central Black Earth Region and in the North Caucasus, cultivation is carried out without a film cover.
Review overview
According to gardeners, De Barao black has obvious advantages over other subspecies of this variety due to its very high yield. Also, gardeners pay attention to the unusual and very bright taste of the fruits, pleasant when they are eaten. The neat, beautiful shape also gives them a special appeal. Excellent keeping quality allows you to keep tomatoes for a long time at home. In the process of growth, the fruits do not crack, retain the smoothness and integrity of the shell, are suitable for subsequent freezing.
Despite the recommendations of breeders to maintain a plant of 1-2 stems, most gardeners prefer to leave 3-4 main shoots. This reduces the climb activity. Summer residents also practice planting stepchildren from the first shoots - they tie their brushes much lower, grow more slowly, gaining no more than 1 m, the ripening of the crop accelerates. The relative disadvantages include the late onset of fruiting in the open field - they ripen by October.
