Features of planting and growing

The hybrid is grown by seedlings and sowing seeds in open ground. The key points of agricultural technology are compliance with the planting scheme and timing, timely watering and proper fertilizing.

Preparing for landing

For the crop, choose a flat, sunny area without shade. The earth has been dug up since autumn. Floodplain soils and chernozems - to a depth of 25–30 cm, peat bogs - up to 30–35 cm. In spring, the soil is loosened and humus is added (5–8 kg/m²).

The seeds of the SB 3 hybrid are calibrated and treated with a fungicide, so they are not additionally soaked or disinfected.

Preparing seedlings

For seedlings, take a neutral substrate or make a nutrient mixture yourself:

• turf soil - 1 part;
• humus - 1 part;
• peat - 1 part;
• wood ash - 1 tbsp. l. per 1 kg of mixture.

Prepare trays and plastic cassettes 4.5x4.5x3 cm. The most convenient container is peat cups. In them, seedlings are planted in the ground with minimal risk of plant deformation.

The trays are filled with a nutrient mixture to a depth of 5–10 cm. Furrows are made at a distance of 3 cm, deepened by 1 cm, and the soil is moistened. Seeds are planted at intervals of 2 cm, sprinkled with soil and lightly compacted. Plant 1 seed in separate containers.

Important! Seeds for seedlings are sown from late March to mid-April. Properly grown seedlings should be no higher than 25 cm and have 5-6 leaves.

Before germination, maintain a temperature of +15…+18°C. Afterwards, the seedlings are moved to a bright place with a temperature of +7...+10°C, gradually increasing it to +15°C. Water the plants moderately. Seedlings from trays sprout with the appearance of 2 true leaves. A week before planting in open ground, the temperature is reduced to +10°C.

Non-seedling planting

Seeds are sown in open ground at the beginning of May according to a pattern of 60–70×50 cm. Planting depth is 1.5–2 cm. From 3 to 5 seeds are placed in each hole.

They are covered with a mixture of earth, humus and peat in equal parts. The beds are watered and covered with film. With the appearance of the second true leaf, the film is removed and the seedlings dive.

Soil requirements and predecessors

Any soil with neutral or slightly alkaline acidity is suitable for cabbage. Loam will be the best.

Favorable predecessors:

• cereals;
• beet;
• cucumber;
• tomatoes;
• potato;
• legumes;
• pumpkin

Unfavorable:

• onion;
• carrot;
• peas;
• turnip;
• radish;
• all types of cruciferous vegetables.

In one area, cabbage is replanted after 5 years.

Landing rules

At the age of 45–50 days, the seedlings are transplanted into open ground. This usually happens in the second ten days of May, when the temperature has settled at +10°C.

Plants in peat cups are planted together with the container, from plastic trays - by transshipment. To prevent the earthen ball from disintegrating, water the seedlings 2 hours before planting. Plant according to the pattern 60–70×50 cm.

Work order:

1. The holes are prepared in the first half of the day. Depth - 15–20 cm, diameter 10 cm greater than the diameter of the root system.
2. Add a mixture of 1 tbsp to each well. humus, 1 tbsp. l. chalk and handfuls of wood ash. Sprinkle a little earth on top and moisten with 1 liter of water. The planting holes are left for 2-3 hours to allow the soil to settle.
3. To prevent bacteriosis, prepare a clay mash with a solution of “Fitolavina-300” (0.3-0.4%). The roots of the seedlings along with the soil are dipped into it.
4. Plants are planted deep to the cotyledon leaves. The holes are filled in so that the apical bud remains above the ground and watered. After an hour, sprinkle the wet soil with dry soil: this will slow down evaporation and prevent the formation of a crust.

Features of cultivation

In the southern regions and areas with a mild climate, cabbage is sown in open ground. For areas with cold climates, the seedling method is recommended. In very short summer conditions, seedlings are planted in greenhouses.

Nuances of care

The main emphasis in caring for the crop is to maintain moisture in the upper layers of the soil. A rational option would be drip irrigation.

An alternative method is mulching. Mulch prevents moisture evaporation, crust formation and weed growth. Dry straw, rotted sawdust, manure, and agrofibre are used for cabbage.

