Test for SCN This Fall & Select Seed Accordingly

October 31, 2016
If you noticed some areas of your soybean fields that didn't yield as well as expected, this fall would be a good time to soil test for soybean cyst nematode. In University of Nebraska research of SCN-infested fields, switching to an SCN-resistant variety increased yields as much as 6 bu/ac.

Help Us Identify Yield-Limiting Factors in Nebraska Soybean Fields

October 5, 2016
Nebraska soybean producers are being asked to answer a survey about their soybean fields and contribute to a benchmark study of current soybean production in Nebraska. Researchers from 10 north central states, including Nebraska, are collecting the data to identify factors that may be impeding growers from reaching full yield. See what they've learned in the first two years of the study and how they hope to use the information.

Soybean Aphids Found in Northeast Nebraska; Scouting Warranted

July 28, 2016

This week soybean aphids were found in several northeast Nebraska fields at low numbers. Although it has been too hot for soybean aphids to thrive, populations could quickly increase with cooler temperatures. Scouting is recommended at this time.

SCN Scouting Recommendation Changes; SCN Resistance Possible

July 8, 2016
Mid-summer is an effective time to scout for soybean cyst nematode (SCN) using either the visual or soil test method. This story describes both methods. If SCN is identified, a follow-up soil test approximately six years later can help assess effectiveness of treatment efforts as well as identify SCN resistance.
