Two field trials were carried out in Sakha Res. Station, Kafr EL-Sheikh Govemorate (31 N°,30 E° at an altitude,e/ev 6 m) in two successive seasons (201212013 and 201312014) to find out the performance of sugar beet crop under different plant population as well as nitrogen and boron fertilization levels. This work included 27 treatments representing the combinations between three hill spaces (15, 20 and 25 cm), three nitrogen levels (80, 100 and 120 kg Nlfed) and three boron concentrations (tap water "control", 105 and 21 O ppm) as a foliar spray. A split-plot design with three replicates was used, where hill spaces were a/located in the main plots,. meanwhile, the combinations between nitrogen and boron treatments were distributed in the sub-plots. The results showed that root diameter, root fresh weight, nitrogen and potassium concentrations of root and yields of root and tops were significantly increased with the increase in hill spaces from 15 to 25 cm. The highest significant values of sucrose and sugar yield were significantly obtained with 20 cm between hills, meanwhile, the purity percentage was recorded with 15 cm between hills, in both seasons. Root length, diameter and fresh weight, potassium and sodium concentrations in root a.§ well as yields of root and tops were significantly increased by increasing nitrogen levels from 80 to 120 kg Nlfed, in both seasons. The highest average of sucrose percentage was recorded with 100 kg N/fed, whereas, sugar yield was the highest with 120 kg Nlfed, in the two seasons. Increasing boron levels from up to 210 ppm significantly increased root length, diameter and fresh weight, sucrose and purity percentages, as well as yields of root, top and sugar and boron concentration in root, in both seasons .. The combination between hill space of 25 cm and 120 kg Nlfed gave the highest averages of root diameter and yields of root and top and the lowest purity percentage. Sugar yield recorded the greatest value with the combination between hill space of 20 cm and 120 kg Nlfed, in the two seasons. The highest average of sucrose percentage was recorded with the combination between 100 kg N/fed and 210 ppm boron in both seasons. The second order interaction of 25 cm hill space, 120 kg Nlfed and 210 ppm boron gave the highest significant top yield in the 1st season as well as root yield in the Z' season. Sugar yield recorded the highest value with the interaction between hill space of 20 cm, 120 kg Nlfed and 210 ppm boron.
