2018 Corn Yield Forecasts as of July 11: Higher Temperature Led To Faster Corn Development July 13, 2018

Corn yield forecasts and crop growth stage estimates for the US Corn Belt, based on crop modeling and local input, start up this week for 2018. Corn development is well ahead of normal, with most sites in the central and southern fringes of the Corn Belt in the silking or grain-filling stages.

2018 Corn Yield Forecasts: Approach and Interpretation of Results June 29, 2018

Here's how the Yield Forecasting Center will be developing corn yield forecasts for 41 locations across the Corn Belt during the 2018 crop season. Modeling, using Hybrid-Maize, weather data, and on-site verification help researchers estimate yields so growers can adjust management during the season, if necessary.

Impacts of Volunteer Corn on Crop Yields June 1, 2018

University research conducted in several Midwest states indicates the impact of volunteer corn on corn, soybean, dry bean, and sugarbeet yields.

Control of Volunteer Corn in Soybean and Corn June 1, 2018

Volunteer corn is a competitive weed in the corn/soybean cropping system and if not controlled, may result in a yield penalty and contribute to survival of gray leaf spot and western corn rootworm. Consider these options for managing volunteer corn in soybean and corn.

ETgage

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.

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.

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.
