It does not show particular whimsicality, and therefore it is already particularly popular in gardening circles. In this article we will dwell in more detail on the description of the characteristics of the Irina f1 tomato, and also talk about how it can be grown in open ground conditions, as well as in special, pre-prepared premises. This article will help gardeners decide for themselves whether they really like the Irina tomato. And how best to grow it to get the most abundant harvest.

Tomato Irina: variety description

Irina tomatoes are a first generation F1 hybrid; the breeders managed to include all the quality traits in it. Tomato hybrids are more resistant to adverse conditions and diseases, but have one drawback - the seeds cannot be used for planting .
The plant is determinate (has a final growth point, no need to “pin back”). Read about indeterminate varieties here. The type of bush is not standard. Stocky, persistent, about a meter high. The stem is strong, thick and well leafy with several simple type racemes. The leaf is medium-sized, dark green, typical “tomato” - wrinkled, without pubescence. The inflorescence has a simple structure, the intermediate type is the first inflorescence above the 6-7th leaf, the subsequent ones occur with an interval of 2 leaves, sometimes after 1 leaf. One inflorescence produces about 7 fruits. Pedicel with articulation.

Tomato Irina is an early ripening hybrid; the fruits begin to ripen 93 - 95 days after planting . It has excellent resistance to most tomato diseases - tobacco mosaic, Alternaria, Fusarium, late blight. Cultivation is carried out in greenhouses, greenhouses, under film and in open ground.

Outdoor care

The Irina tomato has excellent performance, and therefore most gardeners speak very flatteringly about the results of their cultivation. However, they are the result of hard work while caring for this hybrid.

Watering

Features of watering tomatoes of the “Irina” variety:

• watering must be done directly on the ground (in no case should you pour the leaves, especially in strong sunshine);
• the water should not be too cold (preferably room temperature);
• Watering should be done as the soil dries out (every year the amount of watering can vary significantly).

Feeding

The first application of fertilizers should occur after the 25th day of bush growth. Any organic fertilizer (both store-bought and compost) is suitable as a top dressing; however, the amount of nitrogen that will enter the soil should be reduced. The total number of feedings during the growing season should not exceed 3. It is also important to pay attention to the fact that if there are few sunny days, you need to give more potassium.

Stepsoning

Pinching is the process of forming a bush by cutting off excess shoots. This is a mandatory procedure, because if it is not done, the bush will grow in all directions and will not produce a normal harvest. So, it is advisable to plant the Irina tomato into one, maximum two stems, and this must be done as soon as side shoots appear on the plants. Unnecessary shoots should be carefully trimmed. Thus, the bush will always look neat, and all its strength will go to the fruits, and not to the growth of shoots. In addition to removing green shoots, it is necessary to regularly cut off dried leaves and branches.

Soil care

Weeding is a mandatory daily procedure, along with loosening the soil and watering. After each watering, the soil must be loosened well to ensure even moisture ingress, and also to ensure that the soil does not crack or harden.

For additional protection from drying out, you can mulch tomatoes with pine needles, hay or peat. This will ensure good moisture retention in the ground, but the most rational way to obtain moisture is modern drip irrigation.

Important! As mentioned earlier, you need to think about the garter in advance, maintaining space between crops for installing supports.

Tying up a bush

Tying the bush must be done as it grows. This is done so that the heavy fruit does not break the branches with its weight and bend them to the ground. If this happens, you will not be able to get a rich, ripe fruit. There are many ways of tying, but many farmers continue to come up with more and more intricate designs for this purpose. However, the most common are the two simplest methods:

• thread garter (iron reinforcements are installed at the beginning and end of the beds, between them a dense thread is stretched across the entire bed, and the branches are tied to it);

• iron (wire) frames, which are installed directly next to each bush and serve as a reliable support for it.

Preventative treatment

The Irina tomato is considered a very resistant variety that is rarely susceptible to disease or pest attack. Because of this, there is no particular need to carry out any prevention. However, heavy rainfall can cause late blight. Therefore, in case of a large amount of rain, it is necessary to treat the bushes with Fitosporin, Trichopolum or a solution of wood ash a couple of times with an interval of 2-3 days. When insect pests appear, you should treat the bushes with a soap solution, and if this does not give results, only then resort to chemical insecticides.

