Abstract:

Two field experiments were carried out at the experimental station of Sakha Agricultural Research Station, Egypt during the two growing seasons of 2013/2014 and 2014/2015 to study the effect of foliar application with humic acid, fulvic acid and potassium humate at level 0.5%, and four soil application of nitrogen fertilization rates (36, 52, 73 and 90kgN/fed.)on yield and quality of sugar beet. Results showed that foliar application statistically improved sucrose, extractable sugar, purity, sugar lost to molasses, extractability percentages and yield (tons/ fed) in both seasons. Fulvic acid surpassed the other humic substances in the content of sucrose, extractable sugar, and purity percentages; also yield, and lowest juice impurities in both seasons. Decreasing nitrogen fertilization level from 90kg N/fed to 36kg N/fed significantly decreased all traits in both seasons, except K% and Na% in 2nd season. Applied N fertilization at level 72kg N/fed significantly maximized extractable sugar%, extractability, also root and sugar yields (tons/ fed) in both seasons. Application of 72Kg N/fed with fulvic acid helpful for suggesting good use of nitrogen fertilizer along with fulvic acid to increase sugar beet crop yield and improve its quality.
