In what soil does the Rosemary tomato yield the highest yield and what else affects it?

Tomatoes Rosemary f1 - an early ripe hybrid with high yields, unrivaled taste and aroma, resistant to viral diseases of nightshade and late blight.

The fruits contain an increased amount of beta-carotene and are suitable for dietary and baby food. In the article we will talk about the advantages and disadvantages of a hybrid, the nuances of cultivation in a greenhouse and in a vegetable garden under a film cover.

History of creation

The hybrid Rosemary (more correctly called Rosamarin f1) was bred by biologists of the Scientific Research Institute of Vegetable Breeding and Agrofirm Gavrish in 2003.

Description of the hybrid

The table contains the distinctive features of the tomato.

Reference. Rosemary fruit pulp contains twice as much vitamin A as other tomatoes.

Pros and cons

The benefits of culture:

• large fruits;
• excellent taste and aroma;
• evenness of fruits in size;
• strong trunk structure;
• resistance to nightshade diseases and insect attacks;
• high vitamin A content;
• suitable for diet food.

Disadvantages:

• low level of keeping quality and transportation;
• thin skin cracks when moisture is deficient;
• tomatoes are not suitable for pickling and salting;
• requires a film shelter in the open field;
• tall bushes need pinching and garter.

Tomato agricultural technology

Growing rules are standard, as for everyone indeterminate hybrids:

• tomatoes are grown through seedlings;
• landing is carried out in well-heated soil;
• bushes are stepson and tied to supports or trellis;
• provide moderate watering with warm water;
• the soil is periodically loosened or covered with mulch;
• feeding with complex fertilizers.

Seed preparation

The seeds of the hybrid do not require additional disinfection, since they are processed in production. To increase the percentage of germination, the grains are soaked in ready-made growth stimulants - "Epin", "Immunocytofit", "Zircon" or use natural remedies:

1. The juicy leaves of aloe are kept in the refrigerator for 24 hours, then the juice is squeezed out through cheesecloth and diluted with water 1: 1. The seeds are soaked in the solution for 4-6 hours. In addition to stimulating germination, aloe improves plant immunity.
2. A handful of onion skins and 1 tsp. wood ash pour 500 ml of boiling water and leave for three days. Strain and soak the seeds in the infusion for 2-4 hours before use.
3. Dissolve 1 tsp in a glass of warm water. natural honey. Soak seeds for 5-6 hours.

Important! Before processing in stimulants, the seed is soaked in thawed water at room temperature until it swells.

The soil

A mixture of turf, peat and humus in a 1: 1: 1 ratio is ideal for growing seedlings.

Before use, the substrate is calcined in an oven at a temperature of 100-110 ° C or steamed in a double boiler for an hour.

Sowing

Sowing is done in the last week of March or early April. The seedling boxes are filled with a damp substrate and the seeds are placed in furrows 1.5 cm deep at a distance of 2 cm. Top them covered with a 1 cm layer of soil and covered with glass or foil.

The boxes are taken to a dark, warm place. The optimum room temperature is not lower than +24 ° С.

Seedling care

The film or glass is removed after the sprouts appear. The boxes are taken out to a sunny place. Seedlings are watered as needed, after the top layer of the earth has dried.

To prevent the development of the fungus, the seedlings are taken out into fresh air for 20-30 minutes.

After the appearance of 3-4 true leaves, the sprouts are planted in separate containers made of peat or plastic, carefully pinching off the tip of the root.

Landing in the ground

The transfer of mature seedlings begins 60-65 days after germination, starting in mid-May. The site is chosen on the sunny side, since productivity decreases in the shade. The best predecessors of tomatoes are radishes, dill, parsley, and cabbage.

The culture prefers a light nutritious soil with neutral acidity - pH 7. The dense soil is loosened with river sand or peat. The soil is brought to normal with wood ash or chalk:

• sour - 400-500 g per 1 m²;
• medium sour - 200-300 kg 1 m²;
• slightly sour - 200 g per 1 m².

Dig holes for seedlings at a depth of 15-20 cm and fill with a strong solution of potassium permanganate, add 1 tbsp. l. superphosphate. The seedlings are watered abundantly with warm water and transferred together with an earthen clod from a plastic container or planted directly in a peat glass.

There are no more than three bushes per 1 m². Landing scheme - 40x60 cm.

Care

The culture is not demanding to care for, it prefers moderate watering and fertilizing with mineral compounds.

Care rules:

1. The humidity level in the greenhouse should not exceed 70%.
2. It is undesirable to overflow the soil, and at the same time, allow it to dry out. The best solution to the watering issue is to install a drip system.
3. For glaze use rain or settled water.
4. Bushes stepchildren once every 10 days and form into two stems.
5. At the end of the growing season, pinch the top. The plant will stop growing, and all the energy will go to the tomatoes.
6. Perform garter not only stems, but also flower brushes, which can break under the weight of the fruit.
7. After watering, the soil is loosened to prevent the formation of a hard crust.

