A University of Wisconsin weed scientist says planting green is great for suppressing weeds but doing it wrong leads to corn yield losses.
Rodrigo Werle tells Brownfield their southern Wisconsin trials show early May planted corn into green cereal rye does well but, “The moment you plant that corn crop, you want to terminate that rye immediately, because if we plant green and let that cover crop grow for another week or two weeks, this is when we see tremendous impact in our yield, and we’re talking about 40, 50, 60 bushels.”
Werle says the yield losses are not bad with April and early May planted soybeans.
