Corn, Soybean Planting Considerations for this Week’s Cold Snap April 24, 2017

With nighttime lows predicted to drop several nights this week, growers are advised to cautiously assess the potential for germination problems due to imbibitional chilling before planting. Agronomists advise checking soil temperatures in each field the day of planting as well as forecast temperatures for 24 hours (soybeans) or 48 hours (corn) after planting.

10 Years of Research Shows Benefit of Reducing Soybean Seeding Rates March 30, 2017

A review of 10 years of soybean research shows that reducing your seeding rate from 150,000 to 120,000 seeds/acre can result in a $10.69/acre savings without affecting yield (assuming a $60/unit seed cost at 140,000 seeds/unit).

Help Us Identify Yield-Limiting Factors in Nebraska Soybean Fields October 5, 2016

Nebraska soybean producers are being asked to answer a survey about their soybean fields and contribute to a benchmark study of current soybean production in Nebraska. Researchers from 10 north central states, including Nebraska, are collecting the data to identify factors that may be impeding growers from reaching full yield. See what they've learned in the first two years of the study and how they hope to use the information.

Yield Forecast Center Predicts Corn Yields Well Below USDA-NASS Projections September 22, 2016

End-of-season yield forecasts for irrigated and dryland corn across eight states in the Corn Belt indicate above average yields for 2016, but not the record-breaking yields predicted by USDA in their September forecast. While two states are forecast to have yields below the 10-year average (-1% to -4%), the remaining states showed above average yields ranging from 1% to 21% above the 10-year average.
