The supremely early variety "Riviera" fell in love with our farmers and gardeners for its productivity, drought tolerance and excellent taste. This Dutch variety is ideal for growing marketable potatoes - several crops can be harvested per season.
Origin of the variety
Thanks to selection, potato varieties that successfully grow in any climate have been bred, one of them is the Riviera. This is the fruit of the work of Dutch breeders from Agrico Holding, an association of potato farmers. The company has been operating since the 80s. Twentieth century, growing tubers on their fields for seeds. In the State Register of Plants of the Russian Federation, the variety "Riviera" was introduced in 2013. Agrico Holding also owns the most popular potato varieties - Ariel, Romano, Marlene, Sante and others.
Grade description
Variety "Riviera" is able to produce high yields even in the driest seasons. Suitable for growing under a film. In the southern regions have time to grow two crops "Riviera". Digging for obtaining tubers for food can begin from 35 days from the moment of emergence of seedlings. Features of the variety "Riviera" - in table 1.

The bushes are distinguished by strong stems and a powerful root system. A distinctive feature is the rapid growth at the beginning of the growing season. The tubers have shallow eyes, so they are convenient to peel.
Characteristics of the variety "Riviera"
Due to its characteristics, the variety "Riviera" is ideal for cultivation in Russia, Ukraine, Moldova. This Dutch potato has the following qualities:
- Early ripening. Already on the 40th day after emergence, tubers can be dug up - they acquire marketable weight.
- High yield. On the 35th day it is 280 kg / ha, on the 40th - 450 kg / ha.
- Drought tolerance. The variety tolerates the absence of watering, giving a decent harvest, even in the dry season. Plants have a powerful root system that provides the bush with moisture and nutrition.
"Riviera", thanks to its early maturity, manages to complete the vegetative cycle before the summer heat begins. The variety is suitable for cultivation in the hottest regions.
- Good tolerance to mechanical damage. During harvesting, the integrity of the tubers is 87-92%.
- The variety is resistant to disease. It resists cancer, viral diseases, nematodes. May be ill with late blight and scab.
- Good keeping quality. The tubers harvested during the second harvest are especially well preserved.
- High nutritional qualities. Potatoes of this variety, when assessing taste on a 5-point scale, gaining 4.8 points.
- Special purpose - for food in a young form and for long-term storage.
The variety is unpretentious, but has preferences in relation to soils - it grows best on light soils.

Potato "Riviera" refers to table varieties. Mashed potatoes and salads are made from it, fried. Differs in the average digestibility of tubers. Gardeners are unanimous - the most delicious tubers are those dug in the early stages of maturation.
Advantages and disadvantages
Riviera is an excellent potato variety worthy of the attention of producers and gardeners who grow crops for their own needs. The pros and cons of the variety are in table 3.
Table 3
pros | Minuses |
Fast ripening | Exposure to certain diseases (scab, late blight) |
Adaptable to different climatic conditions | Demanding on the soil - good productivity is observed on neutral and loose soils |

Low, low% waste | |
Good transportability |
Seed preparation
The maximum growing season is 45 days. In order to harvest potatoes early, and have time to plant a second crop, the seed material is germinated.
Table 4
Features of the preparation of tubers for planting | |
Selection time | Fall. Small tubers weighing 40-70 g are selected for planting - they are stored separately from the potato mass. |
Germination | The tubers sprout. The height of the sprouts is 0.5-2 cm. |
Germination Duration | 14 days |
Germination temperature | 12-15 ° C |
With the onset of spring, tubers set aside for planting are sorted out - you need to remove rotted or frozen root crops.
Potato "Riviera" can be planted for germination 2 months before planting, creating favorable conditions for the emergence of sprouts - then by the time of planting on the tubers the root system begins to form. This method reduces the ripening time. So that the germination is quality, the tubers are turned over from time to time.
There are three methods of germination:
- In drawers. This is the traditional way - tubers are laid out in boxes in 1-2 layers. They are exposed to light at 15 degrees for 15 days.
- In packages. The tubers are germinated in transparent plastic bags with pre-made holes. Seeds are put in packages and, tied, hung up so that light falls on the bag, but not the open sun. Sprouts quickly appear due to the greenhouse effect.
