One of the best varieties for industrial cultivation is Extra F1 cabbage: reviews and description

Cabbage is a vegetable that is in demand in the kitchen all year round. But only late varieties are suitable for storing in the cellar. One of these is the Extra F1 hybrid, a description of which, obvious advantages over other varieties, basic agricultural technology and reviews are in the article.

Description of the variety

Extra F1 cabbage was created by Russian breeders in the late 90s. At the same time, the main goal of the specialists was to obtain dense heads of cabbage that were resistant to deformation during mechanical assembly. Description of the variety:

• the rosette is slightly elevated above the ground;
• diameter of an adult plant is 50 cm;
• the leaves are medium-sized, the plates are smooth, the edges are wavy; the presence of a matte coating;
• the heads are flat-rounded with a smooth base; when cut, the fruits are white-yellow;
• gastronomic properties are high;
• versatility in cooking: the hybrid can be eaten raw, made into preparations and various dishes.

Description and characteristics of the variety

The hybrid was bred in Moscow in 1995, the year of inclusion in the register was 1997. Extra F1 cabbage is recommended for cultivation in the regions:

• Northwestern;
• Central;
• Volgo-Vyatsky
• Central Black Earth
• North Caucasian
• Middle Volga and Lower Volga.

In addition, it is successfully grown in Western Siberia and the Far East.

Cabbage is recommended for long-term storage, fresh consumption and pickling. The hybrid ripens late - on the 160th day after emergence. During the growing season, it forms a semi-raised rosette no more than 35 cm high and 55 cm in diameter. The leaves are medium-sized, obovate, on short petioles with dark green plates covered with a strong waxy coating. The edges are slightly wavy. The stem reaches a length of 15 cm.

The height of the head is 17 cm. It is extremely dense, smooth, green on the outside, with a slight purple color, and white-yellow when cut. The stalk is about 5 cm long. The stalk reaches 2.5-2.8 kg.

All heads of cabbage are aligned and of the same type. The taste is good.

Advantages and disadvantages

Due to a large number of characteristics, the white cabbage variety has clear advantages in comparison with other species.

Main advantages:

1. The variety has high immunity to many crop diseases.
2. Heads of cabbage do not become deformed due to untimely care, during mechanical harvesting and during storage.
3. Long-term storage allows the vegetable to be used throughout the cold period.
4. This variety is ideal for winter harvesting.

Summer residents consider one of the disadvantages to be demanding of light. Even slight shading reduces fertility significantly. The inability to obtain high-quality fruits and seeds from a hybrid is also a negative side of the variety.

Advantages and disadvantages

Thanks to the mass of positive characteristics, the presented white cabbage variety has clear advantages over other varieties.

The main advantages of the hybrid:

1. Cabbage is endowed with lasting immunity to most crop diseases.
2. Heads of cabbage do not crack due to deviations in care, during mechanical harvesting and during storage.
3. Long shelf life allows you to use the vegetable throughout the upcoming cold period.
4. The described cabbage is an ideal option for preparing for the winter.

Gardeners consider one of the disadvantages to be demanding lighting. Even slight shading reduces the yield several times. The inability to obtain high-quality fruits and, accordingly, seeds from the hybrid form is also considered a negative side of the variety.

Features of cultivation

The ideal option for agricultural technology is through seedlings. To obtain high-quality seed, greenhouses are used.

Seeds should be planted in mid-March. If delayed, the cabbage will not have time to ripen. Ready seedlings are planted in open areas. Cultivating a hybrid under cover is irrational. After 20 days, the cabbage is fully formed, after which it is used for feeding.

Organic and mineral complexes are used. Harvesting is carried out only after the heads of cabbage are fully formed. At this time, the cabbage completely stops growing and becomes dense.

About

Features of agricultural technology

The best way to cultivate cabbage is through seedlings. To obtain high-quality planting material, greenhouses are used.

Attention! The latest time for sowing seeds of this variety is mid-March. If work is delayed, the cabbage will not have time to ripen.

The finished seedlings are transferred to open ground. Growing a hybrid under cover is unprofitable. After 20 days, the cabbage takes root thoroughly, after which they begin fertilizing. Organics and mineral complexes are used. Harvesting is carried out only after the heads of cabbage have fully ripened. During this period, the cabbage completely stops growing and becomes stiff.

Caring for cabbage in the ground

You don’t need any special knowledge to grow Extra cabbage. If you have chosen the right area without wind and there is lighting, then a positive result is guaranteed. The variety does not like other crops living next to it. Groundwater negatively affects the ripening of the leaf component.

Therefore, if you cannot find another place, then the bed must be raised, more drainage layer and fertile soil must be added. In the future, you need to irrigate, loosen the soil or mulch when the bushes are 15 cm high, and feed them.

Every 8 weeks it is necessary to feed the soil. The main thing is not to overdo it, otherwise the leaves will begin to rot. You can also add an infusion of mullein, chicken droppings, and wood ash.

