Robert Klein is Emeritus Professor and Western Nebraska Crops Specialist at UNL. He joined UNL in 1960 and since 1983 has been located at the West Central Research and Extension Center at North Platte. His interest in soil conservation and improving dryland crop yields and reducing irrigation water use without reducing crop yields resulted in him being one of the leaders in Ecofarming and No-Till research and extension crop production methods. The success of Ecofarming and No-Till depends heavily on managing weeds which led to his involvement in pesticide application technology in the early 1970s. This included developing equipment and procedures to analyze spray patterns of ground application sprayers. His papers have included a number of presentations at the International Advancesin Pesticide Application Conferences held in Europe. His many awards include the United States Dept. of Agriculture Superior Service Award and a Fellow in the North Central Weed Science Society.
Stephen Mason is an emeritus professor with the College of Agriculture and Natural Resources with an extensive focus on crop production and management. He has practiced the production of annual dryland summer crops such as maize, sorghum, pearl millet. Mason has researched the use of pearl millet as an alternate grain crop in crop rotations for countries in Africa and Latin America.
