Abstract
The relations between yields (Y) or yield year-to-year variability (YV) of winter wheat and spring barley in years 1993- 2001 in districts of the Czech Republic to environmental and production indicators were studied. We found mostly significant relationships between Y and soil conditions, average precipitation and temperature, fertilizer consumption, animal production and concentration of cereals. Fertilizers explained up to 70 % of Y differences among districts, but
other factors only 50 % and less. The relations of YV and the indicators were mostly weaker than that of Y.
