Prediction Triple Effect on Soybean: Responses to Production and Grain Quality Under Elevated CO₂, High Temperature, and Drought Open
Soybean (Glycine max) is a major crop for food, feed, and bioenergy, yet its productivity and nutritional quality are threatened by climate change factors such as elevated CO₂ (eCO₂), high temperature, and drought. Here, we integrate exper…
