Biographical NoteReturn to Top

Lyman Sessions Willardson was born in Ephraim, Utah on May 10, 1927 to Lyman Young Willardson and Alice Sessions. He attended Snow Junior College graduating in 1948 with an Associate of Science degree in engineering. On October 8, 1948 he married Vivian Berrey in Evanston Wyoming and together they had six children. Lyman obtained a Bachelor of Science degree in Civil Engineering with a speciality in irrigation from Utah State Agricultural College in 1950. After graduation, Lyman worked for the U.S. Soil Conservation Service in Logan while working towards a master's degree. In 1952 he moved with his family to the Dominican Republic to accept a position as an irrigation engineer with the United Fruit Company. He joined the Agricultural Experiment Station of the University of Puerto Rico where he conducted irrigation and drainage research from 1954 to 1957. He returned to Logan, Utah as a research irrigation engineer with Utah State University. In 1965 he attended Ohio State University completing a Ph.D. in agricultural research. He then moved to Imperial Valley in California where he continued to work in irrigation and drainage engineering research for the Agricultural Research Service in the USDA. In 1974 Willardson returned to Logan becoming a professor of Irrigation and Drainage Engineering at Utah State University. He officially retired in 1994 but continued to teach and conduct research until the spring of 2005. He passed away on October 5, 2005.

Plot 06-6A
1956 June 29
1312
13:12:21: Note border of good growth along east edge (foreground) which obscures true growth. Growth on north fairly uniform and about 1 1/2 feet tall; south half scrubby about 1 foot tall with thin stand. Fall Barley.
Plot 07-6A
1956 June 29
1312
13:12:22: Fall barley. The east (near) margin, a little less than half the plot is quite good. The west half of plot is quite uniformly short scanty growth, possibly slightly better to the north. The thin stand can be seen behind marker

Plot 01-3A & 02-3A
1956 June 30
1312
13:12:52: In general these plots have a good crop. Near the middle of each is a zone where growth is restricted so that top of crop has a wavy appearance, low in the middle, high at the common boundary and then low again. These plots had near the highest-yield.
