Statistical data from the years 1950-2002 included in (GUS) and (IERiGŻ) reports were taken as the source of data to be analyzed. Statistical characteristic of variables for basic production parameters were processed by evaluating extreme values and variation coefficients. The patterns of changes for area under crop, yields per hectar, total grain yields, wheat rye, barley, triticale, cereal mixtures, and oat yields were presented as the regression equations. The dynamics of production changes varied among different cereal species. The rate of changes over the years 1989-2002 was described for industrial processing.