Characteristics

The shape is flat-round (flattened at the top and bottom), not ribbed. Size - about 6 cm in diameter, weighing about 120 g . The skin is smooth, dense, thin. Inside the fruit is fleshy, tender, juicy. The color of the fruit when unripe is pale green, when ripe it is dark red. No stains are observed.

You can compare the weight of fruits with other varieties in the table below:

The taste is noted to be good, rich “tomato”, sweet (the amount of sugars is about 3%). There are a small number of seeds, placed in several chambers (more than 4). Dry matter content less than 6%. Stored in dry, dark places for quite a long time . It tolerates transportation without consequences for the condition of the skin and interior.

The Irina tomato variety was bred by breeders of the Russian Research Institute. Registered in the State Register of the Russian Federation for cultivation in garden plots in open ground and under film covers in 2001. Available for cultivation throughout the Russian Federation.

Universal in use, good both fresh (sliced, vegetable salads, sandwiches) and after heat treatment (stews, stews, soups). Suitable for canning, does not lose shape due to high density . Suitable for the production of tomato paste and sauces, juice production is possible.

Productivity is high - up to 9 kg per plant (about 16 kg per m2), up to 5 kg per plant in the first weeks in greenhouses without additional heating. In heated greenhouses, larger fruits are possible; in open ground, accordingly, smaller fruits are possible. Fruit sets well in cold weather.

You can compare the yield of this variety with others in the table below:

Bull Heart

A feature of the Ox Heart tomato is the irregular shape of the fruit (it is narrowed downwards). The plant, according to its characteristics, grows up to 170 cm in height, but after the formation of a certain number of flower clusters, stem growth stops.

Up to 5 kg of red fruits are collected from one bush. In a greenhouse, the yield rate doubles. Using advanced agricultural techniques, it is possible to harvest up to 12 kg of tomatoes per season (400-600 c/ha).

The average fruit ripening time is 4 months. Accordingly, the tomato is classified as mid-season. One bunch produces fruits of various shapes and sizes. Accordingly, they ripen unevenly.

Ripe fruits weigh from 100 to 500 g. They are suitable for eating and canning. Thanks to the taste qualities for which many people value the tomato, Ox Heart makes delicious tomato pastes, leche and sauces.

Features of care

The bush is formed in one of two ways:

• with one stem;
• with two stems.

The second stem is formed from the first stepson that appears on the young bush. The remaining stepsons are removed. They have a negative impact on the development of the bush and the ripening period of fruits.

Breeders have worked hard to improve this variety of tomatoes. Today there are subspecies of Oxheart, the fruits of which are colored black, white and pink.

Advantages and disadvantages

The Irina tomato variety has the following advantages:

• early ripeness;
• bountiful harvest;
• high taste qualities;
• resistance to weather conditions - fruit sets at low temperatures;
• immunity to many diseases;
• good storage;
• transportability.

No deficiencies were identified . Among the specific features, one can note only the need for careful care.

What is remarkable about a hybrid: pros and cons

The advantages of this variety of tomato outweigh its disadvantages. Here are the main advantages inherent in this plant:

• abundant plant yield - per 1 sq. m can grow up to 20 kg of vegetables;
• early ripening;
• high level of resistance to diseases and pests characteristic of tomatoes;
• excellent tolerance to long-term storage and transportation;
• rich taste of the fruit;
• resistance to low temperatures;
• no need for pinching.

The negative characteristics of the variety mainly include agrotechnical difficulties, since this species is very demanding in terms of care and has its own characteristics of growth and development. Seeds removed from tomatoes cannot be used to grow new plants. Another significant disadvantage is the rapid deterioration in the quality of the fruit after it is damaged as a result of an impact.

Features of cultivation

Tomatoes Irina f1 can be grown in seedlings. The process begins in the second half of March.

Seeds are disinfected in a weak solution of potassium permanganate, placed in heated soil at a depth of about 2 cm. The distance between plants is approximately 2 cm. The soil for seedlings must also be disinfected and steamed. You can use growth stimulants, and plant the seedlings in special mini-greenhouses. Picking is carried out when the plants have 2 full leaves .

