Tomato Main caliber f1: description and characteristics of the variety with photos

Tomato Main caliber F1 is a large fruit with very tasty and tender pulp. They have a sugary consistency and can be broken by hand without using a knife. This salad hybrid is appreciated by many tomato lovers.

Description of the tomato variety Main caliber f1 and its characteristics

There are several reasons why gardeners should turn their attention to Main Caliber tomatoes. These plants are immediately noticeable in any garden beds due to the large size of the ripening fruits. Main Caliber f1 is a tomato that belongs to extra-large hybrids, which breeders do not breed very often. Therefore, such varieties can be counted on one hand, and their high yield and excellent qualities of ripe tomatoes are the main positive qualities of such hybrids.

Description and characteristics of the hybrid

Description of the Main Caliber f1 tomato should begin with the fact that this variety belongs to the determinant type. The hybrid was bred for cultivation in open ground, as well as in greenhouses or film shelters.

Determinate tomato bushes are usually limited in growth - on the central shoot in the upper part, instead of a tip with foliage, an ovary with buds is formed, and the shoot does not grow further. Subsequently, one can expect further development of the plant from the lateral stepsons in the lower leaf axils. To obtain a full harvest, bushes of such tomatoes are formed into 2-3 trunks. Typically, breeders create determinate hybrids specifically for growing in greenhouses, since their height does not exceed 1.5 m, and the bushes are quite compact, which allows more tomato bushes to be planted in protected ground.

But not all types of determinate tomatoes are short; there are varieties whose height exceeds 1.5-1.6 m

The characteristics of this tomato are strong, powerful bushes of medium height (about 1.5 m). The shoots are strong, well leafy, the foliage is of medium size, typically tomato, dark green in color.

Usually, after the first or second true leaf, an ovary is formed. Up to 5-6 inflorescences can form on one shoot. This hybrid requires formation into one stem. But if the plant is grown in a greenhouse, or in warm areas in open ground, in order to obtain harvests throughout the season, you can leave lateral shoots after harvesting the first ripe tomatoes. New ovaries will form on them in the future.

The ripe fruits of the Main Caliber are round in shape, fleshy, the pulp is sugary, fine-grained. The skin is smooth and quite dense. The color of ripe tomatoes is deep crimson. Although some summer residents note that the color of the ripe fruits of this tomato can be bright scarlet. You don’t even need to cut ripe tomatoes – they break easily with your hands.

A ripe tomato can reach a weight of 0.5 to 1.5-2.0 kg. With timely fertilizing, you can harvest fruits weighing more than 2 kg. The yield of the variety is quite high - up to 5-7 kg per bush; in greenhouse conditions, higher yields can be harvested.

Main Caliber is intended for fresh consumption. The fruits can also be used to prepare tomato puree and tomato juice.

Advantages and disadvantages of the variety

The advantages of the variety include:

• high productivity;
• large size tomatoes;
• the harvested crop can be transported over fairly long distances;
• the hybrid is quite resistant to most diseases, especially late blight.

Tomato has practically no disadvantages, but the central shoot requires mandatory tying to supports, and the formation of a bush is also necessary. After planting the seedlings in a permanent place, regular watering should be provided, as well as fertilizing in sufficient quantities to obtain larger fruits.

How to grow large tomatoes?

Sowing of seedlings is carried out 80-90 days before the expected date of planting in the ground. There is no need to germinate the seeds before sowing; just soak them in a warm pink solution of potassium permanganate for 30-40 minutes, and then dry them until they become free-flowing.

Before sowing, the soil must be disinfected and watered well. Spread the seeds over the soil surface and cover with a layer of dry soil (0.5 cm). Cover the box with the seeds with film, leaving holes for air circulation. Place the container in a warm place (+25°C) and leave it alone for 4-5 days. After the first shoots appear, remove the film.

The seedlings should be watered as needed, and when 2-3 true leaves appear on them, plant them in separate pots with a diameter of 7 cm. After this, the seedlings only need to be watered on time, without drying out the soil. The optimal soil temperature ranges from +16... +25°C.

The soil for growing large tomatoes is prepared in the fall: the beds need to be filled with organic fertilizers (humus), complex mineral mixtures (Agricola, Kemira, Signor Tomato and others) must be added. Be sure to add a little dolomite flour, ground chalk or eggshells to the soil (1 kg per 1 m²). With a lack of calcium, large-fruited tomatoes can be affected by blossom end rot.

There are several reasons why gardeners should turn their attention to Main Caliber tomatoes. These plants are immediately noticeable in any garden beds due to the large size of the ripening fruits. Main Caliber f1 is a tomato that belongs to extra-large hybrids, which breeders do not breed very often. Therefore, such varieties can be counted on one hand, and their high yield and excellent qualities of ripe tomatoes are the main positive qualities of such hybrids.

