Essay

The dissertation covered the theoretical justification and practical description of issues of growth and development and formation of productivity of soybean varieties under the influence of seed inoculation in interaction with mineral fertilizer and subsequent foliar fertilization in the conditions of the Right Bank Forest Steppe of Ukraine. The correct choice of mineral nutrition for growing soybeans provided general stimulation of plant development without problems with the subsequent formation of the legume-rhizobial relationship and its functioning from the point of view of assimilation of nitrogen from the atmosphere. Which emphasizes the role of small doses of starter nitrogen fertilizers from the standpoint of better crop development, especially when combined with foliar feeding of plants during the growing season. Even with the maximum need of plants for nutrients at the time of formation of beans, seeds and pouring of seeds - their good start at the beginning of the growing season forms an advantage in the future, thanks to better rooting, development, work of the legume-rhizobial apparatus, etc. And therefore, against the background of the main fertilizer in N30Р60K60, foliar fertilization with Fulvohumin in combination with pre-sowing soybean bacteriization affected the formation of a good level of productivity. Without exception, all soybean varieties increased the level of yield on these options, that is, we observed a general stimulation of plants in terms of the response to changes in the level of yield. However, the high yield was in Eurydice varieties - 3.70 t/ha, Aratta - 3.76 t/ha, Orpheus - 4.02 t/ha, and we determined the best yield indicators over the years of research in such soybean varieties as: Azimut – 4.11 t/ha, Triada – 4.12 t/ha and Aurora – 4.16 t/ha.
