文摘
- •
Experiments with fractional factorial design support quick analyses of growth requirements in new cultivars.
- •
The yield of semi-dwarf cultivars was 3–13% lower in comparison with the long-stem cultivar.
- •
Delayed sowing decreased the seed yield of semi-dwarf cultivars.
- •
Both morphotypes delivered highest yields at a seeding rate of 80 pure live seeds m−2.
- •
Nitrogen fertilization at 240 kg ha−1 N exerted a yield-forming effect in both morphotypes.
- •
The analyzed morphotypes of winter oilseed rape responded similarly to the applied disease control measures.
