Subject of the discussed studies was an analysis of the impact of mineral multicomponent fertilizers, from Polish and foreign producers, on the yield and yield components of
winter oilseed rape (Brassica napus var. oleifera). Two field experiments were carried out in
2015–2017 in Lipnik. The experimental crop was winter oilseed rape, hybrid cultivar DK
EXPLICIT. Two factors were studied in the experiment A: 4 multi-component mineral fertilizers
- two Belarusian (1 i 2), one Russian and one Polish (Polifoska 6) and 4 doses of fertilization
(250, 500 and 750 kg ha-1
). In the experiment (B) were compared two factors: 3 multi-component
mineral fertilizers - Belarusian, Russian and Polish production - Polifoska 8 and 4 doses of
fertilization (200, 400 and 600 kg ha-1
). The fertilizers applied in the experiments, manufactured
in Belarus, Russia and Poland, did not show variations in the amount of yield of winter rape. The
number of winter rapeseed plants on the area unit (in autumn and spring) was independent of the
type of fertilizers. In the experiment B, higher number of rapeseed siliques was obtained after
application of Polifoska 8, than other fertilizers. Rapeseed grown on soil with the fertilizers
manufactured in Belarus showed a lower value of greenness index (SPAD) and leaf area index
(LAI). As a result of the application of multi-component fertilizers, manufactured in Belarus,
Russia and Poland, the recorded differences in the winter rapeseed yield, yield components and
physiological parameters did not exceed 10%.
