From the Dean

Jay AkridgeFor many of you, the message this month is ‘Welcome Back’. Whether they have been away from campus for the summer or not, when I ask people how their summer was, the most common response I get is ‘short’. I hope your summer was productive and that you also found some downtime before we launch the fall semester and many other fall activities.

Speaking of the fall semester, very soon more than 3,400 undergraduate and graduate students will begin or continue their studies in the College. Traffic and parking issues aside, I have always loved this time of year when the energy and activity on campus shifts into the highest gear in a matter of days. It is a time of promise and potential as we begin our work with new students or with returning students in new classes/new ways.

I spent a lot of time this summer around the state and the country connecting with alumni, and I regularly heard stories of faculty and staff who made a difference in their lives, pointed out a path they had not seen, pulled them through a tough time, inspired them to expand their dreams – I could go on. As we start a new academic year, I wonder how many of those moments will happen this fall – moments when our faculty and staff literally open up a new world to an undergraduate or graduate student. I am proud of the fact that the first land-grant mission – teaching – remains front and center for our College.

Dr. Marcos Fernandez and our Office of Academic Programs (OAP) team and Assistant Dean for Graduate Programs Dr. Shawn Donkin have a busy semester in store. OAP will be leading a number of teaching workshops as a complement to the work of Purdue’s Center for Instructional Excellence. These workshops are designed to help faculty and staff continue to improve what happens in the classroom as our students and the technology and approaches we have available in the classroom continue to evolve. 

While Purdue gathers student evaluations of courses and instructors, there are some aspects of teaching that are more appropriately assessed by peers, so OAP will be piloting some peer evaluation of teaching this year with the goal of attaining and maintaining excellence in the classroom. At the graduate level, Shawn is working on a new professional development series for our graduate students to aid in preparation for their preferred career path.

We will put a big spotlight on our teaching mission with the Celebration of Teaching Excellence day on September 17. Murphy Award winner Dr. Larry DeBoer and Graduate Teaching Award winner Dr. Linda Lee will give talks, and Dr. Kirby Barrick of the University of Florida will conduct a teaching workshop. Faculty and staff are also invited to participate in the Showcase of Purdue Agriculture Teaching – Innovation and Excellence in the afternoon. (Read more in this issue of InFocus.)

I am really looking forward to this academic year. We have a lot going on as a College, including rolling out our 2015-2020 strategic plan. I wish each of you a terrific fall—and thanks for all you do in support of our students.

All the best,

Jay

PS:  The Indiana State Fair is in full swing, and our College has a great new home in the Purdue Extension Ag & Hort Building.  My thanks to Danica Kirkpatrick, Dr. Renee McKee, and the army of Purdue Extension specialists and Educators, as well as all the faculty and staff who make our presence at the fair happen.  If you have any free time over the weekend, consider a trip to Indianapolis and check out the Indiana State Fair!

Traffic safety, preparation encouraged as fall semester nears

trafficAs Boiler Gold Rush and the start of the semester draw closer, Purdue is reaching out to students, faculty and staff to encourage increased diligence, attention to traffic and preparation, particularly related to the closure of northbound Interstate 65. Students attending Boiler Gold Rush will move into their on-campus housing on Aug. 17-18, accommodating a shifted Boiler Gold Rush schedule. Boiler Gold Rush will take place Aug. 19-22. Residence hall contracts for returning students begin Friday, Aug. 21. The first day of classes is Aug. 24. Purdue is alerting all students to the closure of northbound Interstate 65 and advising them to seek alternate routes to campus, to expect delays, and to watch for help and guidance from state, area, local and Purdue law enforcement agencies. Purdue faculty and staff are being reminded about possible disruptions to traffic, parking and other activities in the central campus area during the move-in days. Employees should anticipate delays and give themselves additional time for their morning commutes and/or to travel around campus for meetings during this period. Departments and supervisors are asked to exercise discretion and an extra degree of understanding if the additional activity during the workday causes unavoidable delays for workers.

