MAJOR CONTRIBUTIONS
Summer annual grasses, such as forage sorghums and pearlmillet, are used
extensively for supplemental pastures and feed for dairy cows to maintain high levels of milk
production during the dry and hot summer months. Dr. Fribourg was one of the first
investigators to study the management required for these plants to grow back vigorously after
cutting or grazing, and to determine that high stubbles were necessary for some, but not for
all, cultivars. His research on these plants is well documented in the scientific literature and in
popular articles, and he is the author of the chapter on these plants in three editions of the
most-used textbook on forage crops.
Prior to Dr. Fribourg coming to Tennessee, bermudagrass was considered a weed. In
fact, it covers an estimated 350,000 ha (750,000 acres) or more in the state. He has
determined ways of using this warm-season plant in a useful and economical way for beef
production. His research showed how to produce up to 12 tons of hay annually per hectare
(12 ton/acre) with Midland bermudagrass when only 3 to 4 tons can be produced with
common bermudagrass. He has investigated ways to manage pastures of Midland and
common bermudagrasses to produce over 450 kg per ha (500 lb/acre) per year liveweight
beef gains, about twice what producers in the 1950s. He pioneered in finding out how to
manage bermudagrass pastures to introduce and maintain a cool-season grass, tall fescue,
in the sod, thereby increasing the normal grazing season of five months to almost ten
months. He led in the successful effort to find means to maintain legumes in bermudagrass
pastures.
Dr. Fribourg's name is now associated with the management of Midland
bermudagrass. Although most of the initial research with this crop in Tennessee was done by
him alone, much of the later research involving cattle was conducted in collaboration with
animal scientists and agricultural economists. Dr. Fribourg led such team research, where
interpersonal and interdepartmental relations are sometimes delicate and require tact and
diplomacy.
Dr. Fribourg recognized early in his career that crop plants do not live in a vacuum,
but rather that their life and performance for human use depend on many inter-relationships.
He carried out much macro- and microclimatic work, and published in this area. He was the
first to verify the validity of a precipitation model, derived in the Midwest, for both theoretical
soundness and practical use in the Southeast. His publications in probability occurrences of
climatic parameters for Tennessee are useful not only to agriculturists of all kinds, but also to
engineers, industrialists, architects and planners, and real estate and tourism industries.
Soil characteristics and properties influence greatly crop plant performance. Dr.
Fribourg is one of the few crop scientists who has worked with soil scientists to help
characterize the potential value of different soils on the landscape as these affect forage
crops. With a forester, he compared the value of forage crops and trees for use on soils
marginal for crop production.
There are over 1.6 million hectares (3.5 million acres) of tall fescue in Tennessee, a
tenth of the US area in that forage, used to graze the 2 million beef cattle in the state.
Research in improving the usefulness of this pasture species lagged for many years,
because tools were not available for repeatedly identifying negative quality factors. Dr.
Fribourg was instrumental in alerting the Tennessee Agricultural Experiment Station to the
tall fescue fungal endophyte problem as soon as reports from other states indicated that
Neotyphodium coenophialum was a probable causative agent. As a result, Tennessee was
9
Resume, Henry A. Fribourg, November 2009
able to create new research programs in this area starting in the late 1970s and is now in the
forefront of the studies on this problem and related aspects of attempts to circumvent the low
quality of infested tall fescue pastures.
Renovation with legumes is one of the best ways to improve an endophyte infested
tall fescue pasture. Dr. Fribourg pioneered in determining that insects were detrimental to
clover stands and that some chemicals could help in the establishment of clover in tall fescue
pastures. Research on tall fescue renovation initiated in Tennessee was emulated in other
states and is the basic underpinning of extensive agricultural extension programs in
Tennessee and adjoining states.
Ever since the advent of computers on the University of Tennessee campus in the late
1960s, Dr. Fribourg was a leader in their use and generously contributed his knowledge by
publishing well-documented programs for teaching and research. He pioneered in the joint
use of statistics and computers to help explain the effect of concomitant variates on crop and
livestock characteristics of value to agriculturists and scientists. He was the first to publish on
the use of factor analysis in agronomic research and to show its usefulness, in conjunction
with multiple regression techniques, for developing models describing crop plant and beef
cattle responses.
His research on the influence of stage of development of plants at harvest for silage
production is basic to the recommendations used throughout the state for both beef and dairy
cattle. His contributions in this area were recognized when he was invited to participate in an
American Society of Agronomy symposium on that subject.
During the 1990s, Dr. Fribourg continued working on the forward and exciting fringes
of agronomic research. At his retirement in 2001, this research promised to lead to 50 to 100
percent greater cattle gains from tall fescue pastures, to improved reproductive competence
in cows, and to elucidate interactions among forage and grazing systems, environment, and
beef cattle genotypes. He was leader or co-leader in research projects dealing with the
ecology of crops in forage management systems, the utilization of endophyte infested and
endophyte free tall fescue in forage systems for beef cattle and equines, the determination of
causative agents for tall fescue toxicosis, and the quantification of methane exhalations by
ruminants, in cooperation with colleagues in Animal Science, Entomology and Plant
Pathology, and Veterinary Medicine. Under these projects, seven grazing experiments and
several agronomic experiments were conducted.
After his retirement, Dr. Fribourg maintained his activities in these projects on part-time appointment,
pending the completion of several manuscripts. Topics under investigation included determination of the
effects of management and genotypes on establishment and maintenance of endophyte free tall fescue;
quantification of the effects of the presence of Neotyphodium coenophialum on pasture productivity and quality
for steers, calves and beef cows; interactions among environments, beef animal genotypes, fall & winter
calving seasons, and forage-animal management systems; development of management systems for
maintaining ecological balance of mixtures of tall fescue, bermudagrass, and legumes in pastures; refinements
in data collecting and analysis techniques for handling concomitant variables that affect forage plant
performance and utilization; and cooperation with animal scientists to measure animal responses to different
forage systems and the effect of the fungal endophyte on nutrient absorption and utilization by ruminants. With
a former student at another institution, he edited the first online monograph in agronomy, the Tall Fescue On
Line Monograph (TFOLM), gathering over fifty authors and colleagues worldwide for this 3-year effort. In 2004
through 2009, he was senior co-editor of Agronomy Monograph 53, Tall Fescue for the Twenty-first Century,
and of its online version. In 2011, he was co-editor and one of the 27 contributing authors of Country
Pasture/Forage Resources Profile for the United States of America in the online book published by the Food

and Agriculture Organization of the United Nations..
Lastly, Dr. Fribourg was not content to do research only. He willingly shared his
knowledge and experiences with students and the general public and internationally. He
supervised 12 doctoral student dissertations, 23 master s theses, and was a member of 46
other graduate student committees. He accepted and carried out successfully a number of
foreign teaching and program evaluations in southwest Asia, Latin America and Africa. In
retirement, Henry continued his avocation of family genealogist, published his
autobiographical memoir I Gave You Life Twice, sorted through his extensive stamp
collection, and continued his exploration of the world.
