Tomato Maryina Roscha

Maryina Roshcha is a representative of early maturing hybrids, very generous in harvest, unpretentious, stable and strong. If you want to get in your greenhouse a whole grove of real tomatoes that bear fruit all year round, then use this win-win option.

This hybrid variety appeared thanks to the persistent work of the employees of the well-known domestic company Uralsky Dachnik. The authors - T. V. Steinert, N. Teplova, A. V. Aliluev, L. M. Avdeenko, V. Yu. Poldnikova managed to create a productive culture for greenhouses, with the ability to harvest all year round. The variety has been approved for use since 2020, but is not yet in the State Register.

The bushes of this plant are indeterminate, tall, reaching sizes up to 1.8 m. The stems are powerful and strong enough, forming many lateral processes.

The leaves are medium in size, light green in color, with typical shapes and a fragrant aroma. When fruit appears, we recommend removing the lower leaves to increase the feeding intensity.

According to its parameters, Maryina Roshcha is ideal for growing in protected soils (greenhouses).

Since the culture does not survive low temperatures well, the authors took into account the need to create other positive characteristics, therefore Maryina Roshcha received a number of significant advantages:

• high percentage of seed germination;

• the possibility of growing throughout the year;

• the ability to adapt to different conditions of development;

• immunity to lack of lighting and temperature fluctuations;

• a high degree of resistance to typical diseases of nightshade crops;

• the possibility of off-season fruiting;

• high yield from 1 bush;

• synchronicity of fruit ripening in 1 hand;

• excellent commercial properties;

• versatility of fruits in application;

• durability during transportation;

• excellent keeping quality of fruits without signs of spoilage.

Minuses:

• culture needs shaping and tying;

• indeterminacy requires timely pinching of the tops;

• impossibility of self-collection of seeds;

• poor suitability for growing in open soils.

When the necessary conditions are formed, the crop can bear fruit at any time of the year, and therefore it is recommended for growing for sale.

The fruits of the culture are attractive. Up to 9 pieces can be formed in one brush. As they mature, the color changes from green to deep red. The peduncle has an articulation, and a green speck is located around it. The greatest weight of the fruit is about 200 g, on average they ripen with a weight of 150-180 g. Their configuration is rounded, slightly ribbed, with large sizes, somewhat flattened. Consistency of medium density, fleshy. Taste properties are excellent.

The fruits of Maryina Roshcha are universal - gastronomic and other characteristics allow them to be used in salads, in hot and cold dishes, for whole-fruit preservation.They perfectly tolerate long-term transportation, with practically no damage to their commercial qualities.

The fruits of the Maryina Roshcha tomato are characterized by good commercial properties; they tolerate long-term transportation without damage.

The consistency of the fruit is sugary, the taste is pleasant and delicate, slightly sour.

A characteristic feature of Maryina Roshcha is abundant and prolonged ripening and fruiting, of course, provided that the required temperature and care are observed.

The variety is considered high-yielding, since up to 5 kg of tomatoes are obtained from one bush. According to the testimony of breeders, up to 11 kg or more of fruits are removed from 1 m2, with a planting density of 3 pcs. per 1 m2.

Sowing the seed stock is carried out no later than 1.5 months before planting in closed soil. Sowing dates fall at the end of February, while planting is carried out in mid or late April.

Landing in greenhouses is performed taking into account the fact that 1 sq. m should be placed no more than 3 bushes.

Sowing is carried out in pre-prepared containers. The soil is prepared independently (using garden soil, peat, rotted compost in equal proportions, with the addition of 1 tablespoon of wood ash, a little calcium sulfate and superphosphate). Often, ready-made mixtures are bought in special stores.

Used containers must be disinfected by pouring boiling water over them. Seed stocks should not be soaked, they can be sown directly into moistened soil - an approximate planting depth of 1.5 cm, at a distance of 5 cm. To improve germination, containers are covered with foil material to obtain a greenhouse effect.

As soon as the first shoots appear, the containers should be placed in a place with a slightly low temperature to stop the growth of seedlings in height.

When 2 full-fledged leaves are formed, the young animals are transplanted in separate containers. At the end of the two-week period after this procedure, in order to strengthen the roots, top dressing is performed (1 tablespoon of nitrophoska is diluted for 10 liters of water), for 1 bush - 200-250 ml of solution.

In the case when lowering the temperature regime has not fulfilled its task, during the transplantation the seedlings are deepened without touching the cotyledon leaves.

After transplantation, a stable three-day temperature regime should be observed: +22 during the day and +18 at night. When the seedlings get stronger, the temperature should be reduced by 2 degrees.

Irrigation is performed once a week, abundantly and until the soil is completely filled.

After 20 days, the bushes are transplanted again, after which they are placed in a darkened place for 2 days, and after 2 weeks they are fed again with a solution (for 10 liters of water - 2 tablespoons of wood ash and 1 tablespoon of superphosphate) per 1 seedling - 250 ml.

Before planting in greenhouses, the seedlings are prepared in 2 weeks by placing them outside (for a few minutes) and gradually increasing the hardening duration. And also the lower leaves are cut off, and the places of the cuts are covered with wood ash.

The disembarkation is carried out according to the landing scheme.After that, the care scheme remains identical to the care of other garden plants - irrigation, loosening and weeding.

The bushes are molded into 2 trunks, removing all stepchildren. In this case, 1-1.5 cm is left to prevent the formation of new ones. Then a garter and pinching are performed.

The growth of bushes should be limited when about 9 brushes are formed.

Maryina Roshcha is distinguished by a strong immune system, anchored at the genetic level. The culture is resistant to the typical nightshade diseases developing in closed growing areas. Fruits are reliably protected from viral and fungal infections, therefore, during cultivation, there are no such problems as regular professional activities. However, planned activities must be carried out. A spraying procedure with a weak manganese solution can be envisaged.

As for pests, a slug remains dangerous. Protection against it is realized by regular ventilation of greenhouses.

Culture copes well with temperature stresses and other vagaries of nature.
