Tomato hybrids recommended for growing in photoculture conditions

Relevance. The most important influence on the yield, the timing of growing vegetables in greenhouses and the cost of the resulting crop, in addition to the arrival of solar radiation, is exerted by the presence of a system of artificial lighting in greenhouses and its capacity. It is no exaggeration to say that today artificial lighting in greenhouses is more effective than natural lighting. So, to obtain one kilogram of vegetables using artificial lighting, it is necessary to spend 4.5-5.0 thousand J/cm2, and in the case of natural lighting: 5.0-6.5 thousand J/cm2. This is due to the fact that when using artificial lighting in the greenhouse, we create the most comfortable growing conditions for the plants. Of course, every culture, every hybrid requires its own illumination parameters, so you should not try to formulate what the ideal artificial lighting will be. Proper lighting means getting the maximum yield from your crops at the lowest cost. An increase in the productivity of plants when grown under photoculture conditions occurs not only due to an increase in the lighting power per unit area of greenhouses, but also due to correctly selected hybrids. The cultivated hybrid is one of the most important criteria for both increasing its productivity and improving the quality of the fruit. But not all tomato hybrids recommended by breeding companies for growing under artificial lighting are ideal for such conditions. Methods. The methods used in agronomic science were used. The information base of the research was made up of reference materials from specialized publications on the subject under study (catalogs of breeding companies); materials received from participants in the greenhouse vegetable market (breeding companies, greenhouse plants); own research, articles and reviews in specialized journals. Results. Correctly selected tomato hybrids provide a significant increase in productivity in greenhouses, an improvement in fruit quality and a balanced cultivation technology under these conditions. An assortment of recommended tomato hybrids for growing in photoculture conditions is presented, an analysis of their advantages and disadvantages is made, and the main requirements for hybrids for these conditions are formulated.
