Abstract

Planting date and variety selection are two inexpensive management practices farmers can manipulate to increase their profitability. Yet very little research is conducted on this topic. To address these questions, the North Central Soybean Research Program, funded by the Soybean Check-Off, has initiated a multi-state project. The purposes of this project are to understand the risks and benefits of planting soybean in the same planting window as corn (late April vs. mid May), and determine the optimum soybean relative maturity for soybean planting in the normal corn planting window. The overall hypothesis is that a later soybean variety planted early will yield more than normal soybean maturities planted under normal soybean planting dates.
