Abstract
A field Experiments in two agricultural locations were carried out to evaluate three levels of phosphorous fertilizer (60,80,120)Kg P/ha, as super phosphate and five varieties of sugar beet, Monogerm (Vero, Rosana, Rosa) and, Multigerm (Gitane, Monterosa). Results showed the yield of root (ton/ha) increased significantly as the fertilizer increased, which gives (20. 3 % ,24.6%) when compared with first level added of phosphorous fertilizer respectively , The root sugar also increased as compared to the first level (0.65%,0.89%) respectively in both locations, Monogerm (Vero, Rosana, Rosa) gave a high yield of sugar and purity when compared with the Multigerm ,Vero surmount to the others Monogerm Rosana and Rosa at the two locations .So phosphorous fertilizer and the Monogerm of the sugar beet increased the quantity and Improved quality at the two locations under Iraqi conditions