Characteristic

The hybrid is a late-ripening vegetable. The period from germination to full ripening of the crop lasts about 154-170 days. Productivity is at an average level. From 1 m2 you can collect up to 4.2 kg of marketable products.

Representatives of Extra F1 have a semi-raised rosette, up to 34 cm high and about 55 cm in diameter. The leaf blade is small, obovate in shape. The petiole is very short. The surface of the leaf is smooth, there is wavy along the edges, but it is very weakly expressed. Leaf color is dark green. There is also a strong wax coating on the surface. The outer stump is quite long and can grow up to 15 cm.

The heads of cabbage are formed smooth, flat-rounded in shape. Head height up to 18 cm. The structure is very good, dense. Thanks to this, there are no problems when transporting the “heads” or collecting them mechanically.

The outside of the head of cabbage is colored green, the inside of the cabbage is white and yellow. The inner stump is about 6 cm long. The weight of a technically mature vegetable reaches 3 kg, although on average it is in the range of 2.2-2.8 kg.

Diseases and pests

Diseases that can affect vegetables:

1. Kila. To get rid of it, you need to use formalin and burn the diseased inflorescences.
2. White rot. To prevent the disease from making itself felt, it is necessary to use fertilizing. It is important to follow the rules of crop rotation.
3. Blackleg. The product Fitosporin is used, which acts quickly to eliminate the fungus.
4. Gray rot. This problem occurs when storing vegetables. The room must be ventilated, and the walls must be treated with bleach.

Among the pests you need to watch out for:

1. White fly, cutworm, cabbage fly. The soil should be sprinkled with a mixture of naphthalene and sand as a preventive measure. If insects suddenly appear, it is necessary to treat with a dust mixture.
2. Cruciferous flea beetle. You can remove it with ground pepper or tobacco smoke.
3. Aphid. To get rid of it, special means or an infusion of tobacco smoke are used.

Growing seedlings

To sow seeds, prepare loose soil from 5 parts peat and 1 teaspoon sand. Ash and 200 g/kg of soil must be added to it. The soil mixture is left in a warm room.

It should warm up to 25 C. Some gardeners heat the soil in the oven at a temperature of 50 C as disinfection.

Before sowing, seeds are washed and disinfected in a 1% solution of hydrogen peroxide. Processing is continued for 30 minutes. Then they are placed in a damp cloth and left to mature.

During the day they are at room temperature, at night they are placed in the refrigerator. This temperature difference has a good effect on the core. Metabolic processes begin in it.

To shorten the growing time of seedlings, it is recommended to sow in individual containers. This will allow you to avoid the process of diving, which damages the root system of plants.

When sowing, the seeds are deepened by 1 cm and covered with film until widespread germination. When growing seedlings, it is necessary to maintain 3 different temperature conditions:

1. seeds ripen at a temperature of 25 C.
2. when sprouts begin to appear en masse, they maintain a daytime temperature of 12-15 C, a night temperature of 8 C.
3. Before planting in the ground, seedlings are adapted to the air temperature outside the room. They begin to take her out to the garden plot. The seedlings are first left for 1 hour. Then, the hardening time is gradually increased to a day.

Before planting seedlings in open ground, it is recommended to soak the roots in the Siyanie-1 solution, in a liquid mixture of ash and clay, or in the Immunocytophyte preparation. This is a prevention against fungal diseases, such as cabbage clubroot, which can affect plants.

Advantages and disadvantages of cabbage

Extra F1 has a number of advantages, among which it is primarily worth noting:

1. Long shelf life of the crop.
2. Cabbage is not damaged by mechanical harvesting.
3. It has protection against diseases such as gray rot, fusarium wilt and various manifestations of bacteriosis.
4. Suitable for both fresh consumption and processing (in particular fermentation).
5. Inside the head of cabbage there is a relatively small stump.

There are no shortcomings as such. The only small negative is the large external stump. Because of this, it will be necessary to carry out 2 hillings per season. Otherwise, the cabbage may tip over on its side when the “head” is fully ripened. Also, many gardeners note that the leaves of the hybrid are quite hard.

Reviews from gardeners

Vladimir Ivanovich, Voronezh, 43 years old.

I once planted this cabbage for personal use. For testing, so to speak. Of course, this cabbage has its pros and cons, but for me personally there are more cons. In order. I’ll say right away that cabbage lasts a very long time. It stayed with us until April. It may have been lying around longer, but the last head was eaten just in April. Also, the heads of cabbage are very dense, which is good. And now about the shortcomings. The taste, in my opinion, is not very good. All because of the toughness. The leaves are very hard. I also tried salting it, but I didn’t like it that way either. I don't grow any more.

Dmitry Igorevich, Kyiv, 39 years old.

I liked Extra f1. I grew a Stone Head before, but I didn’t like it at all, as if it were stone. Even hares will break their teeth on cabbage. But this hybrid is pretty good. It lasts a long time, not bland, juicy. The leaves are a little harsh, but tolerable, in any case, when compared with Stone Head, the difference is obvious.
