Tomato Dubrava

Due to their unpretentiousness, Dubrava tomatoes are jokingly called "a culture for the lazy." Tomatoes do not need special care, they can withstand various natural disasters relatively easily, do not require tying, and also a rather time-consuming pinching procedure. At the same time, the variety is characterized by high yields. This is exactly the case when a joke almost completely justifies itself in practice.

The Dubrava (Dubok) culture was created back in 1993 at the Federal Scientific Center for Vegetable Growing. The work was carried out by a team of scientists: A. Agapov, A. Alpatiev, R. Skvortsov, L. Gurkina. The variety was listed in 1997. Recommended for cultivation in open soils, but also suitable for greenhouses. The preferred growing areas are Central and Volgo-Vyatka. It is also planted in other regions.

By its purpose, this is a commercial variety that does not require special care. The culture is early maturing, determinant, giving an excellent harvest after 80-105 days after the emergence of the first shoots. The secondary flowering of the culture starts almost immediately after the appearance of the first fruits.

Bushes are strong, compact, medium spreading, low (40-60 cm). In the case of abundant nitrogen supplements, the bushes stretch up to 70 cm, but this happens to the detriment of the quality of the tomatoes. The leaves are small, with a characteristic configuration for the variety, slightly corrugated, with a light green color. Stepchildren's education is moderate.

Among the advantages of the variety:

• early maturation;
• unpretentious care;
• uniformity of fruits in size;
• compacted consistency;
• simultaneity of maturation;
• excellent transportability;
• no need for pinning and garter;
• the ability to collect your own seed fund.

Minuses:

• average taste properties;
• medium degree of resistance to diseases and sabotage attacks;
• regional restrictions on growing.

Tomatoes are round, often slightly flattened, even or with small edges. Fruit weight - 53-110 g. Some specimens may be larger. The number of tomatoes in one brush is 5-6 pcs. The pulp is firm, medium fleshiness. Fruits of pronounced red color.

The fruits have a sweet and sour taste. It was declared balanced by the originators.

Dubrava is an ultra-determinant variety. In other words, it cannot be pinned. The first brush germinates after 6-7 leaves, and the next one - after 1-2 leaves. Since the fruit is picked up before the appearance of late blight, subsequent preventive measures are minimized. In order to obtain large-sized tomatoes, the pinching is carried out early. The crop is harvested from July 15 to August 20.

The yield in the Central region reaches 133-349 c / ha, in the Volgo-Vyatka region - 224-551 c / ha, and the highest - 551 c / ha (up to 5.5 kg / m2).

The relative unpretentiousness of the culture makes it easy to care for. Sowing for seedlings is carried out in the period from March 20 to 30, and seedlings are planted in the soil on May 10-20. It is advisable not to hesitate with sowing seeds, planting them in a depth of about 2 cm.But it is not recommended to plant them too early, since overgrown sprouts not only take root weaker, but also lose productivity. In the southern regions of the country, growing crops using seedlings is not required. The variety develops well in soils warmed up to 15 degrees.

A typical crop planting scheme is 70 x 30-40 cm, density is 4-5 plants per m2.

The variety shows abundant fruiting on sandy and loamy soils. It is not worth cultivating it in one place for more than 3 years in a row. The best crop rotation options are:

• zucchini;
• cabbage;
• salad;
• parsley;
• legumes;
• cucumbers and onions.

Eggplant or bell peppers are bad options.

In the course of growing seedlings, a dive is performed with two true leaves, which contributes to the high-quality development of the roots of the culture. If the plants are immediately planted in individual containers, then they do without diving.

The seedlings are hardened approximately 7 days before planting in the ground. If you have a desire to plant Dubrava in mid-May, then the plants should spend the first 20-30 days in greenhouses.

Seedlings are fed 2 times for the entire growing period. At the same time, complex fertilizers (Agricola) are used. The first groundbait is carried out 7 days after the dive, and the second - on the eve of planting in open soil.

The culture is planted in open ground after the threat of recurrent cold snaps has passed and the soil warms up to 15 ° C. The variety needs regular and abundant watering. After irrigation, it is imperative to loosen the soil to provide oxygen access to the plant roots. In order to reduce labor costs, the soil near the bushes is mulched with humus, cut grass or dark non-woven material.

In the open field, Dubrava is fed three times: during planting, at the onset of mass flowering and at the beginning of fruit coloring. The culture readily accepts phosphorus and requires nitrogen in moderate doses. This should be borne in mind during feeding, so as not to cause excessive growth of greens to the detriment of fruit formation. In poor soils, before planting seedlings in the holes, it is recommended to pour in a handful of wood ash, and also pour in 200 g of a solution of rotted chicken droppings.

The rationing of the fruits of the variety is mandatory, since the brushes are unnecessarily overloaded with fruits. In the course of rationing, 5-6 of the largest tomatoes are left, and therefore their weight is set within 90-110 g without changing the yield level. It is necessary to water the culture as the topsoil dries up. Watering is carried out in the morning or in the evening: at this time, the heat will not contribute to the formation of a crust on the soil, and the sun's rays will not burn the bushes after irrigation.

Although the variety does not require tying, for especially hardworking gardeners, we note a number of advantages that this procedure gives for low-growing crops:

• the process of leaving is simplified;
• the neatness of the fruits is preserved, their decay is prevented, since there is no contact with the ground;
• when tied, the bushes are better illuminated;
• breaking of stems is excluded with abundant harvests.

Tomato Dubrava shows an average susceptibility to late blight. However, the disease appears rarely, because the fruits ripen early. Resistance to other ailments in culture is also at an average level. When the lower brushes of the plant are located on unprotected soil (especially in rainy season), rot may appear.

Typical preventive measures are quite effective against malicious attacks. In climatically warm regions, when crop rotation is disturbed or close planting with potatoes, it is extremely difficult to grow fruits without damaging plants with the Colorado potato beetle.
