Rosalind potatoes are a product of the work of German breeders. Recommended for growing in several regions: Central, East Siberian, Central Black Earth, North Caucasian.
In early potatoes Rosalind bushes form semi-erect, medium height. The bright green leaves of an open type grow medium in size.
Tubers ripen with a mass of 60-110 g, and up to 16 potatoes can form in one bush. Oval-rounded fruits stand out with a red smooth skin and yellowish pulp (as in the photo). Starch content 12.2-17%. It takes 53-61 days to ripen the crop. The Rosalind variety is distinguished by excellent keeping quality (95-97% of tubers are preserved).
If you pre-germinate the planting material, then the rate of maturation of the tubers increases. Therefore, it is not surprising that in the southern regions experienced gardeners harvest twice a season.
Advantages and disadvantages
Characterizing the Rosalind potatoes, it is easy to highlight the positive and negative aspects of the variety.
Susceptibility to late blight. Precautionary measures - pre-planting potatoes. Experienced gardeners also recommend disinfecting the soil.
Advice! When choosing a plot for potatoes, it is important to take into account the rules of crop rotation. The best predecessors of the crop: peas, vetch, lentils - any annual legumes.
Fertile soil is an important guarantee of a bountiful harvest. Loose, well-ventilated and moist soils are more suitable for potatoes of the Rosalind variety.
Preparatory stage - disinfection of planting material and soil:
- The tubers are processed with special means. Kolfugo Super is a liquid seed dressing agent. It neutralizes many diseases, has a long duration of action, promotes the friendly emergence of seedlings, is not phytotoxic. The product adheres well to the surface of the tubers - it is resistant to water washout (during watering or during rains). The consumption rate is 2 ml per kilogram of potatoes. It is to combat late blight that Fitosporin-M is used. Consumption - 10 ml per kilogram of material.
- For cultivation of the land use "Force" or "Aktar". These products disinfect the soil and help fight the wireworm after planting the potatoes. The recommended dose is 0.5 kg per hundred square meters. To simplify the processing process, it is better to scatter the granules during the planting of the tubers (the product should be close to the root system of the plants).
Planting work is carried out after the threat of frost. Soil temperature at a depth of 8-10 cm should be at least + 5-8 ° C. Rows of Rosalind potatoes are best positioned in a north-south direction. Holes 8-10 cm deep are dug with a distance of 65-70 cm between rows and a step of 25-30 cm in a row.
Rosalind is one of the varieties that respond quickly to high-quality agricultural technology. And this should not be neglected, because with proper care, the yield increases by 15-20%. The following activities should be constantly carried out:
- shallow loosening, due to which the air permeability of the soil increases;
The bushes should not be flooded. In order for the water to flow well to the roots of the Rosalind potato, it is advisable to make grooves parallel to the rows.
Hilling and feeding
These are the most necessary procedures, without which it is difficult to expect a good harvest. It is recommended to do this work in cloudy weather when the ground is wet.
When hilling the Rosalind potato bush, moist soil is scooped up to the roots. This procedure will allow you to get the maximum yield, as it promotes the formation of new tubers. An additional effect is provided by loosening the soil around the plants, in which the earth is saturated with air and dries out more slowly. The first time the potatoes of the Rosalind variety are spud after the emergence of shoots. During the season, the bushes are usually huddled twice with an interval of three to three and a half weeks.
How to feed potatoes
Gardeners who prefer organic fertilizers can use semi-matured manure or compost (a mixture of peat and manure). If you immediately pour wood ash into the hole or trench, you can get a greater effect. The excellent yield of Rosalind potatoes also ripens with the use of inorganic fertilizers.
Nutrient formulations are applied in several stages. It is important to choose the right mixture for each time.
- For the first time, fertilizing is added to the soil after germination. Nitrogen-containing compositions are used, ammonium sulfate, ammonium nitrate. Since potatoes of the Rosalind variety must quickly build up a green mass. You can use a solution of 15 g of urea and 500 ml of mullein per 10 liters of water.
- As soon as the buds appear and the tubers begin to set, the plants are re-fertilized. At this time, Rosalind potatoes need potassium and phosphorus. Therefore, a mixture of 15 g of potassium sulfate, half a glass of wood ash, 15 g of superphosphate, diluted in 10 liters of water is suitable.
- Three weeks before digging up Rosalind potatoes, the soil is fertilized with a solution of superphosphate (30 g) and slurry (25 ml), diluted in a bucket of water (10 L). About half a liter of fertilizer is poured under each potato bush.
Do not neglect top dressing, especially organic ones. Since these additives improve the structure of the earth, they make it looser.
Diseases and pests
The main danger for the Rosalind variety is late blight, which damages the tubers, the aerial part. The first signs of damage are darkened spots on the leaves. The disease leads to the death of the foliage, and the infected fruits rot during storage. Chemicals are a reliable means of control. Tops with a height of 25-30 cm are sprayed with special solutions (Bordeaux liquid, copper sulfate). Before flowering, Exiol, Epin are used if damp cool weather is established. When it is warm and dry, you can use Kresacin, Silk. As soon as the bushes bloom and the tubers begin to actively form, it is recommended to spray the Rosalind potatoes with Alufit.
Important! Only calm dry weather is suitable for processing potato planting.
It is known that disease is easier to prevent than to cure. This expression also applies to the plant world. The most popular preventive measures:
- plant only healthy material, do not have potato beds in damp lowlands;
- thinning of rows - strong thickening of the planting is not allowed;
- timely hilling of Rosalind potato bushes;
- if rainy weather is expected, it is advisable to dig up the potato tubers earlier.
After harvesting, it is important to carefully remove the remnants of tops and tubers. It is best to incinerate any leftover debris.
Sometimes out of inexperience or following the advice of inexperienced neighbors, novice summer residents delay digging up potatoes. Such slowness in harvesting early varieties can lead to loss of yield. The optimal time for digging up Rosalind tubers is the first half of August. But more precisely, the period is determined individually and depends on climatic conditions. Indeed, in the event of rainy weather, the harvest is delayed.
The popularity of the Rosalind variety among summer residents is fully justified. Potatoes ripen early, have excellent taste, are moderately starchy and do not fall apart during cooking. Therefore, they are suitable for preparing various dishes.
Ivan Savelyev, Lipetsk
Rosalind potatoes were planted for the first time for testing. Friends shared the seed. I liked the early harvest and its volume (10-15 tubers were dug from the bush). Rosalind potatoes turned out to be tasty - we will plant them in the next seasons. This time they did not experiment with the second landing - the summer is cool. They were afraid of late blight.
Svetlana Nikolaevna Rogova, Belgorod
I have been planting Rosalind for several years in a row. I like that appetizing young potatoes appear on the table early. I select the planting material especially carefully so that the Rosalind potato harvest will please every season. Well, I am not lazy to take care of the beds.
