The Effect of Storage Duration on The Yield and Quality of Sugar Beet, Harvested and Storaged in Field Different Times

This research was carried out to determine the weight and quality losses in the roots of sugar beet harvested. Trials were conducted at the field of Sugar Insti-tute, Etimesgut Experimental Station, Ankara in 2013. Experiments were de-signed according to split plot in a randomized complete block with four replica-tions. Experiments were planned in the roots of sugar beet harvested at different times and stored in silos. It is used two sugar beet cultivars (Pauletta and Bison). In this research; root yield (t ha-1), sugar yield (t ha-1), sugar content (%), weight loses (%), sodium, potassium and alpha-amino nitrogen (meq/100g) content, raf-ined sugar rate (%), dry matter percentage (%) were investigated. The highest root yield was obtained when the beets harvested for Pauletta on October 5 and for Bison on October 8. The lowest yield was obtained when the beets harvested on September 28 in both varieties. The weight-loss has been detected at a rate of 29,91 % in beets stored in field silos.
