Sažetak
Adequate microelements concentrations in agricultural plants, grain or seed, is very important for both, crops productivity and nutritive value of agricultural products. Maize genotypes show great variability in nutrients content, depending on growing conditions. The objective of present study was to determine effects of genotype and environment on grain yield and Fe, Mn, Zn and Cu concentrations in leaf and grain of maize inbred lines used as parental components of hybrids. Five inbred lines were grown in a field trial during 2003 and 2004 in the east Croatia on the very acid soil with pH(KCl) 3, 9. Growing season of 2003 was very dry and warm, while in 2004 above average rainfall was recorded. Highly significant effect of genotype and year was observed for the grain yield. Average yield across the years was 3.08 t ha-1, and it was significantly lower in 2003, due to severe drought. On microelements in leaf higher influence of genotype was found, while for microelements concentrations in grain effect of year was also significant. Average concentrations (in mg kg-1) were 143 Fe, 185 Mn, 47.7 Zn and 15.0 Cu for the leaf, and 30.7 Fe, 5.4 Mn, 24.5 Zn and 7.02 Cu for the grain.
