| 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. | ||||
