Abstract

Even though it is early in April, I have already gotten the first phone call inquiring, "Is it too early to plant soybean?" Looking outside the window watching the snowflakes and seeing 7 inches of snow on the ground, I know that particular grower probably appreciated that I didn't recommend planting. So how early can you plant? Well, it depends on the weather and the temperature. Previous research from the Department of Agronomy at Iowa State University shows that the optimum planting dates for full-season soybean varieties are in the last week of April and the first week of May, with yields not being significantly different between late-April and mid-May.
