Considerations for Postemergence Dicamba-based Herbicide Applications to Corn

May 31, 2018

With postemergence herbicide applications occurring to corn, consider these best management practices to improve results and reduce the potential for off-target injury from your dicamba application.

Take Time to Set Up Nebraska Ag Water Management Equipment

May 23, 2018

As you finish planting, consider installing ETgages and soil moisture sensors before crop roots interfere. Then join the hundreds of farmers contributing their data each week to the Nebraska Agricultural Water Management Network, a valuable tool for managing your crop.

Assessing Effects of Recent Dust Storm on Emerged Corn

May 17, 2018

This week several corn fields in south central Nebraska were surveyed to assess damage and longer term effects on stands after last week's high winds and resulting dust storms. While many plants were seriously injured, many would be expected to recover.

Wheat Forage Options and Considerations

May 17, 2018

This spring many Nebraska livestock producers facing low forage supplies may be looking for new sources, such as from wheat. This Nebraska research on harvest timing suggests how to optimize feed value from wheat forage.

Is Soybean Yield Limited by Nitrogen Supply?

January 8, 2018

An article from the Proceedings of the 2018 Nebraska Extension Crop Production Clinics exploring research on whether nitrogen supply is limiting soybean yield.

Winter Wheat Progress Across the State

April 26, 2018

Winter wheat in the Nebraska Panhandle continues to be rated above average with most of the wheat rated good to excellent. Winter wheat in the west central, south central, and eastern areas is more varied, as described in this wheat progress and condition report.

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?

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.
