Many agronomic practices may need to be adjusted to maximize yield and quality of sugar beet. Thus, agronomic package must be always modified. The present study was conducted in split-split plot design at the Agricultural Research Center of Al Ghab, General Commission for Scientific Agricultural Research (GCSAR), Syria. The objective was to evaluate the effect of planting dates, and length of storage on the sugar losses reduction, and some quality traits in 2014/2015 season. Tow sowing dates were settled, (15th of October, and January) (factor T). The second factor (D) was the storage durations of 6 days, and tow varieties (Factor V) were arranged as split split plot design with four replications. The varieties one of them was monogerm (Vico), while the other was multigerm (Reda). Weight percent loss and quality of beet samples such as sugar content, total soluble solids (TSS%), and purity% were determined throughout storage period. Prolonging storage period of the harvested roots leads to high and gradual increment in the total soluble solids (brix %), sucrose%, and root weight loss% (23.5, 11.3, and 9.6%), respectively. Also the results clarified low juice purity % with a percent of 9.6% at the end of storage period as compared with the first day, for the all varieties and sowing dates. The variance analysis showed that the most effective factor for the all studied traits was the storage period (factor D), followed by the sowing dates (factor T), then varieties, in a very low percent (factor V), so it can be concluded that it is very urgent to send the harvested roots immediately to the factories to be processed within 24 hours, and to grow beet mainly in autumn (15th of November).
