نفذ البحث خلال الموسم الزراعي 2012- 2013 ( موسم طويل ) ضمن بيتين بلاستيكيين في منطقة جبلة لدراسة تأثير استخدام النحل الطنان و الكربون العضوي في تحسين نسبة عقد الثمار و زيادة الإنتاجية لهجين البندورة دلولة, تضمنت التجربة ثلاث معاملات هي تلقيح طبيعي (شاهد) , رش الأزهار بالكربون العضوي, تلقيح الأزهار باستخدام النحل الطنان , نفذت المعاملتين الأولى و الثانية في بيت بلاستيكي واحد ,أما المعاملة الثالثة فنفذت في بيت بلاستيكي ثاني , و قد أظهرت النتائج تفوق معاملة النحل الطنان بفروق معنوية على معاملتي الكربون العضوي و الشاهد من حيث نسبة عقد الثمار و كمية الإنتاج , حيث بلغت نسبة عقد الثمار للنورات الزهرية العشرة الأولى 89.8% و 83.7% و 39.2% لمعاملات النحل الطنان و الكربون العضوي و الشاهد على التوالي . كما أعطت معاملة النحل الطنان أعلى إنتاجية (22 كغ/م2), و كانت الثمار المنتجة في معاملة النحل الطنان أكبر وزنا و أكثر تجانسا في الشكل و الحجم و اللون و ذات نوعية أفضل من حيث محتواها من فيتامين C و السكريات و الحموضة .
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 treatments : 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 .

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 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.
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.
This research aimsto study the effect of single and mixed infection of Potato Y Virus (PVY) and Cucumber mosaic virus(CMV) on the number of leaves, number of branches, plant height and stem circumference of tomato plants (cv.Elegro and Local). The ex
periment was carried out in 2012 in a greenhouse in Tartous. Results show that the interactions in both varieties to virus infections are different. The mixed infections cause slight and weak effects compared to single infections. This is probably due to the antagonistic relationship between Potato Y virus and Cucumber mosaic virus and their effects on mean number of leaves, mean number of branches, mean height of plants, and mean stem circumference. Tomato plants' stems were (Elegro 106.42, 16.75, 103.58 cm, 4.84cm.; Local 94.42,15, 87.17 cm, 4.59 cm, respectively). Consequently, the timing of mixed infection playsarole in appearance, development and effect on other viruses.
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.
