Did you know? In Russian zoos, flamingos eat carrots to preserve the color of their plumage. In natural conditions, small crustaceans provide birds with bright color.

Detailed characteristics and description of the variety

• Appearance (shape and color of the root crop). Carrots grow in a cylindrical shape with a blunt end, weighing from 90 to 110 g. The length of the carrot reaches 20 cm, the diameter is up to 4-5 cm. The surface, pulp and core of the root vegetable are intense orange in color.
• Sowing time. For the NIIOH 336 variety, the average planting time is applicable - late spring, when stable warm weather has already established and when the danger of return frosts has passed.
  In the central zone, this time falls on the third ten days of April; in Siberia, planting begins no earlier than May. In the Southern region, sowing dates traditionally begin earlier than everyone else - in the first and second ten days of March.

  But this variety can also be planted before winter, in late October - early November, when the air temperature has not yet dropped below 5°C.

• What is the yield from 1 hectare. The variety is productive - from 1 hectare you can harvest from 28 to 54 tons of carrots.
• Purpose of the variety and keeping quality. This variety has high taste and also contains an increased amount of carotene. According to its intended purpose, it is best suited for fresh consumption, as well as for canning. Keeping quality indicators are at the level of 82-92%.
• Growing regions. The variety is approved for cultivation throughout Russia with the exception of the Northern, Northwestern and Ural regions.
• Where is it recommended to grow? Carrots of this variety are recommended for growing in open ground.
• Disease resistance. The NIIOH 336 variety does not resist the most common carrot diseases very well. Pre-sowing seed preparation is an excellent prevention of many diseases, but it is not always enough.
• Maturing period. The variety is mid-season, since the growing season from the moment the first shoots appear is 110-120 days. However, in regions with a warm climate, ripening occurs much faster - in 80-90 days. Find out about other varieties of carrots based on their ripening time.
• What types of soil does he prefer? The variety prefers light, loose soils with low acidity.

Agricultural technology

Sowing is carried out in the spring, in April - May. Our heroine prefers cultivated and fertilized soils, so before sowing, do a deep digging and apply fertilizer. But remember that it is unacceptable to exceed the required nitrogen norm, otherwise this leads to the accumulation of nitrates in root crops and a sharp decrease in their keeping quality. The crop does not tolerate fresh organic matter; after its application, the plot can only be used for carrots the next year. But potash fertilizers are more preferable. The best predecessors in crop rotation are cucumbers, tomatoes, legumes, early cabbage and potatoes, which also prefer soil with neutral acidity. Watering should be done carefully; if there is excess moisture, the vegetable stops growing, but the soil should not be allowed to dry out. Sow the coated seeds at a distance of 4 - 5 cm from each other. The row spacing is about 20 cm. The crop is perfect for pre-winter sowing.

NIIOH 336 is a very popular mid-season variety. Its main value lies in its high productivity, excellent taste and the ability to store crops for long-term storage. Considering that the variety is intended for cool regions, its resistance to unfavorable conditions is of great importance, thanks to which it is possible to avoid flowering.

Growing

1. For carrots, it is important to choose open, well-lit areas. A few weeks before planting, it is recommended to add humus or compost to the soil (at the rate of 4 kg/m²). The seeds should also be prepared in advance - soak in a weak solution of manganese or use the preparation "Hom". This treatment will disinfect the seeds and also increase their immunity against diseases.
2. Sowing is best done on a sunny day. First, grooves are made in the soil up to 1-2 cm deep. The distance between the seeds is left about 0.5 cm, then the soil is leveled and watered abundantly.
3. Further care involves thinning - the first thinning should be done two weeks after sowing. The second thinning is after about three weeks. The distance between plants is left at least 5 cm. If thinning is not done, the carrots will begin to deform due to lack of space or grow too small.
4. The variety needs sufficient watering - depending on weather conditions, you need to water the root crops once every 4-7 days. It is recommended to water carrots between the rows, and not under the bushes.
5. Carrots respond well to fertilizers, therefore, during the season you can do three feedings:
   During periods of intensive growth, you can use superphosphate (50 g per 10 liters of water).
6. At the time of flowering, potassium nitrate (30 g per 10 liters of water) is suitable.
7. During the fruiting period, you can add ammonium nitrate (30 g per 10 liters of water).

