Evaluation of effects of climate condition on the quality of sugar beet production in Iran

This research has been carried out during the 9 years (1998–2008) and in some provinces (Chehar Mahal Bakhtiari, Isfehan, Qazvin, Zanjan, Azarbayejan Gharbi) in 5 sugar factories. Our aim was the evaluation of qualitative specifications of sugar beet produced in different climates and their effects on the amounts of sugar produced. Conclusions of this research were based on the analysis of 13811 samples of sugar beet consignments received during 9 years. The results have shown that amounts of sugar changed from min. 15.38% to max. 62%. K⁺ contents varied between min. 5.06 and max. 8.1; while Na⁺ varied from min. 1.8 meq to max 5.49 meq., and harmful nitrogen ranged between 1.96 to 4.37. These results showed the annual variations in the quality of sugar produced in Iran with respect to geographical variations.
