Watermelon with pink pulp sweet varieties
The pulp of a ripe watermelon can be colored not only in red, but also in pink. There are a number of varieties of watermelons with a lighter internal structure, but in terms of quality characteristics such melons are completely inferior to red ones. Read more about these varieties and the rules for their cultivation, read below.
The considered varieties of watermelons are mostly hybrids. They are more resistant to diseases and pests, and are also able to bring good yields, even on soils with poor nutritional composition.
Early varieties of pink watermelon
Early ripening crops include varieties that mature in 55–75 days. They are characterized by good adaptive abilities, which are manifested by high resistance to temperature extremes, heat and high humidity.
Among these varieties, especially valuable are:
- Prince of Danish F1 - received thanks to the employees of the agricultural company "Zedek". He has been in the State Register since 2013. Fruits ripen in 75 days. Their weight varies from 1.8 to 17 kg, depending on the conditions and region of cultivation. The shape of the fruit is spherical or slightly elongated. The peel is of medium density, painted in dark green color, with slightly pronounced stripes of a lighter shade. The inner contents are painted in a rich pink color, sweet taste. The seed is small. Unlike other early varieties that are not to be stored, the fruits of watermelons Prince Danish are stored for a month after harvesting from the site.
- VNIIOB 2 F1 - One of the first domestic hybrids of watermelon. Bred in 1998. Super-precocious variety - from the emergence of seedlings to ripening takes only 55-60 days. Productivity - high, is 500 kg / ha. The fruits are oval, painted dark green, with spiky stripes of a lighter color. The flesh is pink, sweet, very juicy. It is characterized by high resistance to slightly virulent anthracnose viruses.
The considered varieties are suitable for cultivation in any regions. The fruits have time to ripen and gain a sufficient amount of nutrients and sugar even for a short summer in the northern latitudes. In the southern regions, such crops can be planted 2 times a season.
Mid-season varieties of pink watermelon
Varieties with an average maturity reach maturity at 75–80 days. Among them, Silvia F1 has the most attractive characteristics - it was launched in 2010 by the French company Vilmorin. Fruits ripen in 75 days.
Fruits well in early plantings under film shelters and in open ground. The peel is dense, painted in dark green. Stripes of a lighter shade are pronounced, blurry. The average weight is 13-15 kg. The flesh is bright pink. Taste is excellent.
Another specimen that deserves attention from this series is Big Sugar. Fruits ripen in 80–90 days. The weight of one fetus, on average, is 10 kg. The shape is round or slightly elongated. The inner cavity is pink and raspberry. It has a pronounced watermelon aroma, and excellent taste.
Late varieties of pink watermelon
Late-ripening varieties mature in 90 days or more.
The most outstanding among these varieties are:
- Icarus - the crop ripens in 100 days. The fruits are ellipsoidal. Weight can vary from 3 to 15 kg. The inside is raspberry, juicy, with excellent taste. Fruits are stored for more than 3 months.
- Bush 334 - the fruits reach full maturity in 100 days. Weigh up to 8 kg. The flesh is bright pink, juicy, sugary, without streaks. Harvest after harvest lasts until January. The variety is genetically resistant to anthracnose and fusarium wilt.
Zoned varieties of pink watermelon
All of the above varieties of watermelons can be planted in the south.In the middle lane and in the northern regions, first of all, it is necessary to select strictly zoned crops, since, for example, late varieties in such climatic conditions will not have time to ripen.
Varieties intended for cultivation in cold zones give a stable crop when cultivated in greenhouses, under film shelters and in open ground. Fruits on such specimens are formed small, but they manage to collect a sufficient amount of sugars, which allows them to freely compete with large-fruited southern counterparts.
Did you know? For the New Year, Vietnamese always serve fresh watermelons to the table. The red color of their pulp is considered a symbol of happiness and prosperity next year.
The most attractive varieties from this series are:
- Kai F1 - the variety is characterized by genetic resistance to temperature extremes and lack of light. The highest yield is achieved in greenhouses. When grown in a shelter, the mass reaches 10 kg, in open ground 3-5 kg. They ripen in 70 days. The peel of the fruit is thin, with pronounced stripes. The inside of the fruit is pink, juicy, with a small amount of small seeds.
- Pink Champagne F1 - the fruits of this variety also ripen in 70 days. Their internal cavity is pink-red, very juicy, loose in structure. Weight can vary from 2 to 7 kg.
The sweetest varieties of pink watermelon
In the ranking of the sweetest varieties, the following are especially distinguished:
- Crimson Sweet - matures in 70 days. Plants are very demanding on heat, so they can be grown only in the southern regions. Bright pink flesh, with a rich sweet taste and honey aroma. The weight of one fetus can reach 12 kg.
- Gift of Kholodov - the fruits ripen in 95-110 days. Weigh 4-5 kg. Well stored and tolerate transportation. They are rich in pink pulp with a high sugar content.
