AB This study evaluated how winter cover crops with various applied nitrogen rates affect net revenue and risk from no-tillage corn production. Net revenues for legume covers with no applied fertilizer nitrogen were risk inefficient. Hairy vetch with 168 kg/ha of applied nitrogen maximizes mean net revenue and is a risk efficient system for risk averse farmers. Risk averse farmers may choose to adopt a hairy vetch cover to improve net revenue, but may not reduce commercial nitrogen use. Winter wheat covers were risk inefficient for all nitrogen fertilization levels.
