In order to study the impact of a comprehensive system of drugs of bacterial origin, the company BTU-Center monitored biometric indicators and productivity of sweet pepper in the open ground of the Right Bank forest-steppe of Ukraine. The early-ripening variety of sweet pepper Aphrodite was used for research. Organic cultivation technology was used in the experiment. Dosing of biological products was carried out according to the manufacturer's recommendations, and the dose of drugs was doubled. Biometric parameters varied depending on the dose of biological products. During the growing season, the height of the plants of the control variant was 32.1 cm, but with the use of the recommended dose of biological products, the height of the plant was 35.3 cm, which is 3.2 cm higher than the control variant. The use of a double dose of biological products provided the highest rates of plant height. The larger diameter of the stem was obtained by applying a double dose of biological products - 8.5 mm. As a result of the use of biological products, the stem diameter exceeded the control variant by 0.8 and 0.9 mm, respectively. In studies, the fruits in all respects corresponded to the technical characteristics of the variety, but their weight was variable. The highest average fruit weight was characterized by plants using a double dose of biological products - 138.9 g. The study indicators exceeded the fruit weight of the control variant by 9.1 and 10.4%. The highest average yield was obtained with a double dose of biological products - 26.4 t / ha. In these variants, the excess yield relative to control was 9.3 and 11%, respectively. As a result of the application of the recommended dose of biological products, the stability of Lewis was - 1.18, and with the use of a double dose - 1.16. The use of organic technology in open ground significantly improves the biometric performance of sweet pepper plants. The use of organic cultivation technology increases the number of fruits per plant, but doubling the dose of biological products does not give a significant advantage over the recommended application rates.
