Integrating winter camelina into maize and soybean cropping systems – Marisol Berti, Dulan Samarappulia, Burton L. Johnson, Russ W. Gesch – Industrial Crops & Products 2017

Summary: Currently, camelina is not used as a cover crop but it has the potential to be used as such in maize and soybean cropping systems. The objective of this study was to determine the agronomic performance of winter camelina intersown as a cover crop into standing soybean or maize prior to their harvest. Experiments were conducted in Fargo, ND in 2014, Prosper, ND, in 2015, and in Morris, MN in 2014 and 2015. Results indicate that camelina intersown after V4-V5 of maize or V3-V4 of soybean stages will likely avoid competition with the primary cash crop. Camelina establishment and winter survival was best when sown after maize and soybean harvest and tended to be greater in soybean. However, there are many unanswered questions on camelina intersowing management. New research will allow optimization of intersowing management to increase yields of both crops while enhancing ecosystem services.
