Cultivar mixture effects in winter barley as dependent on location and production intensity Grain yields of high‐yielding six‐rowed winter barley cultivar mixtures were compared with those of pure stands under different production intensities in field trials over two years and two locations. Generally, mixing effects tended to be positive with low and negative with high intensities. Significantly negative mixing effects could be observed each year at both locations with highest production intensity. Significantly positive mixing effects could be observed in one year at one location only‐ Mixing effects could not be explained by the observed levels of diseases and lodging. There were, however, relatively close correlations between mixing effects on grain yields and on grain numbers/m 2
