*2.3. Grain Quality Analyses*

The crude protein content (CPC) was analysed according to the Kjeldahl method [9] (CSN EN ISO ˇ 20483). The Zeleny's sedimentation test (ZST) was analysed according to the CSN ISO 5529. Owing to ˇ the different issues, the quality parameters (CPC, ZST) from the Caslav were analysed only in grain from seasons 2015 and 2018.
