The use of biologically active substances in the technology of growing tomato F<sub>1</sub> Sherami in protected ground conditions

Relevance. The interest of vegetable producers in small-fruited tomato hybrids has been increasing recent years. This is due to the high commercial qualities fruits that do not crack, contain 3 times more sugars than large-fruited tomatoes, and their range use for canning salads also expanded. Goal: identify effective options biologically active substances conditions extended turnover winter greenhouses on plantings F 1 Sherami. Methods. Research was aimed at studying effect – sodium selenate a concentration 10-5, natural coniferous concentrate (2 mg/l), EpinExtra (0.2 mg/l) double triple combinations productivity cherry tomatoes treatment plants carried out 4 during growing season after picking, when planting seedlings permanent place, pouring first brush mass harvest. Results. As result research, it found above drugs increases Sherami hybrid. maximum yield according results 2018 2019 obtained variant using Selenate + KHN Epin-extra averaged 288.1 t/ha. Also, BAS had an content dry matter, macronutrients. Conclusion. preparations positively affected growth development plants. variation increase compared control ranged from 5.2 17.2 hybrid Epin-extra, 19 t/ha, which made possible obtain appropriate income level 272 thousand rubles/ha.
