In the conditions of the Republic of Belarus there was analysed influence of different doses og mineral fertilizers (macro – and trace elements) on yielding capacity and quality of oil seeds of sunflower (Helianthus annuus). The following experiments were realized: N60P60K120; N90P80K150; N120P100K180; N120P100K180 + B0.5 (boracic acid); N120P100K180 + B0.25+0.25 (boracic acid); N120P100K180 + B0.5 (Ekolist Mono Bor); N120P100K180 + B0.5 + 0.25(Ekolist Mono Bor). Research conducted at the sod-podzolic sandy soil, have shown high efficiency of both macro-and micronutrients. Mineral fertilizers also promote increase in sunflower seeds productivity. Productivity of sunflower seeds on average over three years was 34,3 - 44,7 kg/ha. Application boron fertilizers in various forms and doses on background N120P100K180 yielded 42,3- 44,7 t/ha with a fat content in the seeds of 46,9 ... 47,4%. Oil yield from 1 hectare to these options amounted to 19,8-21 centers.
