نُفذ البحث في المنطقة الساحلية، و بيّنت النتائج الآتي: تّجرى عمليات خدمة التربة لبساتين الحمضيات الحديثة و المتوسطة العمر، و لا تُجرى في البساتين المعمرة (أكثر من 30 سنة)، و تتمثل هذه العمليات بالعزيق (الفلاحة السطحية)، و لم نلحظ استخدام المحاريث إلّا في البساتين حديثة الزراعة (بعمر أقل من 12 سنة) بهدف تهيئة التربة لزراعة بعض المحاصيل بين صفوف الأشجار. أثرت المحاريث المستخدمة بشكل مختلف في أشجار الحمضيات حسب عمق الفلاحة و نوع الآلة المستخدمة، فقد ظهرت بعض الجذور على سطح التربة المعاملة باستخدام المشط القرصي على عمق (8) سم، بينما اقتلعت بعض الجذور و قطع بعضها الآخر عند استخدام المحراث الحفار على عمق (20) سم. و عند استخدام المحراث المطرحي على عمق (30) سم كان التأثير أكثر وضوحاً، إذ تضررت غالبية الجذور في المنطقة المعاملة.
The research was carried out during the years 2010 and 2011. The results showed the following: The soil's care operations are carried out in the modern and middle old orange fields and aren't carried out in the old fields ( more than 30 years). The operations are embodied in the cultivating operation (facial plowing). The plows are used only in the modern fields to prepare the seed bed for planting some plants (agronomists) between the trees classes. The used plows were effected differently on the orange trees according to plowing depth and machine sorts. By using the disk harrows with (8) cm depth appeared some roots on the soil's surface. The trees roots were uprooted and cut up by using the chisel plow with (20) cm depth and by using the mould board plough with (30) cm depth, but the effect was so clear by using the mould board plough, that the most of the roots were hurt.

Effect of Citrus trestiza virus (CTV) in Growth of Balady common orange and
Satsuma trees grafted on sour orange Rootstock in Hraisoon during 2013 was studied. The
results showed that of infection by CTV caused deformation of shaped leaves, boat or
spoon-shaped leaves. The symptoms was greater in Satsuma from Balady common orange
trees. Also leaf size average of Balady common orange trees reduced from 15.58 cm2 in
healthy trees to 11.82 cm2 in infection trees as percentage 24.13, and from 19.64 cm2 in
healthy Satsuma trees to 12.38 cm2 in infection trees as percentage 36.97. and length
average of spring, summery and autumnal fresh foliages growths was reduced from 20.98
cm, 14.62 cm, 12.17cm in healthy Balady common orange trees to18.75cm, 12.52cm, 9.32
cm in infection trees respectively. Also it reduced from 18.78 cm, 14.56 cm, 10.06 cm in
healthy Satsuma trees to 13.78 cm, 9.34 cm, 6.03 cm in infection trees respectively, the
CTV had no significant effect on Trunk circumference in both varieties.
The research aims to study the differences of some aspects of physiological
activities in three ornamental plants, Conocarpus erectus L., Hibiscus rosasinensis
L, and Vinca rosea L. grown in Makkah. These plants are founded in
similar environmenta
l circumstances (drought and rewatering). Through
studying and comparing: Photosynthetic activity, maximal productivity,
strategies of drought tolerance, transpiration and hardening. Determining of
the most suitable environmental and agricultural conditions of each plant
species mentioned above have been achieved.
International trade contracts are considered one of the most important topics of international law, because they are reflected on the economies of all countries, and that they are of the successive contracts, where goods take time to cross the border
s of more than one country, which makes them exposed to risks. And since the documentary credit is one of the international trade contracts for its role in providing guarantee for the international sales, It is also one of the most capable means that the modern era has known in contributing to the completion of international trade deals, one the most important banking operations in the world, one of the most used tools of payment in international trade, and for its success as a fast-performing and low-cost tool, and since the documentary credit contract has a number of stages until it reaches its goal, this process may be hampered by unexpected events that are independent of the will of the debtor and affect the implementation making it either impossible as force majeure, or exhausting for debtor while remaining possible; as emergency circumstance.
The study was conducted in 2011 on 6-years-old citrus trees "Washington navel
141". It contained four treatments with three replicates for each treatment. The results
showed that:
The wastewater treatments showed superiority on the control in the
number of
vegetative growth and its length.
The number of inflorescence buds, was increased in the second treatment (irrigation
with 50% treated wastewater +50% normal water) (5. 37) which dominated the other
treatments.
The weight of fruit was affected by treated wastewater irrigation. Second treatment
(irrigation with 50%treated wastewater+50 % normal water) was better than the control
treatment. It was increased by (308. 3 g) compared to (259. 5 g) for the control treatment.
Fruit yield production per tree, was increased by second treatment (irrigation with
50% treated wastewater+50 % normal water) (28. 9kg) compared to (15. 3kg) for the
control.
Treated wastewater irrigation had positive effects in the quality of fruit
(Total sugar %), (T. S. S %) and the coefficient of maturity were increased in second and
third treatment compared to other treatments, while (T. A %) was decreased in all
wastewater treatments.
Total productive maintenance (TPM) for the time being is of great
importance in Investment Projects, for the need to preserve the
physical assets and continuity of work.
