Armstrong Research and Demonstration Farm
Inevitably, every year soybean planting gets delayed or needs to be replanted because of weather somewhere in Iowa. Even if soybean planting starts and progresses in a timely manner, there is always the question of what maturity group should be planted. This trial was set up to determine what maturities are well suited for a given geographic location,but also how maturity selection should be adjusted as planting dates get pushed into late spring.
