Grain test weight often is used as a measure of seed quality, but test weight is a bulk density or a weight-per-volume measurement, and small seed that packs well can have a high test weight. In the seed-cleaning process, a gravity table will remove the light seed. This website uses tracking tools, including cookies. Weed competition can be reduced by using narrower row spacing. Reynolds commits to broadband funding. The optimum stand is less than hard red spring wheat (HRSW) because the crop will have more opportunity to tiller in the early spring. Plant Rate Calculator.
