The most popular indeterminate varieties of tomatoes, growing features

All currently existing tomato varieties can be divided into determinate and indeterminate according to their growth type. The development of the former is limited to a certain number of hands, which depends on the characteristics varieties.

The latter have unlimited growth; they have a flower cluster every 3-4 leaves. From an economic point of view, indeterminate varieties are more profitable, since their yields are much higher.

The most popular varieties for open and closed ground

Of the most popular varieties of indents for open ground, the following should be noted:

• Ox heart
• Pink giant
• De Barao
• Lemon giant
• Steak

Among the many varieties for greenhouses, the following are particularly noteworthy:

• Marfa
• Mazarin

• Octopus
• Pink Paradise

Let's look at some of them in more detail.

Ox heart

A well-known and widespread large-fruited variety called indent. It is characterized by large, heart-shaped fruits of pink-crimson color. The average height of the bushes is 1-1.2 meters. The weight of the fruit is 300-400 g. The taste characteristics of tomatoes are high. Their main purpose is salad.From the moment of sowing to the harvesting of the fruits, about 105-110 days pass.

Pink giant

Large-fruited variety of medium ripening with high taste characteristics. It was included in the State Register of Varieties in 2000. Suitable for growing both in greenhouses and open ground.

The average height of the bushes is 1.5-1.7 meters. The pink giant is characterized by fairly high resistance to most diseases. When properly formed, the average yield is up to 3-4 kg of fruit from each plant. Fruit weight is from 500 to 900 g.

Mazarin

Large-fruited indent for closed ground. It is characterized by medium fruiting periods and high yields. The height of the bushes is about 1.5 meters. The shape of the fruit is heart-shaped, their weight ranges from 600 g to 1 kg. The color of ripe tomatoes is deep crimson. Their main purpose is to eat fresh. The variety requires mandatory shaping.

Octopus

The second name of this variety is “Tomato Tree”. It is characterized by enormous growth vigor, a large number of lateral shoots and a well-developed root system. The fruits are red in color with an average weight of 150-200 g. They have excellent keeping quality. When grown in a year-round heated greenhouse, it is capable of forming a bush of gigantic wasp sizes with an average crown area of ​​up to 50 m2.

Pink Paradise

Pink-fruited variety with very high taste characteristics. Designed for cultivation in closed ground conditions. The height of the bushes can reach 2 meters. It has the ability to increase shoot formation, therefore it requires mandatory shaping.

It has high yields; with good care, you can get up to 4 kg of fruit from each plant.Their main purpose is to eat fresh. They can also be used to make sauces and juices.

Features of development, advantages and disadvantages of indeterminate varieties

Among the developmental features of indeterminate tomatoes, it is worth noting their ability to grow unlimitedly. The ripening of their fruits can occur simultaneously with the laying of new flower clusters. The height of the main shoot of this group of tomatoes can be up to 2 meters or more.

Advantages:

1. High yields.
2. When grown in heated greenhouses, one bush can actively grow and bear fruit for several years.
3. An extended period of fruit formation and harvesting, which allows for a constant harvest.

Flaws:

1. Long period of development.
2. Later ripening dates.
3. In conditions open ground can only be grown in regions with a long summer period.

The indeterminate group of tomatoes is most often used for growing indoors. This allows for the most efficient use of the greenhouse area. With the correct selection of varieties, it is possible to grow indeterminate tomatoes in open ground conditions.

Formation and care

Among the mandatory measures for caring for indets, it is worth noting the shaping. Without this event, it will not be possible to get a high harvest. The basic principle of shaping is to remove excess side branches and stepsons. For most varieties, it is enough to leave 1 or 2 main trunks.

If this is not done, the excess green mass will take the bulk of the nutrients from the main stem.And this, in turn, will certainly affect the yield and ripening time. In addition, too dense green mass interferes with normal ventilation, which creates a favorable environment for the development of various fungal infections.

When growing indeterminate varieties in open ground in early August, be sure to pinch the central shoot. The main goal of this event is to accelerate the ripening process of the remaining fruits. Tall varieties of tomatoes should be grown with a mandatory garter.

For these purposes, the greenhouse is equipped with trellis. Depending on its design features, its base can be a wooden or metal frame. It is best to use twine as a garter material.

To increase the feeding area of ​​tall tomatoes, it is recommended to use special techniques aimed at forming an additional root system. For example, once every ten days after watering, you can hill up the stems with a small amount of a mixture of soil and humus.

After the height of the plants reaches 30 cm at a height of 15 cm from the soil on the stem, a small section of the skin is removed using a knife. Then the plants located nearby are combined with each other and secured with insulating tape. After 10-12 days, the stems will grow together at the junction.

After this, the least developed plant is cut off just above the cut point. Due to this technique, the feeding area of ​​the remaining bush is significantly increased. Also, when growing indeterminate tomatoes in a greenhouse, be sure to remove the lower leaves.

The signal for the start of this event is the death of the leaf plates located at the very bottom. Also when cultivating tomatoes in the greenhouse, one should not forget about preventive treatments with copper-containing preparations. This will help prevent the spread of various fungal infections characteristic of greenhouse conditions.

During the growing season, do not forget about periodic feeding of plants. To do this, you can use both organic matter in the form of fermented mullein infusions or bird droppings, and mineral fertilizers. It should be taken into account that at the beginning of development, plants most of all need nitrogen, and during the period of budding and fruit filling in the phosphorus-potassium complex.
