Map indicating how various Nebraska and Kansas sites are expected to vary from average yields.

2017 Corn Yield Forecasts as of September 20 September 21, 2017

Crop modelers wrap up their forecasts of rainfed and irrigated corn yields across the Corn Belt for 2017, noting above-average yields for about 80% of the irrigated sites and more than 60% of the rainfed sites. Irrigated yields ranged from 11%-17% over long-term averages at those sites and rainfed yields at those sites were 13%-40% above average. View data for all the sites.

Plan Harvest to Deliver Soybeans at the Optimum Moisture September 14, 2017

Most soybeans are harvested and delivered directly to an elevator instead of being placed in on-farm storage. Soybeans delivered below or above 13% moisture—the elevator standard—lose potential profit. The economics illustrated here show how harvest timing can affect potential income.

Forecast of end-of-season irrigated corn yields in Nebraska and Kansas

2017 Corn Yield Forecasts as of August 30 September 1, 2017

Forecasts for end-of-season corn yields improved across much of the Corn Belt since the early August forecast. View crop stage and yield forecasts as well as weather data. In Nebraska predictions are for near to above average corn yields for most sites, except northeast and northwest sites.

Maps showing likelihood of yield deviations for rainfed corn at various sites.

2017 Corn Yield Forecasts as of Aug. 9 August 11, 2017

Corn yield forecasts for Nebraska sites indicate near-average to above average yields for most irrigated sites. There was much more yield variability for rainfed locations where three of the sites were forecast with a 50%-100% chance of below-normal yields and three were forecast for normal yields, while one was near average.

Scout Corn Fields for Kernel Set August 4, 2017

Considering the day to day and week to week variability in weather we’ve experienced and the wide range of regional conditions across Nebraska this year, scouting fields for kernel set and overall condition may be more important than ever. Check out these corn reports from across the state.

Corn Disease Update: Southern Rust Increasing; Diplodia New to Nebraska July 27, 2017

Warm, wet conditions across Nebraska the past two weeks created optimal conditions for crop diseases. This update looks at identification and management of three diseases in corn: southern rust, which is expanding in the state, bacterial leaf streak, and diplodia, which is new to Nebraska.

Southern Rust Confirmed in Corn in 8 Eastern Nebraska Counties July 19, 2017

Southern rust has been confirmed in corn in 8 eastern Nebraska counties and growers are urged to scout vigilantly to schedule optimal timing of treatment, if needed. Most systemic fungicides can provide protection of leaves from future infections for 21-28 days.
