A field experiment was conducted at Hama Research Station, General Commission for Scientific Agriculture Research (GCSAR), during 2016/2017 and 2017/2018 seasons, to compare production, quality and morphological characteristics of monogerm fodder beet variety, i.e. Jamon under four levels of nitrogen fertilizer (20, 80, 120 and 180 pure units of N, urea 46%/ha). The experiment was sown in summer during September. A randomized complete block design (RCBD) was used with three replications. The statistical analysis of both seasons exhibited a significant effect of the nitrogen fertilizer (N) on all of the production traits (shoot yield (ton/ha)) and morphological traits (shoot weight per plant (g), and root length and diameter (cm)). Also, there were no significant differences in quality traits (dry matter in root and shoot (%) and sucrose (%)). The least significant difference test (LDS0.05) showed the possibility of adding 80 pure units of Urea/ha to get the best production, quality and morphological traits.

Key words: Fodder beet, Nitrogen fertilizer, Production traits, Quality traits, Morphological traits.
