Variety traits
Glycine max (L.) Merr.
Protein content is the primary indicator of soybean seed quality, ranging from 30% to 48% on a dry matter basis. Protein levels are critical to crop market value and exhibit a strong negative correlation with yield.
In the reference 416 varieties crop Soybean, where this is mentioned in the description.
Soybean seeds typically contain between 30% and 48% protein, with 37–38% considered the baseline requirement for the market. There is a genetic trade-off where a 1% increase in protein content can reduce yield by an average of 2% due to the high energy costs required by the plant for the biosynthesis of protein compounds.
Protein accumulation in the grain is significantly influenced by agronomic factors: the quality of seed inoculation for the formation of active nitrogen-fixing nodules, and the availability of sulfur and moisture during the pod-filling stage. Maintaining leaf canopy is a key condition, as the process of nitrogen remobilization from leaves to seeds determines the final product quality.
