نفذت التجربة في كلية الزراعة-جامعة دمشق في الموسم الزراعي 2012-2013 لدراسة تأثير الرش الورقي بمستخلص أعشاب البحر بتركيز 5 و 10 غ/ل، و حمـض الجبريليـك (GA3) بتركيـز 50 و 100 ppm في نمو البصل البلدي الأحمر و إنتاجه عند مستويات ري مختلفة (100 و 75 و 50 % من الـسعة الحقلية). زرعت أبصال القزح في أصص بلاستيكية، و رشت النباتات عند وصـولها لمرحلـة 3-4 أوراق بمعاملات الرش الورقي بمعدل مرة كل أسبوعين حتى اكتمال النمو الخضري.
Yhis study was investigated at Agriculture Faculty of Damascus university during the agricultural season of 2012/2013 in order to determine the effect of foliar spray with seaweed extract (5 and 10 g/l) and GA3 (50 and 100 ppm) on the growth and production of local red onion (Baladi) at different levels of irrigation (100, 75, and 50% of field capacity). Onion bulblets were planted in pots and plants were treated when they had 3-4 leaves and every two weeks until full vegetative growth.

استخدم التسميد الورقي بمستخلص الأعشاب البحرية والخميرة والحديد المخلب بالأحماض الأمينية لتحسين بعض الصفات الفيزيولوجية والإنتاجية لشجرة الدراق صنف red heaven والتخفيف من ظاهرتي إزدواجية ثمار الدراق وإصفرار نقص الحديد.
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.
A study was carried out in the 2nd agro-ecological zone at the General Commission
for Scientific Agricultural Research/Sirbaya Research Station/Aleppo during the growing
season 2011-2012. The study aimed at evaluating the response of different vari
eties of
lentil to supplemental irrigation. The experiment adopted a split plot design with three
replicates. Two water treatments, supplemental irrigation (R) and rain feed (Ro) were
applied to three varieties of lentil: IDLEB1 (D1), IDLEB1 (D2), and IDLEB1 (D3). The
results showed that R was more significant than Ro at a confidence level 5% for grain, hay
yield, and 100-grain weight. The differences were significant between the varieties that
applied Ro; the most significant of which was D3 for grain and hay yield, and D2 for 100-
grain weight. As for R, the differences were significant for grain yield (the most significant
was D3) and 100-grain weight (the most significant was D2), while there was no
significant difference for hay yield. There was no interaction between water treatment and
the variety in terms of grain yield and 100-grain weight, while it was observed for hay
yield.
The research was carried out in Nawa area in Daraa governorate during
the year 2012, to study the response of four sesame genotypes (Local Idleb,
Zouri, Improved Hourani and Brown Sudani) to four irrigation treatments
(rainfed cultivation, one sup
plemental irrigation during branches formation,
two supplemental irrigations during branche and capsules formation and three
supplemental irrigations during branches formation, capsules formation and
seed filling stages). The experiment was laid out in split plot design with three
replications. The statistical analysis clearly indicated to the existence of genetic
variation in (p < 0.05) the response of the studied sesame genotypes to applied
irrigation treatments. The genotype Local Idleb recorded significantly the
highest values of all investigated traits and the heighest seed yield (3.45 t. ha-1)
as compared to other studied genotypes. Providing sesame crop with three
irrigations surpassed in all investigated traits and recorded the highest seed
yield (3.79 t.ha-1). It was recommended to provide sesame crop with three
irrigations during critical stages (branches formation, capsules formation and
seed filling).
The experiment was conducted during 1998 and 1999 seasons in the field of
the left bank of Euphrate river at the Ramadi town. The soil texture was sandy
loam and loam, using peanut (Arachis hypogaea L.) local variety (semi-erect).
The objective wa
s to investigate the optimum spacing between the rows (50, 75,
100 cm) and within the rows (20, 35, 50 cm), using factorial experiment within
randomized complete block design with three replications.
