In this research, the effect of foliar spraying, with macro
and microelements on the productivity of Sourani olive variety, was studied in
Arab-Said village (which is 5 km west of Idleb), during the years 2012-2013. A
randomized block design was used, and 4 treatments were performed, each of
which contained 5 replicates, each replicate was one olive tree. During the
experiment, foliar spraying was applied with a mix of macro and microelements,
so that the treatments differed between them by the number of sprayings (0, 1,
2, and 3) and their dates (before flowering, one week after flowering, and two
weeks after the second spraying). The results showed that all foliar spraying
treatments outperformed the control, with a significant increase, in most of
the indicators and parameters studied: the leaf surface (2.41 cm2), the number
of flowering cluster/branch (13.32), the number of flowers/flowering clusters
(8.88), the number of flowers/branch (359.2), the percentage of fruit-set
(0.61%), the number of fruits/branch (24.41), the fruit weight (0.98 g), the
fruit size (0.49 mL), and pulp/fruit ratio (3.43%). Where spraying once before
flowering had the most significant increase compared to other spraying
treatments. While the increase in the number of spraying times did not have any
significant effect on the previous indicators, it led to a significant increase
in the vegetative growth index (6.75cm), in the productivity/tree (39.42 kg),
and in the percentage of oil (5.28%), compared to the control. Finally, the
results showed that production varied greatly between the two years of the
study (the phenomenon of alternate-bearing), but that all experimental
treatments reduced this difference comparing to the control.
