| Abstract: | This paper discusses the relations of sugarbeet dry matter accumulation and distribution, as well yield formation under different nitrogen levels. It indicates there is a significantly negtiwve coreection between nitrogen applycation amounts and beet root sugar content, r = - 0.973, but there are non linear corrections among nitrogen application amounts, root yield and unitarea sugar yield. The optimum nitrogen amount that can get maximum sugar yield is N120 in this study. |
