هدف البحث إلى دراسة تأثير التغذية بالمخصب العضوي في نمو نباتـات الفاصـولياء و إنتاجيتهـا، و استخدم من أجل ذلك صنف الفاصولياء تيما (محدود النمو) و المخصب العضوي "هيومـاكس" بطريقتـي التغذية الجذرية و الورقية بتركيز (2 و4غ/ل) بمعدل ثلاث مرات و ذلك بعد أسبوعين من الإنبـات و بفـارق أسبوعين بين المعاملة و الأخرى، وفق تصميم القطاعات العشوائية البسيطة، و نُفِذت التجربة فـي أواخـر شهر نيسان عام 2013 في مزرعة "أبي جرش- كلية الزراعة- جامعة دمشق. أظهرت النتائج أن التغذيـة بالمخصب العضوي أدت إلى زيادة في النمو و الإنتاجية، و تفوقت طريقة التغذية الورقيـة بالمقارنـة مـع التغذية الجذرية بالنسبة لبعض المؤشرات كالوزن الجاف للنبات (89.6 غ)، مـساحة المـسطح الـورقي سم2 (4595.44)، دليل المسطح الورقي (55.2 ) , عدد النورات الزهرية (3.15 نورة/نبات)، عدد القـرون (6.29 قرن/نبات)، و إنتاج النبات (9.156 غ/نبات)، مع عدم وجود أي فرق معنوي بين التركيزين.
The experiment was carried out at the end of April during 2013 In Abi- Jarash farm, Faculty of Agriculture, Damascus University in order to determine the influence of organic fertilization on the growth and yield of Snap bean. The snap bean ”Tema” Phaseolus Varity, and organic fertilizer” Humax” with two methods (root application and foliar spry) and two concentrations (2 and 4 g/L) were used. The organic fertilizer was used after two weeks of germination and then two weeks between treatment and another and the experiment was laid according to simple randomized block design. Results showed that organic fertilizer caused an increase of plants growth and yield, and the foliar spray method showed significant superiority (p<0.05) to some of the studied parameter such as plant dry weight (6.89 g), leaf area (4595.44 cm2), leaf area index (2.55), number of clusters (15.3 cluster/ plant), number of pods (29.6 pod/plant), plant yield (156.9 g/plant), compared to the root applied method. Results also showed no significant effect for the fertilizer concentration.

Research summary
هدفت هذه الدراسة إلى تقييم تأثير استخدام المخصب العضوي "هيوماكس" على نمو وإنتاجية نبات الفاصولياء (Phaseolus vulgaris L.). أجريت التجربة في مزرعة أبي جرش التابعة لكلية الزراعة بجامعة دمشق في أبريل 2013. استخدم صنف الفاصولياء "تيما" وتم تطبيق المخصب العضوي بطريقتين: التغذية الجذرية والتغذية الورقية، وبتركيزين مختلفين (2 و4 غ/ل). أظهرت النتائج أن التغذية بالمخصب العضوي أدت إلى زيادة في النمو والإنتاجية، حيث تفوقت طريقة التغذية الورقية على التغذية الجذرية في عدة مؤشرات مثل الوزن الجاف للنبات، مساحة المسطح الورقي، عدد النورات الزهرية، وعدد القرون. لم يكن هناك فرق معنوي بين التركيزين المستخدمين. توصي الدراسة باستخدام المخصب العضوي بطريقة التغذية الورقية وبتركيز منخفض لتعزيز نمو وإنتاجية نبات الفاصولياء.
Critical review
دراسة نقدية: تعتبر هذه الدراسة مهمة لأنها تقدم دليلاً على فعالية المخصب العضوي "هيوماكس" في تحسين نمو وإنتاجية نبات الفاصولياء. ومع ذلك، هناك بعض النقاط التي يمكن تحسينها. أولاً، كان من الأفضل تضمين مجموعة أوسع من التراكيز لتحديد التركيز الأمثل بشكل أكثر دقة. ثانياً، لم يتم تناول تأثير المخصب العضوي على جودة الفاصولياء المنتجة، وهو جانب مهم يجب دراسته. أخيراً، كان من الممكن تحسين تصميم التجربة بإضافة مكررات أكثر لضمان دقة النتائج وتقليل التباين.

The research was carried out during two season 2012/2013 –
2013/2014 in Eh-Shikh Barder area. To study the effect of mineral
and cows organic manure on quality of leaves Syrian thyme
(Thymus vulgaris L.) plant.
