Abstract
Two field experiments were conducted at Kom-Osheem Agricultural Research




Fayoum Governorate during 2003/2004 and 2004/2005 growing seasons to




the performance of four sugar beet varieties, Injermono and Helena (mono




and Sultan and Baraca (multi-germ) grown under two planting populations




and 46666 plants/fed) and three N levels (60, 80 and 100 kg N/fed). A split-




design with three replications was used. The main plots were assigned to the




planting densities while the combinations of sugar beet varieties and N




n leve’s were randomly distributed in the sub-plots.




The results showed that sowing sugar beet at 46666 plants/fed significantly




root length (in the  season) and increased both of purity % and root




(in the 2 season) and sugar yield/fed (in the i season). Root diameter,




% and top yield/fed were insignificantly affected by plant densities in both




The examined sugar beet varieties significantly differed and Sultan variety




the superiority in all studied traits in both seasons.




Increasing N doses from 60 up to 100 kg/fed increased significantly root




and diameter as well as root and top yields, while sucrose and purity




tages were significantly decreased.
