An early ripe hybrid for the southern regions of the country - tomato “Polonaise f1” and the secrets of increasing its yield

Polonaise f1 tomatoes are an ultra-early ripening hybrid bred by Dutch breeders. It is grown in open ground in the southern regions and in greenhouses in areas with more severe climatic conditions. The culture is easy to care for and resistant to viral diseases.

In this article we will talk about the characteristics of tomatoes, the features of agricultural technology in open and closed ground.

Description of the hybrid

Dutch hybrid Polonaise f1 is a product of selection by Bejo Zaden. Included in the State Register of Selective Achievements of the Russian Federation in 2010. Plant determinant, with a powerful root system, thick stems.

Distinctive features

The table summarizes the main characteristics of the Polonaise hybrid.

Growing seedlings

Polonaise tomatoes are among the ultra-early ripening tomatoes. Sowing of seedlings is carried out in March, two months before transferring to the ground

Preparing seeds and soil for sowing

Hybrid seeds are disinfected in production, so they do not need to be soaked in disinfecting compounds. In addition, the seed material is distinguished by its rapid germination rate.

The soil for sowing seeds is prepared independently from black soil, peat, humus, mixed in equal quantities. Then add 20 g of superphosphate and wood ash for every 10 kg. Ready-made soil mixture for tomatoes from stores is also suitable. It already contains all the necessary nutrients.

The soil is calcined in advance in the microwave, oven, or poured with a strong solution potassium permanganate.

The seedling boxes are filled with moist soil and furrows of 1.5 cm are made. The seeds are laid out at a distance of 2 cm and sprinkled with a layer of soil on top. Water with warm water using a syringe or sprayer and cover with film or glass to create a greenhouse effect.

Shoots appear at an air temperature of +25 °C in 4-5 days. The soil is ventilated daily for 15–20 minutes to prevent mold from appearing.

Seedling care

After the sprouts appear, the boxes are taken to a well-lit place, the film or glass is removed. To prevent seedlings from stretching upward when there is a lack of sunlight, phytolamps are placed nearby.

The seedlings are watered as the top layer of soil dries.

Picking into individual containers made of peat or plastic is done after 2-3 true leaves appear.

Thanks to the efforts of biologists, Polonaise tomato seedlings grow strong without the need for additional fertilizing.

Advice. A week before planting seedlings in the ground, take the containers out into the fresh air to harden for 15–30 minutes.

Tomato cultivation

The early ripening hybrid Polonaise is easy to grow and care for. The culture loves moderate watering and mineral fertilizing. It is characterized by resistance to most nightshade viral diseases.

Landing

Transferring seedlings to open and closed ground begins in May. The timing depends on the growing region. In the southern regions, tomato bushes are planted after the soil warms up to +15 °C (in the second or third decade). In northern latitudes, tomatoes are grown only in greenhouses, so planting is done in early May.

No more than three bushes are placed per 1 m². Holes for seedlings are dug to a depth of 20 cm and disinfected with a hot solution of potassium permanganate. The seedlings are watered abundantly with warm water and rolled along with the earthen lump.

The beds are sprinkled with mulch - peat, sawdust or hay. This allows you to retain moisture in the soil and prevent the growth of weeds.

Care

Five days after planting, the first watering is carried out with settled or rainwater. Then the soil is moistened once a week at the rate of 5 liters of water per 1 m².

Weeding and loosening are carried out without fail after watering.

During the short growing season, tomatoes are fertilized three times:

1. The first portion is nitrogen fertilizers two weeks after planting: 40 g of nitrophoska, 20 chicken manure per 1 liter of water, then increase the volume to 10 liters.
2. The second portion is potassium-phosphorus feeding 10 days after the first: take 10 g of superphosphate, 20 g of chicken manure per 1 liter of water, and bring the volume to 10 liters. Consumption – 5 l/m².
3. The third portion is potassium-phosphorus fertilizer (20 g of superphosphate, 40 g of ash per 10 liters of water) two weeks after the second feeding.Consumption – 5 l/m².