- Withering. Tubers are laid out in the basements and in the attics.
If the spring is wet and cold, and the sprouted potatoes are too early to plant, they transfer it to boxes with sawdust - they are put to the bottom, saturated with liquid fertilizer.
Thanks to germination, the yield increases to 100%, and the terms are shifted forward a week.
Growing potatoes from seeds
If you grow the same variety of tubers, then after 5-6 years of cultivation, it begins to degenerate. Signs of degeneration of the variety:
- yield decreases;
- the size of the tubers is reduced;
- immunity falls - plants begin to hurt.
We have to update the seed material. But elite tubers are expensive. In addition, there is a risk of buying potatoes that do not meet varietal characteristics. It is much more profitable to grow root crops from seeds.
Where to get the seeds:
- collect from the bushes - you need to choose the most powerful and productive plants;
- buy in specialized gardening centers.
There are two options for growing potatoes from seeds:
- Sowing in soil. Tubers grow small - they are used for planting for next year.
- Seedlings. Seeds germinate in March-April, keeping them for several days in a damp rag.
The procedure for growing seedlings:
- Prepare nutritious soil. Take 1 part of the land and 4 parts of peat. Add fertilizer.
- Germinated seeds are sown in containers. The distance between adjacent seeds is 5 cm. Between the rows is 10 cm.
- Seeds sprinkled with earth, sprayed from the humidifier.
- The containers are closed with a transparent film and placed in a warm, bright place. Periodically moisten the soil, avoiding drying out or waterlogging. The room is regularly ventilated.
- The first shoots appear after 10 days. When two leaves appear, seedlings are planted in separate glasses - they must have holes for draining water.
- Caring for seedlings, in addition to watering, requires turning the glasses - to ensure uniform illumination and prevent stretching. Also, the cultivation of row-spacings is necessary - for air to reach the roots.
In order for the seedlings to take root better, they give her top dressing - urea solution (1 g per 1 liter). Then the seedlings are fed monthly.
When the seedlings grow up, they harden it - they take it out to the open air for half an hour. Gradually, the time of "hardening" is increased. Before planting seedlings in the ground, it is kept on the street for several days. When the threat of frost disappears, seedlings are planted in the ground. Features planting potato seedlings:
- top dressing is added to the wells - humus (300 g) or ash;
- plants are buried in the soil, only three leaves should remain on its surface;
- at first, seedlings are covered with agrofibre - so that it is not damaged by temperature extremes and direct sunlight;
- when the weather is stable and stable, the agrofibre is removed;
- first the plants are watered often - every two days, then - like ordinary potatoes.
Harvest from seeds - small potatoes, which become a source of elite potatoes for the next five years.
Seedlings can be grown not only from seeds, but also from sprouts. To do this, the sprouted tubers break off the sprouts - they are transplanted into separate containers.
Dates and rules of landing
Rules for planting varieties "Riviera":
- It is recommended to plant potatoes in an open area well lit by the sun.
- Ground requirements - low groundwater level, not more than 70 cm above ground level.
- The soil for planting is dug up twice:
- autumn 15 cm deep;
- in the spring - re-digging.
- In the fall, fertilizers are applied - manure (10 kg per square meter).
- Tubers need to be planted in moist and well-warmed soil - up to + 10- + 12 ° C.
In the middle lane, the planting of tubers begins not earlier than mid-April. Landing time depends on the region and its climatic features, as well as on the weather in a particular season.
Ideal for planting are tubers the size of a chicken egg, weighing 30-60 g.
If you plant potatoes in April, then by the end of May you can already harvest. The main thing is not to rush to the deadlines - the tubers will still not begin to germinate until the soil warms up to a sufficient depth. The optimal time for planting, according to popular signs - when the leaves of birches will increase to the size of a nickle.
Step-by-step instructions for planting potatoes:
- The soil is being dug. Lime or dolomite flour is added.
- Rows are marked "under the cord." The interval between the rows is 65-70 cm.
- Fertilize is thrown into the wells and put tubers. The interval between adjacent potatoes is 35-40 cm. The tubers are placed up by sprouts.
