Figure 1. Soybean pods collected from stage R7 plants (one mature pod per plant) that were opened to determine if the pod wall interior membrane was still clinging tightly to the seeds (leftmost pod), or if it was beginning to detach from the seeds (second pod), or if the membrane was now permanently attached to the pod wall (third pod). After attaining physiological maturity, seeds undergo a dry-down period from about 60% moisture to about 13% moisture. Note that the Rx.x numbers used here are pod-based stages, not plant-based stages.

Understanding Ending Reproductive Stages in Soybean

August 27, 2021

The timing of the ending R stages in soybean is governed by planting date (PD) and varietal maturity group (MG), though the date of R7 can be hastened if water stress and high temperatures prevail in August — something we are seeing in portions of Nebraska this year.

2021 Corn Yield Forecasts as of Aug. 25

August 25, 2021

In line with previous forecasts in mid-July and early August, there is no indication that this is going to be a record — and not even an above average — year for national corn yield.

2021 Corn Yield Forecasts as of Aug. 4

August 4, 2021

Below-average rainfall has increased the probability of low yield for rainfed sites in western and northern parts of the Corn Belt and central Iowa.

2021 Corn Yield Forecasts as of July 14

July 14, 2021

Although it is still too early to make strong inferences about end-of-season yields for irrigated corn, there is a relatively high probability for near-average yields for a majority of sites.

2021 Corn Yield Forecasts: Approach and Interpretation of Results

June 30, 2021

The Yield Forecasting Center (YFC) will provide real-time information on corn phenology and forecasts of corn yield potential every three weeks, starting in mid-July, to aid growers and ag industry in making management, logistics and marketing decisions through the 2021 season.
