Improving Seed Conditioning

Bill Gregg holds a B.S., M.S. and Ph.D. in Agronomy Seed Technology. He has held positions of leadership in developing, managing and operating seed technology programs,  training personnel and guiding operations at Mississippi State University, Washington State University, and Auburn University in the U.S.A., and as a consultant and advisor in various aspects of seed improvement, seed industry development, personnel development, seed promotion to farmers, in approximately 90 countries in programs sponsored by various national government and private sector agencies, and international development programs. In Seed Conditioning, he worked with equipment manufacturers in research and development of machines, and manufacturing of machines. He worked in actual conditioning of seed of many crops. He trained operators in seed conditioning. He worked in maintenance and repair of seed conditioning machines. He designed and built/installed seed conditioning plants worldwide, probably more plants than any other person worldwide. In many countries and many plants, he examined problems in seed conditioning and developed solutions. He has a significant number of publications on various aspects of seed conditioning. He is widely known jokingly as “Mr. Seed Conditioning."  As a measure of his status, he has been included in Who’s Who in the South and Southwest of the USA, Who’s Who in America and Who’s Who in the World. In 2000 and 2001, the International Biographical Centre of Cambridge, England, selected him as International Man of the Year in Recognition of his services to the international seed industry.