Features of cultivation

A distinctive feature of the Polonaise hybrid is its adaptability to cultivation in the southern regions in the open air. A large amount of green mass protects the fruits from direct sunlight. Plant life processes are less active compared to varieties and hybrids intended for northern regions. At the same time, southern tomatoes are better adapted to changes in weather conditions.

Important! For comparison: “northern” tomatoes are not suitable for growing in open ground in the southern regions due to the small amount of greenery. They quickly burn out under the scorching rays and cannot provide the fruits with the necessary nutrition.

Hybrid Polonaise can be grown in greenhouses in the middle and northern zones. The ovaries on the bushes are formed simultaneously even at low temperatures, which ensures a friendly harvest.

Diseases and pests

Tomatoes are resistant to verticillium fusarium wilt, tobacco mosaic virus.

Thanks to early ripening, there is no time to become infected with late blight, but prevention will not hurt, since the bushes bear fruit until the end of August. To do this, greenhouses are fumigated with sulfur bombs, the soil in the garden is cultivated copper sulfate and mulch with sawdust, pine needles, hay or peat.

The disease can be recognized by brown spots with a gray tint on leaves, stems, fruits, and a white coating on the back of the leaves. The products “Fitosporin”, “Ridomil Gold”, “Quadris”, “Baktofit” will help you quickly get rid of late blight.

To combat spider mites, aphids, and whiteflies, the preparations Fitoverm, Flumite, Epin, and Zircon are used.

In the fight against insects, folk remedies are no less effective:

1. 100 g of dried chamomile flowers are poured into 1 liter of warm water and left for 10 hours. Then bring the volume to 5 liters and add 15 ml of liquid soap. Spray the bushes once a week.
2. Dilute 125 g of liquid soap in 10 liters of water and irrigate the plants once a week.
3. Add 3 kg of ash to 10 liters of hot water and leave for two days. Strain through cheesecloth and add 50 g of grated soap. Treatment is carried out after sunset once every 7 days.
4. Dissolve 10 tbsp in 10 liters of water. l. soda and spray the greens twice a week.
5. Add 1 ml of iodine and 1 liter of water to 200 ml of milk. Used to treat bushes twice a week.

The nuances of growing in open ground and in a greenhouse

Tomatoes in a greenhouse need fresh air and optimal temperature for successful growth.. To ensure comfortable conditions, 2 hours after watering, the doors and vents in the heifer are opened for ventilation for 30–60 minutes. In hot weather, the windows should be constantly open. The optimal temperature during the day is +22 °C, at night +16 °C.

Bushes in greenhouses tie up to the supports, since in such conditions they grow 20–30 cm higher.

Polonaise tomatoes do not require pinching or staking when grown in open ground. The plant has a strong root system and thick stems that can support the weight of the fruit.

Harvesting and Application

The fruits begin to ripen approximately 60-65 days after germination. Tomatoes are used for preparing salads, stews, soups, sauces, adjika, juice, pickling and pickling.

Advantages and disadvantages

Advantages of Polonaise tomatoes:

• amicable maturation;
• formation of ovaries even in cold weather;
• attractive appearance;
• excellent taste;
• 100% seed germination;
• thin skin;

Reviews

Experienced farmers and amateur gardeners share positive reviews about growing the Polonaise hybrid:

Valery, Mineralnye Vody, Stavropol Territory: “These are ideal tomatoes for open ground. The culture pleases with its yield, smooth ripening and ease of care. The tomatoes are almost the same size, with a pleasant taste and bright color.”

Inna, Prikaspiysk, Astrakhan region: “This Dutch hybrid is good for its early ripening and resistance to most diseases. The tomatoes did not even have time to be affected by late blight, although I did not take any preventive measures. Caring for the crop is simple and comes down to moderate watering and fertilizing.”

Nadezhda, Syzran, Samara region: “I’m planting Polonaise tomatoes in the greenhouse. The bushes grow up to 1 m in height, so I tie them to supports. The stems themselves are quite thick and can support the weight of the fruit. There is no need to trim the bushes. The taste of tomatoes is excellent: sweet, with a slight sourness.”
