Farmers across the state have access to many of the most cutting-edge wheat varieties ever bred. These varieties are all created with performance in mind, so how can producers gain that coveted yield bump when the dozens of varieties at their fingertips are all, by-and-large, on a fairly level playing field? According to Dr. Romulo Lollato, Wheat and Forage Extension Specialist at Kansas State University, the genetics of all the newest varieties have improved to the point where agronomic practices now have an even greater influence on yield than variety selection does.
“I think we are at the point where we have so many excellent varieties that we don’t have to be quite as picky. There are a lot of really good options, so we have to look at management, as well,” said Lollato. “That’s what the last 19 years of data that we have collected is telling us – that management practices are very, very important.”
According to this data, management accounts for 44-77% of yield variation. Because of this large yield gap, Lollato says, “It is time to manage wheat.”
To no one’s surprise, region and irrigation make the top of the list for yield producing management practices, but application of foliar fungicide and sowing date are also incredibly important for both irrigated and dryland farmers. The largest yield drag was dual-purpose wheat used for grazing.

Sowing dates can have a huge impact on final yields, but the optimal sowing date varies by region. Western Kansas farmers have an optimal date of October 1, north central’s optimal date is October 10 and south central’s is October 12. Planting after these optimal dates can mean substantial yield penalties. The South Central region loses about 1.1 bushels per day for around 20 days following October 12, but that loss increases to around 2.7 bushels per day after those initial 20. North Central Kansas consistently loses about 2.1 bushels per day, while the western region loses a whopping 3.5 bushels.

Lollato and his team have also found that seed treatments (like insecticides and fungicides) have a higher yield bump in good seasons, while foliar fungicides are beneficial in all seasons, but have more yield gain in those higher yielding seasons. Micronutrient applications have had a negligible bump during high performing years, while they have a monster gain of 9.7 bushels per acre during low performance years.

Lollato’s research has also focused on sulfur. Kansas has seen the removal of sulfur from the soil during wheat production exceeding the amount of atmospheric deposition since 2000, which he attributes as an effect of the Clean Air Act. This legislation has meant lower levels of air pollution, but less pollution means less sulfur coming in during rainfall. Sulfur application has a slight yield drag of -.6 bushels per acre during high performing years (like 2016 and 2017) but had a net gain of around 4.9 bushels per acre during drier years like 2018. He also advised that while sulfur and nitrogen deficiencies tend to have a similar yellowed appearance in plants, sulfur tends to express a brighter yellow discoloration in the upper plant canopy while nitrogen discolors the lower canopy.L
Although management practices are the most reliable source of yield gain, variety traits can have an effect. Stripe rust resistance was the trait with the highest yield gain, but there are others to keep an eye on depending on region and management practices. In the western region’s irrigated wheat, stripe rust, coleoptile length, straw strength and winterhardiness are the highest yielding traits. For dryland wheat, those traits are drought tolerance, coleoptile length, first hollow stem date and stripe rust.
In the central region, if you’re planning on applying fungicide, look for medium to late heading, drought tolerance, acid soil tolerance and medium to short height. With no fungicide application, those high yielding traits are stripe rust tolerance, leaf rust tolerance, fall grazing potential, early heading date and drought tolerance.

MANHATTAN, Kan. — Three Kansas State University faculty members in the Department of Animal Sciences and Industry were presented awards by the American Society of Animal Science at its annual meeting in Austin, Texas.

Bob Goodband received the 2019 American Feed Industry Association Award in Nonruminant Nutrition Research, which recognizes an individual who has contributed to and published outstanding work in the last 10 years.

Originally from Walpole, Massachusetts, Goodband graduated from The Pennsylvania State University in 1984. He obtained his master’s and doctorate in swine nutrition at K-State, and joined the faculty in 1989.

Goodband and his co-workers have played an important role in developing an intensive on-farm research program that has conducted numerous on-farm trials across the U.S. His work has resulted in 310 refereed journal papers, six book chapters, more than 1,000 research reports and extension publications, eight patents, and $13.9 million in grants and gifts to K-State.

Goodband also teaches Swine Science and Swine Nutrition courses and serves as academic advisor to more than 35 undergraduate students each year. He has served as the major professor for 22 master’s and doctorate students and on committees of an additional 113 students.

Cassie Jones received the 2019 ASAS Early Career Achievement Award, which recognizes an individual who has shown outstanding achievement as a young scholar and is working toward the professional organization’s mission.

An associate professor, Jones earned her bachelor’s and master’s from K-State and her doctorate in swine nutrition from Iowa State University in 2012. As the department’s undergraduate research coordinator, Jones oversees more than 100 undergraduates conducting research annually.

She teaches more than 250 students in seven different classes and advises approximately 60 students. Outside of teaching, Jones is an accomplished researcher in the area of animal feed safety, with more than 40 peer-reviewed publications, 100 abstracts, and $6.5 million in awarded grants, gifts and contracts during her seven-year career.

Jones and her husband, Spencer, raise Angus cattle near Wamego, and have three young children — Ty, Hayden and Hadley.

KC Olson received the 2019 ASAS Animal Management Award, which recognizes an individual who has contributed to excellent research in the biological or production management of livestock.

Olson’s graduate training at North Dakota State and K-State preceded his eight-year appointment in extension and research at the University of Missouri. In 2006, he joined the K-State faculty and is now a professor of animal science in a research and teaching role.

In 2011, he was awarded the W.M. and F.A. Lewis Distinguished Chair in Animal Sciences and Industry. His research has included more than 40 K-State scientists and 25 scientists from other universities.These projects supported degree requirements for 17 master’s, eight doctorate and seven undergraduate students under his mentorship.

Over the last decade, Olson has published 62 peer-reviewed journal articles, five book chapters, 48 proceedings papers and more than 100 abstracts. He has delivered numerous presentations around the globe. Olson’s previous honors include K-State Advisor of the Year, Excellence in Graduate Teaching and Excellence in Extension.