Watering

Young seedlings are watered at the root, once every 2-3 days, using 1 liter per plant.With the beginning of the formation of heads of cabbage, moisture is reduced to 1 time per week. Water consumption - 10–12 l/m². Stop watering the plantings 2 weeks before harvest.

Loosening and hilling

The soil is loosened for aeration and as a pest control measure.

Work order:

• after rooting, the seedlings are loosened to a depth of 4-5 cm;
• repeat after a week with a depth of 6–8 cm;
• further - after each watering, until the leaves close.

Hilling stimulates root growth. To do this, the soil is raked up to the plant down to the lower leaves. The procedure is performed 20 days after planting, once every 3 weeks, until the leaves close.

Attention! In rainy weather, waterlogged soil is removed from the stem to prevent rotting.

Top dressing

The hybrid is fed at the initial stage of setting heads and 2 weeks after. 10 g of urea, 30 g of superphosphate, 15 g of potassium chloride are diluted in 10 liters of water. For each plant use 0.5 liters of solution.

Measures to increase yield

Additional nutrition will help increase harvest by 30%. Before planting, add “Mag-Bor” to the soil (1 tbsp per 1 m²). During the season, 2-3 foliar feedings are carried out with a complex of microelements (for example, “Tsitovit”).

Diseases and pests

The causes of hybrid diseases are extreme heat (above +30°C), flooding of the area, contaminated soil, and insects.

Possible diseases and pests:

1. Mucous bacteriosis - mucus appears, the leaves rot and fall off, the head of cabbage softens. As a preventative measure, plants are dusted with wood ash. For treatment, the drugs Trichodermin and Planriz are used.
2. Vascular bacteriosis - growth slows down, the veins on the leaves darken, forming a network, the leaves turn yellow and dry, the heads of cabbage are deformed.For prevention, cabbage is sprayed with a solution of brilliant green (15 drops per bucket of water). Planriz and Trichodermin are used.
3. Powdery mildew - spots with a white coating appear on the leaves. Plants are sprayed with “Fitosporin” or a 1% solution of Bordeaux mixture.
4. Cabbage fly - larvae damage roots. Crops are treated with Thiophos. The soil is sprinkled with mothballs or tobacco dust.
5. Cabbage aphids and cruciferous flea beetles feed on leaf sap. The culture is sprayed with a tobacco-ash solution (200 g of ash and tobacco per bucket of water). Dill, garlic, and parsley are planted next to cabbage.

Harvest and storage

The harvest is harvested in September. The heads of cabbage are pulled out along with the stem and allowed to rest on the beds for 2-3 days so that the outer leaves wither. Then the stalks are cut off, leaving 2-3 cm; the outer leaves are not removed.

The cabbage is laid out on a wooden floor or in boxes with perforated walls. Store in a dark room at a temperature of -1...+5°C and air humidity of 90%. The shelf life of the crop is about 4 months.

Growing difficulties

The main problem when cultivating cabbage is that the heads of cabbage do not set. There are a lot of leaves, the plant looks healthy, but it stretches strongly upward and does not form a fork.

Possible reasons:

• late sowing dates;
• planting thickening;
• overdose of nitrogen fertilizers;
• overmoistening or insufficient watering.

To improve the situation, rosette leaves are collected into a bud and secured with a soft rubber band or rag tape. This encourages the cabbage to form forks.

For additional stimulation, plants are sprayed with a solution of boric acid (15 ml per 10 liters of water). Normalize watering, maintaining optimal soil moisture.

Tips and reviews from experienced gardeners

Most vegetable growers speak positively about SB 3 F1 cabbage, noting its high yield and excellent taste:

Lyudmila, Kotelnich: “We grow several types of cabbage and store it until January. The most unpretentious of them is the hybrid SB 3. For many years I have been using only this for fermentation.”

Svetlana, Kaluga: “I planted different varieties, read the descriptions - I chose cabbage SB-3... It grows without problems, I’m happy with the harvest, I’m mainly struggling with the cruciferous flea beetle. Anti-flea shampoo for animals helps very well (2 tablespoons per 10 liters of water). For prevention, I spray once a week.”

Conclusion

Cabbage SB 3 F1 is a mid-season hybrid for growing throughout Russia. It is cold-resistant; the heads of cabbage do not crack under any weather conditions. The crop is valued for its one-dimensionality of forks and high yield rates. Vegetable growers consider this cabbage one of the best for pickling.
