This study was carried out during 2015to determine some chemical Composition
of the fruit of some distribution phenotypes of Prunus ursina in different regions of
Westrens of Syria.
six natural distribution sites were determined(Duerbsndiana-Alnab
een-Alshohtte-
Helata-Btmazah-Wadeheleen), and 35 trees were determined as samples.
Fruits were harvested and following parameters were determined: dry matter, total
acids (T.A), total soluble solids (T.S.S), and total sugar.
Statistical analysis of investigated phenotypes showed that There were differences
between dry matter, total soluble solids (T.S.S), and total sugar between two groups.
the trees were distributed in two groups (A, B) .The results showed existence of most
trees in whole sits, while (J6 and KA6) were distributed in two different sits(Btmazah and
Duerbsndiana) .
The research aims to study the effect of five harvesting wed (vegetative growth, the
beginning of open inflorescences flowering, the beginning of flowering, full bloom, and
completeness of the vegetative growth at the beginning of the month of Sept
ember and that
of plants that have already cutted), some of the morphological and productivity indicators
for common thyme Thymus vulgaris L . Experiment was designed by the complete
randomized manner in three replicates. Statistical analysis was performed by Anova test
using Genestat and account teams less moral LSD at a significance level of 5%. Results
showed superiority date mower fifth morally on the rest of the dates in terms of index
number of branches (16.50 branch / plant), productivity of the wet weight (55.00 g / plant),
productivity of dry matter (27.08 g / plant), while the superiority of the date of the second
mowing morally the rest of the appointments in terms of the percentage of essential oils
(size / weight) (2.10%), also reached the top of the plant at the time of his high mowing
fourth (21.50 cm).
Highlights the importance of the results by identifying the optimal harvesting date to
get the most fresh and dry weight of material and the highest percentage of essential oil,
and the resulting economic return to the farmer healthy and beneficial to the consumer,
with the continued preservation of the existence of the plant and its tender.
The present study aimed to evaluate the productinty status of panicum
turgidum (Thumam) under the environmental conditions of the eastern
province of Kingdom of Saudi Arabia. Forty eight experimental sites (each of
25 m2, i.e. 1*25 m) were randoml
y selected from three locations (Roads of
Riyadh, Ogair and Damam), which represent the micro-environment of
thumam. Obtained results showed that the dominated plant species associated
with thumam were Eragrostis barrelieri, Haloxylon salicornicum, Leptadenia
pyrotechnica, Plantago ovata and Zygophyllum coccineum. The forage
production of thumam was 57 kg dry matter/ha. However, the nutrient value of
it was relatively low due to the low protein content (4.2 %) and high crude fiber
(30.2 %). Moreover, neutral detergent fiber was 62.4 %, acid detergent fiber
was 65.4 % and lignin was 11.70 % which indicate low nutritional forage value,
compared with traditional forage crops, i.e. Rhodesgrass (Chloris gayana) and
Alfalfa ( Medicago sativa). Macronutrient contents (Na, K, Ca and Mg) were in
the range of sheep and camel requirements, while P was very low as well as
micronutrients (Zn, Cu and Mn).

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.
