Subject to agrotechnical conditions, irrigation regime and timely feeding, the hybrid gives a high yield. Up to 8 kg of root crops are harvested from 1 m². Moreover, the weight of 1 fruit reaches 150-160 g.

In large farms, the average yield reaches 60-70 tons per hectare.

Disease resistance

There is an average resistance to blooming, shooting and cracking of root crops.

High immunity to common cultural diseases:

• downy mildew;
• cercosporosis;
• root rot;
• alternaria.

Description of appearance

Boltex F1 belongs to the biennial herbaceous plants of the Umbrella family, a subspecies of the wild carrot sowing table. A hybrid variety of the Shantane variety.

Rosette tops are spreading, powerful, erect. Leaves are medium, dissected, bright green in color.

The root crop is elongated, conical, with a blunt rounded tip. It grows in length up to 15 cm. The circumference at the base is up to 4-5 cm. The fruit is dark orange in color with a juicy, homogeneous, dense pulp. The core is medium in size, not pronounced. The rind is thin, even and smooth. Due to the high content of sugar, beta-carotene, solids, the taste is delicate, sweetish, without bitterness.

The presentation and taste are preserved for 10-12 months.

For which regions is it suitable

The culture is cold-tolerant and, with sufficient watering, tolerates summer heat well. The hybrid is adapted to heavy types of substrate.

Root crops have time to fully mature in climatic zones with short summers and frosty winters.

Boltex hybrid is sown in Siberia, in the Urals. It is also zoned in the northern, southern, temperate latitudes of the country.

Advantages and disadvantages

The virtues of culture:

• equally high yield in open ground and greenhouses;
• copes well with daily temperature fluctuations;
• seedlings germinate even with spring frosts down to –4 ° С;
• in a cool summer, root crops fully develop.

Among the disadvantages, farmers note:

• seed material is not cheap;
• hybrids do not produce high-quality seed "offspring";
• in the second generation, morphological characteristics are lost, positive properties are disintegrated into the forms of predecessor-parents.

Difference from other varieties and hybrids

Boltex F1, according to the magazine "Seed Supermarket" (No. 5, spring 2016), is recognized as the best variety for storage.

The pulp is homogeneous, the core also has an orange tint.

The improved subspecies is intended for sub-winter planting, root crops have time to ripen before the onset of cold weather.

Features of planting and growing

When landing hybrid Boltex F1 it is important to take into account agronomic conditions, features of soil preparation, seed material and the method of cultivation.

Preparing for landing

In April - early May, the site is prepared:

• dug up the beds;
• break large clods, level the substrate with a rake;
• weeds are removed by the root;
• during autumn digging, the beds are fertilized with compost, droppings, and minerals.

It is important to treat the seeds with special growth preparations before planting. Stress adaptogens provide fast adaptation and 100% germination. Seed material is soaked for 2-3 hours in a growth stimulator "Kornevin", "Epin", "Energen Aqua".

Ground requirements

The variety is suitable for all types of soil, including heavy chernozem, sandy loam and loamy soils. An important condition is a fertile layer of at least 20-25 cm.

Important! To reduce the acidity of the soil, the Boltex liming method is not recommended for carrots. Use soft soil deoxidizers - dolomite flour or wood ash.

To improve moisture permeability and looseness, coarse river sand is added to heavy stony soil or loam.

Predecessors

Boltex carrots grow well after garden crops:

• tomatoes;
• cabbage;
• Luke;
• garlic;
• bitter and sweet pepper;
• early varieties of potatoes;
• cucumbers.

The culture grows and develops poorly after:

• greens (cilantro, parsley, dill);
• celery;
• beets;
• cumin.

Timing, scheme and landing rules

Sow treated in advance seed in open ground or a greenhouse in the first decade of March (early spring sowing). Summer plantings (for storing crops for the winter) are carried out at the very end of May or early June.

Important! Late spring (subwinter) crops give a full harvest, root crops are stored throughout the winter, do not dry out, do not shrink, retain their nutritional composition and taste.

The landing is carried out according to the scheme:

• consumption rates are calculated in the ratio of 0.2 g per 1 m², respectively, 2 g (one package of seeds) is enough for a plot of 10 m²;
• row spacing - at least 15-20 cm;
• the distance between seedlings is 3-4 cm;
• the seeds are buried by 1-2 cm;
• for uniform distribution of seeds, sowing is carried out manually;
• the optimum temperature for sowing is 10-12 ° C;
• in cold regions, seeds germinate at a temperature of + 5 ... + 6 ° С;
• full-fledged root crops are formed and ripen at a temperature of + 20 ... + 23 ° С.

Growing features

In dry, infertile soil, seeds germinate poorly, seedlings are weak, often get sick and die.

