A three years (2016-2018) field experiment was conducted in the Left-Bank Forest-Steppe of Ukraine to assess the influence of 7 different treatments with foliar fertilizers and plant growth regulators (control; Sol Bor + Basfoliar 6-12- 6; Basfoliar 6-12-6; Wuxal Bio Aminoplant + Wuxal Boron; Wuxal Boron; Spectrum Askorist + Spectrum B + Mo; Spectrum B + Mo) on seed yield and quality of 3 new confectionery sunflower genotypes (Confeta F1, Lakomka, Oniks). Foliar applications largely had a favourable effect on all parameters studied (plant height, leaf surface area, number of seeds per head, seed weight per head, 1000-seed weight, seed yield, and protein content) compared to the control. Significantly (P<0.05) higher average seed yield occurred in the variety Lakomka (2.42 t/ha). Again, the greatest average protein content was obtained from Lakomka (23.0%). Sequential foliar application of Sol Bor + Basfoliar 6- 12-6 thrice gave significantly (P<0.05) greater average seed yield (2.37 t/ha) for all three genotypes combined compared to the other treatments. Based on foliar sprays, the increase in protein content ranged from 0.1-0.5% compared to the control.
