Abstract

:The growth of sugarbeet tops was significantly promoted by nitrogen fertilizer applied there are conic correlations among nitrogen application amounts root yield and sugar yield.There is a significantly negative correlation between nitrogen application amounts and sugar content in root excessive nitrogen application made against dry matter distribution in reason and reducing root and sugar yield.There is a positive correlation between nitrogen application amounts and nitrogen content in sugar beet plant with nitrogen application amounts increasing K contet of tops significantly decreased and K content of root increased the optimum nitrogen amount is 120kg/ha in this study.
