استهدفت هذه الدراسة تقييم الحالة الإنتاجية لنبات الثمام النامي طبيعيًا بمراعي المنطقة الشرقية من المملكة العربية السعودية، إذ تم اختيار 48 موقعًا تجريبيًا (مساحة كل موقع 25 م 2، أبعاده 1X25 مترًا) أخذت بطريقة عشوائية في ثلاث مناطق ( الرياض، العقير، الدمام) تمثل البيئة المناسبة لنباتات الثمام.أظهرت النتائج أن الأنواع النباتية المنتجة التي رافقت نبات الثمام كانت Eragrostis barrelieri, Haloxylon salicornicum, Leptadenia pyrotechnica,Plantago ovata, Zygophyllum coccineum.
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 randomly 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 present study aimed to evaluate the ecological and phytosociological
status of panicum turgidum under the environmental conditions of the eastern
province of Kingdom of Saudi Arabia. 48 stands (each of 25 m2, i.e. 1x25 m)
were randomly selecte
d from three locations (Riyadh, Ogair and Damam)
which represent the optimum habitat of P. turgidum. The obtained results
showed that the dominated plant species associated with P. turgidum were
Cyperus conglomertus, Eragrostis barrelieri, Haloxylon persicum, Haloxylon
salicornicum, Heliotropium bocciferum, Launaea mucronata, Leptadenia
pyrotechnica, Monsonia nevia and Plantago ovata. P. turgidum, and is
recommended as an important grazing vegetation in deep sand soil. Soil salinity
(ECe), soil PH, CaCO3, organic matter, soil texture (Sand %) and soil moisture
(FC) were the most limiting soil properties affecting P. turgidum distribution
naturally at the studied area.
The research was conducted at the Forestry Nursery of the Directorate
of Agriculture in Deir Ezzor Governorate during the growing season of
2019. The objective of the study was to study the effect of humic acid
application and different irrigation
intervals on chemical composition of
blue panic plant (Panicum antidotale). The experiment was implemented in
a Randomized Complete Block Design (RCBD) by planting Panicum seeds
in polyethylene bags filled with 2 soils to 1 sand mixture in four replicates.
Whereas three irrigation intervals (7, 14, and 21 days) and two humic acid
application treatments (control without addition and application of humic
acid) were used. Fresh plant sample from each treatment was taken at each
cut, and samples were dried at 70C
until weight was stable. Chmeical
compostion was conducted for the samples and dry matter %, crude protein
%, crude fiber %, total carbohydrate %, and ether extract % were estimated
according the the common methods. The results showed that the control
treatment (irrigation every 7 days) was significantly superior to the two
irrigation treatments every 14 days and 21 days in the percentage of soliable
carbohydrates (42.09%). While, irrigation treatment every 14 days
outperformed the other irrigation treatments and recorded the highest values
of percentage of crude protein (17.07%) and the percentage of ether extract (2.73%). The irrigation treatment every 21 days gave the highest values of
ash percentage (16.38%). No significant differences were recorded between
the irrigation treatments for the percentage of dry matter and the percentage
of crude fiber. The control treatment of humic acid outperformed the
addition of humic acid interms of the percentage of crude fiber (CF), while
the treatment of addition of humic acid outperformed the control in the
percentages of crude protein (CP), ash and ether extract (EE). No significant
differences were recorded between the application and control of humic acid
treatments in dry matter % and the percentage of soluble carbohydrates. The
effect of the interaction between irrigation intervals and the application of
humic acid was significant for all the studied characteristics. The control
treatment (irrigation every 7 days) with the addition of humic acid recorded
the highest values for the percentage of soluble carbohydrates (42.92%).
The irrigation treatment every 14 days with the addition of humic acid gave
the highest values in the percentage of crude protein (17.81%), the
percentage of ash (16.55%) and the percentage of extracted ether (2.81%).
As for the irrigation treatment every 21 days with the addition of humic
acid, had the highest values for the percentage of dry matter (96.25%)
This study aims to construct a mathematical model to calculate the form factor of
Palestine Oak Maquis grown on the eastern versants of coastal mountains. The form factor
model can help foresters to precisely estimate the volume of tree and forest
stands.
In the year 2014, 129 oak shoots of various ages and sizes, located in natural stands
of different densities and site qualities covering all conditions of region grown on, were
felled.
Diameters at different heights of the felled shoots were measured; shoots volumes
and volumes of equivalent cylinders were calculated, and consequently the values of shoot
form factor were computed. The dataset was randomly split into two parts, 70% (90
shoots) of the data for constructing form factor model and 30% (39 trees) for model
validation.
Several form factor models were developed using the non-linear regression equations
in the statistical program SPSS. Best fit to the data was selected and value of the
coefficient of determination adjusted (R²adj) was about 0.77. The model has been validated
using several statistical methods, the relative bias of the best model ( e%) was ca. -3.6 %,
while the value of model accuracy ) % x m ) was 15%. In order to obtain lower value of
model relative bias and higher value of accuracy, it’s recommended to use a larger
database comprising all distribution areas of oak Maquis in Syria.
This study aimed at investigating the image of women in Arabic
language and social studies textbooks of primary and middle stages
through the roles of women, the different social aspects and social status
presented in the textbooks of Arabic langu
age and social studies.
This investigation was carried out at the experimental Station of the College
of Agriculture and Veterinary Medicine, King Saud University, Al-Qassim,
Saudi Arabia, during the growing season 2001/2002. The objectives of the
research were to study
and evaluate the productivity, morphological and
physiological behavior of alfalfa (Medicago sativa L.) plants grown under palm
trees environment.
The results proved the important effects of palm trees shading on alfalfa
growth, development and productivity. Significant differences were observed
between the control treatment and the two other treatments. The results also
showed a significant increase in fresh and dry weight and quality
characteristics except for fat percentage. This percentage increased gradually
from treatment 1, which was located under palm trees, to treatment 2, which
was located between palm trees to the control treatment, which was located
away from palm trees, where there was no shading. The morphological and
physiological characteristics did not significantly change in spite of the existed
changes among their means.