Proven tomato varieties: practical large-fruited ones

Main characteristics of tomatoes for the garden

When choosing tomatoes for growing outdoors, you need to consider a number of factors. In the middle zone, and even more so in the northern regions, tomatoes that will be maximally adapted to such conditions are suitable for planting on ridges.

This means they must be:

• cold-resistant;
• early ripening;
• resistant to various diseases and pests.

The taste and size of the fruit are of no small importance.

The favorites will be low-growing, early-ripening varieties that form compact bushes that do not require pinching. They are easier to care for (you just need to install small support pegs), and the variety of types will allow you to choose the right size and color of tomatoes. Among modern “short” tomatoes there are very productive determinate varieties of tomatoes, large-fruited ones, and popular cherry tomatoes.

Indeterminate tomatoes in open ground are recommended to be grown in the south, as they have unlimited growth and medium-late or late ripening. Although today early indets have been bred, from which, in the short summer season, a good harvest can be harvested.

How to grow tomatoes

At the end of May - beginning of June, the seedlings are planted in a permanent place. By this time, the plants will be about 50–60 days old and each will have 5–6 true leaves.

Landing

Particular attention is paid to the place for planting tomatoes and the soil. The site chosen for this is sunny, without drafts. The soil is pre-fertilized and disinfected

For 1 sq. m plant no more than 2 bushes

The soil is pre-fertilized and disinfected. For 1 sq. m plant no more than 2 bushes.

Add 1 tsp to the wells. ash to fertilize the soil and eliminate possible acidic conditions. The seedlings are placed in the holes, moistened and sprinkled with soil.

For the first 10–14 days, the tomatoes are covered with a protective film. This will protect young plants from possible sudden changes in temperature and allow them to quickly adapt to new conditions.

Care

The Vzryv tomato variety is undemanding in terms of care, but it is necessary to follow the basic rules of agricultural technology.

Tomatoes are watered 1-2 times a week in the morning or evening when the sun is not shining. To do this, use rain or settled warm water. The best way to moisten the soil is the drip irrigation method. Tomatoes are watered regularly, but in moderation. Excess moisture leads to fungal diseases.

After each moistening of the soil, the soil around the bushes is loosened. This enriches the root system with oxygen. The ground is also weeded to remove weeds, which take nutrients from the tomatoes. Loosening is done carefully so as not to damage the root system. The soil around the plants is mulched with straw or weeds so that moisture is retained in the ground longer.

To obtain a bountiful harvest, the crop is provided with fertilizing 2-3 times during the growing season. To do this, use complex fertilizers, which contain all the microelements necessary for tomatoes.

Experienced vegetable growers note that the Vzryv variety is undemanding when it comes to fertilizers and feeds the crop with regular compost (2-3 times during the entire growing season). But still, for higher yields, some summer residents use special preparations for tomatoes, for example, “Sodium Humate” or “Diammofoska”.

Extra shoots take away most of the nutrients from tomatoes, which reduces the yield and quality of the fruit. Therefore, to obtain a rich harvest, the plants are pinched, that is, all lateral branches and excess leaves are removed. The bush is formed into 1-2 stems.

The first pinching is carried out at the stage of active development of the crop, the next – every 7–10 days. Stepchildren are not allowed to appear during the formation of ovaries and fruits.

Features of cultivation and possible difficulties

Since the variety has good resistance to harsh conditions, Explosion tomatoes are grown even in northern regions, but under covering material or in greenhouses.

The fruits will grow even without regular watering, but good care is a guarantee of stable fruiting. The variety is cultivated in two ways: seedlings or direct sowing in the ground. The first option gives an earlier harvest.

Diseases and pests

The tomato variety Explosion has strong immunity to characteristic diseases. If improperly cared for, there is a risk of plant disease from late blight, gray or white root rot. These diseases are treated with folk remedies, for example, hydrogen peroxide, brilliant green, potassium permanganate solution or copper sulfate.

Biological or chemical agents are also used:

• "Baktofit";
• "Barrier";
• "Barrier".

The drugs are used strictly according to the instructions indicated on the packaging.

The most common insect pests are slugs and Colorado potato beetles. They are fought with traditional methods, for example, with garlic infusion: add 200 g of grated garlic or onion to 10 liters of water and let it brew for a day; soap is added to the product for stickiness. You can also get rid of insects using the drug “Prestige”.

Description of large-fruited tomato hybrid Main caliber F1 and recommendations for growing

For those who choose Main Caliber F1 tomato for sowing, the description of the hybrid variety may seem too fantastic. But rave reviews and photographs of gardeners who have tried to plant seeds from Gardens of Russia since 2015 confirm the merits of these tomatoes.

