In order to investigate the effect of foliar application of boron and potash on some qualitative characteristics of sugar beet, a experiment with 3 replications was conducted in a randomized complete block design in research farm of Shahrekord University. Qualitative characteristics of sugar beet root include molasses sugar content and harmful nitrogen. Non-sugary substances, especially nitrogen, reduce the crystallization of sucrose. Fertilizer treatments include: 1-control (without fertilizer application), 2- potassium from TRUST K2O source with 2-3 liters per hectare, 3-boron from TRUST BORON source with concentration of 1 per thousand an‎d (4) boron + potassium. The results showed that the effect of foliar application of boron and potash on the amount of harmful nitrogen and molasses sugar was significant. The lowest amount of nitrogen and molasses sugar was observed in the potash foliar treatment, which was not significantly different from the boron + potassium foliar treatment. Therefore, foliar application of boron and potassium is recommended to enhance the quality of sugar beet root
