Foliar application is a succesful way for a plant microelement nutriton under calcareous conditions. Study was aimed to evaluate the effects of foliar micronutrient applications on yield, mineral nutrition and some quality parameters of sugar beet. For this, solutions containing 500, 500 and 250 ppm of Fe, Zn and B and their combinations (Fe+Zn, Zn+B, Fe+B, Fe+Zn+B) were foliar applied. Compared to control, Fe+B combinations increased the root and root+leaf yield by 54% and 68%. The highest leaf Fe was obtained with Fe application, and the highest Zn and B were obtained from the Zn+B. The highest root Fe, Zn and B were obtained from Fe+Zn, Zn and B applications, respectively. Positive effects of the applications on other nutrients were determined. The highest polar sugar and total soluble solids were obtained from the Fe+B and the highest reducing sugar was recorded from Zn and B applications. Zn, B, and all combinations containing B significantly increased the α-amino N content. As conlusion, foliar application of Fe, Zn and B positively affected sugar beet nutrition and thus increased yield and quality.
