Seed conditioning removes undesirable material including debris and stray seeds from selected raw harvested seed, so as to create planting seed that delivers high yielding crops. This two-volume set provides a major up-date of previously published work. It describes the essential information needed to understand this process and the machinery involved.  It describes the machines available to seed conditioners and explains how they can be installed, operated, adjusted, and maintained to give complete and precise separations for many years.

All the machines are described in sufficient detail, sometimes with the help of models to enable the conditioner to get good results. The book also details the operating sequence used to properly prepare seed before going into each machine.

Organized in a logical sequence, it catalogs all the entire field of seed conditioning, to help seed managers, specialists, and conditioning operators reduce loss of good seed while improving seed quality and honing the efficiency of their operations.