Characteristics and description of the variety

The bush belongs to the determinate type, but quickly grows green mass. The height of the main caliber tomato reaches 1.7-1.8 m, after which the plant independently tops up and stops growing. During the season, 5-6 inflorescences are formed on the bush.

The hybrid is mid-season, therefore, in Russian conditions, the ripening of the first harvest is possible only in late July-early August. When growing tomatoes in a greenhouse, you can get earlier fruits.

The yield of the Main caliber hybrid is about 10 kg per bush. This is achieved not by the special abundance of tomatoes on the bush, but by their unusually large size. 3-5 fruits are formed on a cluster, the average weight of each is 500-550 g, but individual tomatoes can be much larger.

Like all modern varieties and hybrids, Main Caliber is resistant to temperature fluctuations and adverse weather conditions. Tomatoes bear fruit well both in greenhouses and in open ground, even in Siberia and the Amur region. Main caliber tomatoes are also resistant to late blight.

To prevent the appearance of fungus on tomato plantations, it is recommended to form powerful bushes of 2-3 stems with a mandatory garter to the trellis, and cut the lower leaves to 1/3 of the height of the plant.

Description of fruits

Tomatoes The main caliber F1 is a variety with the characteristic features of beef tomatoes. Huge rounded-flattened fruits with slight ribbing at the stalk have a fleshy structure and almost do not form seeds. The tomatoes on the bunch are approximately the same size; there are almost no small fruits.

Tomato Main caliber F1 is a hybrid, as the name suggests. This means that in your garden you can get a full harvest only from seeds from the manufacturer. And this is a guarantee of the characteristics it claims.

This tomato belongs to the determinate type. That is, plant growth is limited. But this is a huge, powerful, well-leafed bush - otherwise how can you get a good harvest? The height of the plant can be about 1.5 meters.

When growing, it is better to form a bush with 1 - 2 stems to avoid thickening. The tomato is considered resistant to late blight, but it is better to remove some of the lower leaves when the fruit begins to ripen. During the season, the plant forms 5–6 inflorescences, on which 3–5 fruits are formed. The average yield is 10–13 kg per bush. The stable weight of one tomato is from 500 grams. With good care, the weight of individual specimens will be more than 2 kg.

The plant needs and responds well to rich soil and fertilizing. The bush must be tied to a homemade support. And in order to avoid branches breaking off under the weight of the fruits, they may also have to be tied up.

Description of fruits

Tomatoes do not crack when ripe, have good shelf life and retain the juiciness and taste of the ripened fruit for quite a long time. Preservation is ensured by a strong skin, but it is thin and does not impair the taste. The fruits have a traditional aroma and a pronounced sweet and sour taste. The color of ripe fruits is crimson-red.

When grown in open ground, the stalk may retain a greenish tint. Ripening time is 100 – 110 days. This is a mid-season tomato; in mid-season conditions, the harvest can be expected by the end of July - beginning of August. When using shelters and growing in a greenhouse, the harvest can be obtained earlier. And for regions with a cool climate, it is recommended to use shelters at least at the initial stage of tomato cultivation - for a more complete yield of the crop.

The tomato is recommended for fresh use and making paste, as a preparation for juices and sauces.

Tomato Main caliber F1 is resistant to changes in air temperature and adverse weather conditions. It has proven itself well in indoor and open ground, and also confirms the characteristics described above when grown throughout Russia, including Siberia and the Amur region.

Diseases and pests of ampelous tomatoes

Manifestations of late blight

Ampel varieties of tomatoes, just like regular types, are susceptible to various diseases (fungal and viral), as well as pest invasions. The main cause of fungal diseases is excessive humidity when growing plants.

Next, the most characteristic diseases and pests of hanging tomatoes will be considered.

Blackleg

Seedlings affected by blackleg

Symptoms of the disease are the appearance of rot on the roots of young seedlings. The reason is too much moisture in the plantings. There is no treatment; affected plants should be removed along with a clod of earth.

For preventive purposes, it is recommended to treat the soil with Trichoderma before planting seeds, as well as moderate watering.

Late blight

Late blight of ampelous tomatoes

The cause of the disease is late blight - fungi from the class Oomycetes. It manifests itself in the appearance of dark areas on the leaves or fruits of tomato bushes. The disease can attack plants at any time of the year - both at the seedling stage and during harvest.

There is no treatment. To avoid spreading the disease to neighboring crops, the diseased plant should be completely dug up and destroyed (burned).

If the disease affects the crop in a state close to technical ripeness, you should cut off the entire bunch of tomatoes and place it in hot water for 1 minute, and then send it for ripening.

Gray rot

Early stage of gray rot

Mostly appears in the second half of summer. It affects the stems, leaves and fruits of the plant.

Plaque on the stems can exist for a long time without overly inhibiting the vital functions of the plant. But if the fruits are damaged, they quickly become unusable.

