Soil erosion is a major problem in soybean production regions as crop residue is limited, leaving the soil with limited cover during the winter. Cover crops can provide protection to the soil by reducing soil particle removal due to wind and water erosion. Camelina is a short-season annual oilseed crop in the Brassicaceae family with agronomic low-input features. Because of winter camelina’s desirable agronomic traits, further research is being conducted to improve its adoption of cultivation and cover crops use. Winter rye as a cover crop can be integrated into existing corn – soybean production systems and has been recommended as a cost-effective strategy for improving environmental stewardship. The objectives of this research were to evaluate cover crop development and biomass production when interseeded into soybean cultivars with different relative maturity and to evaluate the effect of cover crop growth on soybean and HRSW grain yield.
