soybean, planting date, southeast Kansas
Optimal soybean planting in southeast Kansas usually occurs from mid-May to mid- June for full-season or late June to early July for double-cropped soybean. Planting is timed to capture fall rains and cooler temperatures during critical periods of bean development and yield formation to avoid midsummer heat and drought.
