Abstract
Influence of foliar nutrition with nitrogen, potassium and boron in comparison with untreated control trees on the level and seasonal changes of nitrogen, potassium and boron in the olive fruits cv. Oblica was observed over the growing season. The concentration of nitrogen and potassium in the fruit was gradually rising during the growing period until the time of fruit ripening, but the differences caused by foliar application of N, K and B were not significant. Foliar application of boron caused significantly higher fruit boron content. Significant positive correlation between oil and potassium content in the fruit was observed.
