AMES, Iowa — Iowa Learning Farms will host a webinar on Wednesday, July 1, at noon about the effect of a cereal rye cover crop on corn yield.
Alison Robertson, professor and extension specialist in plant pathology and microbiology at Iowa State University, will share results from one of her research projects, which investigates the effect of planting green on corn growth and development, and seedling disease.
It is recommended that rye cover crops be terminated at least 10 days before planting corn to reduce potential yield drag in corn. However, in some years this is not possible, due to conditions at planting, or when a farmer would prefer to let the cover crop grow as long as possible for soil health and environmental benefits. This webinar will explore the benefits or disadvantages of this practice.
“Starting to incorporate cover crops on a farm may seem daunting, so our research seeks to better understand the system and provide management options to ensure new adopters are successful,” said Robertson, whose research lab focuses on seedling diseases of corn and soybean caused by oomycetes (water molds), particularly in corn and soybean planted after cover crops. “The benefits of cover crops far outweigh the disadvantages; and there are ways to manage the disadvantages.”
