Looking Back at Corn Planting Progress and Fieldwork Day Records: 1996 -2019 June 21, 2019

How do this year's corn planting delays compare with other years here and those in Illinois. After observing fields from Nebraska to Illinois on a recent trip, agronomist Roger Elmore digs into agricultural statistics dating back to 1996 to see just how this planting season and fieldwork days compare with previous ones.

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.
