هدفَ البحث إلى دراسة فعالية استخدام السقاية أو الرش الورقي بالمخصب العضوي أجروتـون فـي نمو شتول البندورة و في إنتاجية النباتات لأربعة أصـناف (Astona و Tyrad و E26 و Local) . نُفـذّت التجربة الحقلية في مزرعة أبي جرش التابعة لكلية الزراعة بجامعة دمشق. أظهرت النتائج أن معاملة الشتول بالمخصب العضوي أدت إلى زيادة في طول الشتلة، بلغت نحو 1.1 و 2.1 مرة في الصنف Astona ،و 2.1 و 3.1 مرة في الصنف E26 ، و بنحـو 1.1 و 2.1 فـي الـصنف Local ، و بنحو 1.1 و 2.1 في الصنف Tyrade في النباتات المعاملة بالمخصب سـقاية و رشـاً، علـى التوالي. كذلك بينت نتائج التحليل الإحصائي بين الأصناف، عدم وجود فرق معنوي في متوسـط ارتفـاع ساق الشتلة. إذْ كان أعلى طول لساق النبات في شاهد الصنف Astona حيث بلـغ 43.84±11.15 سـم في حين بلغ 36.70 ±05.12 سم في شاهد الصنف Local . كما أدت المعاملة بالمخصب العضوي إلى زيادة متفاوتة في معدل النمو بـالوزن الرطـب للمجمـوع الخضري. قُدرت بنحو 19 و 39 % للصنف Astona و بنحو 7 و 39 % للـصنف E26 و بنحـو 7 و 9 % للصنف Local و بنحو 0 و 20 % للصنف Tyrade ، في كل من المعاملـة بالـسقاية و الـرش الـورقي بالمخصب، على التوالي. كما أثرت المعاملة بالمواد الدبالية إيجابياً في إنتاجية النباتات، فقد ازداد متوسـط وزن الثمـرة فـي النباتات المعاملة بالمخصب سقايةً و رشاً. قُدرت بنحو 2.1 و 5.1 مرة في الصنف Astona ، و بنحـو 2.1 Tyrade الـصنف فـي 2 و 1.5 و بنحو Local الصنف في 2.3 و 2.2 و بنحو، E26 الصنف في 1.4 و على التوالي.
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, Tyrad, 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 search aims to study the efficiency of using“Biotolerance” as a
fertiliser; by a foliar spry on Pepper seedling. Four varieties were
used (Marcony, California wander, Maroty-7 andRobber). The
results showed that the treatment by the fertilizer resulted in an
increase in growth thorough the plant length increasing.
The experiment was carried out at Jableh region during 2012-2013 in two green
houses to study the effects of using the bumble bees and organic carbon to improve flower
set and yield of tomato hybrid Dalloula . The experiment included three treatmen
ts :
natural pollination (control) ,flowers pollination by organic carbon, and flowers pollination
by bumble bees . The first and second treatments were applied in the first green house , and
the third treatment was applied in the second green house . Results showed that the bumble
bees treatment produced significantly the highest percentage of flower set and yield than
the other treatments . Flower set of tomato over 10 clusters was 89.8% , 83.7% , 39.2% for
bumble bees treatment, organic carbon treatment, and control , respectively. The highest
yield (22 kg/m2)was obtained from bumble bees treatment . Flowers pollinated by bumble
bees gave fruits that looked better in shape , size and color ,and with higher weights . In
the bumble bee pollinated flowers , the quality of fruits was superior for vitamin C , sugar
and acidity .
The research aims to study the effect of certain organic and amino
compounds in the growth and production of tomato under green
houses conditions.Hulay F1 hybrid tomato and two organic
commercial vehicles differing in composition Hupost and
Boldo
uzerwere used.The experiment done in a way randomized
complete blocks designed , with three replicates per treatment , and
10 plants per replicate . Seedlings WERE Prepared in beet moss
using trays of Alstrepor inside the greenhouses.
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.
This research was conducted in plastic house in Zahed local for organic
agriculture in Tartous in two agriculture season during(2014-2015)
and(2015-2016) to study the effect of solid and liquid organic fertilizer from
digstate in some Physical and Chimical Characteristics of Tomato fruit
(hybride Nesma) in green house.
