نفذ البحث في مركز البحوث العلمية الزراعية في محافظة حماه خلال عامي 2020و2021 بهدف دراسة تأثير الرش الورقي بمستخلص الطحالب البحرية في نمو وانتاجية شجرة الزيتون صنف قيسي ، حيث طبق الرش ورقي بمستخلص الطحالب البحرية alga 600 تركيز (0,5غ/ل) وفق المعاملات: A0 شاهد بدون رش مستخلص طحالب بحرية، A1 رشة واحدة قبل الإزهار بأسبوع، A2 رشة واحدة بعد العقد، A3رشة واحدة قبل القطاف بشهر، A4 رشتان (قبل الإزهار و بعد العقد)، A5 رشتان (بعد العقد وقبل القطاف بشهر)، A6 ثلاث رشات (قبل الإزهار وبعد العقد وقبل القطاف بشهر). مع إضافة التسميد الأرضي حسب التوصية السمادية. بينت نتائج التسميد الورقي تأثير معنوي في صفات النمو الخضري حيث تفوقت معاملة قبل القطاف بشهر على باقي المعاملات بمتوسط طول طرود 6,94 سم بينما الشاهد 4,75 سم, في حين أثر مستخلص الطحالب البحرية بشكل إيجابي على عدد الأزهار الكلي حيث تفوقت معاملة الرش قبل الإزهار وبعد العقد على باقي المعاملات حيث بلغ متوسط عدد الأزهار 203,11 مقارنة بالشاهد بمتوسط عدد أزهار 164,19 وكذلك في نسبة عقد الثمار إذ كانت أعلى نسبة للعقد عند معاملة الرش قبل الإزهار 3,20 % وفي الشاهد 2,19 % كما أظهرت النتائج تفوقاً واضحا في إنتاجية الشجرة خصوصاً المعاملة قبل الإزهار وبعد العقد إذ بلغ متوسط إنتاجية الشجرة 37,07 كغ وفي الشاهد 14,07 كغ ، وقد لوحظ وجود زيادة معنوية في نسبة الزيت للثمار فقد تفوقت معاملة قبل القطاف بشهر معنويا على باقي المعاملات بكلا الموسمين حيث بلغت أعلى قيمة لنسبة الزيت 20,28 % تليها معاملة قبل الإزهار وبعد العقد وقبل القطاف بشهر بنسبة زيت 20,27 مقارنة بقراءة الشاهد 17,17%.
This research was carried out at the Agricultural Scientific Research Center in Hama, in seasons 2020, 2021 to study the effect of foliar spray of seaweed extract on the growth and productivity of the olive tree cv. Kaisi, Where the foliar spray was applied with seaweed extract called alga 600 in concentrate of (0.5 g/l) According to treatments: A0 control without spraying seaweed extract, A1 one spray one week before flowering, A2 one spray after fruit set, A3 one spray one month before harvest, A4 two sprays (before flowering and after fruit set), A5 two sprays (after fruit set and one month before harvest) A6, three sprays (before flowering, after fruit set, and one month before harvest) with the addition of ground fertilization according to the Fertilizer recommendation. The results of foliar fertilization showed a significant effect on the vegetative growth traits, as The treatment one month before harvest was superior to the rest of the treatments with a primary shoots length average 6.94 cm, while the control was 4.75 cm, while seaweed extract had a positive effect on the total number of flowers. Where the spraying treatment before flowering and after the fruit set contract was superior to the rest of the treatments, as the average number of flowers was 203.11 compared to the control with an average number of flowers 164.19, as well as in the percentage of fruit set, as the highest percentage of the contract when spraying treatment before flowering was 3.20% and in control 2.19% The results also showed a clear superiority in the productivity of the tree, especially the treatment before flowering and after the contract, Where the average tree productivity was 37.07 kg, and in the control it was 14.07 kg It was observed that there was a significant increase in the percentage of oil for the fruits, as a treatment a month before harvest was significantly superior to the rest of the treatments in both seasons, as the highest value of the oil percentage reached 20.28%, followed by a treatment before flowering, after fruit set and one month before harvest, with an oil percentage of 20.27 compared to the control 17.17%.

