E. Kołota; K. Czerniak DOAJ (DOAJ: Directory of Open Access Journals) 2010
Other claims from this paper (8)
- Intervention effect Higher nitrogen doses gave small, nonsignificant additional yield efficiency.
- Intervention effect Heavy nitrogen fertilization raised total N in both edible parts.
- Intervention effect Heavy nitrogen fertilization raised nitrates in both edible parts.
- Intervention effect Heavy nitrogen fertilization raised magnesium in leaf petioles.
- Intervention effect Heavy nitrogen fertilization reduced sugar content in leaf blades.
- Observation Leaf blades averaged higher dry matter, sugars and total N than petioles.
- Observation Leaf blades averaged higher Mg than petioles.
- Observation Petioles averaged more calcium and nitrates than blades.
