Overseeding Small Grain in Standing Soybeans vs Conventional Planting Methods1

Abstract Rye (Secale cereale L.) and wheat (Triticum aestivum L.) were overseeded in a soybean (Glycine max (L.) Merrill) crop on both Coastal Plain and Piedmont soils. This method of seeding enables the small grain crop to be planted at an optimum time rather than being subjected to a possible delay in planting caused by a late soybean harvest and/or wet fields. Rye and wheat grain yields were 53 and 75% higher, respectively, for overseeding than for late plantings.
