Tow field experiments were carried out at the experimental farm of Delta Sugar Company, El-Hamoul, Kafr El-Sheikh Governorate, Egypt., during 2011/12 and 2012/13 seasons. The objective of this work was aimed to study the effect of two plant density (46000 and 52000 plants/fed) , three Magnetic IronOre rates ( 0 , 150 and 300 kg/fed) and four Calcium Nitrate rates ( 0 , 1 , 2 and 3 liter/fed) on root yield and its quality of sugar beet cultivar "Toro". A split-split plot design with three replicates was used. It could be summarized finds results as follows: Application of plant density of 52000 plants/fed, Magnetic Iron Ore rates of 300 kg/fed and  Calcium Nitrate rates 3 liter/fed were recorded highest of root dimensions, plant dry matter as well as top, root yields, sugar and purity percentages in both seasons. It could be recommended that planting sugar beet plant density of 52000 plants/fed and fertilization using Magnetic Iron Ore at rates of 300 kg/fed and foliar application of  Calcium Nitrate at rates of 3 liter/fed maximized sugar beet yield per unit area under El-Hamoul, Kafr ELSheikh condition.
