| Abstract | ||
| Two field experiments were conducted during 2009/2010 and 2010/2011 seasons in Koum Ousheem district, El-Fayoum Governorate. The major goal was to study the response of five multigerm sugar beet varieties namely; Oscar poly, Desprez poly N, Pleno, Nejma and H poly to three nitrogen fertilizer levels, i.e., 100, 120 and 140 kg N/fed. The obtained results revealed that Desprez poly N variety significantly increased in growth traits, i.e., root diameter, root fresh weight and sugar yield/fed, while Nejma variety significantly surpassed in sucrose% and root yield/fed, and reduction in impurities% in both seasons. Application of 140 kg N/fed. maximized yield productivity, represanted by improved average root weight, root and sugar yields/fed. However, juice impurities were increased as nitrogen level was increased from 100 to 140 kg/fed. On the contrary, a gradual reduction in sucrose% has been detected with the increase in nitrogen level over 120 kg/fed. The interaction between Desprez poly N variety and nitrogen fertilization up to 140 kg N/fed. recorded the highest values in root and sugar yields/fed. Under the conditions of this study productivity of sugar beet varieties could be maximize by supply sufficient nitrogen fertilization levels from 120 to 140 kg N/fed. | ||
