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.

Figure 1. Planting into cold soil (below 50°F) when cold conditions are expected for the next 48 hours can lead to germination problems and seedlings not emerging or not emerging well. 1a. Corn seedling that started leafing out below ground and now has twisted leaves which will delay or negate normal plant development.. Figures 1b-c. Unemerged seedlings attempting to leaf out belowground. None of the seedlings shown should be counted as a productive plant.

Cold Soil Temperature and Corn Planting Windows April 12, 2018

With stormy conditions back in the picture, many growers may be concerned about planting corn into cold, wet soils? By checking weather forecasts and soil temperature at planting (in the field and online) and the cold tolerance of seed, growers can identify 48-hour windows of opportunity for planting.

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.

Potential Off-Target Dicamba Movement from Corn Applications February 15, 2018

While the new soybean dicamba herbicides were often blamed for injury to sensitive plants in 2017, a deeper look at the timing of injury and the weather conditions at those times suggests dicamba applications in corn may have contributed to plant injury in many areas. Increased management for all dicamba applications will be needed in 2018.