Features of planting and care

Niiokh 336 carrots can be planted in spring and before winter. In the first case, planting should be done after the snow melts, when the ground warms up to +5-8 ° C, and in the second, in October-November two weeks before frost.

For this variety, you need to choose flat, open areas where water does not stagnate. Niiokh 336 carrots show good performance when planted in loamy and sandy loam soil with a neutral acidity level. You need to prepare the area in advance. It must be dug up and humus added at the rate of 5 kg per 1 sq. m. m, as well as superphosphate (25 g) and potassium sulfide (15 g) for the same area size.

Niiokh 336 carrots should be planted in rows, maintaining a distance of 20 cm between them. The optimal depth level is 2 cm. Carrot seeds are characterized by slow germination, and seedlings appear when weeds grow massively. And since in the spring a crust regularly forms on the soil, for full development the sprouts need access to oxygen to the root. To ensure this, it is necessary to mix Niioh 336 carrot seeds with radishes, lettuce or peas. Their early shoots will mark rows, which will allow for timely loosening of the soil and removal of weeds between them.

To successfully grow root crops, you need to thin out the seedlings. There should be at least 4 cm between sprouts.

Carrots of this type need regular watering in the absence of seasonal rains. But at the same time, it does not tolerate stagnation of moisture in the soil. The crop bed should be moistened twice a week.

Variety Niiokh 336 responds well to potash fertilizers, but reacts poorly to organic matter. Root feeding should be carried out twice a season, using potassium sulphide 25 g per 10 liters of water.

Carrot Niiokh 336 does not need hilling

Important! The best predecessors for root vegetables are potatoes, tomatoes, cabbage, onions, and cucumbers.

Harvest and storage

Like other varieties, NIIOH 336 must be collected before frost. In addition to calculating the date for harvest based on the ripening time of a given variety, you can also focus on the yellowing of the lower leaves.

As soon as the soil on the pulled out root crops has dried, the tops should be removed.

Before storing, carrots are sorted out and damaged or diseased roots are set aside. To increase the shelf life of the crop and protect it from diseases, you can dust the carrots with chalk powder. The method of sprinkling carrots with pre-calcined wet sand or pine sawdust is also practiced.

Diseases and pests

This variety has average immunity to most diseases, so it is important not only to carry out preventive preparation of seeds for planting, but also to know how to combat diseases:

• Treatment with Fofatox solution will help against late blight.
• For root rot - a solution of colloidal salt.
• For powdery mildew, the drug “Regent” is suitable.

Parasites can also often become a headache for gardeners growing this variety.

1. To combat aphids, you can use the drug "Oxychom".
2. The drug "LuxBor" will help against midges.
3. A solution of wood ash can be used against the Colorado potato beetle.
4. From the mole cricket - Bordeaux mixture.

Caring for carrots

Caring for carrots involves timely weeding, watering as needed, loosening and other agricultural practices.

The beds should be kept clean and weeds should be regularly removed, which take away nutrients from the carrots, shade the crops and create favorable conditions for the spread of pests and diseases. Together with weeding, loosening can be done between the rows.

Thinning allows you to avoid the appearance of crooked root crops and increase their size and quality. Usually 3 thinnings are carried out per season:

• The first is carried out when the seedlings reach 2 cm in height, leaving a distance between them of at least 1 cm.
• A week later, a second one is carried out, leaving a distance between seedlings of at least 2.5 cm.
• When the seedlings reach 10 cm, a third thinning is carried out, leaving a distance between them of at least 5 cm.

In the future, you can thin out the carrots when the root crops reach 1 cm in diameter and use the vegetables after thinning as early vitamin products.

