Manni’s research, extension, and teaching program at MSU focuses on current and emerging issues in cropping systems of Michigan with an overall goal to improve the profitability and sustainability of these systems. Variety selection and improved management strategies are explored in the context of modern farming practices, climatic patterns, and economic conditions. Current research is focused on impact of planting time as well as other management decisions such as variety selection, planting methods, seed placement accuracy, seeding rates, row spacing, seed treatments, and plant-pathogen interactions in corn, soybean, and wheat-based cropping systems. Additionally, Manni oversees the Michigan corn hybrid testing program with field trials across 12 locations in the state.
