Abstract

Two field experimental were carried out at 71 Km West Nubaryia Cairo Desert Road El- Behara Gov. Egypt during two successive seasons 2014/ 15 and 2015/ 16 to study the effects of four nitrogen fertilizer rates (without, 33.5, 67 and 100.5 kg N/ fed.), four potassium fertilizer rates (without, 16, 32 and 48 kg k2o/ fed.) and their interactions on yield and quality of multigerm sugarbeet cultivar (Magribl) grown in sandy soil under drip irrigation system were investigated at West Noubaryia region condition. In this split plot design, the main plots were assigned to rates of nitrogen fertilizer and potassium rates were arranged to random as the sub- plots. The results indicated that increasing nitrogen and potassium fertilizer rates significantly increased yield characterizes, roots, top and sugar yields (tons/ fed.). Adding the highest rates of nitrogen (100.5 kg N/ fed.) and potassium (48 kg K2O/ fed.) produced the highest sugarbeet yields of roots (34.98 and 29.39 tons/ fed.), top (28.73 and 22.53 tons/ fed.) and sugar (4.76 and 3.82 tons/ fed.), respectively. Increasing nitrogen rate up to 100.5 kg N/ fed. and potassium rate up to 32 Kg K2O/ fed. significantly, increased of some juice quality, total soluble solids (T.S.S) and sucrose concentration in roots juice. While the other juice trait, purity percentage was insignificant affected by nitrogen and potassium application rates. The maximum T.S.S% (21.37 and 20.43) and sucrose% (16.90 and 16.36) was achieved by adding 100.5 Kg N and 32 Kg K2O/ fed., respectively. Also, increasing nitrogen and potassium fertilizer rates significantly increased impurity parameters, (Na, K, α- amino nitrogen percentages and loss sugar%) as well as decreased QZ%. In conclusion nitrogen fertilizer application at a rate of 100.5 kg N/ fed. accompanied with 48 kg K2O/ fed. was found to be the most favorable for improving the yield and quality of sugarbeet grown in a sandy.
