In: Mansoura University Journal of Plant Production 2011.v.2(12)Summary: Two field experiments were carried out at EI - Hamoui, I<afr EI - Sheikh Govemorate in 2009 1 2010 and 2010 12011 seasons to study the effect of four. nitrogen fertilizer rates (0. 70, 90 and 110 kg N 1 fed) and five growth regulators treatments (sprayed plants with tap water (control), Mepiquate Chloride (pix) at the concentration of 1000 and 2000 ppm and Indole acetic acid (1M) at the concentration of 100 and 200 ppm on yield of sugar beet. The experiments were laid out In spilt plot design. The obtained results showed clearly that average root 1top ratio, suaose %, potassium %. sodium %, top yield 1 fed, root yield 1 fed and sugar yield 1 fed were significantly affected by nitrogen fertilizer rates In both seasons. Increasing nitrogen fertilizer from 0 to 110 kg N 1fed caused 102.14 and 103.53 %, 112.55 and 118.18 % as well as 136.70 and 142.60% increases in top yield 1fed,
