A field experiment was conducted at Taizin Research Station for irrigation, Hama Agricultural Research Center, General Commission for Scientific Agricultural Research (GCSAR), during summer time, the growing season of 2020/2021, to study the effect of four irrigation methods (sprinkle, foggy, drip and furrow) and four levels of nitrogen fertilizer (0, 200, (+25%) 250 and (-25%) 150 kg N/hectare) on some morphological traits of sugar beet monogerm variety (Dita). The experiment was laid according to the randomized complete block design (RCBD) arranged in split plot, where the main plots occupied by irrigation methods, while the sub plots allocated with fertilization levels, with three replications. The results showed that the use of drip irrigation saves water consumed by 34.4% didn’t differ significantly in its effect on root length and diameter compared to furrow irrigation, but furrow irrigation gave significantly higher values of root and shoot and plant weight, where the percentages of increase attained to values of 22, 14 and 20% respectively. Also, the nitrogen fertilization level of 250 kg N/ha significantly increased the morphological traits, which indicated the importance of nitrogen fertilization in increasing the efficiency of plant in the photosynthesis process and increasing the percentage of dry matter accumulation, and this reflected positively on the morphological characteristics of the plant.
