Sugar beet seedlings were field transplanted to determine sugar beet yield and quality as affected by levels and time of N application. Paper pots were used to produce sugar beet seedlings to avoided the losses in seedling through germination stage and to razing the density of plants as well. Two field experiments were carried out at Sakha Agric. Res. Station , Kafr ElSheikh Governorate during 1999/2000 and 2000/2001 seasons, to study the effect of levels and time of nitrogen fertilizer application on yield and quality d transplanted sugar beet. A split-plot design with three replications was used. The levels of N were applied in the main plots, meanwhile, the times of nitrogen application were allocated in sub plots. Tuning of plants was at four true leaves stage for C.V. Rasploy in both seasons. The obtained results showed that, the highest dose of nitrogen (120 Kg/fed) gave the highest root yield and however, with lowest sucrose %, total soluble solids in term (T.S.S.) and purity percentage. it was also noticed that there was no significant effect for levels N fertilization on top, sugar yield and Top/root ratio in booths seasons where as, time of nitrogen application significantly affected root yield, sucrose %, T.S.S. and purity percentage in both seasons while, top yield and sugar yield significantly affected in the first and second season respectively. Top/root ratio was not affected in both seasons.