There is no treatment; affected plants are destroyed along with the harvest. A good way to prevent the disease is to periodically treat plants with Bordeaux mixture or sulfur preparations.

Mosaic of tomatoes

Damage to leaves by tobacco mosaic

A viral disease that first affects the foliage, then the stems and fruits. The causative agent is the tobacco mosaic virus, which attacks almost all Solanaceae. Initially, the disease manifests itself in the form of the appearance of individual yellow areas, then curling and deformation of the leaves is observed in the affected areas.

There is no treatment, but if the affected areas are removed from the plant at an early stage, its death can be avoided. The source of the disease can be anything: the virus can be carried by insects (very often this is done by aphids or ants), it can get onto plants from contaminated equipment, etc.

Recently, many seed producers have begun to carry out antiviral treatment. It is advisable to purchase just such planting material.

Insect infestation

The Colorado potato beetle is the main pest of nightshade crops.

Of all the pests, hanging tomatoes are most often affected by the following types of insects:

• spider mite;
• Colorado potato beetle;
• whitefly;
• aphids.

Depending on the type of insect, the appropriate insecticide is used. There are also universal products that have a wide range of applications: Aktara, Atkllik, Karbofos, etc.

Often, to repel insects, a container with garlic or another plant that has a characteristic odor is placed next to the container in which the tomatoes are located.

Characteristics of the Darenka tomato and agricultural technology for growing the plant

The Darenka tomato, with medium fruit ripening, is gaining popularity among gardeners due to its high yield and ease of plant care. Tomatoes are distinguished by their taste, have a dense peel, and retain their shape after pickling and canning.

Benefits of tomato

The Darenka tomato is a mid-season variety intended for cultivation in greenhouses and temporary shelters. During the growing season, a bush 1.2 m high is formed.

Description of fruits:

• Up to 6 red tomatoes ripen in a bunch.
• The fruits of the variety are calibrated, oval in shape, and resemble plums in appearance.
• The weight of the tomato reaches 150-200 g.
• The skin is dense, the flesh is fleshy, delicate in taste, with a distinct aroma.
• When cutting horizontally, chambers with a small number of seeds are observed.
• The yield per bush reaches 3.5 kg.
• In cooking, tomatoes are used fresh, for canning and pickling.

Agricultural cultivation technology

Depending on the growing conditions, sowing seeds for seedlings is carried out 50-60 days before transplanting to a permanent place. To speed up germination and improve plant health, seeds are dipped in an aqueous solution of potassium permanganate.

In order to improve fruit set, it is recommended to treat the seed with a growth stimulant before planting it in the ground. The seeds are placed in containers with soil to a depth of 1.5 cm, after watering with warm water using a sprayer, the container is covered with film until shoots appear.

The optimal temperature for seed pecking is 23-25 ​​°C. In the phase of formation of 2 true leaves, diving is carried out in separate containers with a soil mixture. For this purpose, it is better to use peat pots, in which they are planted in a permanent place.

When planting in the ground, 3-4 bushes are placed per 1 m². When grown, 2-3 stems are formed. To increase the yield, it is recommended to remove excess shoots. The bush requires tying to a support.

During the growing season, the plant is periodically watered and fertilized with complex mineral fertilizers. It is recommended to periodically loosen the soil to create a balance of moisture and air near the root system.

Opinions and recommendations of vegetable growers

Reviews from gardeners cultivating the Darenka variety indicate the excellent taste of the tomato and the universal use of the fruit.

Daria Emelyanova, 46 years old, St. Petersburg: “When choosing a tomato for growing in a greenhouse, my attention was attracted by the description of the Darenka variety. I planted the seeds for seedlings, after soaking them in aloe juice

To form a healthy plant, it was additionally treated with a growth stimulator. In the phase of 2 true leaves, she dived into pots.

During the growing season, the bushes reached a height of over 1 m. Clusters of tomatoes grew on the stems. At first the tomatoes were a rich green color, and then acquired a dark red color. The aroma is amazing, the flesh is fleshy and tender in taste. When canned, the tomato retains its shape and does not crumble into mush.”

Anatoly Andreev, 56 years old, Krasnodar: “Seeds of the Darenka variety were suggested by a neighbor in the country

The characteristics of the fruit and the ability to grow under film cover attracted attention. Sowing of seeds was carried out 2 months before transferring to a permanent place

Before placing them in a container with a soil mixture, the seeds were treated with special preparations to improve growth.

The seedlings were transferred in mid-May to prepared holes with compost. Additionally, complex mineral fertilizers were added. Before planting, I watered each hole so that the root system did not experience a moisture deficiency. I formed the bushes into 2 stems, so some fruits reached a weight of 300 g. The tomatoes have a rich taste, the flesh is fleshy, and there are few seeds in the fruits. When canned, tomatoes retain their shape due to their thick skin.”
