The agricultural company Monsanto Holland BV produced the CB 4097 F1 cucumber with the Russian consumer in mind, since its characteristics ideally correspond to the weather conditions of the country. This variety was included in the state register of the Russian Federation in 2013. According to the description, these cucumbers can grow and bear fruit in abundance both in greenhouses and in open ground. Greenhouses can be completely different - from polycarbonate, film or glass - since the leaves of these cucumbers are not afraid of sunburn.
Description of the variety
This is a parthenocarpic hybrid of early ripening. It does not require insects for pollination, which means the bushes can grow well indoors. The only requirement is sufficient lighting, since with the lack of light the yield and taste of the fruit will deteriorate; the flowers are predominantly female. The plant itself is:
- compact;
- branched;
- medium thickness.
The root system is powerful and well developed. This should be taken into account, and if the SV4097 cucumber is planted through seedlings, then bulk containers should be taken. One node usually has 2 or 3 ovaries. If the region in which the variety grows is warm, then there may be more ovaries on the site - up to 4 pieces. The color of the plants is large and does not fall off. The leaves are rich dark green, slightly wavy and quite large.
Description of fruits 4097 cucumbers:
- cucumbers of the CB 4097 F1 variety are distinguished by their proportional oval shape;
- the surface is covered with frequent medium-sized tubercles;
- weight can reach 90-100 grams;
- length - 12-13 cm;
- diameter - 3-3.5 cm;
- cucumber skin is a rich dark green color with barely noticeable streaks of light;
- white spines;
- partial pubescence occurs on the surface.
According to reviews from gardeners, the average yield ranges from 8 to 10 kg per square meter. But with proper care, you can increase this figure to 15 kg per square meter.
Characteristics of the variety
Cucumbers sv4097cv have a proportional oval shape. The surface of the fruit is covered with several medium-sized tubercles. The spines are white. The skin is dark green, rich in tone, with almost invisible light stripes. The surface of cucumbers has a slight fluff. Cucumber parameters:
- diameter - 3 cm;
- weight - 100 g;
- length - 12.5 cm.
Thanks to these characteristics, the popularity of CB 4097 cucumbers can be explained. Reviews help determine the volume of the harvest. Gardeners say that on average you can harvest about 9 kg of cucumbers from 1 m². With proper care, this figure increases to 15 kg per 1 m².
Features of cultivation
St 4097 cucumber is grown by seedlings and without seedlings.
Sowing cucumber seeds for seedlings is carried out approximately a month before planting on the site:
- Cucumber seeds must first be soaked and germinated - this will speed up the emergence of seedlings.
- Cucumber seedlings are planted directly in open ground when the soil warms up enough (approximately at the end of May in central Russia, at the beginning of May in central Europe).
- With the seedless method, sowing of swollen or sprouted cucumber seeds is carried out in soil whose temperature in the upper layer is not lower than 13-15 degrees, otherwise the seeds simply decompose.
- The sowing depth of cucumber seeds is about 2 cm, the density is 5-7 plants per square meter.
The soil for cucumbers should be moderately loose, retains moisture well and is very fertile. Since the root system of the cucumber is small, it is very convenient to grow cucumbers by bringing organic matter locally - into planting holes or trenches:
- Dig a hole or trench to a depth of about 40 cm.
- Pour a layer of organic matter, mix it with the soil, and top it with the now clean soil on which the cucumbers are planted.
- When decomposed, organic matter releases a lot of heat, which accelerates the growth and development of plants, and then serves as an excellent feed for almost the entire season.
Expert opinion
Filatov Ivan Yurievich, private farmer for more than 30 years
The place for growing cucumbers should be well lit by the sun (partial shade is allowed) and protected from the wind. In particular, when planting ridges outdoors, corn can be used as a "living barrier" by planting two lines on the sides of the cucumbers, leaving the southern side open.
The optimal temperature for the normal development of cucumbers ranges from 23 to 30 degrees:
- Air temperatures below 15 degrees lead to inhibition and cessation of plant growth at any stage of development.
- Frosts are destructive (especially for young, immature plants), and the drop in temperature inhibits growth. Therefore, in Northern Europe and central Russia, cucumbers are often grown under film covers, at least in the first half of summer.
Preparing seedlings
As it grows, “SV 4097 CV f1” acquires a powerful root system, so for planting it is necessary to provide a larger container. Before planting, the seeds are sorted, after which they are heated for a month next to heating devices. Then they need to be hardened by wrapping them in cloth and immersing them in warm water for 1 hour. Next, without unfolding, the seeds are placed in a cold place for a day, at a temperature of +1 to +5 °C.
