Variety Characteristics
Rondar F1 - a hybrid of Dutch selection. It is the property of Syngenta. Since 2002, the hybrid has been included in the State Register, and has since been actively cultivated in Russia.
Appearance
Rondar has bright red rounded roots with white tails. Brief description of appearance:
- Aboveground part. The compact, semi-erect rosette consists of short, semi-oval green leaves. The tops of the leaves are rounded.
- Underground part. Root vegetables are round, shiny, deep red. The diameter of the radishes is up to 3 cm. The pulp is white and delicate in taste. The weight of one mature root crop is from 15 to 30 g.
Yields
In Rondar, ripe root crops reach a size of 2-3 cm. Therefore, the yield of the hybrid is moderate - from 1 to 3 kg per 1 sq. m.
Do not allow root crops to overgrow in order to gain mass. Growing in size, the radish from round turns into ovoid. And most importantly, voids are formed inside it, taste is lost.
Ripening time
Rondar belongs to early ripening varieties. The ripening period - from the moment of germination to harvesting, is 18-20 days.
The hybrid is planted in early spring. Landing is carried out in mid-late April, when the soil warms up to +5 ° C. The exact timing depends on the climate in a particular region.
Disease resistance
Due to its early maturity, the Rondar hybrid is practically invulnerable to most diseases and pests. The growing season of the culture is 20 days, and in such a short period, insects and diseases simply do not have time to attack it.
Where is the best place to grow?
Rondar belongs to new varieties that are capable of ripening, both in the open field and in greenhouse conditions.
The yield and taste of radishes largely depends on the properties of the soil. To grow many tasty root vegetables, you need good soil, loose and fertile.
Attitude to soils:
- Rondar grows well on sandy stones. Cultivated peat bogs are also suitable.
- The optimum acidity of the soil is neutral or light. The acidity can be reduced by adding lime.
- Heavy clay and sandy soils with nutritional deficiencies are not suitable for radishes. On such soils, radishes grow small and tasteless.
Fresh manure or droppings are not added to the soil prepared for Rondar. Introducing fresh organic matter degrades the appearance and taste of the radish.
Advantages and disadvantages of the variety
Hybrid Rondar is not in vain popular among gardeners. This radish has a long list of advantages and few disadvantages.
Advantages:
- long-term preservation of freshness;
- amicable maturation;
- one-dimensionality of root crops;
- pleasant taste;
- early maturity;
- high productivity;
- compactness of the plant;
- resistance to flowering;

Disadvantages:
- a delay in harvesting leads to a change in shape - the radish becomes ovoid, voids in the roots are formed;
- grows poorly on heavy and acidic soils;
- increased demand for lighting and watering.
Planting and growing Rondar radish
Radish Rondar grows well in all conditions - in the sun and in small shade, in open ground, and in greenhouses.
Site selection and soil preparation
Rondar grows best in open, well-lit areas. Slight shading is allowed before or after dinner.
Preparing the soil before planting:
- Outdoors. Superphosphate and potassium sulfate are scattered on the ground - 20 g per 1 sq. Km. m, and urea - 5 g. The same amount of fertilizers can be dissolved in 10 liters of water and poured over 1 sq. m of soil.
- In the greenhouse. Contribute to 1 square. m kalimagnesia - 30 g, potassium chloride - 15 g, superphosphate - 40 g.
Acidic soils are leached with lime (1-4 kg per 1 sq. M, depending on the type of soil) or horse manure (15 kg per 1 sq. M).
Seed preparation
Radish seeds are recommended to be prepared before planting. Correct processing hardens the seeds and accelerates seedling, makes them stronger and more friendly.
Seed preparation procedure:
- The seeds are immersed in water and all that have emerged are removed - they are not viable.
- Seeds are selected by size using a special sieve. Seeds having the same diameter will sprout at the same time.
- The selected seeds are wrapped in a damp cloth and kept for a day in a warm place.
- Warm up the seeds by immersing them for 20 minutes in hot water (+50 ° C). Such treatment will disinfect the seeds and prevent the development of many diseases.
