Abstract
The field experiment was conducted in AL Raqqa Agricultural Research Center, General Commission for Scientific Agricultural Research (GCSAR), Al Raqqa/Syria, during 2011/2012 season to investigate the response of two fodder beet varieties i.e Vermon, and Jamon, to three harvest dates (10 April, 25 April, and 10 May). Split plot design was used with three replicates. The statistical analysis exhibited no significant effect of harvesting dates (H), and varieties (V), on all the studied traits, but the difference between varieties were significant in terms of sucrose % (p≤0.05). It was notably that expanding harvest period leads to an introduction in most of studied traits. The results showed that Vermon surpassed Jamon (p≤0.05), in terms of sucrose% (27.3%). The percentage of variance confirmed that the most effective factor for the all studied traits was the harvest date, followed by the varieties, except for sucrose %, which varieties had the main and significant effect. It could be concluded that harvest date could be prolonged one month after it sown on 10th September, and used Vermon variety to get more sugar content in roots.
