Severe and erratic weather events in the southern and northern U.S. threaten soybean yield and seed quality. In southern states, hot and humid weather cause yield loss and seed quality deterioration. While in northern states, frost and asynchronous maturation commonly affect yield and seed quality. With changing weather patterns, issues common to the south or north will likely occur in other geographies as well. In 2024, our team established experiments in 15 states across the U.S. to evaluate seed quality degradation (sprouting, green stem, green seed) and seed quality (protein, oil). Experiments examined desiccants and harvest date to protect yield and seed quality. We will conduct an analysis on seed quality and composition as influenced by soybean management and weather and use our network of agronomists and Extension track-record to deploy a national education effort focused on delivering solutions through a diversified outreach approach.

Climate resilient best management practices are needed for farmers to maximize profitability while ensuring superior seed quality and composition. This project aligns with the USB priorities of Health and Nutrition and Innovation and Technology by ensuring a supply of soybean through plants resilient to weather extremes while producing a healthier seed product for domestic and international markets. Our team is working to create value for soybean farmers by developing best management practices to ensure profitability.