- The heated seeds are enriched with microelements, immersed in a growth stimulator.
- Before planting, the seeds can be soaked in plain, lukewarm water. Soaking time - 8-12 hours.
- After soaking, the seeds are dried by spreading them out on fabrics.
Sowing seeds
Radishes can be planted in different ways - in rows, in holes, in the aisles of other crops. The easiest and most rational way is to plant in rows.
Landing procedure:
- Pry the soil to a depth of 20 cm immediately before planting.
- Make shallow rows - 3 cm deep is enough. The width of the rows is 4-5 cm. Between adjacent rows, make a distance of 8-10 cm.
- Pour warm water over the rows.
- Plant the seeds at 3-4 cm intervals.
- Sprinkle soil over the rows. The layer thickness is 1.5-2 cm. If you sprinkle the seeds with a thicker layer of soil, they will germinate longer.
- Moisten the soil on top to make it easier for the seeds to break through.
Seedling method
In regions with cool and short summers, radishes, like tomatoes and cabbage, are often grown in seedlings. You can grow seedlings in the ground or in twists.
How to grow radish seedlings in soil:
- Fill plastic cassettes with loose and fertile soil - loams and sandy loams with neutral acidity will do.
- Dip one seed into each cassette. Sprinkle with soil and lightly compact.
- Cover the crops with foil and place in the light. Water regularly when shoots appear. Fertilizing radish seedlings is not needed.
The finished seedlings are transplanted into the ground - in the grooves made. Each seedling is removed from the cassettes with a lump of soil and planted in rows at intervals of 3-5 cm. Plantings are covered with a film for 2-3 days until the seedlings are rooted.
Care Features
Radish is growing rapidly and at the same time requires daily monitoring. Planting care is simple, but regular, and depends on the growing method.
In the greenhouse
In the greenhouse, the most illuminated place is chosen for radishes. It is not worth planting Rondar in the shade, otherwise the leaves will stretch out, taking away the strength of the plant. As a result, the root crops will be small.
Features of watering radish in a greenhouse:
- water enough radishes, the frequency of watering - every other day;
- the best time for watering is early morning or late evening;
- it is necessary to moisten the soil 10 cm deep;
- watering is stopped 3-4 days before harvesting.
Other conditions for growing radishes in a greenhouse:
- The temperature is maintained at +18 ° C.
- If the radish is grown in heated greenhouses, then in the winter time, additional illumination is used. For normal growth, radishes need 12 hours of light. The norm of illumination is 1500 lux.
In the open ground
Radish shoots appear 3-14 days after sowing - the timing depends on temperature. After the emergence of seedlings, gardeners begin to care.
Features of caring for radishes in the open field:
- Watering. Radish is hygrophilous, therefore it is necessary to maintain moderate soil moisture all the time. It is important to maintain balance. If you overdo it, excess moisture will cause the radishes to rot. And with a lack of water, radish grows small and bitter.
The greatest need for water is observed during the period when root crops are poured. - Hilling. When the radish sprouts, it is recommended to spud. For this purpose, it is convenient to use a flat cutter.
- Loosening. While the radish is growing, the soil must be loosened regularly to allow air to flow to the roots. After each watering, be sure to loosen the soil between the rows so that a crust does not form.
- Weeding. Weeds are promptly removed, as they impede the growth of root crops and take food from the radish.
- Thinning. At the stage of appearance of the first true leaves, the radishes are thinned out. This is done in the case of thickened plantings, if the planting was carried out exactly according to the scheme, thinning is not needed. There should be a distance of 5 cm between neighboring plants.
- Top dressing. The growing season of radishes is so short that the fertilizer added to the soil before planting is enough for root crops to grow. If fertilizers were not applied for some reason, then feeding is carried out a week after germination. They are limited to a single application of ammonium nitrate (15-20 g per bucket of water). During the formation of root crops, radishes can be fed with an ash solution (100 g per 10 liters of water), infused during the day.
