Recently, scientists and producers have been paying increasing attention to niche crops that are able to significantly diversify the monocultural oil field of dominance in the crop rotation of sunflower, soybean and rapeseed. In today's climate, one of these crops is mustard, which at the same time, with the ability to form stable yields of seeds and raw materials of good quality, is distinguished by its relative unpretentiousness to external factors. Purpose. Improvement of elements of technology of cultivation and determination of their influence on productivity of mustard white. Methods. The studies involved the use of standardized methods: field – to determine the yield, biometric records and measurements, laboratory – to determine the agrophysical properties of the soil, the content of the basic nutrients in it, to determine the structure of the crop; calculated – evaluation of the economic efficiency of the elements of white mustard growing technology studied; statistical – analysis of variance. The article presents the results of studies to study the effect of different doses of fertilizers, micro fertilizers on seed yields and oil the content in white mustard seeds. Optimal parameters of elements of technology of cultivation of mustard white, which provide maximum yield in the conditions of the northern forest-steppe of Ukraine, are established. As a result of the research, it was found that the highest seed yield of white mustard seed (2,58 t/ha) with oil content (43,29 %) was provided by the application of fertilizer with fertilizer at a dose of N45P60K90 and foliar feeding with Tropicel. The significance of the influence of the investigated factors on the crop yield is estimated. It was established that in 2016–2018. factors in terms of the degree of influence on the yield of the white mustard variety Belaya Princess in terms of importance can be arranged as follows: mineral fertilizers – 14.3 %, treatment of crops with micronutrient fertilizer Tropikel – 52.2 %. Cost-effec-tiveness analysis showed that profitability (225 %) and profit (UAH 32158) reached the highest values by growing white mustard using technology that involves the introduction of N45P60K90 and foliar fertilization of Tropikel microfertilizers. Keywords: mustard white, mineral fertilizers, micro fertilizers, yield, seed quality, cost-effectiveness, Tropicel.
