This Kansas Wheat Alliance variety still has good yield potential where it’s best adapted, in south central Kansas and Oklahoma, and if it’s sprayed with a fungicide where necessary. Field reports in recent years have been better in Oklahoma, overall, than in Kansas. It can be hurt by scab, freeze injury and leaf rust. Overley is intermediate to stripe rust, which is a bit better than most other Jagger-type varieties. Overly is strongest now in far south central Kansas and in Oklahoma where head scab and shattering are not big problems. It is well suited for acid soils.

Overley does not tiller well. If it suffers freeze damage, it may not recover as quickly as better-tillering varieties. Overley has very large seed and medium-large heads. It can get tall and lodge under good conditions. It is also well suited to continuous, no-till wheat systems in that region because of its tan spot tolerance. In southern areas, Overley should be planted late to help keep it from breaking dormancy too early in the spring. Also,  it doesn’t germinate well in hot soils. Overley doesn’t get off to as fast a start in the fall as Jagger, but has better yield potential.
