Soybean fields in planting date study at UNL's East Campus
Planting date studies conducted on UNL's East Campus showed yield decreases of 1/4 bu/ac (2003) and 5/8 bu/ac (2004) for each day after May 1 that soybean were planted.

Amplifying Positive Impacts of Early Soybean Planting April 19, 2018

The benefits of planting soybean near May 1 are well documented. Now, what are the next steps growers can take to further expand on these benefits? Are different maturity groups warranted? What groups are typically being used in irrigated and rainfed environments in Nebraska?

Soil moisture sensor only partially installed due to dry ground

Determining Beginning Soil Moisture for Planning Decisions April 12, 2018

Soil moisture sensors installed now can provide valuable information for dryland producers who want to determine existing soil moisture level and adjust cropping or planting plans accordingly. The authors installed and will be monitoring soil moisture readings at six sites in south central Nebraska.

Cold germination test of seed

Cold Germination Test for Corn and Soybeans April 10, 2018

A cold germination test is used to evaluate the emergence of a seed lot in cold wet soils. Developed to simulate adverse field conditions, it is the most widely used vigor test for corn and soybean.

What On-Farm Research has Taught Us about Soybean Seeding Rates April 6, 2018

More than a decade of on-farm research studies in Nebraska show how soybean seeding rates (and the related input costs) can be reduced without significantly affecting yield. See what growers learned and consider whether a change might benefit your bottom line.

University Research: Ragweed Can Pose a Serious Threat to Soybean Yield March 30, 2018

Once thought to be an innocent bystander to field crop production, common ragweed can "drastically reduce soybean yields," according to University of Nebraska-Lincoln research. In dense populations, the loss was shown to be 40-76%.

Glyphosate-resistant common waterhemp in soybean without a pre-emergence herbicide with multiple sites of action.

Pre-emergence Residual Herbicides are the Foundation of Soybean Weed Control March 29, 2018

Even with new dicamba-resistant soybeans, pre-emergence, residual herbicides are needed to mitigate yield loss due to weed competition, provide a longer time for soybean to establish, and reduce selection pressure for weeds resistant to post-emergence herbicides.
