Synopsis Reduction of wheat populations below 20 plants per square foot through systematic spacing of the individual plants produced progressively lower yields at each level. The adverse effects of reduced stand were reflected primarily in decreased head number per unit area and test weight. Head number per square foot was lowered by thinning to any level, but test weight did not decrease until the population was reduced below 10 plants per square foot.
