In the lead up to flowering, you need to ensure your trees have adequate nutrition, particularly of Boron and Calcium. A lack of Boron and Calcium may lead to decreased fruit set, oil quality and oil stability.
A study on olive trees has looked at different application rates of Boron and Calcium and the effects on fruit set, fruit oil and oil chemical characteristics.
Fruit Set %
From the overall data, the two studied nutrients effectively increased fertilisation either through controlling pollen germination on the stigma or growth of pollen tube through the style. Therefore, the subsequent increase in fruit set % was observed.
Fruit oil %
Furthermore, the effects could also be seen in increased fruit oil content. This increase reached a significant level in most cases.
Oil Chemical Characteristics