- They fill the holes with earth. The soil layer above the potatoes is 6-10 cm.
Growing Features
The agricultural technology of the Riviera variety is extremely simple. Among the features of growing this variety, it is worth highlighting rare watering - the Riviera has to be watered only in severe drought.
The variety grows well on loamy, peat and loamy soils with a high content of nitrogen and potassium. To potato spoil, gardeners often feed potato plantings with humus or rotted manure. Farms usually feed potatoes with liquid fertilizers - slurry or chicken droppings. To increase yields, you need a double digging of the soil - in autumn and spring.
Doctor of Agricultural Sciences talks about the features of cultivating the "Riviera" variety, its yield and processing methods:
Watering
In case of heavy rains, it is recommended to feed the plants with dry fertilizers. And in the drought, you need to dig up the bushes - in time to stop the spread of late blight on tubers. The bushes have a powerful root system, but during the formation of the tops, even they can not cope with drought - plants need to be watered.
If the weather is dry when the shoots appear, the number of ovaries decreases.
Table 5
Riviera Watering Rules | |
Number of waterings per season | 2 |
1st watering. Shoots grew to 10-15 cm. | at least 3 liters of water |
2nd watering. The period of formation of tubers - begins with flowering. | 2 liters of water per plant |
Humidification depth | 25 cm |
Average watering rate for one bush | 4 l |
If you comply with the terms of potato irrigation, the tubers will be smooth, unaffected by scab and without cracks.
Lack of watering in a drought will lead to a poor harvest - tubers grow small.
If potatoes are grown in large areas, it is recommended to use:
- drip irrigation - moisture is supplied to the roots of plants;
- sprinkler - a technique that simulates natural rain creates a humid environment.
Riviera is more suitable for irrigation by sprinkling, as this method not only irrigates the soil, but also flushes harmful insects from the foliage.
Hilling
Loosening is a mandatory agricultural measure when growing potatoes. The roots of this plant more than others need oxygen - for the growth and filling of tubers.
Hilling objectives:
- prevent exposure and diseases of root stems;
- provide increased oxygen access to the tubers - so that they are better poured;
- freezing of young sprouts at lower temperatures is prevented;
- weed control.
During the season, carry out two hills:
- First - when the tops grow to 14-16 cm.
- Second - after 2-3 weeks, before flowering.
Hilling can be:
- Manual - using a chopper or a plane cutter.
- Mechanized - cultivator, walk-behind tractor, other agricultural machinery.
If you do not spud potato bushes, crop losses can be 30%. It is recommended to hight planting in the mornings and evenings - during weak solar activity. The best time for hilling is after watering or rain. Be sure to loosen and weed the weeds in the space between the rows.

Feeding and mulching
Riviera is an unpretentious variety, but its yield on fertilized soils will be much larger. Trace elements introduced into the soil:
- increase the resistance of plants to diseases;
- increase the starch content in tubers - potatoes will be tastier and crumbier;
- increase shelf life and shelf life of tubers.
In spring, the soil must be fertilized (proportions for one hundredth):
- potassium sulfate - 2 kg;
- ammonium nitrate - 1 kg;
- double superphosphate - 1 kg;
- ash - 5 kg;
- nitroammophosk - 3 kg;
- nitrophoska - 5 kg.
The timing of feeding after planting tubers is shown in table 6.
Table 6
Application Dates | Mineral fertilizers per 1 sq. Km. m | Organic dressing per 1 sq. Km. m |
Before the first hilling - when the seedlings reach 12-14 cm | Superphosphate (20 g) and urea (10 g) | 1. Bird droppings diluted in water (1:10). Consumption per 1 bush - 2 liters. 2 Manure with water (1:10). 3. Herbal infusion - weeds fermented in water. Poured into the hole. 4. Nettle infusion - fermented and strained infusion bred with water. Watered every 10 days. |
During flowering | 100 g of ash is a source of potassium | |
At the end of flowering | Top dressing - superphosphate (100 g) per 10 liters of water. The consumption rate is 3 liters per 1 hundredth. | |
After flowering | For intensive tuber growth, superphosphate is added - 30 g per 10 l, or Mag-Bor - 15 g per 10 l |
It is recommended to mulch the beds with hay or sawdust. A 5-10 cm layer perfectly retains heat and inhibits weed growth. As a mulch, a dark film is also used.
