Interpretive Summary:

Technical Abstract: Relay cropping soybean with winter camelina (Camelina sativa L. Crantz) and pennycress (Thlaspi arvense L.) in corn and soybean rotations in the northern Corn Belt, USA provides ecosystem services and is economically viable. However, questions remain regarding the optimum time to interseed these covers into standing corn (Zea mays L.) and soybean [Glycine max (L.) Merr.]. Therefore, a multi-location field study with sites in Iowa, Minnesota, and North Dakota was initiated in 2016 to evaluate cover crop establishment, yield, and impact on relayed soybeans across three planting times ranging from late August to late September. Initial results indicated that broadcast interseeding did not affect corn and soybean yields across sites and establishment of these covers was a greater challenge in standing corn than soybean. Cover crop establishment in 2016 tended to be best when planted at the middle seeding date (R5 in corn and R7 in soybean) in IA and MN, whereas the northerly-most site in ND, seeding earlier at the first two growth stages (R4 in corn and R6 in soybean) tended to be better.