It is important to comply with the burial norms. When planted deeply, the sprouts do not receive adequate nutrition. With superficial planting (without sufficient deepening), the germination rate decreases due to the drying out of the upper layer of the substrate. Sprouts grow variegated, 7-10 days late.

The culture prefers lighted planting sites, tolerates summer heat well. Podzimny sowing is carried out in late October or early November, mainly in closed ground, with temperature control and backlighting.

To maintain moisture exchange and soil moisture in the summer heat, the beds are mulched with sawdust or hay. In cold regions, immediately after sowing, it is recommended to cover the area with foil overnight. During the day, the shelter is periodically removed for 1-2 hours for airing.

Watering mode

Abundant daily watering is recommended at the beginning of the growing season and during the formation of root crops. The optimal mode is regular, as the top layer dries. In moderate climatic conditions, watering once a week is sufficient. At the end of the formation of root crops, watering is halved, taking into account precipitation and temperature. Excessive moisture will cause cracking and warping. The moisture content of the substrate 2 weeks before harvesting should not exceed 60%.

Thinning and weed control

Weeding is carried out regularly, as it becomes clogged... They are loosened a week after the germination of seeds (to a depth of no more than 7 cm), then - with an interval of 14-15 days. When the seedlings have 1-2 true leaves, the crops thin out, leaving a distance of up to 4 cm.

In order not to harm the roots, before weeding and thinning the seedlings, the soil is moistened, after weeding the rows are mulched.

Top dressing

Organic fertilizers are introduced in advance during the autumn digging of the site. For these purposes, compost, diluted manure or droppings are suitable.

Mineral complexes (potassium, phosphorus) are introduced throughout the entire period of growth and formation of root crops. The recommended dose of fertilizers is up to 15 g per 1 m².

For systemic feeding, fertilizers "Kemira", "Nitrofoska" are used. In the northern regions - calcium sulfate at the beginning of the growing season.

Disease and pest control

Overflows are unacceptable - root crops become infected with root rot, the crop rots.

It is advisable to treat the seedlings and the substrate with pesticides ("Fitoverm" is sprayed on the tops). The last treatment is 3-4 days before harvest.

Important! Mulching the beds saves you from garden pests.

Organic matter (compost and manure), a layer of mulch (peat, sawdust) must be disinfected with urea.

Powdery mildew, carrot flies, spotting are treated with a solution of Bordeaux liquid or other fungicides and insecticides (antifungal drugs "Intavir", "Actellik").

Harvesting and storage

The harvest on time is the key to good keeping quality and long storage... Overexposing root vegetables is not recommended.

How and when to collect

Harvested in 3-3.5 months from the day of sowing.

Harvesting rules:

• stop feeding at least 3-4 days;
• complete watering in a week;
• dig it out only in dry weather with a shovel;
• cut off the tops with a sharp knife.

Storage features and keeping quality

The harvest is stored in special rooms (cellar, basement, shed). The optimum temperature is -2 ° C. Permissible air humidity - no more than 95%.

Important! When storing, exclude exposure to sunlight and moisture.

Storage method:

• in stacks;
• in bulk;
• in the pyramids;
• boxes;
• plastic bags;
• trenches and pits.

Immediately after harvesting, the roots are sorted, damaged by diseases are removed. Dry for an hour. Refrigerate in a darkened room for 7 days.

Damaged roots are cleaned, grated, processed, or sent to the freezer. Such a crop cannot be stored.

Growing difficulties

The peculiarity of the variety is that the seedlings make their way slowly. Due to abundant spring rainfall and watering, the soil hardens, which complicates the germination and development of seedlings. It is important to avoid soil crust formation. Timely weeding and surface loosening of the substrate is recommended.

The beds are weeded regularly, at least 3-4 times per season. After watering, it is important to huddle - the bare roots turn green from the sun.

Tips from experienced gardeners

If the site has not been fertilized in the fall, in the spring, after digging the beds, dolomite flour is scattered directly over the surface of the soil. Observe the proportions - 2 tbsp. for 1 m². Then the fertilizer is carefully covered with a rake to the length of the teeth - 6-7 cm. It is at this depth that beneficial soil microorganisms and bacteria live.

It is important to spill furrows with warm water before burying the seeds. This procedure ensures fast germination and activates growth processes.

Boltex hybrid does not tolerate shading, especially at the beginning of the growing season. The seedlings are stretched, the roots are crooked and small.

Agrotechnical trick. When grown on ridges and ridges, the amount of the crop increases by 1.5-2 times.

Reviews of the Boltex carrot hybrid

According to statistics from agricultural stores and supermarkets, Boltex carrots received 94% of positive responses. On the forums, summer residents give a positive assessment to the hybrid.

Vladimir D., Moscow region: “I recommend Boltex to everyone. An excellent carrot grows. The seeds, however, are expensive, but of high quality, everything pays off. Sweet and juicy until spring, I keep it downstairs in the refrigerator in plastic bags. "
