Abstract: ABSTRACT Increasing row crop productivity—as measured by yields per acre—is an important topic from a number of perspectives. On a global scale, increased output per unit of land is needed to meet growing world food demand. On a regional scale, investments in yield‐enhancing basic research need to result in improved yields for producers. In this research we set forth to quantify the impact of technology, precipitation, and temperature on soybean yields. Specifically, a disaggregated approach is used to model Illinois soybean yields across the nine state crop reporting districts. The results show that weather impacts are similar across the crop reporting districts; however, technology benefits accrue at statistically different rates across regions. The results provide no evidence that soybean yields in Illinois are plateauing [JEL Classifications: Q130, Q160, Q190].
