Nebraska Extension Weed Management Field Day is June 25

Mar 27, 2025

By Natalie Jones

Growers, crop consultants, Ag professionals, extension educators, and stakeholders are encouraged to attend Nebraska Extension's Weed Management Field Day from 9.00 am to 1 pm June 25 at the University of Nebraska–Lincoln’s South Central Agricultural Laboratory near Clay Center.

The field day will include on-site demonstrations of herbicides and cover crops for weed control in corn, sorghum, and soybean. An early morning demonstration will focus on weed control in soybean followed by a demonstration of projects for weed control in corn and sorghum.

“A number of projects will be demonstrated during the field day, including weed control in XtendFlex soybean, Enlist Soybean, Roundup Ready/Liberty Link corn, and Double Team sorghum” said Extension Weed Management Specialist Amit Jhala.

New this year for participants to learn about research project aimed at terminating cereal rye before and after planting corn; hairy vetch for weed suppression in sorghum, and integrated management of volunteer corn in corn.

Certified Crop Advisor (CCA) continuing education units are available.

Lunch will be provided at noon followed by UNL dairy Store Ice cream. There is no cost to attend the field day, but participants are asked to register at http://agronomy.unl.edu/fieldday.

The South Central Agricultural Laboratory is 4.5 miles west of the intersection of Highways 14 and 6, or 12.4 miles east of Hastings on Highway 6. GPS coordinates of the field day site is 40.57539, -98.13776.

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.