Today, many gardeners grow potatoes in mulch:
- On the plot, mow the grass and lay the tubers sprouts up.
- Tubers are covered with hay or freshly cut grass. Mulch layer - 10 cm.
- As the grass settles and the shoots germinate, they plant hay - seedlings up to 15 cm in height should remain on the surface.
- Shoots are watered and fed.
- When the bushes bloom, wait another 2-3 weeks and harvest - just lift the mulch for this.
The success of this interesting method depends on the variety of potatoes, the composition of the soil and the experience of the gardener. When growing potatoes, the main thing is not to overdo it. If the plantation is flooded with water, there will be a risk of late blight - a disease that can destroy half the crop. If you overfeed the soil with fertilizers, the plants will be sick, which will also lead to loss of yield.
Diseases, pests and methods for their prevention
The variety withstands most viral and bacterial attacks. The only thing that can seriously threaten him is late blight. Preventive measures must be taken to prevent disease and harm from insects.
Before planting the tubers, it is recommended to treat with “Prestige” - a remedy for the Colorado potato beetle. Tubers, laid out in one layer, are treated with the drug. After spraying on one side, the root crops are turned over to treat the other side.
To increase the immunity of plants, it is recommended to spray the bushes with Fitospirin.
Means of combating diseases and pests - in tables 7 and 8, respectively.
Table 7
Disease | Symptomatology | Treatment methods | Prevention |
Late blight |
| The bushes are sprayed with a 1% Bordeaux liquid or 0.5% copper chloride solution. |
|
Macrosporiosis |
| They are treated with the preparation “Growth” (40 g per 10 l) or “Arcerid” (50 g per 10 l). | Spraying with Bordeaux fluid throughout the growing season. Spraying frequency - once a week. |
Blackleg |
| They tear up a diseased plant. Ash with copper sulfate (1 cup and 1 tsp., Respectively) is poured into the hole. | Before budding, the bushes are treated with copper sulfate (for 10 liters of water - 1 tbsp. Vitriol and 40 g of laundry soap). |
Dry rot |
| Tubers affected by the disease are not treatable. | Prevention of mechanical damage to tubers. Compliance with storage rules. |
Table 8
Pests | Signs of defeat | Ways to fight | Prevention |
Colorado beetle | Larvae and beetles eat leaves to the veins. | Collect eggs, larvae and beetles by hand. Treatment with Boverin (30 g per 10 L of water) or Bitoxibacillin (50 g per 10 L of water). Spraying with a solution of urea (100 g per 10 l) | Autumn digging of the soil. |
Wireworm | Strokes in the tubers. | Spraying the bushes with the preparation "Karate" (2 ml per 10 l of water "," Decis (1 g per 10 l) or "Actellicum" (ampoule per 2 l of water). | The soil before planting tubers is treated with a solution of potassium permanganate (5 g per 10 l of water). |
Medvedka | Holes in the beds. Affected bushes fade and die. | Processing "Medvetoksom" - it is introduced into the soil. Depth of application - 5 cm. Consumption - 2 g per 1 sq. Km. m | Autumn digging - as deep as possible. |
Potato scoop | Nibbles the base of the stems, damages the tubers. | Treatment with Fitoverm (4 ml per 2 l of water) or Agrovertin (5 ml per 1.5 l of water) | Destruction of weeds and digging the soil. |
Potato moth | Ovipositions are visible on stems, tubers, and leaves. There are holes in the tubers. | Treatment of affected tubers with a 1% solution of Lepidocide or Bitoxibacellin (100 g per 10 l of water) | Weed control. Hilling bushes. Compliance with storage standards. |
It is noticed that the riviera is liked by the bear more than other varieties. If several varieties of potatoes grow in the garden, the pest will choose the “Riviera”.

Harvesting
The readiness of the crop can be judged visually and by time. By the 40th day after emergence, the stems fall and wither. Two weeks before harvesting, the tops are completely harvested - this is done to improve the keeping quality of root crops.
