أجريت تجربة حقلية في محافظة طرطوس, على محصول الفول السوداني في الموسمين الزراعيين (2013-2012)-(2014-2013) مكّونة من 6 معاملات: شاهد (بدون تسميد), و معاملات استخدمت فيها معدلات مختلفة من مياه عصر الزيتون (OMWW) (5-10-15) l/m2 السماد العضوي (روث الأبقار) بمعدل ( 30 ) طن/ه, و السماد الآزوتي بمعدل ( 30 ) كغ/ه. هدف البحث إلى معرفة تأثير هذه الإضافات في بعض المجاميع الفيزيولوجية للكائنات الحية الدقيقة, و عدد العقد البكتيرية المتشكلة على جذور النباتات, إلى جانب إنتاجية محصول الفول السوداني.
A field experiment was conducted in Tartous Governorate, on the Arachis hypogaea . L during tow growing season (2012- 2013)(2013-2014). Experiment was included 6 treatments with three replicates: control (without fertilization), different rates of Olive Mail Waste Water (OMWW) (5-10-15) l/m2 , organic fertilizer (30 tn/h)and nitrogen fertilizer(30)kg/h. The research aimed to know effect of these Additions on some physiological groups of microorganisms, nodulation on plant roots and nitrogen relative bacteria Arachis hypogaea . L. yield.

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%.
The aim of this research, is to use Liquid–liquid extraction to separate
phenolic compounds from olive mill wastewater resulted from three-phase
centerfuge extraction (OMWW). Four solvents were used: Methyl iso butyl
ketone (MIBK), Ethyl acetate (
EtOAc), Octanol-1 (C8H18O), and Noctanoylpyrrolidine
(OPOD) which was synthesized in our lab. The effects of
pH and Extraction stages on the efficiency of total phenolic compound
extracted from OMWW were determined by Folin - Ciocalteu
spectrophotometric method. Ferulic acid (FA) and Caffeic acid (CA) were
determined in extractants by HPLC. The COD value in water phase of the four
extracts was measured together with the reducing power and radicalscavenging
effects for the extracts. We compared the antioxidant activity of
MIBK, OPOD extracts, with ferulic acid (FA), caffeic acid (CA), ascorbic acid
standards and rosemary.
The results showed that MIBK had the highest extraction efficiency and
gave the maximum quantity of phenols from OMWW, than OPOD, C8H18O,
EtOAc. The COD value was decreased about %94.5 by MIBK, %83.7 by
OPOD,%81 by C8H18O, and%72 by EtOAc. The phenols extracted by MIBK
could be added to eatable oils as natural antioxidants, because they were
superiority on rosemary, and nearly to caffeic acid (CA) standard.
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 experiment was conducted during 1998 and 1999 seasons in the field of
the left bank of Euphrate river at the Ramadi town. The soil texture was sandy
loam and loam, using peanut (Arachis hypogaea L.) local variety (semi-erect).
The objective wa
s to investigate the optimum spacing between the rows (50, 75,
100 cm) and within the rows (20, 35, 50 cm), using factorial experiment within
randomized complete block design with three replications.
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%).
