Abstract: Nowadays, Chinese sugar beet production is mainly distributed in Northeast, Northwest and North China. In order to explore the main nutrient limiting factors in sugar beet production at present, a nutrient-deficient treatment was conducted in a two years’ field plot experiment at 23 sites of Northeast, Northwest and North China, respectively. The results showed that in the Northeast, beet yield was significantly restricted by nitrogen and phosphorus (P<0.05), the restriction of boron to beet yield and potassium to sugar content appeared in all experimental sites, the limiting sequence of all experimented nutrient elements to sugar beet yield and quality was N>P>K>B>Zn. In the main sugar beet growing region of Northwest, nitrogen and boron were the main limiting factors to beet yield, and the restriction of both elements showed a significant effects (P<0.05), concerning both yield and quality, the limiting sequence of the nutrients in sugar beet production was N>B>P>K>Zn. In the third main sugar beet growing region of North China, the restricted effects of all the five nutrient elements on beet yield had reached a statistic level (P<0.05), thereinto N was the most important one, while the other four showed a similar effects, Zn had a significant effect on sugar content (P<0.05), the nutrient limiting factors demonstrated the following sequence as N>Zn>B>P>K.
