Southern corn rust was confirmed on corn leaf samples from Fillmore and Nuckolls counties in southern Nebraska this week. The disease is currently at very low incidence in the fields where it was identified, but can lead to significant yield loss in susceptible hybrids.
A lot of factors can affect corn pollination success, including recent and predicted high heat and high humidity. This explains how environmental conditions influence the pollination process and how a cool down later this weekend may be helpful.
Corn is still in vegetative stages across much of the Corn Belt. At this point, delayed planting doesn't appear to have affected yields at irrigated sites. Yields for rainfed sites vary considerably, with those on the western edge trending above normal.
Agronomists address how the Corn Yield Forecast Center develops yield forecasts, what to expect during the growing season, and how to use the forecasts to inform farm decisions. Tables detailing soil types and crop management for each of the 41 locations are included.
Cover crops offer many benefits for prevented planting fields; however, including them in a rotation adds another layer of complexity, particularly when it comes to plant-back restrictions for previously applied herbicides. Here's what to check before selecting a cover crop species.
Still planting corn and wanting to change to a different hybrid maturity? Here are some things to consider and a tool that can help you assess which hybrid options are likely to mature before an average fall freeze date for your location.