Advice... Cover the soil with mulch (sawdust, straw, hay, synthetic black agrofibre) to eliminate routine weeding and loosening, retain moisture, and prevent fungal infestation.

Top dressing

Tomatoes are fed at least three times during the growing season according to the scheme:

1. The first organic feeding 14 days after planting - chicken droppings with the addition of water in a ratio of 1:10 or ready-made products: "Gumisol", "Veromistin".
2. The second top dressing 14 days after the first - with a complex fertilizer "Solution" with calcium, manganese, potassium and phosphorus in the composition. For 1 bush - 2 liters of solution.
3. The third subcortex during the period of fruit emergence "Solution" 2.5-3 liters for each bush.

Growing difficulties

Tomatoes are sensitive to both deficiency and excess of mineral components. By the appearance of the bushes, it is easy to determine the state of the plant:

1. Gains green mass, but does not bloom - an excess of nitrogen in the soil. Wood ash will help reduce its amount.
2. Bushes stretch upwards, leaves turn pale - nitrogen deficiency.
3. Leaves acquire a purple hue with a deficiency of phosphorus, fall off - with an excess of it.
4. The green mass becomes dull when there is an excess of potassium and dries up when it is deficient.

The nuances of growing in open and closed ground

The technology for growing a hybrid in a greenhouse and in a garden is the same. Indoors, they monitor the appearance of the bushes and react in time to signs of deficiency or surplus of minerals. Errors in care lead to infection with fungal spores.

In the south of the country, the culture is grown in unprotected soil, but the first time after planting is covered with a film, waiting for the complete rooting of seedlings. The bushes are also formed into two stems and tied to a trellis or stakes.

Prevention of diseases and pests

The Rosemary hybrid is genetically protected from infection with viral diseases of the nightshade (verticellosis, fusarium, tomato mosaic). Seed producers claim that the culture is not afraid of late blight (brown spots, whitish bloom on the leaves and trunks, the ugly shape of the fruit).

However, prevention will not be superfluous:

• soil cultivation with copper sulfate;
• disinfection of greenhouses with sulfur checkers;
• removal of the lower yellowed leaves;
• control of the moisture level in the greenhouse;
• moderate watering at the root;
• soil covering with mulch.

The main problem that gardeners face when cultivating a tomato is leaf curling. If you do not take measures in time, you can be left without a crop. The reason for this condition lies in the overabundance of organic fertilizers in the soil, the air temperature in the greenhouse is above +32 ° C, and copper deficiency.

Ways to solve the problem:

• the introduction of phosphorus-potassium fertilizers;
• treatment with Agrophon containing copper;
• airing greenhouses to normalize the temperature regime.

The hybrid is often attacked by a bear, Colorado potato beetle, whitefly, aphid, caterpillars. Modern safe insecticides help to fight pests: "Thunder", "Fitoverm", "Iskra", "Force", "Epin", "Confidor", "Komandor".

Harvest application

The first fruits appear approximately 112 days after germination. Tomatoes are removed carefully, twisting them out of the stalk, being careful not to damage the thin skin. The shelf life is minimal, so they try to use them immediately.

The fruits are eaten fresh. Due to the delicate skin, tomatoes are completely unsuitable for pickles and whole salting.

Too soft tomatoes are used for adjika, lecho, sauce, juice, tomato paste.

Reviews

The impressions of growing this large-fruited hybrid among gardeners are mostly positive.

Elena, Kstovo: “Before deciding to grow rosemary tomatoes, I read the reviews of those who planted. Inspired, I acquired seeds. The characteristics and descriptions of tomatoes on the package are true. The seedlings grew strong, they did not feed them with anything. Moved to the greenhouse in early June. From fertilizers, I applied chicken manure and potassium-phosphorus fertilizers. Watered with warm water once a week under a bush. In a drought, the frequency increased to two irrigations. The harvest was a success, I didn’t eat more delicious tomatoes ”.

Yaroslav, Borisoglebsk: “Last year I tried to grow Rosemary in a vegetable garden, before that I planted it in a greenhouse. Bushes are strong, with a thick stem, tall. Tied to wooden stakes, covered with foil in extreme heat. I did not notice any special problems in leaving. The main thing is to water and feed in moderation. The tomatoes have grown large, fleshy and very sweet. "

Conclusion

Hybrid Rosemary or Rosamarin f1 (original name) is an interesting find for tomato lovers with pink thin skin and aromatic, sweet pulp. The plant is reliably protected from the main "tomato" diseases (verticellosis, fusarium, tomato mosaic, late blight), suitable for growing in any type of soil. A prerequisite for successful cultivation in the garden is the organization of a temporary film shelter.

Tomatoes love sun, moderate watering, organic and mineral fertilizing. The fruits grow large and fleshy. One thing is upsetting - they cannot be stored for a long time because of their thin skin.
