Abstract The article presents the results of the research dealing with the dependence of the mass, growth processes and the attachment height of the low bean of soybean under the application of different types of fungicides and biopreparation Rhizoactive in the Right Bank Forest-Steppe of Ukraine. Application of different types of fungicides had a positive influence on the plant mass of soybeans, growth processes and attachment height of a low bean. Indexes were defined in different years and at different development stages of a plant: budding, flowering and beans maturing. Throughout all development stages, the best indexes of soybeans height, their mass and attachment height of a low bean were under the complex application of preparations, in particular, the highest indexes were in the variants with the application of fungicides Impact K, 0,9l/ha; Koronet 300 SC, KC 0.8 l/ha at the background of seeds treatment with the inoculator Rhizoactove. Important selection features that are associated with the main morphological and biological characteristics of soybeans are the height, mass and lower bean attachment height of soybean. Productivity in general depends on the height and weight of plants, as the stem is an organ of conversion and transport of organic and mineral substances, which plays an important role in crop formation. Technology of soybean cultivation on irrigation provides suitability of varieties for mechanized harvesting, including resistance to pod shatter and lodging, optimal placement of the first beans on the plant and genotypes reaction to irrigation. For successful introduction into production, new soybean varieties must be not only high yielding but also suitable for mechanized harvesting, which is primarily due to the lower bean attachment height of the plant. Low first bean attachment leads to a decrease in the yield of the variety, since a significant number of beans are lost during combine harvesting. Yield losses because of the low attachment of the lower bean may reach 15-20%. This feature is associated with the total height of the plant. The height of soybean plants and the lower bean attachment largely depend on growing conditions. The research conducted by A.Ya Ala. and A.A. Hamolin have established that linear parameters of plants at irrigation considerably increase. In the south of Ukraine irrigation causes significant changes in the biology and structure of soybean plants.