Harvesting of the first crop is carried out in late June-early July. In the southern regions where two crops are grown, the second harvest is in the month of September.
What you need to know about cleaning:
- Seed material is taken immediately - during the harvest. Potatoes selected for seeds are laid out in a sunny place - so that it turns green. This is done to improve germination.
- The tubers extracted from the soil are laid for drying - directly on the inter or under the canopy.
- Tubers are sorted, rotten and diseased are removed - they can infect healthy ones.
- The walls of the room in which the potatoes will be stored, and the tubers themselves, are sprayed with "Antiburn" - this is an effective biological product that can increase the% of keeping quality. It is recommended to whitewash the walls of the cellar with lime, and line the bottom with matting.
- The tubers are treated with a solution of copper sulfate 0.2 g per 10 l of water. This will improve the safety of root crops.
- Storage temperature - + 2 ... + 4 ° C. If it is warmer, the tubers will sprout.
- Over the winter, potatoes are picked 2-3 times, removing spoiled tubers.
For digging, gardeners usually use forks - they dig a row, a little away from the holes, so as not to damage the tubers.
Storage methods
Potatoes can be stored in the basement, in piles and trenches. When laying tubers for storage in basements, it can be stored in this form:
- In bulk. The easiest and oldest way. It is used if there is little potato. The disadvantage is that foci of rot may form, causing large losses.
- In drawers. The best boxes of coniferous wood - they are less affected by fungus and bacteria.
- In containers. The best option for farmers and gardeners growing potatoes for sale. The container usually holds 500 kg of potatoes. Tanks have slots - for ventilation. Containers can be stacked on top of each other in several rows.
- In bags or nets. A convenient way - bags are placed on shelves or one on top of the other. Root crops are provided with good ventilation. It is better to use bags made of natural materials. But today, nets are used more often - it is cheap and convenient.
If you shift the tubers with plants that produce phytoncides - pine or spruce branches, rowan leaves, potatoes are better preserved. The formation of rot on root crops is also hindered by bitter wormwood, rot, elderberry, fern, onion peel, and garlic.
Professional Tips
To obtain high yields, it is necessary to follow the cultivation agricultural technique. The tips of experienced farmers will help you achieve your goals:
- Do not plant the "Riviera" on heavy rocky soils - tubers will grow slowly, and they will grow deformed.
- Be sure to dig the site twice a year - in autumn and spring. The soil will become loose and enriched with oxygen.
- Potatoes grow well after cucumbers, squash, onions, zucchini, pumpkin, and legumes. The risk of infection with pathogenic microbes is reduced, the likelihood of high yields is growing. It is not recommended to plant potatoes in the area where garden strawberries used to grow.
- To scare away the Colorado potato beetles, plant beans, coriander, tansy or nasturtium in the aisles. To prevent late blight, plant onions and garlic next to potatoes.
- When planting small tubers - up to 30 g, put 2-3 in each hole.
- You can’t grow potatoes in the same place for years - this will deplete the soil, and the tubers will be smaller and smaller.
Reviews gardeners and farmers
Raisa Molochnikova, 50 years old, Belgorod region Last year, she planted the Riviera in two areas at once - one was very fertilized with manure, the second - ordinary. On the first, many large tubers grew, bushes abundantly bloomed. In the second section, the vegetation ended earlier than in the first, the flowering was modest, I dug up the first potato in early June. I did not like that the tubers are very boiled, but the mashed potatoes come out very tasty.
Leonid Shishkov, 56 years old, Bryansk region. Taste the Riviera very much. True, the bear also fell in love with the variety, it damaged many bushes. The variety is very early, fresh potatoes appear in the month of June. Harvest variety - planted only half a bucket of trifles at the dacha, and dug 5 buckets of large tubers. The bushes are strong, practically do not get sick, you do not need to spend money on care and poison.
Alexander Mitin, 34 years old, Crimea, farming. Riviera is one of the best varieties. You can take two harvests of good marketable potatoes. Very responsive to fertilizers. Ideal for high-risk areas - can withstand any drought. Lying, large, well tolerates transportation, tubers are delicious, beautiful in appearance. It’s profitable to sell.
