SECTIONAL ESTIMATION AND CLUSTER ANALYSIS FOR LINEAR EFFECTS OF RICE TO NITROGEN FERTILIZER

    Graphical Abstract
    • Abstract
  • The method of sectional linear regression to estimate the effects in the experiment of three factors' combinatory design was introduced. The estimated linear effects of nitrogen fertilizer in 21 rice fertilizer experiments located in different regions of Zhejiang Province were divided into 3 types by the means of systematic cluster analysis and the significant test between two nearby groups.
