An extended fruiting period allows you to increase the yield of tomatoes when grown in greenhouses and film shelters.
According to the characteristics, the tomato variety Sultan F1 is drought-resistant. The crop bears fruit even on soils with low fertility levels.
The plant is resistant to most specific tomato diseases.
Advantages and disadvantages
Based on the reviews and photos of those who planted the Sultan tomato variety, it is easy to determine the advantages of the variety:
- unpretentiousness;
- high productivity;
- long fruiting period;
- excellent taste characteristics;
- disease resistance;
- good transport tolerance;
- high keeping quality.
Vegetable growers consider the inability to collect seeds of the Sultan tomato variety as a disadvantage.
Growing rules
Tomatoes of the Sultan variety are grown in seedlings. In southern regions with long periods of high air temperatures, you can get a tomato crop by directly sowing seeds in the ground.
Planting seeds for seedlings
The seeds of the Sultan F1 hybrid are prepared and tested for germination. Therefore, pre-soaking in water or seed germination accelerators is not recommended.
By the time tomatoes are planted in the ground, the seedlings should be 55-60 days old.
To obtain high-quality planting material, the soil should be light and breathable. It is recommended to use a soil mixture of equal parts of turf soil, river sand and peat with a neutral acidity level.
Low containers with holes in the bottom are suitable for germinating tomato seeds. To do this you need:
- Fill the box halfway with soil.
- Lightly compact the soil and water with warm water.
- Place the seeds at a distance of about a centimeter from each other.
- Sprinkle with a layer of soil of at least 1 cm.
- Cover with film.
- Germinate at a temperature not lower than 22 - 24 degrees.
When the first shoots appear, remove the film and place the seedlings in a bright place.
Tomatoes easily tolerate transplantation. You can pick up plants in separate glasses or boxes of several pieces.
Picking seedlings is carried out when two true leaves develop in highly moist soil.
After transplanting, it is recommended to place containers with tomatoes for 2 - 3 days away from direct sunlight.
Before planting tomatoes in a permanent place, it is necessary to feed the plants at least twice with complex fertilizer.
To improve the development of the root system, you can use special root-forming fertilizers “Kornevin”, “Zircon” or any other growth stimulants. Top dressing helps the formation of a powerful root system and accelerates the development of healthy seedlings.
It is necessary to water the seedlings regularly with water at room temperature, avoiding drying out the earthen ball.
Before planting in the ground or greenhouse, plants should be hardened off. To do this, the temperature in the room is gradually reduced by 1 - 2 degrees.If the weather permits, the boxes with seedlings can be taken out into the open air. The temperature should not be lower than 18 degrees. Hardening is carried out by uniformly increasing the period of exposure to low temperatures.
Transplanting seedlings
Tomato seedlings can be planted in open ground only after the threat of spring frosts has passed. When the temperature drops below 10 degrees, you need to use film shelters.
Compact tomato bushes of the Sultan variety are planted in a greenhouse according to the following scheme: 35 - 40 cm between bushes and about 50 cm between rows. Planting can be done in a checkerboard pattern.
The soil must be loosened to a depth of 30 - 40 cm. Compost or rotted manure should be poured into the holes prepared according to the markings at the rate of 0.5 liters for each plant.
It is important to water the seedlings and holes prepared for planting generously with water.
Landing algorithm:
- Remove the seedling from the seedling container.
- Shorten the main root by a third.
- Install into the hole.
- Sprinkle with soil to a stem height of 10 - 12 cm.
- Compact the soil around the plant.
It is advisable to plant tomatoes in the evening or in cloudy weather.
Aftercare
Throughout the growing season of tomatoes, it is necessary to monitor soil moisture. Regular watering, alternating with loosening the soil around the bushes, will help speed up flowering and development of ovaries.
10 days after planting the seedlings in a permanent place, it is necessary to fertilize with a complex fertilizer containing phosphorus, potassium and microelements. To form a bush, nitrogen is also required to grow green mass. It is recommended to use nitroammophoska or calcium nitrate.The method of application of the fertilizer and dosage are indicated on the product packaging.
Bushes of the Sultan F1 tomato variety do not need to be tied up. Low-growing tomatoes with thick, elastic stems can easily withstand the weight of the fruit.
Experts advise forming a bush into 2 trunks. But, according to reviews of the Sultan F1 tomato, with a sufficient level of soil fertility and proper care, you can increase the yield by leaving an additional stepson.
Pruning should be carried out regularly, preventing the regrowth of side shoots. Removing large stepsons threatens the plant with stress, which negatively affects development and yield.
For the second and third feeding, which can be done at intervals of 2 weeks during fruit set, it is recommended to use a complex of minerals with a high content of potassium and phosphorus. Nitrogen fertilizers should be excluded. When there is an excess of them, tomatoes begin to intensively increase their green mass to the detriment of the fruits.
If a large number of fruits develop at the same time, some of the unripe tomatoes must be removed from the bush. Tomatoes of the Sultan variety, according to reviews, can ripen in a dark place, placed in cardboard boxes.
To protect against fungal diseases in the greenhouse, it is necessary to provide stable ventilation for tomatoes. Sultan tomatoes tolerate drought more easily than excessive moisture.To prevent diseases, bushes can be treated with a solution of Bordeaux mixture, Quadris, Acrobat or Fitosporin. If the standards and processing times are observed, the drugs are safe.
To protect plants from whiteflies, mites, aphids and the Colorado potato beetle, it is recommended to use standard chemical and biological agents.
Conclusion
Due to its unpretentiousness, the Sultan F1 tomato is suitable for growing by novice vegetable growers. A fairly high yield of tomatoes of this variety is obtained even under unfavorable weather conditions. A thick, tasty juice is made from the bright, sweetish-sour fruits. Smooth tomatoes in marinade jars look great.