At the beginning of May, the prepared seed material is planted in a container with soil, at a distance of 15-20 cm from each other. A better option would be to plant in separate peat pots; in this case, at the stage of planting in the ground, there is no need to remove the shoots from the container, that is, it is allowed to plant directly in pots. In the future, they will supply the growing plant and its roots with useful microelements.
The seedlings are placed on a flat surface with good lighting. A window sill or table with a lamp pointed at it is suitable for this. But in the first case, it is recommended to put foam plastic or a piece of insulation cut to size under the container with seedlings. The fact is that a cold window sill will give up its temperature to the soil, which is why the shoots may emerge much later or emerge sick.
Watering is carried out daily in the morning, with warm, settled water, from the tap. After mass germination, irrigation is stopped for 2-3 days to strengthen the shoot trunks, then continued as usual. Humidity plays a big role in the formation of seedlings, so if there are heating devices in the room, it is advisable to install an air humidifier or a bowl of water next to the plants.
Important!
Watered soil should have the consistency of a wet, but not sticky, lump. If this happens, it is advisable to stop watering for a day.
Care
Many people are interested in questions about the features of caring for plants, the answers to which will be found in the reviews. St. 4097 color cucumber is simple, but requires attention and timely implementation of certain procedures. For example, you need to promptly remove yellowed leaves:
- If the plant has grown more than 18 leaves, then after harvesting at 6-9 nodes the first 4 leaves should be cut off.
- All other leaves should be removed gradually as they turn yellow. It is important to follow the basic rule: the plant must have at least 18 leaves.
- Remember that when working with leaves, you cannot touch the petiole. Only the leaf blade needs to be removed. This helps reduce the risk of disease on the main stem.
- Stepchildren also need to be removed after fruiting of CB 4097 cucumbers. Expert comments recommend placing a small part of the stem on soil covered with film. Some gardeners plant stems on special metal supports.
Good lighting and high temperature have a beneficial effect on plant growth. And vice versa, their deficiency affects the length of the green, it is small. The vegetative growth of the plant balances its development. For this purpose, experts recommend reducing the average daily temperature. This reduces the difference between night and day ambient temperatures.
Supplemental foliar feeding can improve fruit quality, shelf life and tolerance. It is recommended to fertilize 2 times a week. In turn, the fertilizer is used with trace elements and calcium nitrate.
Advantages and disadvantages
The hybrid variety SV 4097 CV has taken root well in our country. Today it is widespread in all its regions. Vegetables are grown in dachas, small farms and large agricultural firms.
The advantages of cucumbers include:
- Early maturation. Fully formed greens are obtained within 38-46 days after the first shoots appear.
- Low temperature resistance. Plants easily tolerate sudden and prolonged cold snaps and do not lose vitality due to cool night fogs.
- Immunity to most diseases affecting garden crops. The hybrid variety is resistant to brown spot, crown mold, cucumber mosaic virus and powdery mildew.
- Good keeping quality. The crop tolerates transportation well even on bad roads. In a dark, cold and well-ventilated basement with a low moisture content, the fruits are stored for up to six months without loss of commercial quality.
- Independence from timely removal. After ripening, cucumbers do not turn yellow, remaining fresh, elastic and tasty. When falling on the ground, they do not suffer from impacts due to their elasticity and strong peel.
- Decent yield. By growing this variety, farmers are sure that they will get their kilograms from each bush. The resistance of plants to the influence of external conditions and ease of care contribute to the fact that more and more gardeners are choosing them.
- Presentable appearance and excellent taste. Cucumbers immediately attract attention on the counter. Farmers successfully sell surplus crops in markets and procurement offices.
Farmers did not find any significant deficiencies.
Diseases and pests
The likelihood of being affected by the disease increases with high environmental humidity. The way out of this situation is to reduce air humidity. The maximum score should not exceed 80%. Regular levels of air supply and relative humidity also have a positive effect on crop quality. These recommendations are contained in reviews by agronomists.
Do you regularly ventilate the greenhouse?
Not really
Cucumber CB 4097 shows high resistance to cucumber mosaic virus and Cladosporium. This means that the plant does not respond to pathogens. Intermediate resistance appears in powdery mildew. In other words, this variety can limit the development of certain pathogens. Compared to other susceptible varieties, cucumber CB 4097 F1 suffers less damage.
To prevent the destruction of the plant by powdery mildew, it is necessary to regularly fertilize the cucumber and monitor its development.
