Abstract: Two field experiments were conducted during 2009/2010 and2010/2011 seasons in Koum Ousheem district, El-Fayoum Governorate.The major goal was to study the response of five multigerm sugar beetvarieties namely; Oscar poly, Desprez poly N, Pleno, Nejma and H polyto three nitrogen fertilizer levels, i.e., 100, 120 and 140 kg N/fed.The obtained results revealed that Desprez poly N varietysignificantly increased in growth traits, i.e., root diameter, root freshweight and sugar yield/fed, while Nejma variety significantly surpassedin sucrose% and root yield/fed, and reduction in impurities% in bothseasons.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 wasincreased from 100 to 140 kg/fed. On the contrary, a gradual reductionin sucrose% has been detected with the increase in nitrogen level over120 kg/fed.The interaction between Desprez poly N variety and nitrogenfertilization up to 140 kg N/fed. recorded the highest values in root andsugar yields/fed. Under the conditions of this study productivity of sugarbeet varieties could be maximize by supply sufficient nitrogenfertilization levels from 120 to 140 kg N/fed.
