A field experiment was conducted in Noubaria calcareous soil to investigate the response of sugar beet to 10 ton/fed of fresh or composted farmyard manure (FFYM or CFYM) in presence of 40 kg N/fed (as urea, ammonium nitrate or diluted nitric acid). Plant samples were taken after t 6 and 25 weeks of planting. Some vegetative characteristics such as plant height, leaf numbers, root length and width were recorded. Shoots and roots were chemically and biochemically analyzed. The combination of CFYM and ammo nitrate showed the best results of plant growth, yield, sugar concentration and purity. Positive correlations were found between sugar purity and potassium content in leaves of 16 and 30 week ages (r=0.297 and 0.296 respectively) as the only significant ones. Reducing sugar content was more sensitive to the studied treatments than the total soluble sugar content.