Water carrots at the beginning of the growing season and in the absence of rain, right to the root, avoiding erosion of the soil and exposing the root crops. To do this, watering is carried out in two steps, waiting until the water is absorbed after the first. During dry periods, the frequency and volume of watering is increased.

Irrigation should be carried out in the morning or evening to retain moisture in the ground longer and not burn the plants. The drip method of irrigation is considered ideal, which allows you to use water economically and regulate the flow of moisture to the roots. Mulching beds allows you to maintain soil moisture for a long time and reduce the volume and frequency of watering.

Carrots are fertilized several times a season during the period of active growth and formation of root crops. A mixture of complex mineral fertilizers and organic matter has a good effect on plant development in the spring. Solutions of potassium-phosphorus fertilizers (50 g of superphosphate, 30 g of potassium nitrate, 30 g of ammonium nitrate per bucket of water) are suitable. When re-feeding after 2 weeks, the dose of fertilizer is halved.

For normal development, root vegetables need a lot of potassium. Organic fertilizers for carrots should be applied only in diluted form (1:10), since their excess can lead to rotting of the root crops. Twice a month, you can sprinkle a thin layer of ash over the garden bed as a potassium fertilizer to improve the growing season and prevent diseases. Complex mineral fertilizers should be selected with a high content of sodium, boron and sulfur.

NIIOH carrots are resistant to negative environmental factors, but are affected by pests and diseases. When growing, preventative measures should be taken, and in case of damage, systemic means of control should be used:

• The soil is treated with ready-made biological fungicides (Fitosporin, Baktofit, Grunt Zashchita, etc.) to reduce the infectious fungal background and protect against pests.
• In the spring, against carrot flies, wireworms and psyllids, when 2-3 leaves appear, they are sprayed with Decis, Actellik, Splender, Aktara, Bazudin.
• If affected by powdery mildew or brown spot, treat with fungicides (Regent), and with anthracnose - with Khomus.
• You can get rid of root rot with solutions of colloidal salt.

The dissolution of drugs and their dosage must be carried out according to the instructions. Joint planting of carrots, onions and garlic, as well as sowing other plants (marigolds, calendula, sage) can provide protection from pests.

Various problems during cultivation and ways to solve them

Failure to comply with the rules of agricultural technology, unfavorable weather conditions, poor-quality seed material and other factors can lead to certain problems when growing carrots.

Knowing how to solve these problems, with timely actions you can save the future harvest or avoid repeating the same mistakes and problems next season:

• The shoots or tops turn yellow, stretch out and weaken - if the cause is parasites, then the drugs “Aktara”, “Ecogel”, “Zircon” are used to combat them.
  In case of disease with phomosis (seedlings begin to turn yellow from below), brown spot (seedlings first turn yellow at the edges and then turn brown) or rhizoctonia, the plants will have to be destroyed, since with further storage they can infect the rest of the crop.
• White core inside - the cause may be poor-quality seed material, as well as an excess of nitrogen against a background of deficiency. In the second case, adjusting the fertilizer application schedule will help solve this problem.
• Root crops crack - this happens due to uneven watering, excess fertilizer, heavy soil, and overripening of an early variety.
  It is important to monitor the uniformity of watering and apply fertilizers correctly (especially be careful with nitrogenous ones). If the site has heavy clay soil, you should give preference to varieties with short roots or plant carrots in raised beds.
• Carrots grow unsweetened and dry - this may be due to the characteristics of a particular variety, as well as a lack of watering or fertilizer.
• Deformed root crops - the reasons for this phenomenon may be poor soil preparation (many stones), lack of watering in the first month after planting, incorrectly selected fertilizers (you cannot use manure, potassium chloride and potassium salt) and pest invasion.
• Carrots grow very small - this may be due to the characteristics of a certain variety, lack of sun, or, conversely, excessive heat. In the latter case, it is worth increasing the volume of watering.

Perhaps the soil on the site is unsuitable - too heavy or too acidic. Adding sand at the stage of preparing the soil for planting, as well as lime or dolomite flour, will help correct this situation next season.
