The results of variety trials with winter oilseed rape in the Slovakia in 2015/16

In the season 2015/16 we established two large semi-practical trials with winter oilseed rape in Slovakia: (Hul and Liptovsky Mikulas) with 25 varieties (24 hybrids and 1 line) and two thematic trials (Prasice, Upor) with 9 varieties (all hybrids) in two variants (1 lower seed rate without autumn N and 2 higher seed rate with 40-46 kg N/ha in autumn). In large variety trials, Fencer (4.99 t/ha), Cantate (4.96 t/ha) and line ES Valegro (4.95 t/ha) had the best yield results. Bluestar (45.3%), Anissa (45.3%), Shrek (45.1%), PT 225 (44.8%) and DK Exception (44.7%) reached the highest oil content. In thematic experiments, a variant with lower sowing rate without autumn nitrogen was more yielding in average by 0.25 t/ha. Varieties DK Exstorm (5.41 t/ha), Astronom (5.40 t/ha) and Shrek (5.30 t/ha) reached the highest yield.
