Figure 1. A research plot at the university’s Eastern Nebraska Research and Extension Center (ENREC) near Mead on May 13, 2019. The entire plot is covered with no-till corn residue. The west half also is covered with a November 17 planted cereal rye cover crop. Soil temperatures 2 inches deep were recorded in each half, but were essentially the same, so are averaged in this report.

Soybean Germination/Emergence with April Planting Dates Relative to Coincident Air and Soil Temperatures in April and May

May 16, 2019
A closer look at air and soil temperatures in April and soybean germination and emergence from 10 planting dates did not find chilling injury, despite periods below 50°F. Further research is needed to better understand the imbibitional period in soybean.

With Delayed Corn Planting, Is It Time To Switch Maturities?

May 9, 2019
Research suggests that staying with a full-season hybrid until late May often provides the best yield. If planting is delayed to late May or early June, consider a medium-season CRM might be considered.

Windows of Opportunity for Corn Planting: Nebraska Data

April 24, 2019
Does early planting of corn necessarily result in higher yields? An examination of Nebraska research and data from USDA NASS sheds light on the question, indicating that, up to mid-May, other factors may affect final yield more than planting date.
