Influence of Planting Patterns and Times on Soybean Plant Canopy and Yield

In southern Korea, soybeans planted in May produce less seed yield than those in June, even if dry matter accumulations are more. This experiment was carried out to clarify such paradoxical relationship between dry matter accumulation and seed yield by analyzing canopy structures. Soybean seed (cv....

Summary:In southern Korea, soybeans planted in May produce less seed yield than those in June, even if dry matter accumulations are more. This experiment was carried out to clarify such paradoxical relationship between dry matter accumulation and seed yield by analyzing canopy structures. Soybean seed (cv. Daepung, maturity group) was sown by four different planting patterns with same planting density (19,047plants/10a) on May 15 and June 15. Dry matter(DM) and leaf area index (LAI) in R4 stage were higher, and yield was significantly lower in the soybean seeded in the May.
