Abstract
Variation was determined under homogeneous, medium intensity cultivation in two consecutive year s with barley and wheat one 143 ha farm in Bavaria. The yield vaned by a factor of two within a distance of 50 m. In both years, the yield could be explained by site, land-use and weather factors. Upslope watershed area was one of the most important site properties, indicating a strong influence of lateral water flow on crop yield. Lateral influences are commonly not considered in plot experiments or in crop growth models. It is also doubtful whether the large deviation in yield resulting from small deviations in the starting conditions can be forecast by crop growth models, even though we were able to explain them retrospectively.
