    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.

    Dr. Bill Gregg has managed seed conditioning programs, done research on development and design of machines, helped manufacturers of equipment, written operation and maintenance manuals, trained managers and operators, and helped design and install many seed plants in several countries.

    Gary Gillups is President of Crippen International which has installed seed plants in all continents except Antarctica. The level of technology provided ranges from simple portable equipment to large fully-automated conditioning plants for organizations ranging from small-to-large private companies to governments and international agencies.
