Abstract

The current examination was done at North- Eltahrer, Alnubaria Albuhaira Governorate, during 2018/19 and 2019/20 seasons. The field analyze was led to consider the impact of foliar application with alga extricate (Spirulina platensis) and Nitrogen fertilization on creation and nature of sugar beet (Beta vulgaris var. MK4200) was planted in a sandy soil under sprinkler water system framework. A split – split plot design with three replicates was utilized in the two seasons. Nitrogen focus was masterminded in the primary plots, while Algae were allotted in the sub plot. the Results demonstrated that foliar utilization of alga extract using1.0 g/l or 2.0 g/l produced significantly higher values of photosynthetic pigments), vegetative growth traits of sugar beet plants (root diameter, root and foliage fresh weight), (root and top dry weight/plant) and yield and yield components (root and top weight (g/plant and kg/fed), Sugar yield and quality traits. Higher estimations of development ascribe, and yield and its segments were gotten with adding 120 N kg/fed. The interaction between alga concentrates and Nitrogen fertilization altogether influenced complete photosynthetic pigments, all development characters, yield and yield components. The blend of 2.0 g/L alga extracts alongside 120 N kg/fed. can be prescribed to get the most extreme root yield/fed. Sugar yield was essentially and emphatically corresponded with Sucrose% followed by juice purity% and Brix% as well. Negative relationship was identified between juice purity%, and brix%.
