يهدف البحث إلى دراسة الكفاءة الاقتصادية لاستخدام مياه الجفت في تسميد أشجار الزيتون , حيث شملت عينة البحث /294/ مزارعاً في محافظة اللاذقية بالاعتماد على المنهج الوصفي التحليلي , و توصلت النتائج إلى أن تسميد أشجار الزيتون بمياه الجفت ذو ريعية انتاجية عالية , حيث يحقق ربحاً صافياً قدره (33668) ل.س/دونم/سنة بينما بلغ هامش الربح الإجمالي نحو (61235) ل.س و معامل الربحية قياساُ إلى تكاليف الانتاج نحو (41.32%)%، بينما بلغ معامل الربحية قياسا الى راس المال المستثمر نحو 42.98%.
The research aims to study the economic efficiency of olive mill wastewater (OMWW) use in fertilizing olive trees, Which included research sample / 294 / farmer in Lattakia Governorate, depending on the descriptive analytical method,And found the results to be to fertilize the olive trees with (OMWW) rents high productivity, Where it posted a net profit of (33,668) SP / acre / year, while gross margin stood at (61 235) SP , The coefficient of profitability compared to the cost of production (about 41.32%)%, while the profitability coefficient was compared to the capital invested approximately 42.98%.

Verticillium wilt is one of the most serious disease that affect olive trees, and it is
spread all over the world where the olive trees grown. It is caused by the soil – borne
fungiVerticilliumdahliaekleb. Whichhas a wide host range, and forms amic
roseclerotia that
survive for long time in the soil.and it is difficult to manage.
In this studya survey was carried out in order to determine the incidence and severity
of infection on olive trees in Lattakiaduring2015.
The results showed that the highest percentage of infection and severity were on the
Kaissicultivar in ALqurdaha (10.68% , 4.05%) respectively , and the lowest percentage of
infection and severity were on the Safrawicultivar in ALqurdaha (3.92% , 0.97%)
respectively.
3,4-dihydroxybenzoic acid is one of phenolic compounds that exists in olive mill waste water (OMWW) and different industrial wastewater.Commercially activated charcoal was studied as absorbent of polyphenols. The value of specific surface area was 73
6.7189 m2/g. Equilibriums of 3,4-dihyroxybenzoic acid from aqueous solutions on four different particle sizes of the adsorbent with diameters ranged A(1000-2000), B(500-1000), C(250-500), D(125-250)m was examined at different initial concentrations ofabsorbate. The experimental data were analyzed using the Langmuir and Freundlich isotherm models. Both the isotherm models fit the adsorption data. Monolayer absorption capacities Q0 calculated from Langmuir equation were (0.36, 0.23, 0.34, 0.35mmol/g) for the different granular activated carbon sizes (A,B,C,D) respectively. The values of constant Kf calculated from Freundlich equation were (0.75, 0.61, 0.76, 0.79mmol/g) for the four sizes of granular activated carbon (A,B,C,D) respectively.
The results show that the charcoal activated carbon can be used as absorbent for polyphenol compounds.

The present study contains results of some experiments that had been
carried out to study the advantage of olive mill waste water (OMW) use ability
and in sugar's factories wastes in Syria as fungi cultures to produce stall-feed
rich in proteins.
The results showed that Geotrichum rich in proteins had been grown and
geminated more rapidly and revealed that inorganic nitrogen additions
(nitrates or ammonia) to the culture have advanced the fungi growth which is
rich in proteins, the highest quantity of proteins was (8.6 g/l) in NH4NO3 (1.5%)
media and urea (2.0%) media whereas the fungi biomass was higher with
NH4NO3 (1.5%) than with urea (2.0%).
In this study, we review the possibility of production both ethanol and methanol from
OMW(OMW: Olive Mill Wastewater), fermented using pathogenic bacteria and isolated
marine bacteria. The results showed that when using Salmonella sp. bacteria, the
highest
values of methanol (5658.308 μg /l) appear at 7.5% concentration of the OMW, and the
higher concentration of ethanol (49.132 μg/l) at a concentration of 17.5% fermentation of
OMW. While Pseudomonas sp. produced the highest concentration of methanol (603.76μ
g/l) and ethanol (688.71μg /l) at 17.5% for OMW.
The results of this research showedthe ability of the bacteria isolated from sea water
in producing the above mentioned alcohols; for example the X3 bacteria displayed a direct
correlation between high concentrations of OMW (15 , 35 , 50)% and the high
concentrations of produced methanol (UL, 130.406μg/l, 1353.244μg/l ), apposite to
ethanol which was under the detection limits (under limited: UL).
