Abstract
A wheat variety adoption model is developed to include neighboring Kansas Crop Reporting District (CRD) variety adoption decisions and yields. The model is estimated with wheat variety data from nine CRDs between 1974 and 2023. The regional spillovers provide more observations and greater information to producers about the potential performance and adaptability of the wheat varieties available for adoption. Regional spillovers have a strong statistical association with Kansas wheat variety adoption decisions. Policies and programs that promote variety trial locations in diverse growing conditions could provide additional useful information to wheat producers, who benefit from faster adoption of new higher-yielding varieties.
