Phosphorus, Calcium and Magnesium status in maize genotypes grown on acid soil
The response of five maize inbred lines and their three commercial hybrids to acid soil with low nutrients availability were studied in a field trial over a three year period (2003 to 2005) in the east Croatia. Grain yield and P, Ca and Mg concentration in leaves were analysed. Highly significant effects of the both, year and genotype for all traits were determined. Grain yield of maize genotypes ranged from 5.11 t ha-1 in dry year to 7.39 t ha-1 in more favourable year. Regardless of low soil P content, an adequate P status (3.17 g kg-1) in maize were found, while lower Ca (5.62 g kg-1) and Mg (2.36 g kg-1) mean concentrations in leaves are consequences of their low level in soil. However, considerable differences in P, and especially Ca and Mg status were found among parental lines, what was reflected on their progeny. The results indicated that origin of inbred line may have an important role for nutrient content inheritance.
