To get fresh vegetables as quickly as possible, growers select the earliest varieties that have the shortest period from sowing to the first harvest. The Harmonist cucumber, an early maturing hybrid intended for indoor cultivation, is best suited to this goal.
History of appearance
Cucumbers Harmonist F1 (Cucumis sativus L) - the result of the work of Russian breeders (Gavrish S., Portyankin A., Shamshina A., Shevku). The variety was obtained in the Gavrish seed company, in 2008 it was entered in the State Register and recommended for cultivation in greenhouses in most regions of the country.
Cucumbers Harmonist F1 - hybrid of the first generation
Description of cucumbers Harmonist F1
Shoots of cucumbers variety Harmonist F1 are rough, creeping, form a bush with moderate lateral branching. The length of the stems of the plant is 160-200 cm. In the presence of a vertical support, they cling to it with antennae located at the tops. The leaves are bright green, medium in size, heart-shaped, five-lobed. The flowers are yellow, feminine. Up to 4-5 ovaries develop in one sinus. Fruits of cucumbers variety Harmonist F1 are cylindrical in shape, with small tubercles. At the stage of technical ripeness, their length is 10-13 cm, diameter is 3.5 cm, average weight is about 100 g. The skin is slightly pubescent, dark green, the tips are lighter. Small whitish spots or blurred streaks are acceptable. Fruits of a dense structure, without voids.
The flesh of cucumbers of the Harmonist F1 variety of excellent taste without bitterness, with a characteristic aroma
Characteristics of cucumbers Harmonist
The variety is parthenocarpic, i.e. self-pollinating. The type of flowering is female, already during the budding period, ovaries are visible, appearing in the axils. The branching level is low. The plant is hygrophilous, it does not tolerate drought. With a lack of moisture, it withers, stops growing. With a prolonged absence of watering, the greens turn yellow and dry out. Cucumbers Harmonist F1 are sensitive to a drop in temperature, develop slowly if the soil is not warmed up enough.
Yield
The yield depends on the stage at which the fruits of the Harmonist F1 variety are removed. When harvesting cucumbers in technical ripeness, it is 13 kg cm2, in the phase of pickles - 5 kg. The final result depends on the correct preparation of the soil, the absence of thickening of the plantings, the regularity of watering, loosening, and airing the greenhouse. It is equally important to carry out top dressing and preventive measures to protect against diseases and pests on time.
Ripening and flowering terms
Harmonist F1 is a partenocarpic hybrid with female flowers that do not require pollination. Cucumber buds form after the foliage and roots of the plant slow down their growth. The variety is early maturing. Flowering occurs 30 days after germination and ovaries are formed. The first buds bloom on the main stem, gradually passing to the lateral ones of the first and second order. The fruits ripen two weeks after the beginning of flowering.
Subject to agricultural technology, the fruiting of the plant lasts from 30 to 60 days.
Fruits of cucumbers variety Harmonist F1 do not form seeds
Disease and pest resistance
The hybrid is immune to most diseases, but if agricultural technology is violated, the likelihood of cucumbers being damaged by powdery mildew, cladosporiosis, and root rot increases.
Cladosporium
Young plants most often suffer from the fungus. It gets on the foliage of the Harmonist cucumbers together with water, garden tools, shoes, insects. A net of red spots appears on the bushes, which gradually become wet, necrosis develops, and the plant dies. To destroy the fungus at the first signs of the disease, spraying with Bordeaux liquid is carried out.
For the prevention of cladosporium disease, Harmonist F1 cucumbers are sprayed with a solution of copper oxychloride (0.4%)
Powdery mildew
The disease can be detected by a white bloom on the back of the leaf, later whitish spots grow on the outside. Then the leaf plates darken, curl and dry out. As a treatment, spraying with soda solution (0.4%) and Fitosporin is used.
The fruits of Harmonist cucumbers, affected by powdery mildew, are not juicy, have a bitter taste
Root rot
Dark spots appear on the roots of plants, the stem gradually becomes thinner, dries up, withers and dies. The cause of the disease is a violation of agricultural technology and irrigation regime. The disease spreads very quickly, therefore, at the first sign, the affected bushes are removed and burned, and the soil is treated with a solution of bleach (150 g per 1 m2).
Watering cucumbers of the Harmonist F1 variety is reduced to a minimum when the first symptoms of root rot appear
Insect pests are no less dangerous for plants.
