Expectations for a late-emerged winter wheat crop

Many wheat fields in Kansas failed to emerge in the fall of 2022. Emergence has been highly variable all winter and spring, and some fields are still trying to emerge. Late-emerged winter wheat has considerably less yield potential than a crop that emerged at the optimum time.

Weed management considerations for thin wheat stands

Prolonged drought in much of Kansas has resulted in marginal wheat stands and a difficult decision for many farmers, especially with reasonably strong prices. Thin wheat stands will require residual herbicides to limit competition from weeds. However, if the field might be planted to another crop this spring, some residual herbicides will limit options for a subsequent crop. Learn more in this article.

Optimal corn seeding rate recommendations

The optimal corn seeding rate is a management factor that depends on the corn hybrid and its interaction with the environment. This article offers guidelines to help producers determine if their corn seeding rates need to be adjusted. Recommended seeding rates in this article attempt to account for the different growing environments in Kansas.
