ABSTRACT
Seed can seldom be planted in the condition in which it comes from a harvested field. Almost every seed lot will contain undesirable materials which lower one or more aspects of the seed’s quality. In fact, many seed lots contain weed or crop seed or inert material that make them unfit for sale without conditioning. Crop seed also frequently have stems, awns, clusters, or other structures which prevent them from being easily planted. A complex and specific sequence of operations is required in order to provide highquality seed to farmers (Figure 3.1).
