أجريت تجارب حقلية ( 2014 ) لمعرفة تأثير الاسمدة النتروجينية ( نترات الأمونيوم، يوريا، سلفات الأمونيوم ) بتراكيز متزايدة و بطريقتي تسميد ( نثر و موضعي ) في نمو نباتات الشوندر السكري الفتية صنف ديتا ( وزن جاف، كثافة جذرية، محتوى التربة و النبات من النتروجين ) تحت الظروف الطبيعية للتربة و المناخ في محافظة دير الزور.
Experiments were conducted on field (2014) for knowing the effect of nitrogenous fertilizers (Ammonium Nitrate, Urea, Ammonium Sulfate) in increased concentrations with two ways of fertilization (Scattered, local) in growth of the young Beet plants class Dita (dry weight, density rooty, content of soil and plant from nitrogen) under condition of soil and climate in Deir Ezoor.

The research work based on an economical study on sugarbeet crop in Deir
Ezzor during the period (١٩٨٠–١٩٩٦) and the prospective horizons of it
through the cultivated area, yield and total production in order to know the
extent of cultivation deve
lopment and the factors influencing this crop.
Results showed that the area under sugarbeet was unstable which negatively
reflected on the yield and production during the studied period.
However, these changes were not important statistically for the cultivated
area (non-significant regression), while the regression was significant for the
yield and production. The results also showed the presence of negative relation
between the area and productivity of this crop.
A field experiment was conducted in Agriculture collage –Tishreen University for two years 2011&2012 to evaluate the effect of tillage depths and nitrogen fertilizer timing application on growth productivity indicators and seeds' chemical compositi
on of peanut plant. The experiment was designed in split plots with three replicates. The main plots included shallow tillage (8-10) cm, medium tillage (18- 20) cm and deep tillage (28- 30) cm tillage depths D1, D2, D3 respectively. Timing application (split- plots) were: T1 all nitrogen fertilizer applied at planting ,T2 half nitrogen applied at planting and half at flowering ,T3 all nitrogen fertilizer applied at flowering .Deep tillage caused significant differences and increased leaf area index to (11.93,11.80) for the two seasons respectively . For dry weight/plant were (285.9, 266.6) g for two seasons respectively and seeds index arrived highest values (74.32, 74.53) g for two seasons respectively. Tillage depth increased protein and oil percentage in seeds, but the effect was insignificant. Timing of nitrogen fertilizer had significant effect on leaf area index. The best values were (11.80, 11.60) for two seasons respectively in the treatment T2, and dry weight/plant (283.0, 263.4) g/plant respectively. Significant effect was observed for seeds index. The highest values were (74.41, 74.21) g for two seasons respectively in the treatment T2, so that for protein percentage in seeds arrived highest values (24.35, 25.24) % respectively in the treatment T2. But the highest values of oil percentage were (47.10, 47.21) % for two seasons respectively in the treatmentT3. Interaction (D x T) had significant effect on leaf area index. The best values were (12.53, 12.07) for two season respectively at (D3 x T2) interaction treatments. This interaction had no significant effects on the rest of the indicators
This research was carried out during both growing seasons 2009/10 -
2010/11 at the National Center for Agricultural Research and Extension
(NCARE) / Karak Governorate / Jordan, to study the response of five barley
varieties namely Mu'tah, Yarmok,
Athroh, Rum and Acsad-176 to the effect of
four seeding rates (50, 100, 150 and 200kg/ha) and five nitrogen fertilizer levels
(0, 15, 30, 45 and 60kg/ha) on the productivity of grain and straw, the harvest
index and some phenological indicators.
It is well established that sugar content of sugar beet increases as the plant
reaches the biological maturity stage. This means that the sugar beet plant
must be left in the field to complete its growth. Farmers are usually concerned
with the hig
hest yield of sugar beet roots regardless of their content of sugar,
but sugar-processing companies are concerned mainly with the amount of
sugar extracted from a certain weight of roots, in addition to the purity of the
sugary juice.
Farmers normally receives the price of their sugar beat crop based on the
sugar content of the crop. Thus, in this type of farming, biological control is a
worldwide-procedure.
Biological maturity depends on ways of yield formation and a close control
of the mechanisms of forming yield components (no. of roots / unit area;
average root weigh; average sugar content) which require a detailed study of
the characters of the grown cultivar and the overall conditions of the growing
area.
Results showed that harvesting of sugar beet sown in fall season befor the
plant completes it’s growing cycle (in June) results in a big yield in addition to a
reduction in sugar content in the roots which inturn results in a big loss in the
national economy.
Results indicated that delaying date of harvest up to ١٨th of July markedly
increased root and sugar yield as well as sugar content in the beet roots.
Increasing nitrogen rate up to ٤٠٠ kg / ha resulted in a marked increase in root
and sugar yield / ha . On the other hand, sucrose content gradually decreased
with excess nitrogen. Higher plant density (more than ١٠٠,٠٠٠ plants /ha)
enforce for late harvesting in comparison with other densities for at least ١٠
days to obtain high yield of roots and sugar.
The research experiment was carried out during the 2007, 2008 and 2009,
seasons on grape variety Al- Helawani (10 years old) to study the effect of
N.P.K. fertilization rates and the triple superphosphate (T.S.P) application
method on some fruits
characters and growth indicators. Three fertilization
N.P.K rates were used, rate 1 (75:25:50) kg/ ha, twofold and fourfold of rate 1,
in three replicates in addition to control. The application of (T.S.P) was on soil
surface and at 30 cm depth, the percent of leaf area, shoot length, the degree of
berry colour, berry firmness were calculated. The results showed a significant
increase of leaf area, shoot length and the Berry colour compared to control.
The third rate was the best for increasing the leaf area and shoot length, while
the first and second rates were increased the colour of Berry. At the same time,
there was a gradual significant decrease in Berry firmness compared to control
when the rate of fertilizer was increased. It was also noted a significant increase
in leaf area (11%) and shoot length (4.5%) in deep T.S.P application compared
to the surface application.