Watermelon culture is quite unpretentious in care. To grow a sweet, high-quality fruit, you need to choose the right place for cultivation and the method of planting, depending on the region of cultivation.
Choosing a place for landing, preparing the garden
The place for growing watermelons should be well lit by the sun. The more culture receives light, the higher will be its sweetness at the time of ripening. The soil is well aerated, light, quite nutritious.
Watermelons are best grown and bear fruit on sandstone and loam. But, such soils are not found everywhere. The situation can be corrected by the additional introduction of loosening elements six months before planting - peat, manure, compost, sand.
Did you know? The largest watermelon fruit was grown in Arkansas by Farmer Lloyd Bright in 2005. Its weight was 122 kg.
It is important to consider the location of groundwater when choosing a site. The optimum distance is 2 m to the surface of the melon. Planting should be avoided in lowlands and in flooded areas. The preparation of beds begins in the autumn. At this stage, deep aeration (30 cm) is performed. Then the soil is disinfected with a 3% solution of copper sulfate.
A week later, make, under digging, to a depth of 20 cm per square meter of soil per:
- 10 kg of sand;
- 10 kg of peat;
- 20 kg of fresh manure;
- 20 g of superphosphate.
The next preparatory stage is carried out a month before planting the crop. For each square meter, under digging, to a depth of 30 cm make 20 kg of compost and 600 g of wood ash.
Sowing seeds for seedlings is carried out from mid-March to mid-April, depending on the region of cultivation. First, planting material needs to be prepared - soaked for 20 minutes in a warm solution of potassium permanganate. For 100 ml of water at a temperature of + 30 ° C add 1-2 g of the drug. After soaking, the planting material is thoroughly washed several times under running water.
Wrap in a damp cloth and incubate for about a week in a room with a temperature of + 30 ° C, periodically wetting.As soon as 10% of the total mass of planting material hatch, it can be sown in common containers.
Soil for sowing is prepared by mixing in equal parts:
- soil from the garden.
To this composition is added (20% of the total mass) wood ash. Soil is plentifully moistened. The optimum humidity level is 80%. The seeds are deepened by 0.5–1 cm. The distance between them is 5–7 cm, between the rows 10 cm.
After planting, the containers are covered with transparent polyethylene or glass to create a greenhouse effect. Before emergence, withstand crops in a dark room at a temperature of +27 ... + 30 ° C.
Important! Do not thicken planting watermelons in common containers, otherwise it will be difficult to sprout dives in separate containers later.
In the future, the plants are moistened with a spray gun. At the time of the appearance of 2 real sheets, sprouts dive into different containers. It is best to take peat pots for this.10 days after the dive, nitrogen fertilizer is applied. You can take a liquid mullein. It must be diluted 1:10 with water. Pipette 200 ml under each plant.
In mid-May, when the weather becomes stable and warm (temperature +15 ... + 18 ° С), seedlings are planted in the ground. Pre seedlings need to be hardened. They begin to do this about 1-2 weeks before landing at a permanent place. For this, the daytime and nighttime temperatures are gradually brought to indicators similar to street temperatures.
Then they gradually begin to put plants directly in pots on the street. By the time of transplantation, the sprouts should already be free in open air for 24 hours.
Planting seedlings, depending on the region of cultivation, begin from late April to late May. The most important thing is that the weather is warm outside, the danger of freezing frost is over, and the soil warms up to at least + 10 ° С. Plants are placed at a distance of 50 cm from each other. Between the rows leave a step of 60 cm.
Before planting seedlings, the soil is abundantly watered if there is insufficient natural rainfall. Soil moisture should fluctuate between 70–90%. Holes for planting are dug so large that they fit a peat pot or root system of a seedling (if planting material was purchased “by hand” or grown in plastic containers).
Seedlings are put in the holes, aligned so that the root neck is after it is filled flush with the soil. Next, fall asleep landing pits. The soil around plants and aisles is abundantly mulched with peat mixed with sand and sawdust.
This method is suitable for the northern regions and the central strip. Seeds for planting are prepared as standard: soaked in a solution of potassium permanganate (as when planting on seedlings), washed several times, then dried.
The beds begin to be made in early May so that the soil has time to warm up well. To do this, they dig a trench 30 cm deep, 1 m wide. Manure, preferably horse manure (it generates more heat during decay), sawdust, straw, plant residues, branches are laid in it.
A layer of soil 50 cm high is laid on top of the filled trench. It is best to mix in equal proportions the land from the site, peat, sand. 600 g of wood ash are poured onto a square meter of soil. The bed is covered with agrofibre and wait 1.5–2 weeks until the soil warms up.
Check the heating of the soil in a tactile way. To do this, just touch it with an open area of skin on the wrist or elbow. If the soil is pleasantly warm to the touch, you can sow seeds. Planting material is sown to a depth of 3-5 cm in 2 pieces. Between the holes observe a distance of 40 cm, between rows of 50 cm.
