In the field experiment the influence of foliar fertilizers Agrosol Eko-Z, Insol 3 and Plonis 1 applied in two rates as well as that of the adjuvant Atpolan 80 EC on the yield and grain quality of winter wheat cv Roma was estimated. The results confirmed possibilities to increase the yield due to foliar application of liquid fertilizers. The yield increase (0.7-2.7 dt•ha-1 depending on kind of the fertilizer) did not decide positively about economical viability of this practice. Results of Atpolan 80 EC application with foliar fertilizers indicated potential possibilities to improve the effectiveness of fertilization by using different adjuvants. Interaction of Atpolan 80 EC, kind and rate of fertilizer show that it is necessary to look for the most adequate components to be used in the system: foliar fertilizer - adjuvant.
