Lia B. Olmedo Pico Wins Nelson Yield -Limiting Factors Graduate Student Scholarship

Lia Belen Olmedo Pico, Purdue University, West Lafayette, IN – Nelson Yield-Limiting Factors Graduate Student Scholarship: Lia B. Olmedo Pico is a PhD candidate in the Department of Agronomy at Purdue University. While in Argentina, her home country, Lia received a B.S. in agricultural engineering from the University of Catamarca, earned a M.S. in crop production from the University of Mar del Plata, and worked as an assistant researcher for the National Institute of Agricultural Technology.

Lauren Schwarck wins NACTA Teaching Award

Lauren has been involved with NACTA through her undergraudate and graduate degrees as a participant and coach in their yearly judging conference. The purpose of this award is to recognize and reward NACTA graduate student members who are involved in classroom instruction who excel as teachers in the agricultural disciplines.

 

The NACTA Graduate Student Teaching Award is a criterion-based award and is reviewed by a committee of NACTA members. To qualify for the award, a graduate student must have been involved in classroom teaching for a minimum of one year. Criteria included in the evaluation are the graduate student's teaching philosophy, statement of support from supervising faculty, evaluations submitted by students and an administrative officer, a self-evaluation, involvement in teaching outside, and a description of the candidate's specific teaching involvement.

Late-season N payback depends on what's been applied

Planned, late-season nitrogen applications are more common today than they used to be. Seed company representatives and agronomists believe modern corn hybrids use a bigger percentage of nitrogen later in the season compared to top hybrids of the 1970s or 1980s.

Tony Vyn, a Purdue University Extension agronomist, says it’s true that modern hybrids use more N later. And while it’s logical to assume that means the later you apply, the better, he hasn’t proved this in his research trials.

Schwarck, Roth earn ICMC scholarship for corn-related research at Purdue

Purdue University grad student Lauren Schwarck and doctoral candidate Richard Roth earned the Indiana Corn Marketing Council’s (ICMC) Gary Lamie scholarship for 2019. Schwarck’s research aims to help Hoosier farmers accurately assess their potassium (K) needs for their crop.

Early trials show option to trim potash needs

Someday you might use half the fertilizer and still achieve higher yields with corn. That’s what early findings show from ongoing research led by Purdue University Extension agronomist Tony Vyn. A three-year study in silty clay soils near West Lafayette, Ind., moved to the Pinney-Purdue Agricultural Center near Wanatah last fall to see if initial findings differ in the sandier soils of northwest Indiana.

Purdue professor appointed to endowed chair in crop sciences

The Purdue University Board of Trustees has appointed Tony Vyn, professor of agronomy, to the Henry A. Wallace Chair in Crop Sciences. The endowed chair is funded by Corteva Agriscience™, Agricultural Division of DowDuPont. 

Purdue University review: Modern corn hybrids are resilient

Modern corn hybrids produce more plant material and take up, on average, the same amount of nitrogen as earlier varieties, in spite of being more crowded and having less nitrogen available per plant, a Purdue University review finds.

Nutrient Balance is Necessary for Higher Global Corn Yields

Ensuring that corn absorbs the right balance of nitrogen, phosphorus and potassium is crucial to increasing global yields, a Purdue and Kansas State University study finds. A review of data from more than 150 studies from the U.S. and other regions showed that high yields were linked to production systems in which corn plants took up key nutrients at specific ratios – nitrogen and phosphorus at a ratio of 5-to-1 and nitrogen and potassium at a ratio of 1-to-1.
