Field experiments were carried out during the two successive growing seasons
of 1999/2000 and 2000/2001 to study the effect of varying plant sparing as well as
levels and frequency of N on the yield and yield components of sugar beet. Results showed that increasing plant spacing from 20 to 30 cn{ between hills
increased root length, diameter and weight a swell as root yield, weight of leaves per
plant sucrose percentage and juice purity. Planting kawemira sugar beet plants at hills 30 cm apart and s pplying them
with 80 kg N/fed as three equal batches before the first, second and I hird irrigation
was responsible for producing an economical yield. While, the highest sucrose
percentage was recorded when sowing it at 30 em between hills and adding 60 kg
N/fed at three equal batches at the same previous time. These results were true
under Upper Egypt conditions.
