It's February, which means that sowing of some crops begins. It's time to discuss the intricacies of sowing and growing healthy seedlings. Today we'll talk about tomatoes. You can speed up the harvest by growing seedlings in greenhouses. This process is laborious and responsible. It is necessary to properly prepare the soil for seedlings, monitor the temperature, light, and humidity. It is very important to know the original place of growth of a given culture, its biological characteristics. This will avoid mistakes and get healthy and strong seedlings.

In the middle lane, ripe tomato fruits can only be obtained through the seedling method of growing, since the period from germination to the end of fruit ripening is 85-120 days.

Seeds of indeterminate (tall) varieties and hybrids are sown from March 20-25, determinant (with limited growth) from March 25 to April 10.

In open ground, 40-50-day seedlings are planted, in the south, 30-day ones. The optimum temperature for seed germination is 24-26 ° C.

When loops appear, it is necessary to remove the covering film and expose the boxes or cassettes to the light. After the cotyledons open, the temperature is lowered to 18-20 ° C during the day and to 16 ° C at night. High illumination and relatively low night temperatures lead to early formation of the first peduncles, which, in turn, contributes to a decrease in the number of leaves to the first inflorescence and an increase in the number of flowers in inflorescences, and also prevents seedlings from stretching.

After 7-10 days, the temperature of growing seedlings is increased during the day in sunny weather to 20-22 ° C, in cloudy weather to 18-19 ° C, at night the temperature is 17-18 ° C.

When sowing in a school / seedling boxes / the optimal picking time is when 1-2 true leaves appear / after 10-14 days. after shoots /.

The composition of the land for picking: 7 parts - low-lying decomposed peat, 2 parts of humus + 1 part - sod land or 5 parts of sawdust + 3 parts of peat + 2 parts of land.

Watering and feeding of seedlings is carried out by micro sprinkling or saturating the cassette from below from 8 to 10 or from 15 to 17 hours. An important point - plants should not leave wet during the night.

During the period of growing seedlings, preventive methods of protecting plants from pests and diseases are necessary.

Plant protection

plant development phase	a drug	dose	what influences
2 sheets	Previkur 60.7% water	12-13ml per 10l. water	against root rot, root growth stimulant
5 leaves	Confidor 20% w.r.c.	15 ml for 10 liters. water	against all suckers / aphids, thrips /
3-5days before disembarkation	Ridomil Gold 68% s.p. Urea	15-20g + 20-25g for 10 liters of water	against fungal diseases

When plants develop 2 leaves, the seedlings are spilled with Previkur's solution 60.7% a.s., adding it to the nutrient solution. This fungicide against root rot is also a root growth stimulator. The better the root system is, the more it is able to "pump" nutrients, the more powerful your plant will be. All these activities will be preventive. And we will work with systemic drugs to secure the plant for 1.5-2 months.

Before planting in open ground, the seedlings are hardened, exposing them to the street for 3-5 days. In very strong sun, spunbond / agrotex 17μm / can be applied to the plants for several hours to minimize stress.

When planting seedlings in open ground, it must be remembered that the root system of tomatoes practically does not work at soil temperatures below 14 ° C. At low temperatures, growth and absorption of phosphates by the roots is significantly slowed down. The underside of the leaf turns purple-red. This can be eliminated by heating the soil.

Plants need minerals to grow, bloom and bear fruit. The main nutrients include nitrogen, phosphorus, potassium, calcium / N, P, K, Ca /.

Nitrogen contributes to the development of leaf mass. Phosphoric acid strongly affects the fruit setting of tomato, cucumber, pepper. Potassium is involved in the development of the entire plant. Its deficiency causes uneven coloration of tomato fruits. The stalk appears green, the fruits are small, often cracked. Calcium participates in the formation of tissues and improves the physical properties of the soil by binding excess acids in it. The greatest efficiency is achieved only with a balanced ratio.

In addition to the basic nutrients, microelements are required for the growth and development of plants in minimal amounts. They must be in the soil.

Boron micronutrient fertilizers are used on well-limed soils, molybdenum - on acidic, copper - on peatlands.

By the appearance of vegetable plants, you can determine the lack of nutrients. N - leaves are pale green, then yellow, plants are small. P - leaves are dark green with reddish pigmentation, departing from the stem at an acute angle, stunted plants. K - yellow border along the edge of the leaf and lightening between the veins, the leaf is curled. Mg - chlorosis of old leaves. They turn almost white, but do not die off. Ca - growth points die off, chlorosis of young leaves. The roots are short, thickened, licky. MN-chlorosis of leaves, but veins remain green.

Good harvests to you!
