The results of researches on the influence of mineral fertilizers and foliar feeding of spring barley on fertilizers organic origin with the content of trace elements on the parameters of plant height on the dark gray podzolic soils of the Western Forest-Steppe of Ukraine. The research methodology provided for a two-factor field experiment. Factor A includes various backgrounds of mineral fertilizers: 1) Without fertilizer (control); 2) N45P30K30; 3) N60P30K30; 4) N45P45K45; 5) N60P45K45; 6) N60P60K60. According to factor B, was carried out foliar fertilizations during the vegetative period of fertilizers organic origin with the contents of trace elements on the background of mineral fertilizers: 1) Without foliar feeding; 2) Fertigrein Foliare; 3) Freya–Aqua.

It was established, that foliar fertilizations of crops on the different norms for the introduction of mineral fertilizers good affects on biometric parameters, in particular, the height of spring barley plants. The highest growth rate was obtained on the background of making the N45P45K45. Fertigrein Foliar feertilizer contributed to obtaining a plant height at the level of 83,4 cm, which grew relative to the option without feeding by 1,3 cm. As a result of foliar fertilization with the Freya–Aqua fertilizer on the background of N45P45K45 a maximum height value received of 84,1 cm the indicator without feeding is 83,4 cm.

It was noted, that the growth of plant height on different backgrounds of mineral nutrition it positively influenced the indices in yields of culture. As a introduction of N60P30K30 and foliar feedings Fertigrein Foliar and Freya–Aqua, the yield increase relative to the option without feeding was at the level 0,14 and 0,26 t/ha. It is proved, that the variant with the norm of mineral fertilizers N45P45K45 obtained the highest yield for the introduction of fertilizers organic origin with the content of trace elements. The use of Fertigrein Foliar against this background was shown in the receipt of the indicator at 4,30 t/ha, the increment to the option without without feeding was 0,24 t/ha. The highest yield yielded the use of Freya–Aqua against the background of N45P45K45, where it was 4,38 t/ha, ie increased by 0,33 t/ha.

Installed a tight correlation link crop between yield and plant height by joint introduction of mineral fertilizers and fertilizers of organic origin with the content of trace elements of Freya–Aqua, which is described by the determination coefficient of 0,96.
