Abstract :

In order to investigate the effect of different amounts of potassium and manganese on qualitative and quantitative yield and other traits of sugar beet in the northern of Khuzestan, a split block experiment was conducted based on complete randomly block with 12 treatments in three replication in fall cropping season October 2013-2014 in farmland of Haft Tapeh area of Susa city. A resistant mono germ genotype with high yielding named Spartak was used in this study. Examined factors included employing potassium fertilizer treatment in four levels of 0, 1, 2 and 3 kg/ha and manganese fertilizer in 0, 1, 2 kg/ha rates. Spraying with potassium fertilizer had a significant effect on root and white sugar yield. The highest root and sugar yield in treatment were achieved with 3 kg/ha of potassium fertilizer with 80.6 ton/ha root yield and 13.63 ton/ha white sugar yield. Using manganese fertilizer hadn’t significant effect on root yield and other studied traits. Also, using different rates of potassium and manganese fertilizers did not have much influence on qualitative characteristics of sugar beet such as nitrogen, sodium and potassium amounts in root, sugar extraction coefficient, molasses percentage, raw sugar and white sugar percentage. On the whole, using potassium and manganese during the vegetative growth stage of sugar beet is recommendable.
