This search was conducted in Albassa town at Lattakia governorate , during 2011
and 2012 growing seasons for study effects of 3 sowing dates ( 15th of April , 25th of April
and 5th of May ) and 4 levels of nitrogen fertilization ( N1: control , N2:
50 kg/ha , N3: 100
kg/ha , N4: 150 kg/ha ) on several attributes of groundnut (Coastal category) production .
The results showed that the 5th of May sowing date had significant excel in the
average of the two growing seasons in dry weight of pods in plant , wheight 100- Seeds,
The per-hectare yield of seeds and Harvest index , It ranked first in the two seasons search.
Also, The application of nitrogen fertilizer at a rate of 150 kg/ha had resulted in a
significant increase in studied productivity traits in the average of the two growing
seasons , Except for harvest index , which was at least as compared to other levels of
fertilization.
The interaction between the sowing date ( 5th of May ) and the level of nitrogen
fertilization (150 kg/ha) showed a significant excel in the average of the two growing
seasons in dry weight of pods in plant , wheight 100- Seeds and The per-hectare yield of
seeds .
This search was carried out in the farm of faculty of Agriculture-
Damascus during 2012-2013 to determine the adaption of five
Safflower genotypes) Farming conditions in the lug
intensive in the province of Damascus under the effect of different
nitrogen fertilizers and witness without fertilization N3 . And how they affected safflower
accessions morphological traits and productivity.
This study was carried out during the growing season of 2015
to study effect od three planting date (1 Feb., 15 Feb. and 1
March) and four levels of nitrogen fertilization (0, 40, 60 and 80
kg/Ha) with interactive effect between them on some yield
components of cumin.

Cotton is considered as one of the most important crops grown in AL-Ghab plain and which distinguish by excessive requirements from mineral elements.The importance of this study comes in trying to increase the economic proceeds of cotton crop by guidance of using of fertilizers and keeping soil fertility
A field experiment was carried out at Abi Jarash farm, Faculty of Agriculture, Damascus University, during the two agricultural seasons 2011-2012/2013-2014 in order to evaluate the performance of some oily varieties introduced from the safflower crop
(SON-4, SON5, PI133055, Local Witness, GILA) under the influence of environmental conditions. Prevalent in Damascus governorate during the spring and summer season (intensive) after harvesting the wheat crop) using two rates of nitrogen fertilizer (control - without adding fertilizer, and at a rate of 75 and 150 kg. ha - 1 pure nitrogen unit)
Two separate pot experiments were conducted during the agricultural season (2012-2013) and a complete randomization system was used, studying the response of four certified Syrian soft wheat cultivars (Triticum aestivum L), namely (Sham 4, Sham 6, Bo
houth 4, Bohuth 6) towards nitrogenous additives and the dates of addition different types and evaluate the efficiency of these varieties in benefiting from the added nitrogen fertilizer.