Spider mite
Ticks are difficult to spot as they are less than 1 mm in size. The pests are given out by the cobweb enveloping the foliage. If the treatment with acaricides (Keltan, Phosphamide) or biological products (Bitoxibacillin) is not carried out in time, the Harmonist cucumbers will die.
The mite sucks the sap from the leaves and weakens the entire plant.
Aphid
Pests settle in colonies on the back of the foliage. Hordes of insects infect flowers and ovaries, suck sap and dehydrate plants. To destroy pests, biological products are used (Aktofit, Fitoverm), and in advanced cases - insecticides.
The peak of aphid activity on cucumbers is the middle of summer.
Advantages and disadvantages
It will take only a month and a half to get the first harvest of cucumbers Harmonist F1. The early maturity of the variety is not its only advantage. Fruiting of the Harmonist hybrid is abundant and long.
Pros:
- self-pollination of the variety;
- disease resistance;
- excellent taste without bitterness;
- good transportability;
- high productivity;
- versatility of application.
The variety has practically no minuses. The disadvantages of the Harmonist F1 hybrid include the inability to collect and use seeds.
Planting cucumbers Harmonist
Cucumbers Harmonist F1 can be grown by sowing seeds or using seedlings. In any case, they create a shelter - temporary or permanent. A greenhouse or greenhouse helps to obtain optimal conditions for plants, shorten the ripening period of the crop, and protect against adverse weather.
Sowing in open ground
When choosing a place for planting cucumbers of the Harmonist variety, they prefer the southern side of the site, protected from drafts and northern winds. It should not be waterlogged, shading is unacceptable. Ideal precursors for cucumbers are legumes, wheat, rye, tomatoes or cabbage. To sow seeds in open ground, it is necessary to prepare the soil. It is dug up, weeds are removed, disinfected, compost, wood ash, potassium sulfate are added. Ridges of medium height should be formed in advance and covered with a film to warm the soil.
The seeds of cucumbers Harmonist F1 are calibrated, disinfected in a solution of potassium permanganate, hardened, bubbled. Sowing is carried out in grooves 3-4 cm deep.They are laid out with an interval of 20-30 cm and covered with a layer of soil 2 cm thick.A shelter is made above the ridge of arcs, film or non-woven material.
Sowing dates are calculated so that seedlings appear after the threat of frost has passed
Seedling method
Cultivation of cucumbers Harmonist F1 from seedlings significantly accelerates their growth, development, and fruit formation. Sowing of seeds begins in the third decade of April. Containers, plastic or peat glasses are used as containers for seedlings. They operate according to the algorithm:
- The containers are filled with the finished soil mixture by two-thirds of the volume.
- Pour with warm, settled water.
- In the center, make a hole 1.5 cm deep.
- Place one seed at the bottom.
- Fall asleep with soil.
- Cover with foil and transfer to a warm (+ 27 ° C) place.
After 3-4 days, the seeds of cucumbers Harmonist F1 give the first shoots. The shelter is removed, and the containers are transferred to a cooler (+18 ⁰C) and well-lit place. In the phase of 2-3 true leaves, the seedlings are transplanted into the greenhouse by the transfer method or together with a peat glass. Plants are placed at a distance of 50 cm from each other, watered and create a support to which the Harmonist F1 cucumbers will be tied as they grow.
It takes 25-30 days to grow seedlings of the Harmonist F1 variety
Rules for caring for cucumbers Harmonist
The Harmonist variety is very demanding on moisture. It is carried out twice a week, and in hot weather - every other day. The water should be warm and settled.
During the season, they are fed several times:
- In the flowering phase - infusion of chicken manure, diluted in a ratio of 1:20.
- During fruiting - liquid manure (1:20).
- To increase yields - ammonium nitrate (15 g) and double superphosphate (20 g).
For uniform illumination of cucumbers, they are periodically tied to a trellis. So that the bushes do not thicken, they carry out pinching - 2-3 side shoots are removed. At a height of 1.5 m, the tops of the plants are pinched.
Cucumbers of the Harmonist variety are watered in the evening, and in the morning they loosen the soil, remove weeds, mulch the soil surface
Conclusion
Cucumber Harmonist F1 - one of the best options for growing indoors. When all the rules of agricultural technology are followed, fruiting occurs early and lasts until autumn. The variety is not capricious, responds well to care, so even novice gardeners can get an impressive harvest of vegetables.
