نفذ البحث على أشجار زيتون Oleaeuropaea L بعمر 15 عاماً من الصنفين الصوراني و القيسي، مزروعة في المنطقة الغربية من حمص في تربة بازلتية فقيرة بالمادة العضوية و بعنصر البوتاسيوم، و ذلك بهدف البحث إلى دراسة تأثير إضافة كميات مختلفة من السماد العضوي و السماد البوتاسي في الإنتاج، و وزن الثمرة، و نسبة الزيت، ورقم حموضته. بينت النتائج أن أعلى قيمة للإنتاج و وزن الثمرة و نسبة الزيت تحققت عند إضافة السماد العضوي مع البوتاسي. ازداد رقم الحموضة في معاملات التسميد العضوي مع التسميد البوتاسي و لكن بقي ضمن حدود الزيت البكر الأول (أقل من 2%). ، و كان في معاملات التسميد البوتاسي و معاملات التسميد العضوي أقل من 1% و بذلك يكون زيتاً بكرًا ممتازًا.
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 study was conducted in Abu-Jarash farm at the Faculty of Agriculture,
Damascus University during the main season 2013 to evaluate the effect of soil
solarization and organic fertilization treatments on the productivity of some
maize genotypes
(Basel 1, Basel 2, Ghouta 1, Ghouta 82 and Local White). The
experiment was laid out according to split-split plot design with three
replications. The statistical analysis results clearly indicated to the existence of
variability in the response of studied maize genotypes to soil solarization and
organic fertilization treatments. The genotype Ghouta 82 surpassed in the traits
of plant height, leaf area index, 100-kernel weight and grain yield (150.25 cm,
2.84, 28.10 g and 7.99 ton.ha-1) respectively, as compared to other studied
genotypes and was closely followed by the genotype Basel 2 which recorded the
highest number of rows per ear (13.83 row/ear). Soil solarization for 45 days
before sowing and applying organic manures at the rate of 20 ton.ha-1
encouraged the traits of plant height, leaf area index, number of rows and
grains per ear, 100-kernel weight which was reflected on grain yield. Therefore
we can grow variety Ghouta 82 or hybrid Basel 2 to get higher yield of maize.
The research was carried out at Jeb Ramlah Research Station – AlGhab Research Center -
General Authority of Scientific Agricultural Research at 2017 growing season. The
objective was to investigate the effect of three organic and bio fertilizers (B
acillus, Humic
acid and Amino acids) and three fertilization methods (Soaking seeds, Vegetative spraying
and Plant irrigation) in some morphological and production traits of cotton cultivar 124
(Gossypium herutum L.) The experiment was conducted according to RCBD with three
replications. The first factor (fertilizer type) occupied the main plots, while the second
factor (fertilization method) occupied the split plots. Statistical analysis was carried out
using the Genestat.12 software and the least significant difference L.S.D. at 5% level was
calculated. Studied traits included (at the beginning of Blooming stage): Plant Height,
Plant wet weight, Plant dry weight, Leaf area and plant production of cotton. The results
showed that the average of treatment of amino acids was superiority significant on the
others in terms of plant height (70.70cm), Plant wet and dry weight (201.50, and 83.41g),
respectively, Leaf area (4240.15cm2/plant) and plant production of cotton (75.13g). For
fertilization method, Vegetative spraying average was superiority significant on the others
in terms of all studied traits.
A field experiment was carried out to investigate the effects of organic
fertilizers (mushroom substrate residues, poultry manure and city compost)
and mineral fertilizers (NPK) on some properties and productivity of a
calcareous soil using chard
(Beta vulgaris) as a test crop. The plant was
cultivated at spring season 2009. The first cut was after 60 days of swing. The
results of experiment were: The NPK fertilizer significantly affected dry weight
of plant yield (157.6g/m2soil) and the efficiency of fertilizer in productivity was
50.8% compare to control (104.5g/m2soil). The treatment of 50% NPK + 50%
poultry manure gave the highest yeld compare to other treatments. However
the organic treatments did not differ significantly among them. Concentrations
of NPK nutrients in plant leaves were as follows: NPK > 50% NPK + 50%
poultry manure > poultry manure > 50% NPK + 50% mushroom substrate >
mushroom substrate > 50% NPK + 50% city compost > city compost. The
organic fertilizers decreased the NPK in plant and soil compare with NPK
fertilizer treatment. However there was no significant differences between NPK
treatment yield and 50% NPK + 50 % poultry manure treatment. It was
concluded that the use of 50% NPK +50 % orgnic fertilizer (specially poultry
manure) was important to get best result.
