In corn, protein, oil, and starch content were measured. Data were converted to a 15.5 percent moisture basis, and reported to the nearest tenth of one percent. Oil data also are reported on a dry matter basis for comparison with commonly used contract terms. The conversion to dry basis is purely mathematical in the ratio of dry matter percentages. These statistics are based on the latest calibrations from the ISU Grain Quality Laboratory.
Some users prefer large or small seeds.
In certain situations, seeds of a certain size process or handle better. In the Seed Weight Test, a mechanically counted number of seeds is weighed. Data are reported to the nearest gram. A proportionate moisture correction is applied to adjust data to 15.5 percent moisture basis. Harder seeds are generally denser.