Watering is necessary without getting water on the leaves. After 50-60 days it is possible to plant it in a permanent place in a greenhouse, in open ground - a week later, the plants should have 6 leaves.

Before planting in the ground, you need to harden off the plants. Planted in a checkerboard pattern, the distance between plants is 50 cm. It requires the formation of a bush of 1 stem, pinching every one and a half weeks.

Loosening, mulching, fertilizing every 10 days. Watering at the root. Tying is required on individual supports in several sections of the stem.

The following are usually used as fertilizers for tomatoes:

• Organic.
• Mineral complexes.
• Yeast.
• Iodine.
• Hydrogen peroxide.
• Ammonia.
• Ash.
• Boric acid.

Recommendations for growing tomatoes

The agricultural technology of this variety is standard, but to get a good result, you will have to work hard.

Tomato productivity indicators depend on various conditions, including the type of seedlings. Strong and healthy seedlings take root much better in a permanent place, bear fruit abundantly, do not get sick and are pleasing to the gardener’s eye.

1. Seeds (if there is no information on the package) are disinfected in a solution of potassium permanganate, soaked in any growth stimulants, and then germinated.
2. Prepare a high-quality nutrient mixture for plants, boxes, pots, cups.
3. Determine the place indoors where the tomatoes will have to grow and gain strength before being planted in the beds or in the greenhouse.

Sowing for seedlings - mid or late March; at earlier times, the seedlings of this tomato stretch out and outgrow.

ON A NOTE! The best age of seedlings when planting is 55-60 days.

First, sow the seeds in common boxes or containers, then plant them in separate containers. The soil must be balanced in all components, loose, nutritious, and moisture-permeable.

Fertilizing seedlings – 2 times (you don’t have to do this if you know that the soil mixture contains enough nutrition for the plants). Watering is moderate, as the earthen coma dries out.

The plant is picked at the stage of two true leaves; after the procedure, it is necessary to shade the seedlings for 1-2 days from the sun. Planting time in open ground is at the end of May or beginning of June, in greenhouses - May. The exact timing is determined based on the weather conditions of the area, as well as the place of cultivation - in greenhouses or in the garden.

Diseases and pests

As already mentioned, the variety is resistant to many tomato diseases. However, information about the main greenhouse diseases and how to combat them may be useful to you. From the articles on our website you will learn which varieties do not suffer from late blight, how to protect plants from this disease, and what verticillium wilt is.

When grown in open ground, plants can be threatened by a variety of pests: Colorado potato beetle, spider mites, slugs, aphids. Microbiological preparations or insecticides will help in the fight against them.

Tomato Irina f1 is a high-yielding hybrid that will bring only the joy of growing to gardeners.

Further care

By providing the Irina F1 plant with proper care, gardeners can achieve amazing results.

Watering and fertilizing

Tomatoes should be watered exclusively at the root of the plant to avoid unnecessary wetting of the foliage. The liquid should not have a too low temperature; it is best to let it brew under the sun's rays. After 10-15 minutes of soil moistening, the area under the bushes needs to be slightly loosened. This will help prevent water stagnation.

At the stage of fruit formation, the plant must be fed with phosphorus fertilizers.

Loosening and removing weeds

Loosening, mulching and removing weeds must be carried out every 10 days. This is an important condition for the full formation of a tomato.

Bush formation

Although the plant of this variety has fairly strong trunks and is not very tall, experienced farmers strongly recommend gartering the crop with separate shrubs. They explain this by the fact that the Irina F1 tomato grows extremely heavy bunches that can cause significant damage to the stems.

Hybrid plants that have 2 or 3 branches give a bountiful harvest. This variety is best formed from 1 or 2 trunks.

Diseases and pests: preventive measures

With proper care, this variety of tomato remains absolutely resistant to all kinds of diseases. Breeders have done everything to develop a variety that can tolerate any disease. The gardener is only required to care for and water the plant on time, and in this case even late blight will bypass the tomato bushes.
