Soybean varieties are developed by state agricultural experiment stations and private industry. Performance data for many of these varieties are reported in the annual publication, Soybean Performance Report, available from county offices of Penn State Cooperative Extension. Poor-quality seed may limit yield and crop performance because of low germination, excessive foreign material, weed seed, and seed of other varieties or crops. Soybean seed is sensitive to rough handling and storage conditions. For this reason, it's suggested that bin run grain not be used for seed.
Certified seed offers the best assurance of quality.
When using noncertified seed, make sure that the seed has been cleaned and that germination and purity tests have been conducted.