Shelter of agrofibre in the afternoon, when the air temperature reaches + 20 ° C is removed, and with its decrease, returned back. When stable warm weather is established, without changes in night temperatures, you can completely remove the shelter and grow watermelons already in the open.
Landing immediately in open ground
Directly to the open area, watermelon seeds can be planted only in the southern regions. In the northern regions and the central strip, crops simply will not sprout due to lack of heat. Sowing is carried out when the soil at a depth of 3-5 cm warms up to +10 ... + 12 ° С. Planting material is prepared in the same way as in the above methods. The soil is pre-watered so that its moisture content reaches 90%.
After a day, carefully loosen. 2 seeds are sown to a depth of 1-6 cm, depending on their size. The finer the planting material, the less should be the depth of incorporation into the soil. Between the holes leave a distance of 40-50 cm, between rows from 1 to 1.5 m.
Watering and feeding
It is better to moisten the soil in watermelon plantings between rows. The procedure is necessary once a week. There should be about 3-5 liters of water per 1 m², depending on weather conditions. The hotter the climate, the more water is needed. When cloudy weather is established and in rainy periods, watering is not carried out at all. 3 weeks before harvesting, irrigation is stopped completely.
By organizing a drip irrigation system for watermelons, you can greatly facilitate the irrigation of watermelon beds, as well as make the necessary dressings.
Prior to flowering, it is possible to feed the slurry once a month. To 10 liters of water add 1 liter of mullein. Under each plant make a liter of nutrient substance. After flowering, every 10 days, you can irrigate with ash solution. 1 glass of ash is added to 10 liters of water. Under each plant make 1 liter of the finished solution.
Important! After each moistening, the soil between the rows should be thoroughly loosened and mulched with straw. This will make it possible to properly distribute moisture in the soil layers, as well as to keep the fruits and lashes from contact with a moist environment.
Pest and Disease Control
With high humidity, watermelon plantings can be subject to fungal diseases, such as:
- Root rot;
- Leaf spot;
- Downy mildew.
When these ailments appear, the first thing to do is remove all the affected parts from the plants. Then dust the cut points with wood ash. Multiplicity of irrigation should be reduced to a minimum, thoroughly loosen the soil and dust with ash, mulch with peat mixed with sawdust and straw. After that, treat with a 1% solution of Bordeaux fluid. After 10 days, repeat treatment with Bordeaux fluid.
The most dangerous pest for melon is aphid.
At the first signs of its appearance, it is necessary to immediately dust with a mixture of wood ash and tobacco dust on a leaf and soil. Mix the components 1: 1.
To avoid the spread of diseases and pests, you need to perform all agricultural practices on time and monitor the moisture of the soil.
With its increase - to mulch peat. On each plant, after flowering, no more than 3 fruits should be left so as to prevent thickening of the plantings.
Useful qualities of watermelon
The composition of watermelon pulp includes mineral salts, vitamins of group B, PP, C, folic acid and carotene.
Due to the harmonious combination of all elements, the use of the fruits of this plant favorably affects the whole organism as a whole:
- removes excess fluid, cholesterol and toxins, exerting a diuretic effect;
- improves liver function;
- increases the body's overall resistance to negative environmental factors;
- stimulates the production of blood cells;
- normalizes blood pressure.
How to understand when buying that a watermelon is not "overfed" with nitrates
Not every fruit of the plant in question will benefit the body.Copies grown on nitrate fertilizers can cause irreparable damage to health, even death, so you need to know how to choose the right watermelon in the market.
Important! Do not buy watermelons near highways. Even quality products that have lain on the street for several days, absorb exhaust fumes. Using such melons can be difficult to poison.
When buying a watermelon, you need to follow these rules:
- Do not make a purchase earlier than the beginning of August - even the earliest varieties do not have time to ripen naturally in this way.
- From the proposed assortment of fruits of one variety, you need to choose an average in size.
- The peel of the fetus should be dense, without flaws. A lighter barrel of white or yellow flowers (the area that came into contact with the soil during the ripening period) should occupy no more than 10 cm. If this site is larger, the culture was grown under adverse conditions.
- Peduncle - it must be available if it is torn off, so they are trying to hide the quality of the products. According to the structure of a high-quality, ripe watermelon, the peduncle should be moderately dry, with a yellowish tinge.
- The condition of the pulp is the most important criterion that will help determine the presence or absence of nitrates. The inner color should be saturated - a too pale shade and white tone of the seeds indicates that the fetus has ripened with nitrate fertilizers or an injection that helps stain the pulp. The surface of the pulp on the slice of a quality product will be granular - the nitrate-containing fruits on the slice will be completely smooth, shiny. The veins should be painted in a slightly pinkish color - white and yellow indicate a large amount of nitrates.
Watermelons with pink pulp are not inferior in quality to red-fruited varieties, and sometimes even surpass them in sweetness. They are unpretentious in cultivation and are more resistant to adverse weather conditions.
