tomato

Tomato with the scientific name Solanum lycopersicum is one of the great flowering plants, belonging to the order of Dicotyledons.

Figures
Tomatoes have many differences from each other in terms of plant growth, fruit quality, fruit shape, and resistance to diseases and pests. This plant can be seen in yellow, red, and orange colors. In terms of shape, round, oval, smooth, Congress is divided into large and small sizes.

Cultivation in the greenhouse
Temperature is one of the important factors in growing tomatoes. A temperature between 18-20 degrees Celsius will have a favorable result.

Tomato needs a lot of light in areas where there is not enough light in winter and autumn. We must be careful about its cover and location. For young seedlings, the lighting hours should not be more than 17 hours.

It needs a lot of water for its growth and development, as well as because of the many products it produces. Dehydration and being untidy at the end of the plant’s growth period causes physiological diseases. Greenhouse tomatoes during the growth period 65 It consumes liters of water. Therefore, about 300 to 340 liters of water is needed for each square meter of cultivated area.

The soil for growing tomatoes must have proper ventilation, store water and nutrients, be free of pollution and can be disinfected without having any side effects on the plant.

Planting tomatoes

In temperate regions, about fifty to sixty days before planting in the main place, the seeds are planted in the chassis, greenhouse or treasury, and in the beginning of April after the cold is over, they take out the seedlings from the treasury and plant them in the main land. It takes place in tropical regions in late winter.

Planting is done in the form of stacks with a shallow atmosphere, which is the same as the Farrow system.

fertilization
Tomato soil should be rich in nutrients and organic matter. The amount of manure given to tomato land depends on the soil fertility, the type of land, the previous crop, the amount of fertilizer given for the previous crop, soil organic matter, soil moisture, the growing season, the tomato variety and perhaps the planting method. For this purpose, the amount of 20 to 30 tons per hectare of rotted manure is suitable. Whenever manure is applied to the ground, it must be plowed under the soil.

Tomatoes need calcium, potassium and nitrogen in sufficient amounts. The lack of supply of these elements will weaken the plants and reduce the quality of tomatoes. The use of complete chemical fertilizers plays a significant role in increasing yield. The amount of nitrogen and phosphorus fertilizers Potassium should be more. 300-250 kg of nitrogen can be used.

For the production of foliage, nitrogen is obtained through soil organic matter and chemicals such as urea and calcium nitrate. The required nitrogen fertilizer is applied several times.

Phosphorus is needed for the production of flowers, fruits and rooting. And 200-150 kg and if needed 100-150 kg of potassium can be used. Sulfur also has a good effect on tomatoes.

Among the fertilizers that are produced by Yadnegar Structures Company (Cinco) and can be used for tomatoes, they can be calcium acetate fertilizer, liquid calcium fertilizer, potassium acetate, urea phosphate, liquid sulfur fertilizer, and complete chemical fertilizer. NPK pointed out.
