Regional analysis of planting date and cultivar maturity recommendations that improve soybean oil yield and meal protein concentration.

Planting date and cultivar maturity group (MG) are major management factors affecting soybean [ (L.) Merr.] yield, but their effect on seed oil and protein concentration, and in particular meal protein concentration, is less understood.

Effects of Purple Seed Stain on Seed Quality and Composition in Soybean.

Purple seed stain disease, caused by (), is a major concern in soybean ( (L.)) in Mississippi, USA, due to its effects on seed quality, reducing soybean seed grade and potential market price at elevators. Therefore, investigating the effects of purple seed stain (PSS) on seed quality (germination and vigor) and seed composition (nutrition) is critical.

Assessing Variation in US Soybean Seed Composition (Protein and Oil).

Soybean [ (L.) Merr.] seed composition and yield are a function of genetics (G), environment (E), and management (M) practices, but contribution of each factor to seed composition and yield are not well understood.