Many gardeners are categorically against feeding radishes, since nitrates accumulate in the root crop.
Harvesting and storage
The radish is harvested gradually - as the root crops grow. It is possible to harvest the entire crop in 2-3 stages with an interval of one week. The readiness of the radish for harvesting is judged visually - by the size of the root crops peeking out of the soil.
Features of cleaning and storage of radishes:
- 2 hours before harvest, the beds are watered. This simplifies pulling out root crops and speeds up the harvesting process.
- Torn root vegetables are cleaned of tops and the tips are shortened to prevent wilting.
- Radishes are folded in plastic bags and stored in a cellar or refrigerator.
- Radishes are stored in packages for no more than a week. Then lateral roots appear at the tip, the root crop coarsens, becomes fibrous and tasteless.
- In vacuum containers, radishes are stored with the tip completely trimmed. Before laying the roots thoroughly washed. In this way, radishes can be stored for up to 2 weeks.
Possible growing problems
Radish agricultural technology is simple and affordable, but novice gardeners often have difficulty growing it.
Typical mistakes when growing radishes:
Problems | Causes of the problem | Decision |
Root vegetables taste bitter and have a fibrous structure. | Water scarcity. | For 1 sq. m of area should have 10 liters of water - with daily watering. When watering every other day - 15 liters. |
The tops grow, but the roots are not formed | Denseness, deep seeding, late sowing, shading. | Compliance with the scheme and sowing depth. The choice of the illuminated area. Trimming the tops. |
Root voids | Overdose of organic fertilizers. Nitrogen causes active growth of tops, which negatively affects root crops. | Wood ash application - 100 g per 1 sq. m. Or make a solution of potassium sulfate (per 1 liter of water - 20 g). |
Arrow formation | Daily weeding and breaking through. | Compliance with radish agrotechnology - frequency of weeding, etc. |
Diseases and Pests
Rondar, like most hybrids, has a high immunity to diseases and pests. But he is not immune from problems, the cruciferous flea is the greatest danger to him.
Rondar radish pests and control measures:
Pests | How do they harm? | How to fight? |
Cruciferous flea | These small, dark beetles eat the tops. Slows the growth of plants. Appear in warm and calm weather. | For prevention, foliage is sprinkled with wood ash or tobacco dust. You can cover plantings with foil to prevent insect attacks. |
Belyanki | It’s not the white butterflies themselves that harm, but their caterpillars. | Spray with a solution of ash (200 g per 10 l of inlet), a decoction of tomato tops (1/2 bucket of tops is poured with boiling water and insisted for half an hour). |
Cabbage fly | The fly larvae eat root crops, grinding holes in them. | Harvesting plant debris and deep plowing in the fall. Compliance with crop rotation - do not plant radishes after cabbage. |
It is not recommended to use insecticides when growing radishes, since poisons are actively accumulating in root crops.
Diseases that can affect Rondar radish:
Diseases | Symptoms | How to fight? |
Powdery mildew | White bloom on leaves, deformation and drilling of leaf plates. | Treatment with fungicides "Ridomil Gold", "Ditan". |
Bacteriosis | Blackening of leaf veins. Leaves dry and crumble. | Disinfection of planting material in hot water. |
Gray rot | Brown spots appear on the roots, causing them to rot. | Culling sick plants. Preventive spraying with fungicides. Collection of plant residues. |
Reviews of gardeners
Victoria, 48 years old, housewife, Samara region Our climate is not particularly favorable for radishes - spring is too short. But Rondar pleased me - it is a very early ripening variety, ripens together, quickly, so that fleas and flies do not have time to harm it. The radish is very tasty, the pulp is juicy and without voids.
Khariton Ivanovich, 67 years old, pensioner, Maykop. I always planted our radish, but then I decided to try the Dutch seeds. They cost more, but radish Rondar did not disappoint me. It grows quickly, all the juices go to root crops, and not to the tops. Radishes are all smooth, neat, ideal for sale in both appearance and taste.
