Effect of Kaolin and Calcium Carbonate on Flowering initiation and fruit set of Kalamata and Manzanillo Olive Trees

Abstract

This work was carried out through 2015 and 2016 seasons on two olive cultivars (Kalamata andManzanillo). Trees were 15 years old, grown in sandy Soil and planted at 5 X 5 meters apart underdrip irrigation system. This investigation aimed to flowering parameters and fruit set of the two olivecultivars. Trees sprayed with concentration of Kaolin and Calcium Carbonate at (3, 5 and 7%) in threedifferent dates (mid October, November and December). Results proved that spraying withAl2Si2O5(OH)4 7% and CaCo3 7% treatments gave the highest number of inflorescences per shoot,number of flowers per inflorescence and sex ratio with good fruit set on mid-December in Kalamatacv. While, Manzanillo cv. gave with the same concentrations on mid-November a good initial andfinal fruit set with lowest fruit drop percentage.
