Abstract
Previous studies have shown that weight and sugar content decrease during sugar beets storage in silos. Different parameter such as size of sugar beets and height of storage, can affect on changes of weight and sugar. These parameters arewere considered in this study. Therefore, random sampling was done from sugar beets that had been carried to Shirvan sugar beet factory silos. Samples were divided in 4 groups of size (large, medium, small and mixed). These groups were stored in 4 different heights in industrial Shirvan sugar beet factory silos and after 18 days, pol and weight of beets were measured and were compared with data obtained on first day (before storing). The results showed that during storage of sugar beets in silos, maximum weight and sugar loses belonged to small sugar beets with 5.54 to 6.97 and 3.86 to 4.13 percent decrease, respectively. Also minimum weight and sugar loses belonged to samples that were stored in floor of silos with 1.69 to 1.91percent decrease. Increasing of height of storage resulted to increase of weight lose, so maximum of weight lose belonged to sugar beets that were stored in 5 meter height (silos level) and amount of it was 6.37 to 9.84 percent. Furthermore, results showed that maximum of sugar lose belonged to sugar beets that were stored in the lowest height in this study and amount of it was between 4.80 to 5.20 percent. Increasing the height of storage caused to decreasing of sugar loses, as sugar loses of sugar beets that was stored on the uppermost level were obtained between 1.77 to 2.20 percent.
