**5.2 Nitrogen fertilization**

Nitrogen fertilization was applied four times per vegetation. One-third of urea (46% N) was applied in the autumn with the basic soil cultivation, and the twothirds were added pre-sowing. Top dressing was done twice with KAN (calciumammonium nitrate; 27% N). The first top dressing, one sixth of N was done in phase 6–8 leaves, and the last application, one sixth of N was done in phase 8–10 leaves.
