Weed suppression ability and yield impact of living mulch in cereal crops

The objectives of this study were to investigate the impact of white clover and perennial ryegrass living mulches on weed density and yield in cereal crops. The following were tested: (1) if white clover and perennial ryegrass planted as living mulches can suppress weeds; (2) if these living mulches reduce crop yield when sown simultaneously with the cereal crop; and (3) if perennial ryegrass is more competitive than white clover.
