Simulations of 2016 end-of-season corn yield potential for 41 sites indicate high probability of near or above-average yields in irrigated fields, but much more variability across the Corn Belt for rainfed fields. Several sites in southern and northeast Nebraska and in Iowa show a higher probability of below average yields. The article includes yield forecasts for each site, along with conditions for the period contributing to the forecasts.
Southern rust has been confirmed in samples from 10 Nebraska counties — Adams, Butler, Clay, Fillmore, Lancaster, Nuckolls, Pierce, Polk, Thayer, and Valley. All were from fields with a low incidence of disease at the time. Growers should also be scouting for rust as well as gray leaf spot, common rust, and physoderma brown spot.
Corn yield forecasts, based on Hybrid-Maize simulations and input from crop experts in 10 states, were developed for 41 sites across the Corn Belt on July 27. For irrigated corn, based on this conditions at this point in the season, there is only a low probability of below average yields. For rainfed corn, the majority of the sites studied, the results are more variable across locations. The article includes yield forecasts for each site, along with conditions for the period contributing to the forecasts.
Based on modeling corn growth stage and end-of-season yield for 41 sites in 10 Corn Belt states, researchers are forecasting potential end-of-season yield in "real time" to aid in decision-making thoughout the season. On July 14 they reported that corn has already reached or is approaching silking throughout most of Nebraska and the Corn Belt, except for corn in the northern and eastern states, where growth is running behind the rest of the region.based on modeling end-of-season corn yield for 41 sites. There is a low (<20%) probability of below-average yields at all irrigated locations, except for two sites in southeastern Nebraska. The range of forecast yields at the rainfed sites is wider. There is a relatively high probability (>75%) of above-average yield at two locations in the northern states and below-average yield at three locations. See story for predicted yields and probabilities for all the sites.
The Yield Forecasting Center will be providing in-season corn yield forecasts every two weeks starting in mid-July to aid growers and the ag industry in making management, logistics, and marketing decisions through the season. The Center consists of a core team at UNL in collaboration with agronomists and extension educators from universities throughout the Corn Belt.
As wet conditions further delay soybean planting in some areas, learn what practices may need to be adjusted and which don't to achieve a successful soybean stand.
Following rains across much of the state last week, wheat diseases appear to be increasing, based on field surveys this week. Reported diseases include powdery mildew, stripe rust, and leaf spot.
