      abstract = {The paper presents an analysis of the wheat yields  variability in voivodeships of Poland. The main aim of the  study is to present several possible indicators for the  crop variability in the context of production risk. It is  found that ignoring the long-term yield trends leads to a  serious overestimation of production risk.},
