The Association of Research Directors, Inc. (ARD) is the official representative body of the agricultural research administrators of the eighteen 1890 Land Grant Universities. Through its role of supporting and enhancing 1890 research in the food and agricultural sciences, the ARD has held symposia for the sharing of knowledge since 1976. The 16th Biennial Research Symposium, with support, participation, and conscientious and excellent work of many from the 1890 universities, is an initiative that brings us much pride. We are overwhelmingly grateful for your participation in this major endeavor of the 1890 Family and also give our heartfelt thanks to the federal agencies and 1862 land-grant universities which provided both financial and programmatic support. Finally, we thank our students and colleagues who will be the symposium highlights – the providers of excellent poster and oral presentations in the food and agricultural sciences, as well as those who will speak at the general sessions and workshops. We look forward to our award ceremonies in which many will be honored for outstanding achievements, both through professional endeavors and award winning presentations. The details of putting on such a massive endeavor were handled exceptionally well by the Symposium Steering Committee and associated subcommittees, the webmaster, and the Technology Committee and all of these individuals are gratefully acknowledged in the Symposium Proceedings. Of course, Dr. Orlando McMeans is thanked with great fervor for serving as the chair of the Steering Committee. The Research Directors and the Associate Research Directors provided excellent leadership and involvement and are commended for advancing excellent research, academic and outreach programs at respective 1890 institutions. As has been said consistently by Chairs of the ARD who preceded me, on behalf of the ARD, I am proud of the excellence demonstrated consistently at the member institutions. I hope this symposium proves to be enlightening and enjoyable for all of you and that you will feel we have met our goal of ―providing a forum for interactions, knowledge sharing, building networks for expanded partnerships and showcasing the talents and achievements of the 1890 community.‖ Sincerely, Dyremple Marsh, Chair Association of 1890 Research Directors, Inc. iii 1890 Land-Grant Universities The 1890 Land-Grant Universities and Tuskegee University, commonly referred to as ―the 1890s,‖ are those institutions established under the Second Morrill Act of 1890. These Historically Black Institutions share the land-grant mission of teaching, research, and extension. The eighteen (18) 1890s are located in seventeen (17) states shown on the logo of the Association of 1890 Research Directors, Inc. (ARD). Having as its motto ―Progress through Research and Service,‖ the ARD brings together the administrators of the 1890 Research Programs at these land-grant universities to conduct regional research projects and initiatives and to collectively promote the training of young researchers as well as the research goals of their institutions in a way that benefits their states, region and the nation. ARD members serve on state, regional, national and international bodies.
