Westerman celebrated for 40 years worth of accomplishment

Robert Westerman

By Sean Hubbard, Communications Specialist,
STILLWATER, Okla. – With a career spanning over 40 years in teaching, research and Extension for Oklahoma State University’s Division of Agricultural Sciences and Natural Resources, Robert Westerman was recently recognized as a DASNR 2015 Distinguished Alumni.

Westerman of Stillwater, Oklahoma, received his bachelor’s degree in agricultural education and master’s degree in plant and soil sciences from OSU in 1961 and 1963, respectively. He joined the United States Army, where he was a helicopter pilot, before attending and graduating from the University of Illinois in 1969 with a Ph.D. in soil fertility.

After seven years on the faculty at the University of Arizona, Westerman joined OSU as an associate professor of soil fertility and plant nutrition. He quickly climbed the ranks in the department of agronomy, now known as plant and soil sciences, teaching graduate and undergraduate courses related to soil-plant relationships He was named a Regents professor and served as head of the department during his tenure.

“He's the perfect combination of a scientist and people person,” said Tom Coon, vice president, dean and director of DASNR. “His dedication to students and faculty is clear. I see him at the scholarship banquets in the spring, and he just thrives on that atmosphere of seeing support for students and support for the faculty who are teaching them.”

Westerman’s career then took him into service as the assistant director and interim associate director of the Oklahoma Agricultural Experiment Station before serving as assistant vice president for agricultural programs within DASNR administration. He retired in 2013.

“There probably aren't a lot who can make the jump from scientist to administrator,” said Gordon Johnson, retired Regents professor in soil science. “But I think he was probably driven to do this because he saw how it could help the department and then later on how it could help the division, and ultimately help OSU and the people in Oklahoma.”

Westerman has a lengthy list of research accomplishments, many connected to his efforts on the development of practices to improve nitrogen-use efficiency in crop production. He was a major adviser to more than 40 graduate students, has written over 50 peer-reviewed journal articles, nine book chapters and a book of his own.

He is a Fellow in the American Society of Agronomy and a Fellow and recipient of the Agronomic Achievement Award in the Soil Science Society of America.

“I think it all comes back to this sense of dedication and commitment he has to serving the mission of the university, but really serving the students and the faculty,” Coon said.

Also recognized at DASNR Honors night as 2015 Distinguished Alumni were Minnie Lou Bradley and James Kennamer.


2015 DASNR Distinguished Alumni, Dr. Bob Westerman

Join us for a reception honoring 2015 DASNR Distinguished Alumni, Dr. Bob Westerman. The reception will be at 10:00 AM, October 16th in room 374 Ag Hall. There will be time to share your favorite stories about Dr. Westerman and his time at OSU.

Oklahoma State Unveils New HRW Wheat Variety for 2016 Season- Bentley

In advance of the upcoming fall planting season, Oklahoma State University has announced the release of Bentley, its newest wheat variety.

“OSU has a strong history of producing high performing wheat varieties and Bentley only adds to this proud tradition,” said Jeff Edwards, head of the OSU Department of Plant and Soil Sciences. “The OSU Wheat Improvement Team is dedicated to meeting the needs of Oklahoma wheat producers and we’re excited about the ways Bentley will help them continue to thrive and succeed.”

“Bentley’s drought resistance is equal to or slightly better than Iba, which is currently our best adapted variety for drought, but it has much better leaf hygiene in the presence of leaf spotting diseases, particularly tan spot and physiological leaf spot,” said Dr. Carver, lead researcher for the OSU WIT, an interdisciplinary team of nine OSU researchers responsible for developing the variety.

Along with another OSU experimental line, Bentley earned the 2015 Millers Award presented by the Wheat Quality Council. It also has placed in the highest yielding group of varieties at every location for which three-year data (2013-15) is available for the OSU Wheat Variety Trials.

Canopeo App

New Crop Analysis App Released

Oklahoma State University is making available a new app that allows users to quantify green vegetation in a plant’s canopy in the field through photos taken using a smartphone.

Canopeo, developed jointly by the OSU App Center and students and faculty in the department of plant and soil sciences, is the first mobile application developed from concept to release through the center. It is available for download for both Apple and Android smartphones.

The free mobile app analyzes the images and provides an accurate measure of percent canopy cover for row crops, grassland, turfgrass or other green vegetation. The information can be used to monitor a crop’s growth or evaluate damage and allows the user to adjust management decisions.

“Green canopy cover is an excellent indication of crop progress, especially early in the growing season,” said Tyson Ochsner, Sarkeys Distinguished Professor in Applied Soil Physics with OSU’s Division of Agricultural Sciences and Natural Resources.

For complete story select this link: Oklahoma Farm Report Ron Hays. For information about the OSU App Center visit or talk to App Center student interns in the lobby of the Henry Bellmon Research Center on OSU’s Stillwater campus. Learn more about Canopeo at
