In two-year experiment in apple orchard on calcareous soil in eastern Croatia, N fertilization and crop load influence on fruit macroelement content and fruit quality was investigated. The effect of year was significant in all tested parameters except Ca and Mg content in fruits, with higher values observed in dryer 2003 year. The applied N fertilization and crop load did not influence any of tested parameters except fruit weight. The interaction of year and crop load had an impact on fruit Ca content and fruit weight, which was negatively related to all macroelement concentrations as well as fruit dry matter content, total acid and total sugar content in given experimental conditions.
