This project’s main goal is to identify best early planting dates for soybean in northeast, north-central, and southeast parts of Kansas and study the impact on soybean yields under varying environmental conditions. While caution should be used in making conclusions from this limited dataset, it showed a positive yield response from planting soybeans in late March-early April for certain varieties and seeding rate combinations. The last planting date in this project is usually before most producers start planting soybeans in the respective locations. Research will continue to determine if these yield response trends are consistent.