Program teaches future students what agriculture has to offer

PASA studentsSebastian Macias wants to be a software engineer. Thanks to his participation in the Purdue Agribusiness Science Academy summer program, the East Chicago, Indiana, high school student got a glimpse of his future. Macias was one of 27 high school students who participated in PASA, a two-week program that targets underrepresented minorities and first-generation college students and introduces them to professional opportunities in the agriculture industry. “I enjoy robotics, and I enjoy programming,” Macias said. “It’s something I want to do as my career. I want to become a software engineer. I believe, because of PASA and other courses, I will be able to make it happen.” The program is broken down into three tracks: sustainability, forensic science and business education. Students attended classes on Mondays, Wednesdays and Fridays over the two weeks. On the other days the students traveled the state, learning about agriculture through tours provided by businesses such as Dow AgroSciences, DuPont Pioneer and Fair Oaks Dairy. Financial support was also provided by Elanco and John Deere & Co. through partial scholarships to participants.

Indiana corn, soybean crops expected to fall well short of last year

corn fieldDamaged crops from rain-flooded fields in June and July led the USDA to project big drops in the amount of corn and soybeans Indiana farmers will harvest compared with last year's bounty. Nationally, however, the crops are expected to fare better. The U.S. Department of Agriculture is projecting that Indiana farmers this fall will harvest 867.4 million bushels of corn on an average of 158 bushels per acre, down 20 percent from last year's record 1.08 billion bushels on 188 bushels per acre. Indiana soybean farmers were projected to bring in 278.8 million bushels on 49 per acre, down 9.3 percent from last year when they produced the state's second-largest crop of 307.4 million bushels on 56 per acre. Some areas of the state were hit much harder than others, and some individual fields had both heavily damaged sections as well as areas that will produce good yields, noted Dean Jay Akridge, who moderated a panel of experts analyzing the USDA's August Crop Production Report at the Indiana State Fairgrounds on August 12.

Survey confirms expected decline in Indiana farmland values

farm landResults of a new Purdue University survey show farmland values across Indiana fell in the past year, in line with a slight pullback analysts anticipated after a decade-long rally. "The results are about what we expected," said Michael Langemeier, Purdue agricultural economist and farmland value specialist. "There were no large surprises." According to the Purdue Land Value and Cash Rent Survey, prices for the state's top-quality farmland declined by 5.1 percent, from an average of $9,765 an acre in 2014 to $9,266 this year. Farmland considered to be of average quality fell by 3.8 percent, from $7,976 to $7,672, and prices for low-quality land fell 4.8 percent, from $6,160 to $5,863. It was the first time since 2009 that all three classes of farmland declined in value in the same year. Values fell in all parts of the state except the 15 counties in southwest Indiana, where prices rose by 13 percent for the best available farmland.

Purdue Extension offers more instruction on 'rainscaping'

rainscapePurdue Extension is continuing its "rainscaping" education program by offering another workshop for people interested in learning how to create attractive home or small-scale community rain gardens while minimizing runoff of pollution. The workshop on Sept. 17-18 at the IUPUC Campus Center, 4601 Central Ave. in Columbus, will teach community leaders how to promote community awareness and provide education for rain garden planning, installation and maintenance. It is structured specifically for Purdue master gardeners, personnel in conservation agencies and organizations, storm water professionals, and landscape professionals and consultants. "Landscapes with rainscaping capture stormwater, which reduces polluted runoff from homes and communities," said Kara Salazar, sustainable communities Extension specialist. The workshop is part of a pilot project of the Purdue Rainscaping Education Program, which conducted similar workshops in the spring.

Industrial hemp production focus of Purdue field day

hemp fieldThe agronomic and economic potential of industrial hemp, as well as the legal issues surrounding its production, will be the focus of a Purdue Extension field day on August 25. Hemp, one of the world's oldest cultivated crops, was once an important source of oilseed and fiber in the United States, where the hemp industry flourished for centuries until shut down by the Marihuana Tax Act of 1937. The 2014 Farm Bill legalized the growth of industrial hemp for research purposes, but the nearly 80-year freeze in hemp production has left information gaps on how to best produce the crop. Purdue researchers have planted test plots of industrial hemp to help provide answers to basic questions of its production. "This field day will allow the public to see hemp production firsthand - in one of the worst growing seasons in Indiana history," said Janna Beckerman, professor of botany and plant pathology. "We've used our present experience growing hemp and years of additional experience with other cropping systems to inform our production practices. What we have learned sometimes conflicts with the 'conventional wisdom' found on the Internet, but we invite people to come see for themselves."

