Research on pennycress aims to go from weed to cash crop

Sep 07, 2023

Researchers are helping Midwest farmers explore what crops they might add to a traditional corn-soybean rotation. Pennycress is being studied for its potential to grow as a cash crop between soybeans and corn.

Illinois State University crop scientist and researcher Nicholas Heller showed farmers on tour at ISU’s University Farm in Lexington Aug. 15 some things learned, so far, about growing pennycress here.

This research is just part of the 440-acre crop and livestock farm in Lexington that welcomes about 3,000 visitors a year and helps educate 420 ISU ag students annually, said ISU agricultural professor Rob Rhykerd on the field day sponsored by the Illinois Soybean Association.

Video: Dr. Emerson Nafziger: Nitrogen Fertilizer Rates for Corn

The Crop Science Podcast Show, Dr. Emerson Nafziger from the University of Illinois breaks down decades of nitrogen research. From the evolution of N rate guidelines to how soil health and hybrid genetics influence nitrogen use efficiency, this conversation unpacks the science behind smarter fertilization. Improving how we set nitrogen fertilizer rates for rainfed corn is a key focus. Discover why the MRTN model matters more than ever, and how shifting mindsets and better data can boost yields and environmental outcomes. Tune in now on all major platforms!

"The nitrogen that comes from soil mineralization is the first nitrogen the plant sees, and its role is underestimated."

Meet the guest:

Dr. Emerson Nafziger is Professor Emeritus of Crop Sciences at the University of Illinois at Urbana-Champaign, with degrees in agronomy from Ohio State, Purdue, and Illinois. His research has focused on nitrogen rate strategies and crop productivity. He co-developed the Maximum Return to Nitrogen (MRTN) model, which is widely used across the Midwest. His research spans N response trials, hybrid interactions, crop rotation effects, and yield stability.
