Soybeans will be small seeded. In some cases, the seeds will be flat or oblong chips rather than developed beans. This situation happened several years ago in a dry year; the term "shrinkled" (shriveled and wrinkled) was coined to describe such soybean seeds. The small seed size relates directly to loss in yield. Areas that received late August rains will have fewer "shrinkled" seeds. Seed beans from drought areas will be small.
