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.
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 plan ts class Dita (dry weight, density rooty, content of soil and plant from nitrogen) under condition of soil and climate in Deir Ezoor.
