Abstract
Experiment was conducted for two seasons : 2001-2002 and 2002-2003 at Al-Kuba region , Nineva , with clay loam soil , to study the effect of three plant densities : 74100 , 88900 and 111100 plant ha-1with three varieties : Vero-monogerm ,Oscar Poly and Desprez- multigerm , on yield and some qualities of sugar beet characters . the results showed that the density 88900 plant ha-1× Vero ×growing season 2002-2003 had high significant on root yield, total sugar yield and extractable sugar yield which gave 55.2, 7.48 and 3.34 t ha-1respectively . On other hand, the second season 2002-2003 was more significantly than the first season in the above characteristic. No significant difference in sugar percentage was observed for plant density in both seasons, but Desprez variety had high significant. juice purity percentage had reached maximum (84%) with plant density 74100 plant ha-1× Vero variety at first season.