This search was carried out in Abi Garash farm, Faculty of Agriculture,
Damascus University to study the efficiency of using “Agerton” as a fertiliser;
either by irrigation or a foliar spry on tomato seedling. Four varieties were
used (Astona, Tyr
ad, E26 and Local).
Results showed that the treatment by the fertilizer resulted in an increase in
growth thorough the plant length increasing. This increase was about 1.1 and
1.2 folds for all varieties and types of treatment (irrigation and foliar spry), as
compared to the control.
Moreover, the using of fertilizer led to a significant increase in the yield of
plant, which increased by 1.2 and 1.5 in Astona; 1.2 and 1.4 in E26, 2.2 and 2.3
in Local and 1.5 and 2 in Tyrade, for the treatment of irrigation and foliar spry,
respectively.
This research aims to study the effect of different treatments of potato plants with a
feeding organ on the growth and yield of potato crop and on the quality of tubers. The
Romano variety of potato was used, and the commercial organic feeder "plan
t energy
1000" was applied in four treatments. The treatments were: a control and three ways for
treating the plants with the organic feeder: by roots, foliage spray, and by both in one
treatment.
The completely randomized design was adopted in this experiment. The experiment
was implemented in the nursery farm of Tishreen University in the spring planting season
of 2012.
The results showed that treating potato plants with the organic feeder led in general
to an increase in the growth, which was reflected in the increase in the fresh weight, total
leaf area and its indication, as well as in the quality and number of tubers, total production
and marketing quality. These results were clearer in the case of the joint treatment: root
feeding and foliage spray together. This treatment showed significant superiority in
increasing production and improving its quality.
A field experiment was carried out in Hout research station- Agriculture research center in
Swaida – General Commission For Scientific Research Agricultural during the growing
season of 2015-2016 to study the effect of different levels of deficit i
rrigation with
different levels of town refuse compost (TRC)on some morphological parameters and the
productivity of lettuce and compare it with the common mineral fertilizers.
The experiment was designed as a split block design with three levels of irrigation, each
level has four fertilizing treatments and control with three replicates.
The research has studied the plant height (H), the number of its leaves (N) ,the leaf area
(LAL), the plant's leaves area (LAP), the leaves area index (LAI), in addition to the lettuce
head's fresh weight and the total productivity of the planted area.
The irrigation and fertilizing interaction results indicate to the obvious positive effect of
the organic additions on the productivity parameters and the efficiency of deficit irrigation,
and the significant superiority of T11 treatment in all of the measured parameters in
compare with the other treatments with an increased final yield of %169 comparing with
T15 and % 428 comparing with T35.
The results also indicate to the possibility of saving %25 of the consumed amount of
irrigation water by using TRC instead of mineral fertilizer , and reveal that the organicmineral
combination achieved a better yield with percentages of ( 29- 44 – 53 )%
comparing with single mineral fertilizer in the three studied irrigation levels (T1-T2-T3)
respectively.
These results give the farmer a wide range of possibilities to choose what suits his
available productivity needs , and a clear idea about the expected yield according to the
chosen treatment.
The experiment was performed at Agricultural Research Center in Jousiyet
Al-Kharab in Al-Qsair district, Homs governorate during the 2010-2011 season
to investigate the effect of planting depth and organic acids on saffron growth
and productivity.
Four treatments including amino acids, amino Humic,
mixture of them in addition to the control were applied. Each treatment was
comprised of three planting depths (10, 15 and 20 cm). Results showed that by
increasing planting depth up to 20 cm a significant reduction had resulted in
the percentage of rooted plants and number of shoots while there were no
significant differences between the two depths 10 vs. 15 cm. The number of
leaves and their length were not affected significantly with the increasing of
planting depths. The number of flower, wet and dry weights of the stigmas
were increased significantly with the increase of planting depth from 10 to
15 cm. The application of the humic acids had significant superiority overall
the other applications in rooted plant percentage, number of shoots, number of
flowers and the dry and wet weights of the stigmas, while the application of the
mixture came in the second rank in number of flowers and the dry and wet
weights of the stigmas. However, no significant differences were occurred
between the control and application of amino acids. The highest percentage of
rooted plants was observed in applying humic acids in all depths and the
percentage of rooted plants reached 100%. The highest number of flowers,
highest stigmas wet and dry weights were observed with the interaction
between applying humic acids at 15 cm depth. The highest number of shoots
and number of leaves appeared with the interaction between 20 cm depth and
humic acids treatment, the longist leaves were appeared with the interaction
between amino acids and 15 cm depth.
