R. Dewey Lee


I conduct statewide educational and research programs in winter and summer grain production for food, feed and bio-fuels. I work specifically on corn, wheat, grain sorghum, millet, oats, barley, rye and triticale. Most recently my extension outreach and research work has been focused on reducing crop stress in production systems and mycotoxin contamination in grain crops through conservation tillage, irrigation technologies and cover crops. In addition to grain crops, I am currently studying the production potential and adaptability of bio-fuel crops such as Camelina sativa, Jatropha curcas and Pongamia pinnata. My commodity web site is www.caes.uga.edu/commodities/fieldcrops/gagrains/index.html.
