Winter wheat yields in eastern Nebraska were quite variable in 2018, ranging from 10 to 80 bu/ac, depending on precipitation. This review of the growing season examines some of the factors affecting yields in southeast, east central, and northeast Nebraska.
Diseases continue to be absent or at very low levels in Nebraska wheat, with no reports of stripe rust or leaf rust and low levels of powdery mildew. Prevailing high temperatures and dry conditions in many areas have reduced the risk of significant disease development.
Wheat fields in southeast and south central Nebraska were green with little disease and high yield potential, based on this week's field survey. Recent rains relieved moisture stress in wheat in some areas of the state, but more rain is needed in southeast Nebraska to alleviate stress.
A survey of wheat in southeast Nebraska found diseases generally absent or at very low levels, mainly due to recent dry conditions. Continued scouting for foliar diseases is recommended, especially in areas that receive rainfall and where the wheat crop has not yet headed.
