In the article the results of studying of features of role of trace elements in the formation of the quality indicators of seeds of oilseed radish in two varieties are reflected. Systematized the views of various researchers on the processes of formation of oil content in cruciferous crops in general and radish oilseed in particular, given the current strategy of fertilizer oilseed crops of the family Cruciferae. Studied feature of the stages of the implementation and effectiveness of mono-component micronutrients in the form of easily soluble and readily available substances.  The studied set of microelements included the recommended list of physiologically important components of modern microfertilizer formats and their chemical composition in order to optimally analyze the effectiveness of application for their single application in two key phases of oilseed radish – the phenological phase of stalking and the phenological phase of flowering. The use of each of micronutrients was effective and substantial compared to the oil content of seeds of both cultivars of oilseed radish given the level of oil content in seeds in control variant. The magnitude of the variation in the oil index was estimated taking into account the differences in the nature of the hydrothermal regimes of the research period. This allowed to determine the degree of genotypic nature of the formation of the oil content of seeds in oilseed radish and the possibility and effectiveness of selection of appropriate genotypes with the prospect of obtaining oil in the technical direction of use. Also assessed the role of individual micronutrients in the magnitude of the volatility of oil content in seeds of oilseed radish. Determined that the increase of oil content in seeds of oilseed radish the addition of various trace elements in the range of 0.3-1.4% from the close dynamic the resulting effective action on the formation of this indicator in the form of Сo>Zn>Cu>B>Mn>Mo. It is proved that the efficacy of these minerals increases with introducing them into the flowering stage, which is a critical period regarding the implementation of the reproductive potential of the plants of oilseed radish and the formation of appropriate indicators of the quality of its seeds. The recommendations for further research in the field of optimization of fertilizer radish seeds and micronutrients were formulated.
