Sažetak
The scope of this research was to determine concentration of chloroplast pigments in the winter wheat leaves influenced nitrogen fertilization under reduced soil tillage. The research for winter-wheat has been conducted at the Virovitica-Podravina County in 2008/2009 , with six different nitrogen rate (controla-0 kg N ha-1, 30 kg N ha-1, 60 kg N ha-1, 90 kg N ha-1, 120 kg N ha-1, 150 kg N ha-1, respectively) with following continuous soil tillage treatments: CT – conventional soil tillage, based on mouldboard ploughing ; DH – multiple pass diskharrowing ; and NT – No-tillage. The chloroplast pigments have been measured in stem extension (after Feekes: 6.0). This research showed that chlorophylls are very sensitive to changes in nitrogen content: concentration of chlorophyll a, chlorophyll b, chlorophyll (a+b) and carotenoids increased with higher fertilization rate. Tillage did not significantly effect on concentration of chloroplast pigments.