Surprise finding: Lake Michigan perch quickly changed course of ‘reverse evolution’

perchOver-fished yellow perch in Lake Michigan have recovered much quicker - by hundreds of years - in reaching reproductive maturity at a later age and larger size than scientists previously thought was possible, according to a Purdue University study. Analysis of fish assessment data going back to the early 1970s showed the species reversed a trend of reaching reproductive maturity at an earlier age and smaller size than what had been normal. The study period included a time of very high commercial fishing of yellow perch followed by a ban on commercial fishing in southern Lake Michigan. Researchers have long suspected that size-selective fishing - in this case, catching only big yellow perch - can lead to "reverse evolution," in which fish become genetically programmed to mature earlier and smaller and, consequently, produce small fish. "Every expectation was that recovery would take a super-long time," said researcher Tomas Höök, associate professor of fisheries biology in the Department of Forestry and Natural Resources and associate director of Illinois-Indiana Sea Grant. "But we saw that maturation traits of perch in Lake Michigan recovered very rapidly - in a couple of decades."

Purdue researchers report sweet corn could make animal vaccines safer

corn adjuvantAnimal vaccine manufacturers could benefit from the work of two Purdue researchers who are testing biomaterial made from sweet corn to make vaccines safer. Harm HogenEsch (right), a professor in the College of Veterinary Medicine, and Yuan Yao (left), associate professor of food science, are developing biomaterial from a non-genetically modified variety of sweet corn to use as an adjuvant in animal vaccines. Adjuvants are substances that are added to vaccines to stimulate an immune response and to improve the performance of vaccines. Commonly used adjuvants like oil emulsions and aluminum have a number of drawbacks, but the corn-derived biomaterial being developed and tested at Purdue may address these issues in a sustainable way.HogenEsch and Yao are looking to develop the corn-based adjuvant with industry partners.

June-July rainfall in Indiana not a record, but it's close

heavy rainJuly rainfall combined with June's historic rains to turn the two months into the second-wettest June and July on record in Indiana, according to the Indiana State Climate Office. Rainfall during six weeks from about June 7 to July 21 totaled 15.09 inches, said the climate office, based in Purdue's Department of Agronomy. The wettest June-July was in 1958, when 16.15 inches of rain fell in Indiana. A preliminary statewide total of 6.05 inches of rain fell in Indiana in July, ranking the month as the seventh-wettest July since records began in 1895. The wettest July was in 1992 with 8.55 inches. June set a record as the wettest June in Indiana at 9.04 inches. That exceeded the previous record of 8.13 inches in 1958.

Study: Biology, not just physics, controls release of scent compounds from plants

Dudareva teamResearch led by Natalia Dudareva, distinguished professor of biochemistry and of horticulture and landscape architecture, suggests active biological mechanisms transport scent and taste compounds known as volatiles from plant cells to the atmosphere, a finding that could overturn the textbook model of volatile emission as a process that occurs solely by diffusion. Volatiles play key roles in plant pollination, reproduction, defense and communication. Researchers thought volatiles diffused through the plant's porous outer cuticle once they built up in high concentrations inside the cell. But the research found disparities between observed volatile release rates and the mathematics of the diffusion model. The researchers showed that toxic amounts of volatiles would accumulate in plant cell membranes if diffusion were the only mechanism at work in their release. They posited that biological mechanisms must also transport volatiles. "This is a completely new way to think about this important biological process," Dudareva said.

Partnership provides farmers timely resources for managing soybean diseases

Kiersten Wise Purdue Extension has joined six other universities from the Midwest and Ontario, Canada, in a partnership with the North Central Soybean Research Program to create a series of reference materials helping producers identify and manage a variety of soybean diseases. The Soybean Disease Management series will be updated regularly with the latest available information on diseases and management options, said Kiersten Wise, Purdue Extension plant pathologist. Wise said the project began in 2013 with the outbreak of Soybean Vein Necrosis Virus. Experts from the participating institutions stay in regular contact and develop resources on different emerging diseases each year, Wise said. The group has also used recent research to update past publications on common diseases such as white mold and charcoal rot, and soybean seedling blights. All Extension plant pathologists in the North Central region review the publications prior to release.
