This research was conducted in the countryside of Tartous, to aim for the analysis of moisture, protein, TSS and pH of royal jelly (RJ) harvested after 24 to 48 hours of grafting, compared with that traditionally harvested after 72 hours of grafting.
As well as to analysis of these compounds in (RJ) within cells to brood of workers, compared with the (RJ) product in cups. 50 samples were analyzed in wet weight and dry weight for (RJ), which was harvested in this research.
The lack of information about the cultivation of coriander plant in Syria prompted us
to study the effect of four plant densities (33.33،10، 13.33 and 20 plant/m2)، and four levels
of phosphate fertilization (0107.2،160.8، and 214.4 of Superphospha
te 46%) on some
productive and quality traits of the coriander plant. This study was carried out in Tartous
province during the growing season 2014، using Randomized Complete Block design with
a Split Plot arrangement of treatments. The Results revealed that there were significant
differences between the treatments for the whole traits، in addition to a significant
interaction between density and phosphate fertilization. Although the densities (10، 13.33
and 20 plant/m2) varied in their effect، they had superiority upon the
control(33،33)plant/m2، and the density 10 plant/m2 had more important effect in terms of
increasing each of: branches number/plant، seed weight/plant، seeds number/inflorescence،
protein content in plants and seeds and beta carotene and chlorophyll. However، the level
160.8k.g/h of P2O5 increased the number of inflorescences/plant، number of fruits/plant
and seed weight/ inflorescence.
Terebinth trees have been occupying a good part of the mount of Syrian
(abed elaziz, pelass). The Pistacia atlantica fruit, rich in oil, is used by local
inhabitants in many ways, few studies investigation of the P. atlantica fruit oil
of Syria ha
s been carried out,This study investigates the protein, ash, crude oil
and oil composition of P. atlantica with respect to total phenol, iodine value and
saponification value, in order to classify it among the other known edible oils
thenafter compare the oil composition with the oils of other Pistacia species.
The fruit of P.atlantica appears to be rich in oil. The major fatty acid in the
sample studied are oleic, linoleic, our results show that. The oil has a higher
content of unsaturated FA (oleic + linoleic = 72%). The oil can be classified as
an oleo-linoleic vegetable oil. The biochemical data showed an elevated MUFA
content (50-48%) which may constitute an important property against certain
pathologies for its nutritional and preventive virtues.
Objective of this work was to investigate how plant density and nitrogen
rate affects the growth , yield and its components in maize (Bassel 2 hybrid).
The experiment was carried out, at the agricultural research centre in Snoubar
Jableh, during t
he 2008 and 2009 seasons, included 12 treatments which were
the combination three plant population densities 71428/ha, 57142/ha, and
47619/ha and four N rates (0, 60, 120 and 180 kg/ha). The experimental design
was a split-plot, with different densities as main plots, randomized in three
complete blocks, and the fertilization as subplots. The data were analyzed by
using “Mstat” statistical package. Increasing planting population density
delayed anthesis and silking date, increased the anthesis-silking interval, plant
height, ear height, grain yield, agronomic nitrogen efficiency and nitrogen use
efficiency, but decreased ear leaf area, chlorophyll content, 1000 seed weight,
number of grains/ear, shelling percentage (%), and grain protein content.
Nitrogen fertilizer decreased tassilling and silking date, and nitrogen use
efficiency, increasing plant and ear height, ear leaf area, chlorophyll content,
number of grains/ear, ear weight,1000-grains weight, Shelling percentage,
grain yield up to 120 kg N/ha, agronomic nitrogen efficiency and grain protein
content.
During the season of 2002, samples of olive fruit were taken (Ashrasi type)
from Ninavah horticulture’s station that belongs to the ministry of agriculture
in Iraq. The purpose of this research is to study some physical and chemical
characteristic
s during the growing period, from July until October. Those
characteristics include moisture, ash, oil content, chlorophyll A & B, protein,
pH and carbohydrate, In addition to fruit length, size, weight, radius, and
rigidity. The results showed significant increase in moisture, oil, weight, size
and length of the fruit were studied. Significant reduction was noticed in the
percentages of the protein, carbohydrate, ash and the fruit rigidity. The highest
values of chlorophyll were observed during The month of September. October
considered as the best time to harvest olive fruits for pickle purpose.
