2017 Indiana Soybean Planting Date Study
The purpose of this study is to determine the optimum planting date window by planting multiple dates throughout the growing season.
Risk of a reduced stand or complete stand loss due to frost is always of concern when deciding how early to pull the soybean planter out in the spring. On the flipside, early planting allows for quicker soybean development, earlier row closure, and ultimately, more sunlight capture. Our data suggests that planting soybeans early is just as important as planting corn early. Our 20-year data has shown that the ideal soybean planting window is between April 16 and April 30 at this location.