An experiment was conducted in a greenhouse growing tomato plant in sand nutrient
culture with variable ratios of Ca:Mg and potassium in the nutrient solution. The aim was
to evaluate productivity parameters and marketable fruit production. The exp
eriment
consisted of four Ca:Mg ratios (4:6, 5:5, 7.5:2.5, and 10:0.5 mM/L-1), along with three K
concentrations 0.5, 3, and 4.5 mM/L-1 in the nutrient solution. There were 12 treatment
each has three replicates.
In spite of the increase in weight and volume of fruits with increasing Ca:Mg ratios and
potassium concentrations, the increase in fruit number on the plant with increasing Ca:Mg
ratio to (5:5) and 6 mM K has the main effect on plant productivity and marketable fruits.
In this treatment plants produced 49 fruit/plant resulted from 5 fruit punches. Most of the
physiological disorder symptoms spread on fruits was blotchy shoulders, which was
associated directly with low potassium concentration in the growth medium, which
negatively influenced the marketable fruit production.
The research was conducted during the growing season in 2013-
2014 in Bssiren Hama. In a split- plot design: the varieties were
main plots (asgro, rama, Muncipal) and the sowing dates were subplots (15\11;30\11;15\12 and 30\12) and the densities we
re subplots (20 plant\m2, 13.33 plant\m2). The early planting went to Significant increase in the days to germination, long time of fruit; the number of days to flowering and the number of days to fruiting; Plant height; Number of branches plant ; weight of pod; number of pods plant; dressing percentage; Yield of green pods plant and
Yield of green pods. While the high density was observed
Significant increase in the Plant height; Number of branches plant;
weight of pod; number of pods plant; and Yield of green pods
plant, while the low density was observed Significant increase in the Yield of green pods. The Asgro variety was obtained at Rama and Muncipal varieties in the number of branches plant; number of pods; Yield of green pods plant and, while the Rama variety was obtained by the plant height, and non- significant results were found among varieties by the weight of pod. The positive results also showed in the interaction among factors.
Thirteen phenotypes of cultivated wild olive were selected during 2007- 2008
from four orchards in Mesiaf region, to study oil percentage and fatty acids
contents in these types for choosing types for oil production, in order to
propagate and cons
erve them in a germplasm, and then to be cultivated
because they have adapted to local climate in this region. The results were
analyzed statistically by using Gen-State program to calculate least significant
differences between values. The results confirmed the high biodiversity in these
studied types, and they were classified into five groups according to their oil
percentage and contents of oleic acid. The oil percentage ranged from 3.9 to
27.3 %, and the fatty acids had significant differences between them, the oleic
acid was in olive oil between 56.7 and 75.5%. The types P1-1 and p1-3 showed
the best results for producing oil.
The phenotypic characterizations, such as: fruit weight, seed weight and
dressing percentage for eighteen olive cultivars grown in Palmyra oasis were
studied and discriminated them qualitatively by studying their seeds and
processing their images
through fractal geometry technique during 2009 and
2010 seasons. The obtained data were analyzed statistically to have the least
significant difference by using Genstat 8th ed program, and the dissimilarity
matrix of these cultivars were included according to morphological and
geometrical features through SPSS program.
To know the effect of some fungicides on peacock eye disease has beentested five
fungicides from different chemical groups, using concentrations advisable to field
application,on the 45 year old olive trees in the Baksa village Lattakia . The resul
ts
showed an increase in incidence of the control of 22.4 to 45.5 % after 45 days, versus low
incidence rates in the fungicides tested treatments . The best two fungicides were
thiophanate –methyl with infection decreasing from 19.2 to 10.3% and chlorothalonil from
24.3% to 16.5% . The severity also decreased in the treatment of the fungicide thiophanate
–methyl from 9.7 to 4.1 % and chlorothalonil from 13.7 to 8.9 % while the severity of the
infection of the control increased from 10.5 to 25.6 % .In order to efficiency the fungicide
thiophanate – methyl was more effective reducing the infection severity compared with the
control with 82.8 %, followed by chlorothalonil , kresoxsim methyl , and mancozeb with
73.3 , 72.0 , 71.9% respectively whereas the fungicide copper oxychloride was the least
effective with 68.1%.
