Improving the technology of growing tomatoes in spring greenhouses is accompanied by a change in the variety of crop. Hybrids of the indeterminant type are becoming more common. The main purpose of the research was to study different ways of forming plants of tomato hybrids with an indeterminant type of growth in spring greenhouses. The research was carried out in 2018-2020 at the Breeding Center in the Rostov region. The material for the research was tomato hybrids with an indeterminant type of growth of its own breeding F1 Armada, F1 Pegas, F1 Ognevskiy and F1 Rozovy Fregat. Experiments were conducted in unheated spring greenhouses of hangar type with polycarbonate translucent coating in the soil culture. Substrate is ordinary black earth. The contents of the main elements of food - high, pH soil solution 7.0-7.2. Plant planting scheme 70×30 cm, 10 plants of each variant in four-fold. A fertigation drip system was used for watering and feeding. Harvest was carried out in several receptions as the fruit matured. Studies have shown that the formation of plants affects the height of plants and their obliging. As the number of shoots left, the height of the plants decreases and the area of the leaf surface increases. The increase in the number of abandoned shoots leads to an increase in the total number of brushes on the plant, but the number of fruits formed in the brush, decreases, as well as the average mass of the fruit on the plant. The highest productivity of plants and their yield from a unit of area is achieved when formed in 2 stems. And this is typical for all hybrids, regardless of individual features of growth and development.
Key words: spring greenhouses, tomato, indeterminants hybrids, plant formation, architecture, yield.
