This investigation was carried out on fifteen years old Sorani and Kaissy
olive cultivars (Oleaeuropaea L.) trees grown in Basaltic soil that
was poor in organic matter and potassium.
The aim of the present investigation is to study the effect of
different
amount of organic and potassium fertilization on yield, fruit weight,
oil percentage, and oil acidity.
Results obtained showed that the highest value of fruit weight, yield, and
oil precentage exhibited statistically the highest values by trees
fertilized with the treatments (Organic + Potassium).
Acidity increased in (Organic + Potassium) treatments but it was less than
2% oleic acid , while it was less than 1% oleic acid in Potassium
treatments and in Organic treatments (Extra vergin oil).
This research aimed to evaluate the growth and productivity of planted Pinus pinea
in pure stands at "DAHR AL SORANI" forest site. The site is about 50 km north east of
Tartous city, which is located in Temperate-Humid Bioclimate Zone.
Results sho
wed that the stands were not equivalent in growth indicators; this was due
to many factors affecting growth like site characteristics and trees density…etc. In spite of
the mediocre values of form factor, the volume and mean of annual increment was not
influenced.
Results revealed that the mean values of tree density was 851 trees/ha and ranged
between 350 - 1975 trees/ha, woody volume was averaged at 116.337 m3/ha and
ranged between 51.6519 - 215.3635 m3/ha; annual increment had also an average of 4.4548
m3/ha/year and ranged between 1.9866 - 7.9764 m3/ha/year.
The study showed a high straightness of pine. Pinus pinea trees had very rarely
forked boles.
