The effectiveness of the use of biological products in the technology of growing tomatoes in protected ground

An important issue in vegetable growing is obtaining environmentally friendly and high-yielding products throughout the year. The purpose of the research was to evaluate the effective-ness of biological products in the technology of growing tomatoes in greenhouses. The studies were carried out in 2021-2022 in the conditions of the YSU greenhouse. I.A. Bunin. A compara-tive evaluation of the effectiveness of the use of biopreparations of the GumiAgro and BSKA-3 series on Merlis hybrid tomato plants was carried out. The maximum height of plants was noted on the variants treated with the preparation of the BSCa-3 series. The difference compared to the control after the 1st treatment was 1.3 cm, after the 2nd - 3.3 cm, after the 3rd - 7.4 cm, after the last - 8.4 cm. it was noted that tomatoes treated with biopreparations of the GumiAgro and BSKa-3 series in the 1st month of harvest exceeded the control in terms of weight and diameter. The maximum yield was observed when treated with BSKa-3, which exceeded the control by 2.6 kg/m2, and with GumiAgro by 0.9 kg/m2.
